Hi all,
I resolved the issue and finally i am getting the call graph. Thank you all
of you for your time and help. :)
1. But Stevan I am still curious to know how to work with QueueReader
Object for generating dot format.
2. And why the size of call graph for RV2013.apk is 54. And is there any
way to remove unnecessary size.
Thanks&Regards
Lokesh
