安卓。重新启动我的广播接收器。不工作。

Question

当手机开机时，如何使用嵌套类在android中启动服务？

我的包包含嵌套类。

包名称

com.android

1. MainActivity
2. BroadCastReceiver

我正在尝试重新启动我的 BroadCast 接收器。但它不起作用（失败）。我不知道原因是否是由于嵌套类的任何问题。

 <receiver android:name="ConnectionReceiver"></receiver> 

<receiver android:name="com.android.MainActivity .BroadCastReceiver "> 
<intent-filter> 
<action android:name="android.intent.action.BOOT_COMPLETED" /> 
</intent-filter> 
</receiver>

Answer 2

R u 将 BroadcastReceiver 作为嵌套类。如果是，请不要这样做。

1）如果您将接收器作为嵌套类，请在活动中动态注册它，不要在清单中注册

2）如果您在清单中注册它，请为接收器创建单独的类。
