如果打开的ProGuard，你应该添加下面的规则在您proguard-rules.pro

-keep class your package name.template.bean.** {*;} 
-keep class your package name.wxapi.bean.** {*;} 
-keep class de.greenrobot.event.** {*;} 
-keepclassmembers,includedescriptorclasses class ** { 
    public void onEvent*(**);`enter code here` 
    void onEvent*(**); 
} 

#all the beans you post with eventbus.post
