Christian,
Sounds like your interested in malware. Something I am interested in as well. That being said I am not sure this is the best forum for this discussion. There are numerous ways to do 'covert' exfiltration on Android. The easiest, and what most Malware developers do, is just ask for permission for a service to do something in the back ground, like send SMS, or connect to the internet. If you look at malware currently in the App Market this is the most common mechanism. There are other ways and if you are interested I suggest you join one of the many digital security professional mailing lists or forums where researchers discuss these sorts of things in detail.
Cheers,
Robi
