I don't want to analyze all libraries ;) just the program. So there is 
no way to create an intraprocedural cfg and go through it with Soot? 
With the intra cfg i can construct an inter cfg, i think.

I want to analyze Android programs. It's a kind of SOA. So there are 
methods for start, stop, pause, resume an activity (window/program) and 
the user interaction works with adapters. Then there could be several 
methods which receives messages and do something with it. So there are 
many entry points i've to analyze...
