how to hook "myFunction" with xposed?

Answer 1

Have you tried to simply adapt the available examples to your class and method?

XposedHelpers.findAndHookMethod("com.my.app.myClass", lpparam.classLoader, "myFunction", new XC_MethodHook() {
    @Override
    protected void beforeHookedMethod(MethodHookParam param) throws Throwable {
        XposedBridge.log("before myFunction()");
    }
    @Override
    protected void afterHookedMethod(MethodHookParam param) throws Throwable {
        XposedBridge.log("after myFunction()");
    }
);
