Umeng Push - litonghui/TechBlog GitHub Wiki

Android应用在接Umeng Push SDK 中遇到一个Toast 提示，遇到一个奔溃，具体如下：

一，PushSDK 3.0遇到Toast提示：mPushAgent.register should be called in both main process and channel process!

解决方案：PushSDK 3.0初始化时，需在Application类的onCreate中调用mPushAgent.register方法来进行注册。请勿在调用register方法时做进程判断处理，主进程和channel进程（推送进程）均需要调用register才能保证长连接的正确建立。

二，奔溃信息

解决方案：增加混淆配置
