UpAndroid WebView OnTouchListner throwing Exception

Question

I have the below code which using WebView's OnTouchListner,

            wvmmsgoftheday.setOnTouchListener(new OnTouchListener() {

                @SuppressLint("ClickableViewAccessibility")
                @Override
                public boolean onTouch(View v, MotionEvent event) {             
                    if(event.getAction() == MotionEvent.ACTION_DOWN){
                        handler.sendEmptyMessageDelayed(CLICK_ON_WEBVIEW, 500);
                        return true;
                    }

                    return false;
                }
            });

This code works perfect in my Android Mobile version 4.1.0, but I execute the same code Samsung Galaxy Tab Android version 4.0.1 getting Null Pointer Exception.

Can someone help to know what is the reason? OnTouchListner Event have any depending Android version?

Paste the logcat (full stack trace). The problem is after click? — krystian71115, Jul 20 '15 at 10:59

Maybe you have a different layout in layout-large or layout-xlarge. The phone do not search this directories. — krystian71115, Jul 20 '15 at 12:16
