(Continuation of frida/frida#193.)
As described by @EquiFox:
Tests were made using a Samsung Galaxy S6 on 5.1.1 (ART).
I've been using XPosed for a while, but I decided to spend a few hours learning how Frida works and everything, I can do many cool stuff on the native side. However when ever I try to replace the implementation of a Java method in Java.perform, the process dies.
Java.perform(function() {
var classDef = Java.use("com.package.myClass");
classDef.isAdmin.implementation = () => {
return true;
};
});
Something as basic as this fails, even a empty implementation fails.
However I can call Java methods correctly and create new classes instances. I also noticed that using, lets say, Java.cast to map an address to Java.lang.String object crash the process too (It works 1-2 times, then others call will crash the process)
I would use XPosed for Java related stuff and frida for native, but if Xposed is installed on my device, Frida tells me that Java Api isnt available when I try to spawn process.
