//get ContentResolver instance

ContentResolver crInstance = getContentResolver(); Cursor c = crInstance.query(CONTENT_URI, null, null, null, null); startManagingCursor(c); StringBuilder sb = new StringBuilder(); if(c.moveToFirst()){ do{

sb.append(c.getString(1)).append("\n"); }while(c.moveToNext());
