Answer:

The Camera class may solve your question. Execute getCameraInfo to get the information and then useCameraInfo. It has two constants:

int CAMERA_FACING_BACK The facing of the camera is opposite to that of the screen.
int CAMERA_FACING_FRONT The facing of the camera is the same as that of the screen.
