AndroidMethodHook
结合阿里Sophix热修复方案(https://yq.aliyun.com/articles/74598?t=t1#)
使用了dexmaker库，主要用来动态生成dex文件。
使用方法：
```Java
HookManager.findAndHookMethod(MainActivity.class, "onCreate", Bundle.class, new MethodCallback() {
@Override
protected void beforeHookedMethod(MethodHookParam param) throws Throwable {
super.beforeHookedMethod(param);
Log.d("panda", "onCreate:"+param.thisObject.getClass().getName());
}
@Override
protected void afterHookedMethod(MethodHookParam param) throws Throwable {
super.afterHookedMethod(param);
Log.d("panda", "i'm in method " +param.method.getName()+" afterHookedMethod");
}
}); HookManager.startHooks(base);
通过对Native JmethodId内容替换实现method hook，为了达到类似于xposed的效果，需要动态生成method，使用了dexmaker库用以动态生成mehtod。Java package com.panda.hook.andhook;
每个需要hook的方法都会dexmaker生成一个一摸一样的方法，将this和传入参数封装成Object[] args传给MethodUtil类的invoke函数，然后回调MethodCallback实现类似于xposed mehtod hook。
生成代理method方式如下：
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public double test(Object thiz,int a,int b,char cr){
return (a+0.0)/b;
}
}
Java public class compandahookandhookMainActivity { public compandahookandhookMainActivity() { super(); }public double test(Object arg12, int arg13, int arg14, char arg15) { return MethodUtil.invoke("compandahookandhookMainActivity_testLIICD", this, new Object[]{ arg12, Integer.valueOf(arg13), Integer.valueOf(arg14), Character.valueOf(arg15)}).doubleValue(); } } ```
