[Soot-list] Issues with Android Instrumentation Tutorial

[kuza55]

Well, I worked this out in the end.

When using -cp, it seems to override the -android-jars parameter, so I
need to provide the specific android jar on the class path.
This seems like a bug.

When I use setSootClassPath, it seems to also remove the apk from the classpath.

It would be nice if there was an API that added to the classpath
without messing with the other options.

In the end I set -cp
"C:\\Users\\Alex\\Development\\analyzer\\lib\\android-platforms\\android-17\\android.jar;C:\\Program
Files\\Java\\jdk1.8.0_91\\jre\\lib\\rt.jar" and it didn't complain.
