android - 在 android 设备关闭和打开不工作的情况下广播接收器

Question

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

  <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。在此先感谢。

请务必RECEIVE_BOOT_COMPLETED在清单中请求许可：

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