I cant seem to call this class from Android app to send sms via the sms APi i have attached.

I have attached my call to the sender class to make a call to the http class when i want to send an SMS on button click. Button button; button = (Button) findViewById(R.id.noBtn); button.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) {

            //createUserAppointment();

            Sender sender = new Sender("xxxxxxxxxxxxx", 8080, "xxxxx",
                    "xxxx", "Congratulations! You just gave someone a priceless gift - LIFE! Thank you for donating." +
                    "Your next donation date is 13/6/16.", "1", "0", "xxxxxxxxx",
                    "Moja");
            sender.submitMessage();


        }


    });

Answer 1

And what produces your attempt? An error? Or it compiles well but does'nt do anything? Please share any output too

Well you put "xxxxxxxxx" in args because you don't want us to see the real adress or because you are just copy pasting the example?

Otherwise I'd suggest you to take a look here I am trying http connection over android
