Do not change class name of service

Hi! Do not change java class name of service when using native code (jni)?

Program just exits

i give the apk as the argument. The program just exits. It happens when i dont give any argument to it.

python obfuscators/obfuscators.py just exits.

How Does classes.dex Get Updated

I have this code running - and I set my list of obfuscation tasks - and it runs. I am doing Reflection, Reordering, Renaming, and Indirection. So, some fairly sizable changes to the bytecode.

When it completes it goes, signs the jar file, and I have a new APK. But ... when I open up the APK the classes.dex file is the same size as the original. When I open and view both dex in a tool like JADX they are identical.

Am I missing something? Should not classes.dex be different? If so, why would it not update the file w/in the APK.

Very frustrating :(

jarsigner: unable to open jar file

I am able to execute the code but the output files are not in correct format. I'm getting the following error: jarsigner: unable to open jar file
I think the error is due to the code:
popen('jarsigner -sigalg MD5withRSA -digestalg SHA1 -keystore ' + obfuscator_resource_dir + '/resignKey.keystore -storepass resignKey ' + sample_file_name + ' resignKey')

Also, do I need to update any packages/dependencies for SHA256 instead of SHA1?

Thanks

String Encryption and Renaming dont seem to work

I have the code running and I am testing it to evaluate the quality of obfuscation produced.
Currently as a first attempt i tried using the list of ['Fields', 'Renaming', 'StringEncrypt', 'Manifest']. The resulting obfuscators.log reports success but upon analysis of the output apk all the methods and classes have their original names. I am suspecting I am doing something wrong!

SECOND ATTEMPT
This time i tried to run ['Manifest', 'Renaming'] only, and to my surprise the output was indeed obfuscated, the names of the methods and classes are random this time. I tried to run this apk but no matter if i run in on emulator or not the result is that it keeps crashing with a message from Android Name_of_the_app keeps stopping.

THIRD ATTEMPT
Using only ['Renaming'], nothing happens again, like the first attempt

P.S The paths are wrong in the obfuscators/obfuscators.py and i have fixed them in order for this to work -- plus i have made the appropriate changes in smali and backsmali to work with apktool 2.4.0
