How to execute USSD?

[Pablo J. Rogina]

@Blaster if by USSD you mean Unstructured Supplementary Service Data, I guess you may want to get some library that provides or helps you implementing that functionality. Maybe this example is a good starting point.

I just want to run USSD codes compatible with GSM, for example *123#, from android

Hi,

Do you mean something like described here ?

[Blaster]

Yes, I'll try it and then I'll tell you if it worked for me. Thank you

@SGaist I am trying to adapt the code shown in the tutorial that you put, but there is no way to find how to encode the #

[SGaist]

Do you mean Uri.encode("#") doesn't do the job ?

[Blaster]

Does anyone know how to do these in Qt?

private void dailNumber(String code) {
    String ussdCode = "*" + code + Uri.encode("#");
    startActivity(new Intent("android.intent.action.CALL", Uri.parse("tel:" + ussdCode)));
}

I apologize for that, but now I'm learning

Take a look at the QtAndroidExtras module.

It allows you to interface easily with Java code.

Well, I have already implemented the function in a java class. But I can not find the way to call it ... the problem is with startActivity (intent) the function in java is:

public void dailNumber(String code) {
    String ussdCode = "*" + code + Uri.encode("#");
    startActivity(new Intent("android.intent.action.CALL", Uri.parse("tel:" + ussdCode)));
}

While the method with which we call it is:

void CallDirectly::runUSSD(QString code)
{
	QAndroidJniObject ussdCode  = QAndroidJniObject::fromString(code);
	QAndroidJniObject::callStaticObjectMethod("cu/myapp/javaclases",
												"dialNumber",
												"(Ljav/lang/String;)V",
												ussdCode.object<jstring>());
}

[SGaist]

What is exactly your problem ?

[Blaster]

@SGaist My problem is that I can not call the dialNumber method, it does not run. Is there something wrong with my code?
