Answer 1

String selection = MySQLiteHelper.STATE + " = 'Maharashtra'"  
            +" AND " + MySQLiteHelper.CITY + " = 'Thane'"
            +" AND " + MySQLiteHelper.REGION + " = 'Checknaka'";

    Cursor cursor = database.query(MySQLiteHelper.RETAILER_TABLE, 
                new String[] {MySQLiteHelper.COLUMN_ID, MySQLiteHelper.SHOP }, selection, 
                null, null, null, null);

May be the reason is that, you are refering to Strings without ''
