CameraView needs two permissions:

• android.permission.CAMERA : required for capturing pictures and videos
• android.permission.RECORD_AUDIO : required for capturing videos with Audio.ON (the default)

Declaration

The library manifest file declares the android.permission.CAMERA permission, but not the audio one. This means that:

• If you wish to record videos with Audio.ON (the default), you should also add android.permission.RECORD_AUDIO to required permissions

<uses-permission android:name="android.permission.RECORD_AUDIO"/>

• If you want your app to be installed only on devices that have a camera, you should add:

<uses-feature
    android:name="android.hardware.camera"
    android:required="true"/>

If you don't request this feature, you can use CameraUtils.hasCameras() to detect if current device has cameras, and then start the camera view.

Handling

On Marshmallow+, the user must explicitly approve our permissions. You can

• handle permissions yourself and then call open() or setLifecycleOwner() once they are acquired
• ignore this: CameraView will present a permission request to the user based on whether they are needed or not with the current configuration.

Note however, that this is done at the activity level, so the permission request callback onRequestPermissionResults() will be invoked on the parent activity, not the fragment.
