Use above code in Activity as below :

public class MainActivity extends AppCompatActivity implements LogOutTimerUtil.LogOutListener
{
    @Override
    protected void onStart() {
        super.onStart();
        LogOutTimerUtil.startLogoutTimer(this, this);
        Log.e(TAG, "OnStart () &&& Starting timer");
    }

    @Override
    public void onUserInteraction() {
        super.onUserInteraction();
        LogOutTimerUtil.startLogoutTimer(this, this);
        Log.e(TAG, "User interacting with screen");
    }


    @Override
    protected void onPause() {
        super.onPause();
        Log.e(TAG, "onPause()");
    }

    @Override
    protected void onResume() {
        super.onResume();

        Log.e(TAG, "onResume()");
    }

    /**
     * Performing idle time logout
     */
    @Override
    public void doLogout() {
      // write your stuff here
    }
}
