有关属性的描述根据 Player UI 中的相应部分进行分组：

• Icon
• Resolution and Presentation
• Splash Image
• Other Settings
• Publishing Settings

Icon

Use the Icon section to specify icons to represent your application on the device.

设置	描述
Adaptive	Specify textures of various sizes to represent your application on devices running Android 8.0 (API level 26) or higher.
Round	Specify textures of various sizes to represent your application on devices running Android 7.1 (API level 25) or higher.
Legacy	Specify textures of various sizes to represent your application on devices running versions earlier than Android 7.1 (API level 25).

Resolution and Presentation

Use the Resolution and Presentation section to customize aspects of the screen’s appearance.

设置		描述
Fullscreen Mode		Specifies how the window appears on the device. This sets the default window mode at startup.
	Fullscreen Window	The application window fills the full-screen native resolution of the device. To fill the full-screen window, Unity scales the application contents. Resolution Scaling Mode controls how Unity scales the contents. In this mode, the navigation bar is always hidden.
	Windowed	The application uses a standard, non-full-screen, movable window. The size of the window depends on the application’s resolution. In this mode, the window is resizable by default. To disable this, disable Resizable Window.
Resizable Window		Indicates whether the user can resize the application’s window. This setting enables multi-window capabilities in your application on Android phones and tablets. For more information, refer to Google’s developer documentation.
Default Window Width		The default width of the application window in pixels. This option is only available if the Fullscreen Mode is set to Windowed.
Default Window Height		The default height of the application window in pixels. This option is only available if the Fullscreen Mode is set to Windowed.
Minimum Window Width		The minimum width of the application window in pixels. This option is only available if the Fullscreen Mode is set to Windowed.
Minimum Window Height		The minimum height of the application window in pixels. This option is only available if the Fullscreen Mode is set to Windowed.
Hide Navigation Bar		Indicates whether to hide the navigation bar that appears at the top of the window.
Render outside safe area		Indicates whether the application should use all available screen space to render, including areas of the display that are cut out (notched). For more information, refer to Android’s display cutout support documentation.
Optimized Frame Pacing		Indicates whether Unity should evenly distribute frames for less variance in framerate. Enable this option to create a smoother experience.
Run In background		Enable this option to not pause the application when it loses focus. When disabled, the application pauses when it loses focus.

Other Resolution and Presentation settings are grouped under the following sections:

• Resolution Scaling
• Supported Aspect Ratio
• Orientation
• Allowed Orientations for Auto Rotation
• Other

Resolution Scaling

Use the Resolution Scaling section to customize settings relating to screen resolution scaling. Using a resolution lower than the device’s native resolution can improve performance and battery life.

设置		描述
Resolution Scaling Mode		Specifies whether and how the application scales its resolution. You can set the scaling to be equal to or lower than the native screen resolution. Using a lower resolution can improve performance and battery life.
	Disabled	Doesn’t apply resolution scaling and the application renders to the device’s native screen resolution.
	FixedDPI	Applies resolution scaling using a target DPI. Use this to optimize performance and battery life or target a specific DPI setting.
	Letterboxed	Adds black bars to the rendered output so the content doesn’t stretch. This process is called letterboxing.
Target DPI		The resolution of the application. If the device’s native screen DPI is higher than this value, Unity downscales the application’s resolution to match this setting. To calculate the scale, Unity uses the following: min(Target DPI * Factor / Screen DPI, 1) Where Factor is the Resolution Scaling Fixed DPI Factor from Quality settings.Note: This option only appears when you set Resolution Scaling Mode to Fixed DPI.
Reset resolution on window resize		Indicates whether to set the screen resolution to the new native window size when the native window size changes. If you set Resolution Scaling Mode to Fixed DPI, Unity recalculates the resolution based on Fixed DPI property.
Blit Type		Controls whether to use a blit to render the final image to the screen. Using a blit is compatible with most devices but is usually slower than not using a blit.
	Always	Unity renders to an offscreen buffer and then uses a blit to copy the contents of the buffer to the device’s framebuffer. This is compatible with most devices but is usually slower than not using blit.
	Never	Unity renders to the framebuffer provided by the device’s operating system. If this fails, the application prints a one-time warning to the device log. This is usually faster than using blit, but it isn’t compatible with all devices.
	Auto	Unity renders to the framebuffer provided by the device’s operating system if possible. If this fails, Unity prints a warning to the device console and uses a blit to render the final image to the screen.

