Got Answer from Abhay Koradiya,

issue was onTouchEvent that not called if pdfviewer attached => This hapen because pdfviewer already consumed touch event.

So you need to use

dispatchTouchEvent

instead of that. check here

@Override
public boolean dispatchTouchEvent(MotionEvent event) {
    gestureDetector.onTouchEvent(event);
    return super.dispatchTouchEvent(event);
}
