The command I am using: bash instrument.sh autoTracer/test/app-debug.apk output /Users/Pezh/Library/Android/sdk/platforms where:

Ouuups... something went wrong! Sorry about that.
Follow these steps to fix the problem:
1.) Are you sure you used the right command line?

Could you set a conditional breakpoint (for clazz == null) at line 139 of OverrideAllMethods.java and give me the runtime value of the variable "superclass" by traversing up the stack in the debugger until you get to line 33 of OverrideAllMethods.java?

This looks like soot is loading in a malformed class hierarchy. The class in "superclass" on the above mentioned line will show where it is coming from. The solution will probably be to remove a malformed Android jar from your SDK directory or recompile the instrumentation code.

Another thing to look at is see if it is resolving the correct Java runtime library. It may not be pulling in the "java.lang.Object" class.

@Pezhin can you let me know if this is fixed?

Pezhin commented 7 years ago

@ftc: Sorry I haven't got a chance to do this recently, Let me try it on weekends and get back to you later

Pezhin commented 7 years ago

This is the superclass value img

This lineif(clazz.getName != "java.lang.Object") the value of clazz is "java.lang.Object" -> "java.lang.Object" -> "android.app.Fragment" -> "null"

@Pezhin if you are still needing to use this I have fixed the issue on the develop branch.
