I\'m using an intent to open the camera with the native application:
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
Uri photoUri = Uri
Word of caution: its a hack
Add this to the intent
intent.putExtra("android.intent.extras.CAMERA_FACING", 1);
This solution isn't sustainable, its using a testing code of the Camera app. For more info look at the "getCameraFacingIntentExtras" static method in Util class of the AOSP Camera project.
Update: Looks like that it was disabled in L
