Android applications declare what permissions they require in their Android App Manifest. This page explains how to manage permissions for an Android application. For a list of the possible permissions, see Manifest.permission.
You can use one of the following methods to modify the Android App Manifest file and manage permissions:
Note: Depending on the Player Settings and Unity APIs that the application uses, Unity automatically adds some required permissions to the Unity Library Manifest. For more information, see Unity-handled permissions.
Unity uses templates to produce the final Gradle project files. You can override the template that Unity uses and new permissions for an application via the template.
For more information, refer to Modify Gradle project files with Gradle template files.
The Android Project Configuration Manager represents Gradle project files in C#. You can use the API to add new permissions for an application.
For more information, refer to Modify Gradle project files with Android Project Configuration Manager.
To have complete control over which permissions are in the final Android App Manifest file, export the project and edit the Android App Manifest in Android Studio.
For more information, refer to Modify Gradle project files with Android Studio.
