1.搜索“成功”
这里搜索到了三条数据
点进去之后是这样一个方法：

这里找到一个调用成功的方法。我们继续溯源查看。
发现是一个onResult方法。
解决方法：
（1）覆盖switch失败转为成功。
（2）更改switch跳转
（3）最后一种我最喜欢作用，思路最明确，使用goto进行跳转。跳转到成功即可。
恩，改完之后汇编，整个游戏就破解好了。
没什么好说的。
是成功的，懒的玩。不想发图，自己测试吧，有疑问可以找我。
之前没有找好，现在去找找。
找练习的APK的时候主要注意三点。
（1）最好是单机
（2）选择大小的时候选小一点的，恩，反编译快。我们的目的是为了练习。
（3）无壳，现阶段可定脱不了壳。
找到了一个什么酷跑什么的游戏。
三步走
原版apk：练习传送门在这里找，编号：2002
拿到游戏，首先就要玩一下是不，人家怎么购买的你总要知道吧。说不定会有新的发现。
搜索关键字“成功失败”
点开之后进去，发现，原来还是一个onResult。
