To create a Unity application for Android, you first need to set up your Unity project to support Android. To support Android, a Unity project requires the following dependencies:
Before you get started, check Unity’s Requirements and compatibility documentation for Android to make sure you’re aware of any limitations for developing a Unity application for Android.
Unity distributes dependencies as modules which means you use the Unity Hub to install them. You can install them either when you install a new Unity Editor version, or add them to an existing Unity Editor install. To install modules:
The three modules to install are:
Unity installs Android SDK & NDK Tools and OpenJDK respectively in the
OpenJDK folders under
You should use the Unity Hub to install Android SDK & NDK tools and OpenJDK to ensure that you receive the correct versions and configurations. However, there are situations where it’s useful to change the SDK, NDK, or JDK that Unity uses to build applications for Android. For example, if you have multiple versions of Unity with the same dependencies and you don’t want to duplicate the installation of the SDK, NDK, and JDK, you can specify a shared location.
To make Unity use a custom version of a dependency:
This section contains information on which versions of each dependency each Unity version supports. Each version of Unity requires a specific version of the Android NDK and Android JDK, but there are no exact version requirements for the Android SDK.
Unity relies on tools that the Android SDK provides and different versions of the SDK usually have the same tools available. This means you can use any recent version of the SDK since they all contain the build tools that Unity requires.
Important: The only exceptions are Android SDK Build-tools versions higher than version 30. Unity doesn’t support Android SDK Build-tools versions higher than 30.
The following table shows the NDK version that each Unity version supports:
|Unity version||NDK version|
The following table shows the JDK version that each Unity version supports:
|Unity version||JDK version|
|2019.4 LTS||8 (OpenJDK version 1.8)|
|2020.3 LTS||8 (OpenJDK version 1.8)|
|2021.2||8 (OpenJDK version 1.8)|
|2021.3 LTS||8 (OpenJDK version 1.8)|
The Unity Hub installs the latest version of the Android SDK Target API that Google Play requires. If you need to use a more recent version, you can change it in the Android Player Settings. To do this:
If you select a target API version newer than the latest installed version, the Unity Android SDK Updater can automatically download and install the new version. Unity displays a prompt and you can choose to either:
If you select a target API version that isn’t installed and is older than the latest installed version, the Unity Android SDK Updater can’t perform the update and Unity displays an error message. In this case, to update the Android SDK Target API, you must use the Android sdkmanager from either Android Studio or the command-line tool. Regardless of the method you choose, make sure to select the correct Android SDK folder for Unity in the Edit > Preferences > External Tools window. For more information, refer to Customizing dependencies.
Important: On Windows, if you installed the Unity Editor in the default folder (
/Program Files/), you must run the
sdkmanager with elevated privilege (Run as Administrator) to perform the update.
In Unity, Chrome OS is part of the Android development environment. This means you can deliver new and existing Android applications to Chrome OS. Also, since many Chrome OS devices are laptops or have a laptop mode, you can use features such as mouse and keyboard input. For more information:
