  • ReferenceError: breakpoint is not defined

    ReferenceError: breakpoint is not defined

    I am getting the error in the title when breakpoint() is executed. Here is how the command: Interceptor.attach(Module.findBaseAddress("libhello-jni.so").add(0x1161),function(arg) {console.log("hit");breakpoint()});

    Also, I am getting the same error as #88 when I run api.nativeBacktrace(); So I followed all the instructions there:

    • frida & frida server changed to 12.x
    • "disable_local_frida_update":true to prevent autoupdate
    • self._script = self._process.create_script(script_content, runtime='v8')
    • also made sure that "memPtr = ptr(address);" is fixed as per the patch in core.js
    • attached apk and source code (example hello-jni with a button to re-run the lib, apk located in hello3\app\debug\app-debug.apk) hello3.zip

    image

    The above command works for armv7 only, the following command should work on any arch: Interceptor.attach(Module.findExportByName("libhello-jni.so","getStr"),function(arg) {console.log("hit");breakpoint()});
