Android : How to remove duplicate from CallLog?
===

    mCursor = getContentResolver().query(
				CallLog.Calls.CONTENT_URI,
                new String []{ "max(date) as max_date", "name", "date","type", "number" },
                " 1=1) group by(number ", null,
				CallLog.Calls.DEFAULT_SORT_ORDER);
My query is wrong, 

no one has done a similar query,

 how to query the results did not repeat?

Thanks!