Supported Aspect Ratio

Use the Supported Aspect Ratio section to customize settings relating to which device aspect ratios to support.

设置		描述
Aspect Ratio Mode		Specifies the largest aspect ratio the application supports. If the device’s aspect ratio is greater than this aspect ratio, Unity uses this aspect ratio for the application and adds black bars so the application doesn’t stretch..
	Legacy Wide Screen (1.86)	The application supports aspect ratios up to Android’s legacy wide-screen aspect ratio.
	Native Aspect Ratio	The application supports aspect ratios up to Android’s native aspect ratio.
	Custom	The application supports aspect ratios up to the aspect ratio you set in Up To.
Up To		The custom maximum aspect ratio. This setting only appears when you set Aspect Ratio Mode to Custom.

Orientation

Use the Orientation section to customize settings relating to the orientation of the application on the device.

从 Default Orientation 下拉菜单中选择游戏的屏幕方向：

设置		描述
Default Orientation		Specifies the screen orientation the application uses. Note: Unity shares the value you set for this setting between Android and iOS.
	Portrait	The application uses portrait screen orientation where the bottom of the application’s window aligns with the bottom of the device’s screen.
	Portrait Upside Down	The application uses portrait screen orientation where the bottom of the application’s window aligns with the top of the device’s screen.
	Landscape Right	The application uses landscape screen orientation where the right side of the application’s window aligns with the bottom of the device’s screen.
	Landscape Left	The application uses landscape screen orientation where the right side of the application’s window aligns with the top of the device’s screen.
	Auto Rotation	The screen can rotate to any of the orientations you specify in the Allowed Orientations for Auto Rotation section.

Allowed Orientations for Auto Rotation

Use the Allowed Orientations for Auto Rotation section to specify which orientations the application supports when you set Default Orientation to Auto Rotation. This is useful, for example, to lock the application to landscape orientation but allow the user to switch between landscape left and landscape right.

This section only appears when you set Default Orientation to Auto Rotation.

设置	描述
Portrait	Indicates whether the application supports portrait screen orientation where the bottom of the application’s window aligns with the bottom of the device’s screen.
Portrait Upside Down	Indicates whether the application supports portrait screen orientation where the bottom of the application’s window aligns with the top of the device’s screen.
Landscape Right	Indicates whether the application supports landscape screen orientation where the right side of the application’s window aligns with the bottom of the device’s screen.
Landscape Left	Indicates whether the application supports landscape screen orientation where the right side of the application’s window aligns with the top of the device’s screen.

Other

The Resolution and Presentation section also contains the following general settings.

设置		描述
Use 32-bit Display Buffer		Indicates whether the display buffer holds 32-bit color values instead of 16-bit color values. Enable this setting if you see banding, or need alpha values in post-processing effects. Some post-processing effects require this because they create Render Textures in the same format as the display buffer.
Disable Depth and Stencil		Indicates whether to disable depth and stencil buffers.
Render Over Native UI		Indicates whether to render on top of native UI on Android or iOS. For this setting to take effect, set your Camera’s Clear Flags to use a solid color with an alpha value lower than 1.
Show Loading Indicator		Specifies if and how the loading indicator appears.
	Don’t Show	The loading indicator doesn’t appear.
	Large	A large loading indicator appears.
	Inversed Large	A large loading indicator appears with inversed color.
	Small	A small loading indicator appears.
	Inversed Small	A small loading indicator appears with inversed color.

Splash Image

Use the Virtual Reality Splash Image setting to select a custom splash image for Virtual Reality displays. For information on common Splash Screen settings, refer to Splash Screen.

以下是通用 Splash Screen 设置，可以设置特定于 Android 的 Static Splash Image 选项。

设置		描述
Image		Specifies the texture that the application uses for the Android splash screen. The standard size for the splash screen image is 320x480.
Scaling		Specifies how to scale the splash image to fit the device’s screen.
	Center (only scale down)	Draws the image at its native size unless it’s too large, in which case Unity scales the image down to fit.
	Scale to Fit (letter-boxed)	Scales the image so that the longer dimension fits the screen size exactly. Unity fills in the empty space around the sides in the shorter dimension in black.
	Scale to Fill (cropped)	Scales the image so that the shorter dimension fits the screen size exactly. Unity crops the image in the longer dimension.

