Find the solution

Overide the below method

long lastActivity ;
@Override
public boolean dispatchTouchEvent(MotionEvent ev) {
    lastActivity = new Date().getTime();
    return super.dispatchTouchEvent(ev);
}

In onResume()

@Override
public void onResume() {
    long now = new Date().getTime();
    if ((now - lastActivity) > Your logout  Value) {
       // do your implementation
    }
}
