USSDNetworkService used to replace Android default one and get USSD messages results.

This probably won't work if another application already use it. Also it my not work on some versions of Android. I've tested it on Android 2.1-2.3, 4.1. Also I've founded out that it not work on some sony mobile phone(don't remember model), so I think it may not work on some devices according to modified firmwares.

I also do many research about USSD, but i can't get the response and how to close ussd result dialog, like this application done: https://play.google.com/store/apps/details?id=com.iba.ussdchecker&hl=en.

could you give me an real example, please

What about manifest? How can I use this service?

How about reading USSD response in 4.2.2?

Does this work in latest android versions like 4.0+ ?

This method seems to be working on versions of android up to 4.2.1 as I've heard the interface IExtendedNetworkService has been removed from the SDK since then (due to security reasons). Though is there anybody knows how to make original dialer dialog invisible ?

@umeshongithub: it not working on android 5.1.1, can you upgrade code ?

This would only be possible in an Android version earlier than 4.2.2. In 4.2.2 the IExtendedNetworkService seems to have been removed by Google due to security risk. See issue posted at Google – https://code.google.com/p/android/issues/detail?id=57120
