仅在Oreo(8.0)中接收推送通知时，应用程序崩溃.

App is crashing while receiving push notification in Oreo(8.0) only .

java.lang.RuntimeException: Unable to instantiate receiver com.google.firebase.iid.FirebaseInstanceIdReceiver: java.lang.ClassCastException: android.content.ContextWrapper cannot be cast to android.app.ContextImpl
        at android.app.ActivityThread.handleReceiver(ActivityThread.java:3236)
        at android.app.ActivityThread.-wrap17(Unknown Source:0)
        at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1677)

推荐答案

使用书法库时，我遇到了同样的问题. Firebase首次请求令牌时，即使在安装后第一次崩溃.不仅会收到推送通知.

I was facing the same issue when using Calligraphy library. Even it was crashing the first time after installing when Firebase requests a token for the first time. Not only receiving push notifications.

我的错误是我正在重写Application类中的attachBaseContext方法以返回ContextWrapper对象，但仅在Activity中需要.

My error was I was overriding attachBaseContext method in my Application class to return a ContextWrapper object, but was only needed in Activities.

因此，恢复我的解决方案是在Application类中删除attachBaseContext并将其移动或仅将其放入活动中.

So to resume my solution is to remove attachBaseContext in Application class and move it or just place it into activities.
