android的Proguard混淆

这几天在混淆代码过程中遇到好几个坑，所幸堵了《app研发录》这本书，帮了我的大忙。

现记录先后遇到的几个坑：

1. butterknife，在混淆时注意是6.0还是7.0，混淆方式不一样；

2. 实体bean不要混淆，这会影响到JSON的使用；

3. 内部类尽量独立出来，无法独立单独的class，要标记不要混淆；

4. 友盟sdk，打包时一直提醒几千个警告，目前不知怎么解决

其他方面，下面这篇博客也有很大帮助：

Android Proguard原理

第三方库的混淆可以参考：

各框架库混淆

另外，记录下我的proguard内容，很多部分是拜《App研发录》的帮助，有兴趣的可以看看这本书（非广告）：
