Pull values from table and add it to a temp variable

This method is suppose to repeating until enough calories have been added to the meal plan. The getMeat method adds one value with the ftype = meat. It should then sum every value in the calorie column and set cals to that number. This should continue until cals > Calories.

int Calories = 800;

public void getMeat(String mTables, int cals) {
    SQLiteDatabase db = getReadableDatabase();
    Random r = new Random();
    int mRand = r.nextInt(31 - 21) + 21;
    db.execSQL("INSERT INTO " + mTables + " (fName, Calories, Protein, Carbs) SELECT fName, Calories, Protein, Carbs FROM Schedule WHERE ScheduleID = " + mRand );
    Cursor c = db.rawQuery("SELECT SUM(Calories) FROM " + mTables, null);
    c.moveToFirst();
    String Caltemp = c.getString(c.getColumnIndex("SUM(Calories)"));
    cals = Integer.parseInt(Caltemp);
}

public Cursor getMeal_1_day1() {
    SQLiteDatabase db = getReadableDatabase();
    SQLiteQueryBuilder qb = new SQLiteQueryBuilder();
    int cals = 0;
    String [] sqlProject = {"0 _id", "fName", "Calories", "Protein", "Carbs"};
    String sqlTables = "fstMeal_1";
    Cursor mCursor = db.rawQuery("SELECT * FROM " + sqlTables, null);
    if(mCursor.getCount() == 0) {
        while(cals < Calories) {
            getMeat(sqlTables, cals);
            //getFruit(sqlTables);
            //getVegetable(sqlTables);
            //getDairy(sqlTables);
            //getNut(sqlTables);
        }
    }
    else {}
    qb.setTables(sqlTables);
    Cursor c = qb.query(db, sqlProject, null, null,
            null, null, null);
    c.moveToFirst();
    return c;
}

The app continues to run until i get a message that the app is no longer responding so i assume that the c.getString is not working and the calories are not being read in, but im not sure as to why.
