Remarks

Unlocks the camera to allow another process to access it. Normally, the camera is locked to the process with an active Camera object until #release() is called. To allow rapid handoff between processes, you can call this method to release the camera temporarily for another process to use; once the other process is done you can call #reconnect() to reclaim the camera.

This must be done before calling android.media.MediaRecorder#setCamera(Camera). This cannot be called after recording starts.

If you are not recording video, you probably do not need this method.
