How to fix 'class cannot extends multiple classes'

Question

public class user_attandence extends HiddenCameraActivity, AppCompatActivity implements ConnectionCallbacks,
    OnConnectionFailedListener,
    LocationListener

If `HiddenCameraActivity` already a child of `AppCompatActivity` then you should remove `AppCompatActivity` from `extends`. — ADM, Mar 26 '19 at 06:28

Java doesn't support it. Use interface instead of it.
