android逆向奇技淫巧二：uiautomatorviewer&method profiling定位x音java层的关键代码和方法
做逆向，不论是在windows还是Android，抑或是macos，都必须要面对的一个问题：找到关键的代码。android平台下怎么找到关键的代码了？本文以某国民级短视频APP为例，分享从UI界面定位到关键代码的链路逻辑！
1、老规矩，先在模拟器运行这款APP，然后打开ui automator viewer “截屏”（注意：要暂停短视频播放才行，否则截屏的时候会报错）！如下：
比如我们想找点赞按钮的执行代码（至于为什么要找这个按钮的执行代码，道上人士都懂的），光标移动到笔芯上，右边就会显示出笔芯的imageView，这里能看出其实是一个按钮控件；先阿敏有resource-id和class类型；接着进入jadx（这种apk上百兆，用jadx容易卡死，需要增加内存，增加的方法见文章末尾的参考1），找到resources.arsc文件，用刚才找到的id字段也就是byb作为关键词，找到点赞笔芯的id: 2131168834
然后继续搜索，发现原来是这两行代码引用了：
本想点击进一步查看java源码，无奈本机内存只有16G，而jadx已经消耗了9G，还是卡者不动，无法继续，这里换成android killer继续逆向分析。把这一串id转成16进制，然后在android killer里面搜索：
发现到处都在引用；后续会继续分享怎么分析这些引用！
至于这里为啥用id来检索，而不是控件的名称了？我个人理解：大概率是因为控件名称开发人员随时都可能更改，所以编译器自动生成id与之对应。控件名称随时可以改，但是id不变，通过这种方式做到松耦合！
2、上面使用了这个id的地方还是有很多，挨个去静态分析还是耗时，怎么能快速找到点赞执行了哪些代码了？这里有个更快速的方法：method profiling；本质上，method profiling相当于录屏，结果如下: 因为用户需要手动点击笔芯才能点赞，所以肯定会调用onclick方法，这里就能根据onclick作为关键词查询：
只有这两个地方调用了onclick方法：
接下来再去jadx或android killer找这两个方法分析源码，是不是简单多了？（用AK搜的时候注意把.改成/）
老规矩，最后整理一下常见的静态分析方法：
注意：x音没登陆时点击屏幕用的是onClick来监听的；一旦登陆，用户点赞用的就是onTouch监听了，method profiling捕获到的函数调用如下：
代码在这：
public boolean onTouchEvent(MotionEvent motionEvent) { View.OnTouchListener onTouchListener; boolean z = false; PatchProxyResult proxy = PatchProxy.proxy(new Object[]{motionEvent}, this, f173585a, false, 254253); if (proxy.isSupported) { return ((Boolean) proxy.result).booleanValue(); } if (!isEnabled()) { return false; } this.j = true; int actionMasked = motionEvent.getActionMasked(); if (actionMasked != 0) { if (actionMasked != 1) { if (actionMasked == 2) { this.n = motionEvent.getX(); this.o = motionEvent.getY(); float abs = Math.abs(this.f173586b - this.n); float abs2 = Math.abs(this.f173587c - this.o); int i2 = this.p; if (abs > ((float) i2) || abs2 > ((float) i2)) { z = true; } if (z) { com.ss.android.a.a.a.a.c(this.s); } View.OnTouchListener onTouchListener2 = this.r; if (onTouchListener2 != null) { onTouchListener2.onTouch(this, motionEvent); } } else if (actionMasked != 3) { if (actionMasked == 5) { com.ss.android.a.a.a.a.c(this.s); } } } com.ss.android.a.a.a.a.c(this.s); if (SystemClock.elapsedRealtime() - this.f173591g < ((long) this.q) && (onTouchListener = this.r) != null) { onTouchListener.onTouch(this, motionEvent); } } else { this.f173586b = motionEvent.getX(); this.f173587c = motionEvent.getY(); this.f173591g = SystemClock.elapsedRealtime(); com.ss.android.a.a.a.a.a(this.s, this.q); View.OnTouchListener onTouchListener3 = this.r; if (onTouchListener3 != null) { onTouchListener3.onTouch(this, motionEvent); } } super.onTouchEvent(motionEvent); return true; }
这个和上面那个是父子关系：
继续一层一层往下拨：
继续往下拨：
反编译失败了：
直接看smali代码或hook看看传入的参数是啥：
直到这里进入系统函数才罢休：
这里貌似是遍历短视频，如果还有就取出来对比id，看看是不是同一个短视频：
两个参数都是float，看着像横纵坐标：
仅通过静态分析也看不出啥花样来，这里继续用objection去hook上述提到的一些关键方法，看看传入的参数和返回值都是啥了：
objection --gadget "com.ss.android.ugc.aweme" explore android hooking watch class_method com.ss.android.ugc.aweme.feed.utils.m$1.onTouch --dump-args --dump-backtrace --dump-return android hooking watch class_method com.ss.android.ugc.aweme.feed.panel.b$10.a --dump-args --dump-backtrace --dump-return android hooking watch class_method com.ss.android.ugc.aweme.feed.panel.t.a --dump-args --dump-backtrace --dump-return android hooking watch class_method com.ss.android.ugc.aweme.feed.panel.b.a --dump-args --dump-backtrace --dump-return android hooking watch class_method com.ss.android.ugc.aweme.feed.story.viewmodel.b$a.a --dump-args --dump-backtrace --dump-return android hooking watch class_method com.ss.android.ugc.aweme.common.widget.DiggLayout.a --dump-args --dump-backtrace --dump-return
一次性hook了这么多函数，信息量最大的就是下面这个函数了，参数传入了一大堆，但和用fiddler抓的数据相差甚远，所以有两种可能：（1）java层发送数据的不是这些函数，这里没hook到 （2）发数据的函数在so层；