渲染

使用这些设置可自定义 Unity 针对 Android 平台渲染游戏的方式。

Property	Description
Color Space	Choose which color space to use for rendering. For more information, refer to Linear rendering overview.
	Gamma	Gamma color space is typically used for calculating lighting on older hardware restricted to 8 bits per channel for the framebuffer format. Even though monitors today are digital, they might still take a gamma-encoded signal as input.
	Linear	Linear color space rendering gives more precise results. When you select to work in linear color space, the Editor defaults to using sRGB sampling. If your Textures are in linear color space, you need to work in linear color space and deactivate sRGB sampling for each Texture.
Auto Graphics API	Disable this option to manually pick and reorder the graphics APIs. By default, this option is enabled, and Unity tries to use Vulkan. If the device doesn’t support Vulkan, Unity falls back to GLES3.2, GLES3.1 or GLES3.0. Important: Unity adds the GLES3.1/GLES3.1+AEP/GLES3.2 requirement to your Android App Manifest only if you enable Auto Graphics API or if Graphics APIs includes OpenGLES3.
Graphics APIs	Specifies which graphics APIs the application supports. Unity tries to use the graphics API at the top of the list first and, if the device doesn’t support it, Unity falls back to the next graphics APIs in the list. This property is visible only when Auto Graphics API is set to false.
	Vulkan	Adds Vulkan as an API to target.
	OpenGLES3	Adds OpenGLES 3 as an API to target.
Require ES3.1	Indicates whether to require that the minimum OpenGL ES 3 minor version is 3.1. This property is visible only if you enable Auto Graphics API or if Graphics APIs includes OpenGLES3.
Require ES3.1+AEP	Indicates whether to require that the minimum OpenGL ES 3 minor version is 3.1+AEP. This property is visible only if you enable Auto Graphics API or if Graphics APIs includes OpenGLES3.
Require ES3.2	Indicates whether to require that the minimum OpenGL ES 3 minor version is 3.2. This property is visible only if you enable Auto Graphics API or if Graphics APIs includes OpenGLES3.
Color Gamut	You can add or remove color gamuts to use for rendering. Click the plus (+) icon to see a list of available gamuts. A color gamut defines a possible range of colors available for a given device (such as a monitor or screen). The sRGB gamut is the default (and required) gamut.
Multithreaded Rendering	Enable this option to move graphics API calls from Unity’s main thread to a separate worker thread. This can help to improve performance in applications that have high CPU usage on the main thread.
Static Batching	Enable this option to use static batching.
Dynamic Batching	Check this box to use Dynamic Batching on your build (enabled by default).
Compute Skinning	Enable this option to use DX11/DX12/ES3 GPU compute skinning, which frees up CPU resources.
Graphics Jobs (Experimental)	Enable this option to instruct Unity to offload graphics tasks (render loops) to worker threads running on other CPU cores. This is intended to reduce the time spent in Camera.Render on the main thread, which is often a bottleneck. Note: This feature is experimental. It may not deliver a performance improvement for your project, and may introduce new crashes.
Texture compression formats	Choose between ASTC, ETC2 and ETC (ETC1 for RGB, ETC2 for RGBA), DXTC and DXT + RGTC(BC4, BC5). Refer to texture compression format overview for more information on how to pick the right format. It’s possible to add multiple texture compression formats to this list for texture compression targeting support, however you can’t have both DXT and DXT + RGTC(BC4, BC5) in this list at the same time. If you enable texture compression targeting, Unity also enables, Split Application Binary. Refer to Texture compression settings for more details on how this interacts with the texture compression setting in the Build Settings. Note: If you export or build your application as an APK, Unity only uses the first texture compression format in this list.
Normal Map Encoding	Choose XYZ or DXT5nm-style to set the normal map encoding. This setting affects the encoding scheme and compression format used for normal maps. DXT5nm-style normal maps are of higher quality, but more expensive to decode in shaders.
Lightmap Encoding	Defines the encoding scheme and compression format of the lightmaps. You can choose from Low Quality, Normal Quality, or High Quality
HDR Cubemap Encoding	Defines the encoding scheme and compression format of the HDR Cubemaps. You can choose from Low Quality, Normal Quality, or High Quality. For more information, refer to Lightmaps: Technical information.
Lightmap Streaming	Enable this option to use Mipmap Streaming for lightmaps. Unity applies this setting to all lightmaps when it generates them. Note: To use this setting, you must enable the Texture Streaming Quality setting.
Streaming Priority	Sets the priority for all lightmaps in the Mipmap Streaming system. Unity applies this setting to all lightmaps when it generates them. Positive numbers give higher priority. Valid values range from –128 to 127.
Frame Timing Stats	Enable this option to gather CPU/GPU frame timing statistics.
Virtual Texturing	Indicates whether to enable Virtual Texturing. Note: Virtual Texturing isn’t compatible with Android.
Shader precision model	Controls the default precision of samplers used in shaders. For more information, refer to Shader data types and precision.
360 Stereo Capture	Indicates whether Unity can capture stereoscopic 360 images and videos. For more information, refer to Stereo 360 Image and Video Capture.Note: 360 stereoscopic capturing isn’t compatible with Android.
Load/Store Action Debug Mode	Highlights undefined pixels that might cause rendering problems on mobile platforms. This affects the Unity Editor Game view, and your built application if you select Development Build in Build Settings. Refer to LoadStoreActionDebugModeSettings for more information.
Editor Only	Indicates whether the Load/Store Action Debug Mode only runs in the Unity Editor. This property is visible only when Load/Store Action Debug Mode is set to true.

