杀死应用程序后，我的前台服务在某些设备（如vivo）上被杀死，是否有任何解决方法可以使其保持活力？

我正在使用前台服务，例如：

public class MyService extends IntentService {

    private final String TAG = "IntentService";
    private PowerManager.WakeLock wakeLock;

    public MyService() {
        super("MyService");
        setIntentRedelivery(true);
    }

    @Override
    protected void onHandleIntent(@Nullable Intent intent) {
        Log.d(TAG, "onHandleIntent: Service running");
        for (int i = 0; i < 20; i++) {
            Log.d(TAG, "onHandleIntent: service running status: " + i);
            SystemClock.sleep(3000);
        }
    }

    @Override
    public void onCreate() {
        Log.d(TAG, "onCreate: IntentService Created");
        super.onCreate();

        PowerManager powerManager = (PowerManager) getSystemService(POWER_SERVICE);
        this.wakeLock = powerManager.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK,
                "Service: WakeLock");
        this.wakeLock.acquire();
        Log.d(TAG, "onCreate: Wakelock acquired");


        Notification notification = new NotificationCompat.Builder(this, App.NOTIFICATION_CHANNEL_ID)
                .setContentTitle("Intent Service")
                .setContentText("Service running in background")
                .setSmallIcon(android.R.drawable.sym_def_app_icon)
                .build();
        startForeground(12, notification);
    }

    @Override
    public void onDestroy() {
        Log.d(TAG, "onDestroy: IntentService Destroyed");
        super.onDestroy();
        this.wakeLock.release();
        Log.d(TAG, "onDestroy: Wakelock released");
    }
}

我使用解决方法让它工作。

像这样注册一个假的静态隐式接收器：

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

<receiver android:name=".SampleBroadcast">
   <intent-filter>
      <action android:name="android.intent.action.BOOT_COMPLETED" />
   </intent-filter>
</receiver>

我的 SampleBroadcast 文件：

public class SampleBroadcast extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {

        if (Intent.ACTION_BOOT_COMPLETED.equals(intent.getAction())) {
            Log.d("Foreground App", "Boot Completed");
        }

    }
}

这将我的应用程序置于 OS 的自动启动部分。

现在当我开始我的服务时，即使我杀死了它正在运行的应用程序。
