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, refer to 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, refer to Unity-handled permissions.
The simplest way to add new permissions for an application is to create a template Unity Library Manifest file and add the permissions to it.
For more information, refer to Create a template Unity Library Manifest file.
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 Edit the Android App Manifest in Android Studio.
