How to represent an array in JavaScript when hooking Dalvik methods about frida-gum HOT 4 CLOSED

Hi,

I don't think we handle this currently. If you feel like diving into the code and having a stab at implementing it, I would suggest copy-pasting the contents of “gumscript-runtime-dalvik.js” into a .js file that you load into a test app like this: frida -R -l foo.js com.android.browser, and just rename the one ObjC reference to something else and then add some test code at the bottom of the script that you use to test your changes. You may then edit the implementation and in the REPL just do %reload to try the new version quickly. Once you're happy with it just copy-paste it back into frida-gum, commit and submit a PR.

Cheers!

The code is here: https://github.com/frida/frida-gum/blob/master/bindings/gumjs/gumscript-runtime-dalvik.js

For String[] it works already.
Try

 hook.hookMeArray.overload("[Ljava.lang.String;").implementation = {...};

Thanks @marc1006; assuming this is fixed.
