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 cameraView.start() once they are acquired
• or call cameraView.start() anyway: CameraView will present a permission request to the user based on whether they are needed or not with the current configuration.

In the second case, you should restart the camera if you have a successful response from onRequestPermissionResults().
