How to display recent call list when we click on home screen?

Question

Hi all, I am new to android. I am developing an application in which I want to show recent call list (missed, incoming and outgoing) when user touch on home screen.

I can get recent call list by below code:

String[] strFields = {
        android.provider.CallLog.Calls.NUMBER, 
        android.provider.CallLog.Calls.TYPE,
        android.provider.CallLog.Calls.CACHED_NAME,
        };
String strOrder = android.provider.CallLog.Calls.DATE + " DESC"; 

Cursor mCallCursor = getContentResolver().query(
        android.provider.CallLog.Calls.CONTENT_URI,
        strFields,
        null,
        null,
        strOrder
        );

How and where to set onTouchListener?

Your help means a lot to me.

Thanks, Ketan
