how to detect incoming Skype/Viber call

Question

I am developing a music app and for that I need to detect incoming calls (Phone, Skype, Viber etc) in order to stop the playing song. I can detect GSM calls using PhoneState listener. Is there any way to detect data/VoIP (Skype, Viber) calls?

You shouldn't need to detect anything so specific, but rather manage audio focus correctly. Please see this guide on how to do that: https://developer.android.com/training/managing-audio/audio-focus.html
