Android: consulta sql a CONTENT_URI

Hello every androids developers! Please would you help with one question. I am trying

Cursor cursor = getContentResolver().query(Contacts.CONTENT_URI,CONTACT_PROJECTION, n" _id = _id ) GROUP BY ("+ Calls.NUMBER, null, "cnt DESC");

and it is work fine in Android 2.3.3, but at the Android 4.03 it is crashed because Android 4.03 do not support anymore GROUP BY queries. ( https://stackoverflow.com/questions/8837544/android-ics-sqlite-error )

So i decide to form raw sql query to URI Contacts.CONTENT_URI with example code

ContentProviderClient client =  getContentResolver().acquireContentProviderClient(AUTHORITY);
SQLiteDatabase dbHandle= ((MyContentProvider)client.getLocalContentProvider()).getDbHandle();                    
Cursor cursor = dbHandle.rawQuery("SELECT _id, date, duration, number, type, name,   numbertype, COUNT(*) as cnt FROM calls WHERE ( 1=1 ) GROUP BY (number) ORDER BY cnt DESC", null);

o con

SQLiteQueryBuilder qb = new SQLiteQueryBuilder();
qb.query(db, projectionIn, selection, selectionArgs, groupBy, having, sortOrder)

that have groupBy parameter.

But i do not understood how to get dbHandle from CONTENT_URI or db name of CONTENT_URI in second case.

Gracias de antemano!
