你能帮帮我吗？如果你还需要什么，我可以给你更多的信息。

Answer 1

如果你打开proguard，你应该在proguard-rules.pro上添加以下规则

-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

希望可以帮到你
