Hey there,
I've been trying to get your script found here to work, namely this bit:
$ frida --codeshare LAripping/trace-registernatives -f com.app ... [Device::com.app]-> nativeMethods
I have attempted running it from codeshare, with auto-reload on, and specifying pause, as well as copying the script locally and trying the native libraries bundled with the app. None seem to work.
The script does appear to load as when nativeMethods is printed it returns an empty object.
Any ideas why this might be happening? I suspect it is because I'm on Frida 16.0.2 and there might be some breaking changes (in which case the tutorial will need to be updated)
