Long back, android used to have GtalkService that let applications use Gtalk for various purposes, it was removed due to security reasons. Do we still have a method of invoking a Gtalk service that let us interact with gtalk from another application e.g. pinging a friend programmatically.
GTalk is nothing else as a Google XMPP Service. So you have 2 options for android:
- Use Asmack, a ported Smack Library for Android
or
- Use AsmackService (not yet releases but functional), together with AsmackLibrary.
You may want to check sources of TalkMyPhone application. Don't know if its using GtalkService, but it does gtalk interaction, works nicely for me.
