android - broadcastreceiver 在 android 设备关闭和打开不工作的情况下

Question

我正在使用广播接收器在设备关闭并再次打开时执行一些操作，但它们不工作。这些是 list 文件中的接收器:

  <receiver android:name=".ShutdownReceiver" >
            <intent-filter>
                <action android:name="android.intent.action.ACTION_SHUTDOWN" />
            </intent-filter>
            <intent-filter>
                <action android:name="android.intent.action.QUICKBOOT_POWEROFF" />
            </intent-filter>
        </receiver>
        <receiver android:name=".RestartReceiver" >
            <intent-filter>
                <action android:name="android.intent.action.BOOT_COMPLETED" />
            </intent-filter>
        </receiver> 

这些是相应的类:

public class ShutdownReceiver extends BroadcastReceiver 
{
    @Override
    public void onReceive(Context context, Intent intent) 
    {
        Log.d("In","Switched Off");
    }
}

public class RestartReceiver extends BroadcastReceiver 
{
    @Override
    public void onReceive(Context context, Intent intent) 
    {
        SecureMessagesActivity.ToDoOnMobileSwitchOn();
        Log.d("In","Switched On");
    }
}

请帮助我。提前致谢。

请务必在 list 中请求 RECEIVE_BOOT_COMPLETED 权限:

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>