Vulkan Settings

Property	Description
SRGB Write Mode	Enable this option to allow Graphics.SetSRGBWrite() renderer to toggle the sRGB write mode during runtime. That is, if you want to temporarily turn off Linear-to-sRGB write color conversion, you can use this property to achieve that. Enabling this has a negative impact on performance on mobile tile-based GPUs; therefore, do NOT enable this for mobile.
Number of swapchain buffers	Set this option to 2 for double-buffering, or 3 for triple-buffering to use with Vulkan renderer. This setting may help with latency on some platforms, but in most cases you should not change this from the default value of 3. Double-buffering might have a negative impact on performance. Do not use this setting on Android.
Acquire swapchain image late as possible	If enabled, Vulkan delays acquiring the backbuffer until after it renders the frame to an offscreen image. Vulkan uses a staging image to achieve this. Enabling this setting causes an extra blit when presenting the backbuffer. This setting, in combination with double-buffering, can improve performance. However, it also can cause performance issues because the additional blit takes up bandwidth.
Recycle command buffers	Indicates whether to recycle or free CommandBuffers after Unity executes them.
Apply display rotation during rendering	Enable this to perform all rendering in the native orientation of the display. This has a performance benefit on many devices. For more information, see documentation on Framebuffer orientation.

Identification

属性	功能
Override Default Package Name	Indicates whether to override the default package name for your application. Note: This setting affects macOS, iOS, tvOS, and Android.
Package Name	Set the application ID, which uniquely identifies your app on the device and in Google Play Store. The application ID must follow the convention com.YourCompanyName.YourProductName and must contain only alphanumeric and underscore characters. Each segment must start with an alphabetical character. For more information, refer to Set the application ID. Important: Unity automatically removes any invalid characters you type. To set this property, enable Override Default Package Name.
Version	输入捆绑包的构建版本号，用于标识捆绑包的迭代（已发布或未发布）。版本以通用格式指定，该格式包含以点号分隔的数字的字符串（例如，4.3.2）。（在 iOS 和 Android 之间共享。）
Bundle Version Code	内部版本号。此数字仅用于确定一个版本是否比另一个版本更新，数字更大表示版本越新。这不是向用户显示的版本号；向用户显示的版本号由 versionName 属性设置。该值必须设置为整数，例如“100”。您可以根据需要定义，只要每个后续版本具有更高的数字即可。 例如，它可以是构建版本号。或者，可以通过在低 16 位和高 16 位分别编码“x”和“y”将“x.y”格式的版本号转换为整数。或者，每次发布新版本时，只需将数字加一。 如果启用了 Split APKs by target architecture，请将此数字保持在 100000 以下。每个 APK 必须具有唯一的版本代码，因此 Unity 为 ARMv7 添加 100000，为 ARM64 添加 200000。
Minimum API Level	运行应用程序所需的最低 Android 版本（API 级别）。
Target API Level	编译应用程序针对的目标 Android 版本（API 级别）。

