App crashing - Tracing. Press any key to quit...

[dipa96]

Hi, I have been experiencing problems with jnitrace. Meanwhile, thank you for developing this great tool 🥇

Workspace:

• macbook chip m2
• Android Studio AVD Emulator (API 26 to 29 tested)
• frida, frida-tools and frida-server 16.1.0
• jnitrace 3.3.1

Tested App: ViewerJNI from Google Drive Folder You can also find a PoC, youtube video, here

My scenario: run: jnitrace -l libnative-lib.so com.example.viewerjni and tools reply with: Tracing. Press any key to quit...

In the same time, app open and crash.

Logcat stacktrace info:

Looking closer, I found this issues in the repo: https://github.com/chame1eon/jnitrace-engine/issues/13 . Workaround in this case: jnitrace -m attach -l libnative-lib.so viewerjni , tool work fine now. Do we know if anyone has solved it without using the attach method?

Cheers :)

Having this same issue. Attach does seem to work somewhat, but fails to hook onto other functions etc. Is there any status or workarounds for this at the moment? thanks.
