[Soot-list] Issues with Android Instrumentation Tutorial

[Steven Arzt]

Hi Alex,

This behavior is debatable, but it's not a bug. The -android-jars parameter
is used to set the default classpath, i.e., the classpath that is used if
you do not explicitly specify one. We should maybe clarify this in the
documentation.

Best regards,
  Steven

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.