配置

Property	Description
Scripting Backend	Choose the scripting backend you want to use. The scripting backend determines how Unity compiles and executes C# code in your Project.
	Mono	Compiles C# code into .NET Common Intermediate Language (CIL) and executes that CIL using a Common Language Runtime. For more information, refer to Mono.
	IL2CPP	Compiles C# code into CIL, converts the CIL to C++ and then compiles that C++ into native machine code, which executes directly at runtime. For more information, refer to IL2CPP.
API Compatibility Level	Choose which .NET APIs you can use in your project. This setting can affect compatibility with third-party libraries. However, it has no effect on Editor-specific code (code in an Editor directory, or within an Editor-specific Assembly Definition). Tip: If you are having problems with a third-party assembly, you can try the suggestion in the API Compatibility Level section below.
	.Net Framework	Compatible with the .NET Framework 4 (which includes everything in the .NET Standard 2.0 profile plus additional APIs). Choose this option when using libraries that access APIs not included in .NET Standard 2.0. Produces larger builds and any additional APIs available aren’t necessarily supported on all platforms. For more information, refer to Referencing additional class library assemblies.
	.Net Standard 2.1	Produces smaller builds and has full cross-platform support.
Editor Assemblies Compatibility Level	Select which .NET APIs to use in your Editor assemblies.
	.NET Framework	Compatible with the .NET Framework 4 (which includes everything in the .NET Standard 2.1 profile plus additional APIs). Choose this option when using libraries that access APIs not included in .NET Standard 2.1. Produces larger builds and any additional APIs available aren’t necessarily supported on all platforms. For more information, refer to Referencing additional class library assemblies.
	.NET Standard	Compatible with .NET Standard 2.1. Produces smaller builds and has full cross-platform support.
IL2CPP Code Generation	Defines how Unity manages IL2CPP code generation. Note: To use this, set Scripting Backend to IL2CPP.
C++ Compiler Configuration	Choose the C++ compiler configuration used when compiling IL2CPP generated code.
	Debug	Debug configuration turns off all optimizations, which makes the code quicker to build but slower to run.
	Release	Release configuration enables optimizations, so the compiled code runs faster and the binary size is smaller but it takes longer to compile.
	Master	Master configuration enables all possible optimizations, squeezing every bit of performance possible. For instance, on platforms that use the MSVC++ compiler, this option enables link-time code generation. Compiling code using this configuration can take significantly longer than it does using the Release configuration. Unity recommends building the shipping version of your game using the Master configuration if the increase in build time is acceptable.
Use incremental GC	Uses the incremental garbage collector, which spreads garbage collection over several frames to reduce garbage collection-related spikes in frame duration. For more information, refer to Automatic Memory Management.
Allow downloads over HTTP	Indicates whether to allow downloading content over HTTP. The default option is Not allowed due to the recommended protocol being HTTPS, which is more secure.
	Not Allowed	Never allow downloads over HTTP.
	Allowed in Development Builds	Only allow downloads over HTTP in development builds.
	Always Allowed	Allow downloads over HTTP in development and release builds.
Mute Other Audio Sources	Indicates whether your Unity application should stop audio from applications running in the background. Otherwise, Audio from background applications continues to play alongside your Unity application.
Target Architectures	Specifies which architecture to target.
ARMv7	Enable support for ARMv7 architecture.
ARM64	Enable support for ARM64 architecture.
x86 (ChromeOS)	Enable support for x86 architecture.
x86–64 (ChromeOS and Magic Leap 2)	Enable support for x86–64 architecture.
Enable Armv9 Security Features for Arm64	Enable Pointer Authentication (PAuth, PAC) and Branch Target Identification (BTI) for Arm64 builds. This property is visible only when Arm64 is set to true.
Split APKs by target architecture	Enable this option to create a separate APK for each CPU architecture selected in Target Architectures. This makes download size smaller for Google Play Store users. This is primarily a Google Play store feature and may not work in other stores. For more details, refer to Multiple APK Support.
Target Devices	Specifies the target devices on which the APK is allowed to run.
	All Devices	The APK is allowed to run on all Android and ChromeOS devices.
	Phones, Tablets, and TV Devices Only	The APK is allowed to run on Android phones, tablets, and TVs, but not on ChromeOS devices.
	ChromeOS Devices Only	The APK is allowed to run on ChromeOS devices, but not on Android phones or tablets.
Install Location	Specifies application install location on the device (for detailed information, refer to Android Developer documentation on install locations.
	Automatic	Let the operating system decide. User will be able to move the app back and forth.
	Prefer External	Install the application to external storage (SD card) if possible. The operating system doesn’t guarantee it; if not possible, the app will be installed to internal memory.
	Force Internal	Force the application to be installed to internal memory. The user will be unable to move the app to external storage.
Internet Access	Choose whether to always add the networking (INTERNET) permission to the Android App Manifest, even if you are not using any networking APIs. Set to Require by default for development builds.
	Auto	Only add the internet access permission if you are using a networking API.
	Require	Always add the internet access permission.
Write Permission	Choose whether to enable write access to the external storage (such as the SD card) and add a corresponding permission to the Android App Manifest. Set to External(SDCard) by default for development builds.
	Internal	Only grant write permission to internal storage.
	External(SDCard)	Enable write permission to external storage.
Filter Touches When Obscured	Enable this option to discard touches received when another visible window is covering the Unity application. This is to prevent tapjacking.
Sustained Performance Mode	Enable this option to set a predictable and consistent level of device performance over longer periods of time, without thermal throttling. Overall performance might be lower when this setting is enabled. Based on the Android Sustained Performance API.
Maximum Java Heap Size	Set the maximum Java heap size to user for building (in megabytes). Defaults to 4096.
Low Accuracy Location	Enable this option to use low accuracy values with Android location APIs instead.
ChromeOS Input Emulation	ChromeOS’s default behaviour is to convert mouse and touchpad input events into touchscreen input events. Un-check this setting to disable the default behavior.
Android TV Compatibility	Enable this option to mark the application as Android TV compatible.
Android Game	Enable this option to mark the output package (APK) as a game rather than a regular application. This property is visible only when Android TV Compatibility is set to true.
Android Gamepad Support Level	Choose the level of support your application offers for a gamepad. This property is visible only when Android TV Compatibility is set to true.
	Works with D-Pad	The application is fully operational with a D-pad. No gamepad is needed.
	Supports Gamepad	The application works with a gamepad, but doesn’t require it.
	Requires Gamepad	The application requires a gamepad to use.
Warn about App Bundle size	Enable this option to receive a warning when the size of the Android App Bundle exceeds a certain threshold. This option is selected by default and you can only configure it if you enable the Build App Bundle (Google Play) option in the Build settings.
App Bundle size threshold	Enter a size in Mb. When your App Bundle exceeds this size, Unity will display a warning.
Application Entry Point	The application entry points to generate for your application. For more information, refer to Android application entry points.
Activity	Generate an Activity application entry point.
GameActivity	Generate a GameActivity application entry point.
Active Input Handling	Choose how to handle input from users.
	Input Manager (Old)	Uses the traditional Input settings.
	Input System Package (New)	Uses the Input system. This option requires you to install the InputSystem package.
	Both	Use both systems.

