feat: Added Support for Managed Method Hooking #6

Closed alxbl closed 4 years ago

alxbl commented 4 years ago

First off, I wanted to say this is a really cool project! It's been very helpful to get started doing Xamarin research with Frida on Android! Thanks for sharing!

This pull request adds several export signatures to the raw API, but most importantly, it adds initial support for hooking managed methods. This is exposed in the form of a MonoApiHelper.Intercept function with the following signature: Intercept(klass: ClassMetadata*, methodName: string, callbacks: {onEnter, onLeave}).

The onEnter and onLeave callbacks work identically to the Frida Interceptor API.

I'm open for any feedback, and I hope this will be useful.

Cheers, Alex
