Obfuscation paused in between #87

Closed ArchanaNair closed 10 months ago

ArchanaNair commented 3 years ago

Hi,

I am trying to run a basic command like below, but obfuscation paused in between, what could be the error here?

python3.7 -m obfuscapk.cli -p -d /.../obfuscated.apk -o Rebuild -o NewSignature -o NewAlignment /.../app-dev-release.apk

Running obfuscators (NewSignature): 33%|█████████████▋ |[00:31<01:02, 31.09s/obfuscator]

Hi, try enabling the verbose logging to better understand what's going on. If the obfuscation is stuck on NewSignature maybe there is some problem with the underlying apksigner.

@ClaudiuGeorgiu , thanks for the quick response. I have enabled log, As you said it got stuck in newsignature.

I have set the path of apksigner as below in MAC OS, environment variable.

export APKSIGNER_PATH=/../Library/Android/sdk/build-tools/29.0.3/apksigner
export ZIPALIGN_PATH=/../Library/Android/sdk/build-tools/29.0.3/zipalign export APKTOOL_PATH=/usr/local/Cellar/apktool/2.5.0/bin/apktool

I am not sure what causing apksigner issue? Please advise

I am using comment like below

python3.7 -m obfuscapk.cli -o ConstStringEncryption -o Goto -o Rebuild -o NewSignature -o NewAlignment -p /Users/.../app-dev-release.apk --keystore-file /Users/.../key/xxxkeystore --[keystore-password storepwd] [--key-alias alias] [--key-password keypass]

O/P: Without any error, it is executing. But when I am trying to install obfuscated apk on my Device, It gives me an error that "App Not Installed". Is there any chance of apk got corrupted?,

Encrypting constant strings: 100%|██████████████████████████████████|[00:11<00:00, 634.70file/s] Inserting "goto" instructions in smali files: 100%|████████████████|[00:05<00:00, 1278.08file/s] Running obfuscators (NewAlignment): 100%|██████████████████████|[00:49<00:00, 9.91s/obfuscator]

I read in FAQ that, if app uses any anti-tampering technique or any sort of encryption, the application may not install My app uses androidx.security.crypto.EncryptedSharedPreferences and I have enabled the Proguard (shrink resource/ minify enables as true) also it is published via Intune( plugins are added in build.gradle) If this what causing an issue, how can I resolve it , Please help. I tried --ignore libs, but that doesn't seem working

I ran below basic command, which is executed without any error but app can't be installed python3.7 -m obfuscapk.cli -o Rebuild -o NewSignature -o NewAlignment