Shader Variant Loading

Use these settings to control how much memory shaders use at runtime.

属性	描述
Default chunk size (MB)	Sets the maximum size of compressed shader variant data chunks Unity stores in your built application for all platforms. The default is 16. For more information, refer to Shader loading.
Default chunk count	Sets the default limit on how many decompressed chunks Unity keeps in memory on all platforms. The default is 0, which means there’s no limit.
Override	Enables overriding Default chunk size and Default chunk count for this build target.
Chunk size (MB)	Overrides the value of Default chunk size (MB) on this build target.
Chunk count	Overrides the value of Default chunk count on this build target.

API Compatibility Level

You can choose your mono API compatibility level for all targets. Sometimes a third-party .NET library uses functionality that’s outside of your .NET compatibility level. To understand what’s going on in such cases, and how to best fix it, try following these suggestions:

1. Install ILSpy for Windows.
2. Drag the .NET assemblies for the API compatibility level that you are having issues with into ILSpy. You can find these under Frameworks/Mono/lib/mono/YOURSUBSET/.
3. 拖入第三方程序集。
4. 右键单击第三方程序集并选择 Analyze。
5. In the analysis report, inspect the Depends on section. The report highlights anything that the third-party assembly depends on, but that is not available in the .NET compatibility level of your choice in red.

Script Compilation

属性	描述
Scripting Define Symbols	Sets custom compilation flags. For more details, refer to Platform dependent compilation.
Additional Compiler Arguments	Adds entries to this list to pass additional arguments to the Roslyn compiler. Use one new entry for each additional argument. To create a new entry, click Add (+). To remove an entry, click Remove (-). When you have added all desired arguments, click Apply to include your additional arguments in future compilations. Click Revert to reset this list to the most recent applied state.
Suppress Common Warnings	Indicates whether to display the C# warnings CS0169 and CS0649.
Allow ‘unsafe’ Code	Enables support for compiling ‘unsafe’ C# code in a pre-defined assembly (for example, Assembly-CSharp.dll). For Assembly Definition Files (.asmdef), click on one of your .asmdef files and enable the option in the Inspector window that appears.
Use Deterministic Compilation	Indicates whether to prevent compilation with the -deterministic C# flag. With this setting enabled, compiled assemblies are byte-for-byte the same each time they’re compiled. For more information, refer to C# Compiler Options that control code generation.

