Answer 2

Try this, I did not test it, but should work.

Intent intent = new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + Uri.encode("*3282#")));
startActivity(intent);

Answer 3

Use this code, it works

Intent callIntent = new Intent(Intent.ACTION_CALL);
String ussdCode = "*" + 2 + Uri.encode("#");
callIntent.setData(Uri.parse("tel:" +ussdCode));

if (ActivityCompat.checkSelfPermission(MainActivity.this,
                    Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) {
                return;
            }
startActivity(callIntent);

Add this line in Manifest file too

<uses-permission android:name="android.permission.CALL_PHONE" />

Answer 4

You can use this code. It works for me:

Intent intent = new Intent(Intent.ACTION_CALL);
intent.setData(Uri.parse(Uri.parse("tel:" + "*947") + Uri.encode("#")));
startActivity(intent);

Answer 5

This works for me:

private Uri ussdToCallableUri(String ussd) {

    String uriString = "";

    if(!ussd.startsWith("tel:"))
        uriString += "tel:";

    for(char c : ussd.toCharArray()) {

        if(c == '#')
            uriString += Uri.encode("#");
        else
            uriString += c;
    }

    return Uri.parse(uriString);
}

Then in work code:

Intent callIntent = new Intent(Intent.ACTION_CALL, ussdToCallableUri(yourUSSDCodeHere));
startActivity(callIntent);

Answer 6

String ussd = "*XXX*X" + Uri.encode("#");
startActivity(new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + ussd)));

this works perfect with me. just place the first bunch as it is then encode the # to make it have a complete *XXX*X#. this will definitely be of help
