Question

我正在使用广播接收器在设备关闭并再次打开时执行某些操作，但它们不起作用。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");
    }
}

请帮帮我。谢谢。

Answer 1

请务必在清单中请求RECEIVE_BOOT_COMPLETED权限：

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

如果Android设备关闭并且无法正常工作，则为broadcastreceiver
