here the code creates the DrinkID and order. It then sends this list of numbers to the arduino.

order.java

//FINAL ORDER BUTTON (POPUP, SENDS DRINK ARRAY TO ARDUINO)
    //------------------------------------------------
    public void onClickOrder(View view) {

        //The Functions bellow are converting intiger values into strings which can then be written to the arduino via a Serial Connection
        String VodkaOrder = Integer.toString(Vodka_Measure);
        String RumOrder = Integer.toString(Rum_Measure);
        String GinOrder = Integer.toString(Gin_Measure);
        String WhiskeyOrder = Integer.toString(Whiskey_Measure);
        String TonicWaterOrder = Integer.toString(TonicWater_Measure);
        String CranberryJuiceOrder = Integer.toString(CranberryJuice_Measure);
        String OrangeJuiceOrder = Integer.toString(OrangeJuice_Measure);
        String PineappleJuiceOrder = Integer.toString(Pineapple_Measure);
        String MintOrder = Integer.toString(Mint_Measure);
        String SugarOrder = Integer.toString(Sugar_Measure);
        String LimeJuiceOrder = Integer.toString(Lime_Measure);
        String LimeSliceOrder = Integer.toString(Lime_Slice);
        String StirOrder = Integer.toString(Stir);
        String MashOrder = Integer.toString(Mash);
        String ShakeOrder = Integer.toString(Shake);
        String IceOrder = Integer.toString(Ice_Measure);
        String KaluaOrder = Integer.toString(Kalua);
        String CointreauOrder = Integer.toString(Cointreau);
        String VermouthOrder = Integer.toString(Vermouth);
        String PeachSchnappsOrder = Integer.toString(Peach_Schnapps);
        String CreamDeCacoOrder = Integer.toString(Cream_De_Cacao);
        String DrinkSizeOrder = Integer.toString(DrinkSize);

        //Actually writing the data to the arduino using the new strings created above
        serialPort.write(VodkaOrder.getBytes());
        serialPort.write(RumOrder.getBytes());
        serialPort.write(GinOrder.getBytes());

        serialPort.write(DrinkSizeOrder.getBytes());

        //A small text so the user knows what he/she ordered!

        tvAppend(textView, "\nYour Drink Order is one " + DrinkSizeText + " " + DrinkName + " (" + DrinkType + ")" + "\n");




                myDialog.dismiss(); //Closes the popup after the order button is pressed, and order data is sent
