To get permission to access device features or data outside of your Unity application’s sandbox, there are two stages:
For some permissions, Unity automatically handles both the build-time Android App Manifest entries and runtime permission requests. For more information, see Unity-handled permissions.
An Android application can only request the user for permission to use device features or data that it declares in its Android App Manifest. This is the build-time stage of Android permission handling. For information on how to declare permissions, see Declare permissions for an application.
Note: If a plug-inA set of code created outside of Unity that creates functionality in Unity. There are two kinds of plug-ins you can use in Unity: Managed plug-ins (managed .NET assemblies created with tools like Visual Studio) and Native plug-ins (platform-specific native code libraries).

See in Glossary declares a permission in its Android App Manifest, GradleAn Android build system that automates several build processes. This automation means that many common build errors are less likely to occur. More info
See in Glossary automatically adds the permission to the final Android App Manifest during the Gradle merge stage
You can request runtime permissions at any time while the application is running. It’s best practice to request permission for restricted data or a device feature when the application requires the data/feature for the first time. You should also show the user a message that explains why the application requires the data/feature before you send the request. This is important to give users context so they are less likely to deny the permission out of confusion.
For information on how to request permission at runtime, see Request runtime permissions.
Important: If you try to request the user for a permission that the Android App Manifest doesn’t declare, the device doesn’t show the permission dialogue.
Depending on the Player SettingsSettings that let you set various player-specific options for the final game built by Unity. More info
See in Glossary and Unity APIs that the application uses, Unity automatically adds some required permissions to the Android App Manifest and sends permission requests at runtime. This also applies to any plug-ins that the application uses.
To stop Unity from automatically sending permission requests at runtime, add unityplayer.SkipPermissionsDialog to the Android App Manifest. This is useful if you want to provide information about why the application requires each permission before the user sees the permission request. In this case, you need to send the permission requests manually. For more information, see Request runtime permissions.
The following list explains which permissions Unity handles automatically:
INTERNET permission to the Android App Manifest and requests permission from the user the first time that the application uses Network.VIBRATE permission to the Android App Manifest and requests permission from the user the first time that the application uses vibration.ACCESS_NETWORK_STATE permission to the Android App Manifest and requests permission from the user the first time that the application uses Application.InternetReachability.ACCESS_FINE_LOCATION permission to the Android App Manifest and requests permission from the user the first time that the application uses location.CAMERA permission to the Android App Manifest and requests permission from the user the first time that the application uses WebCamTexture.RECORD_AUDIO permission to the Android App Manifest and requests permission from the user the first time that the application uses Microphone.
