Android不混淆没问题，混淆后一打开就报错

每个项目的混淆代码基本都不一样，注意一下几点 1.解析json的实体类不要混淆 2.实现Serializable与Parcelable接口的类不要混淆 3.第三代jar包尽量不混淆，如果需要的话查询他们的混淆规则

[在清晨]

这个类com.yundcm.base.AppContext被混淆了, 干掉了 你要修改proguard文件, 把它keep下来.

[UESTC少尉]

1楼说的几点确实要注意，混淆可能出现的问题比较多的，现在第三方的一些安全加固平台倒是比较好用的，可以看看(梆梆、阿里聚安全...)

[ESC尛蜜蜂]

个人感觉混淆现在没什么用，只是优化了下代码，删除了重复代码，增加了反编译后阅读的难度，一般都是通过在apk上加个套子，防止反编译，很多第三方都提供这种服务，我就不举例了

dn't find class "com.yundcm.base.AppContext" on path: DexPathList 这已经说了，这个类不要混淆

可是我都-keep public class com.yundcm.base.AppContext这样写了，或者-dontwarn com.yundcm.base.** -keep class com.yundcm.base.** { *;}，，这样都不行，还是这个错