Optimization

Property	Description
Prebake Collision Meshes	Adds collision data to Meshes at build time.
Preloaded Assets	Sets an array of Assets for the player to load on startup. To add new Assets, increase the value of the Size property and then set a reference to the Asset to load in the new Element box that appears.
Strip Engine Code	Enable this option if you want the Unity Linker tool to remove code for Unity Engine features that your Project doesn’t use. This setting is only available with the IL2CPP scripting backend. Most apps do not use every available DLL. This option strips out DLLs that your app doesn’t use to reduce the size of the built Player. If your app is using one or more classes that would normally be stripped out under your current settings, Unity displays a debug message when you try to build the app.
Managed Stripping Level	Chooses how aggressively Unity strips unused managed (C#) code. When Unity builds your app, the Unity Linker process can strip unused code from the managed DLLs your Project uses. Stripping code can make the resulting executable smaller, but can sometimes remove code that’s in use. For more information about these options and bytecode stripping with IL2CPP, refer to ManagedStrippingLevel.
	Minimal	Use this to strip class libraries, UnityEngine, Windows Runtime assemblies, and copy all other assemblies.
	Low	Remove unreachable managed code to reduce build size and Mono/IL2CPP build times.
	Medium	Run UnityLinker to reduce code size beyond what Low can achieve. You might need to support a custom link.xml file, and some reflection code paths might not behave the same.
	High	UnityLinker will strip as much code as possible. This will further reduce code size beyond what Medium can achieve but managed code debugging of some methods might no longer work. You might need to support a custom link.xml file, and some reflection code paths might not behave the same.
Enable Internal Profiler (Deprecated)	This feature is deprecated and will be retired in a future version of Unity. Use the Profiler window instead (menu: Window > Analytics > Profiler). The Profiler collects application performance data and prints a report to the console. The report contains the number of milliseconds each Unity subsystem takes to execute on each frame, averaged across 30 frames.
Vertex Compression	Sets vertex compression per channel. This affects all the meshes in your project. Typically, Vertex Compression is used to reduce the size of mesh data in memory, reduce file size, and improve GPU performance. For more information on how to configure vertex compression and limitations of this setting, refer to Compressing mesh data.
Optimize Mesh Data	Enable this option to strip unused vertex attributes from the mesh used in a build. This option reduces the amount of data in the mesh, which can help reduce build size, loading times, and runtime memory usage. Warning: If you have this setting enabled, don’t change material or shader settings at runtime. For more information, refer to PlayerSettings.stripUnusedMeshComponents.
Texture MipMap Stripping	Enables mipmap stripping for all platforms. It strips unused mipmaps from Textures at build time. Unity determines unused mipmaps by comparing the value of the mipmap against the quality settings for the current platform. If a mipmap value is excluded from every quality setting for the current platform, then Unity strips those mipmaps from the build at build time. If QualitySettings.masterTextureLimit is set to a mipmap value that has been stripped, Unity will set the value to the closest mipmap value that hasn’t been stripped.

Logging

选择在特定上下文中允许的日志记录类型。

• Select your preferred stack trace method by enabling the option that corresponds to each Log Type (Error, Assert, Warning, Log, and Exception) based on the type of logging you require. For example:
  
  • ScriptOnly: Logs only when running scripts.
    
  • Full: Logs all the time.
    
  • None: No logs are ever recorded.
    

See stack trace logging for more information.

Use the Keystore Manager window to create, configure and load your keys and keystores. You can load existing keystores and keys from either the Keystore Manager or the main Android Publishing panel. If you choose to load these from inside the Keystore Manager, Unity automatically fills the Project Keystore and Project Key fields. For further information, refer to the documentation on Keystore Manager.

Project Keystore

A keystore is a container that holds signing keys for application security. For details, refer to Android developer documentation: Android keystore system.

Use the Project Keystore settings to choose which keystore to use for the open project. When you load a keystore, Unity loads all the keys in that keystore. To load and use an existing keystore in your open project:

1. 启用 Custom Keystore。
2. 打开 Select 下拉列表，选择 Browse，然后从文件系统中选择密钥库。
3. 输入您的密钥库密码。

如果没有现有密钥库，请将 Custom Keystore 保留为禁用状态。

Unity uses a debug keystore to sign your application. A debug keystore is a working keystore. It allows you to sign the application and to test it locally. However, the app store will decline apps signed in this way. This is because the app store is unable to verify the validity and ownership of the application using a debug keystore.

