[Soot-list] Generating Android APK CallFlowGraph

[Eric Hoang]

Hi Steve and Lokesh,

My name is Eric, I am a newbie with Soot framework and FlowDroid. I found 
this conversations that you had solved the problem generate dot graph for 
APK. I follow your old code and receive error: 
DotGraph.getNode(DotGraph.java:56)
DotGraph.drawNode(DotGraph.java:65)

So, how did you solve this problem? May you share the final code of 
CFG.java and DotGraph.java for me?

Looking forward for your reply.

Thanks and regards,
Eric
