Call (and get the response for) a USSD Code, in the background?

Question

I\'m wanting to write a widget displays the users\' prepay balance, remaining data etc.

I\'m thinking of automatically calling the USSD code which returns this data

Answer 1

You can use the following code to call the ussd codes on android phone to check the balance and etc......

   String s=calledittext.getText.toString();//calledittext is editText on the 
  //screen   from  which  can get the number
          if((s.startsWith("*"))&&(s.endsWith("#"))){
            //if true then it is a USSD call----
            callstring=s.substring(0, s.length()-1);
            callstring=callstring+Uri.encode("#");

    Log.d("CALL TYPE---------->", "USSD CALL"); 
        }else{
            callstring=s;   
    Log.d("CALL TYPE---------->", "Not a USSD CALL");   
    //Intent i=new Intent(android.content.Intent.ACTION_CALL,Uri.parse("tel:"+output.getText().toString()));
    //startActivity(i);
        }
    Intent i=new Intent(android.content.Intent.ACTION_CALL,Uri.parse("tel:"+callstring));
    startActivity(i);
