关于Unity自动为安卓添加权限

某些代码会使Unity自动添加安卓权限
https://docs.unity3d.com/Manual/android-manifest.html

Unity automatically adds the necessary permissions to the Manifest based on the Player Settings and
Unity APIs that your app calls from the script. For example:

Network classes
add the INTERNET permission

Using vibration (such as Handheld.Vibrate)
adds VIBRATE

The InternetReachability property
adds ACCESS_NETWORK_STATE

Location APIs (such as LocationService)
adds ACCESS_FINE_LOCATION

WebCamTexture APIs
add CAMERA permission

The Microphone class
adds RECORD_AUDIO

参考：

ACCESS_FINE_LOCATION permission can come from:
- Input.location API calls https://docs.unity3d.com/ScriptReference/Input-location.html
- your plugins having the permission in the manifest or calling this API.