属性	描述
Custom Keystore	启用 Custom Keystore 可加载和使用现有密钥库。
Select	When Custom Keystore is enabled, use this to select the keystore you want to use. The keystores below the partition in the Select dropdown are stored in a predefined dedicated location. For more details, refer to Choose the keystore location.
路径	无需输入密钥库路径。Unity 会基于所选择的密钥库提供此路径。
Password	输入密钥库密码以加载所选的密钥库。

Project Key

When you load a keystore, Unity loads all the keys in that keystore. Use the Project Key settings to choose one key from that keystore to use as the active key for the open project.

属性	描述
Alias	选择要用于打开的项目的密钥。
Password	输入密钥密码。

Build

By default, Unity builds your application with the manifest files, Gradle templates and Proguard files provided with the Unity installation. Use the Build section of the Android Publishing Settings to change these.

To use a custom manifest file, Gradle template or Proguard file:

1. 启用相应的复选框。Unity 会在项目中创建一个默认文件，文件位置会出现在复选框下方。
2. 打开新文件并进行更改。
3. 保存对此文件的更改。Unity 下次构建应用程序时会自动使用保存到此文件的更改。

Build 部分中的设置仅适用于当前项目的构建过程。

属性	描述
Upgrade templates to C#	Opens the Android Templates Upgrader window which you can use to upgrade your custom Gradle template files to use the Android Project Configuration Manager.
Custom Main Manifest	Customizable version of the Android LibraryManifest.xml file. This file contains important metadata about your Android application. For more information about the responsibilities of the Main/Unity Library Manifest, refer to Unity Library Manifest.
Custom Unity Launcher Manifest	Customizable version of the Android LauncherManifest.xml file. This file contains important metadata about your Android application’s launcher. For more information about the responsibilities of the Unity Launcher Manifest, refer to Unity Launcher Manifest.
Custom Main Gradle Template	Customizable version of the mainTemplate.gradle file. This file contains information on how to build your Android application as a library. For more information, refer to the documentation on Gradle project files.
Custom Launcher Gradle Template	Customizable version of the launcherTemplate.gradle file. This file contains instructions on how to build your Android application. For more information, refer to the documentation on Gradle project files.
Custom Base Gradle Template	Customizable version of the baseProjectTemplate.gradle file. This file contains configuration that is shared between all other templates and Gradle projects. For more information, refer to the documentation on Gradle project files.
Custom Gradle Properties Template	Customizable version of the gradle.properties file. This file contains configuration settings for the Gradle build environment. This includes: • The JVM (Java Virtual Machine) memory configuration. • A property to allow Gradle to build using multiple JVMs. • A property for choosing the tool to do the minification. • A property to not compress native libs when building an app bundle.
Custom Gradle Settings Template	Customizable version of the settingsTemplate.gradle file. This file contains declaration of artifact repositories to resolve external dependencies required for your application.
Custom Proguard File	Customizable version of the proguard.txt file. This file contains configuration settings for the minification process. If minification removes some Java code which should be kept, you should add a rule to keep that code in this file. For more information refer to the documentation on Minification.

Minify

Minification is a process which shrinks, obfuscates and optimizes the code in your application. It can reduce the code size and make the code harder to disassemble. Use the Minify settings to define when and how Unity should apply minification to your build.

In most cases, it’s good practice to only apply minification to release builds, and not debug builds. This is because minification takes time, and can make the builds slower. It can also make debugging more complicated due to the optimization that the code undergoes.

Note: If the Java code is referenced via reflection, the minification process (R8/Proguard) cannot infer that the code is in use and strips that code. You can use Custom Proguard File to retain the code that you require.

Minify 部分中的设置仅适用于当前项目的构建过程。

属性	描述
Release	如果希望 Unity 在发布构建中缩小应用程序的代码，请启用此复选框。
Debug	如果希望 Unity 在调试构建中缩小应用程序的代码，请启用此复选框。

Split Application Binary

启用 Split Application Binary 选项可将输出包拆分为主包 (APK) 和扩展包 (OBB) 包。如果要发布大于 100 MB 的应用程序，则 Google Play 应用商店需要此功能。

Report Dependencies in App Bundle

Enable this option to include information about dependencies in App Bundle if you’re planning to build your application as Android App Bundle (AAB) for Google Play. For more information, refer to Report App Dependencies section.

Note: You can only interact with this setting if you enable Build App Bundle (Google Play) option in Android Build Settings.
