Have you solved this problem? I encounter it too, and r2 cashed.

The current implementation of breakpoints is an event holder, which is not exactly how breakpoints should work, so its known and expected to fail. Eventually i'll find time to implement that properly, but ideally that should be a feature provided by frida-gum.

Afaik, the DWARF project (qt frontend for frida) implements breakpoints in a better way, if you try it out, let me know if it works well there and we can port that functionality without depending on changes in Frida.

I've tried DWARF's breakpoint function and it works well.

When discussing breakpoints. What is the state or considerations to being able to support smali breakpoints aswell? There are debugger like jadx, who support it. They use adb. As far as i know with apk:// r2 is able to display the dex code or smali quite well.

My plan is to implement the logic done in DWARF inside r2frida, and their implementation supports objc, native and dalvik breakpoints. That stuff is implemented in here https://github.com/iGio90/DwarfCore

hope to allocate some time for this next week, as long as i think it's a very important feature :)

Expecting it. Thanks

Please try the new breakpoint support now and verify whether it works or not :)
