Question

如何在移动设备开启时使用嵌套类在Android中启动服务？

我的包中包含嵌套类。

包名称

com.android

MainActivity
广播接收器

我正在尝试重新启动BroadCast接收器。但它不起作用（失败）。我不知道原因是什么，因为嵌套类有任何问题。

 <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

将BroadcastReceiver作为嵌套类。如果是的话，不要这样做。

1）如果你有接收器作为嵌套类，动态地在活动中注册它，不要在清单

中注册

2）如果您在清单中注册，请为Receiver单独创建课程。

Android系统。重新启动我的BroadCast接收器。不工作。
