Cursor cursor = db.rawQuery("SELECT COUNT(rat) 
                               FROM "+ TABLE_NAME_EXTRA +" apkid=\""+apkid, null);
cursor.moveToFirst();
int somatotal = cursor.getInt(0);

I'm trying to do a SQL function like count and sum, but this code returns a exception saying "emptyvalues".

anyone know why?
