Whatsapp 服务如何在华为手机后台持续工作?

How Whatsapp service keep working in background in huawei phones ?

我删除了受保护应用程序的 whatsapp，但屏幕中未关闭 Whatsapp 服务下班时间.

我正在编写需要每次运行的关键应用，但我的服务在屏幕关闭时被终止.

AppLifeService

public class AppLifeService extends Service {
@Override
public IBinder onBind(Intent intent) {

    return null;
}



@Override
public void onCreate() {
    super.onCreate();

}

@Override
public int onStartCommand(Intent intent, int flags, int startId) {

    super.onStartCommand(intent, flags, startId);


    startForeground(5, AppLifeReciever.createNotification(this));


    return  START_STICKY;
}


@Override
public void onDestroy() {


    //startService(new Intent(this, AppLifeService.class)); Updated : not need


    super.onDestroy();

}
}

推荐答案

@Sohail Zahid 答案告诉您一种在停止时重复启动服务一次又一次的方法.但是为了让服务保持活力，就像在后台播放歌曲一样.

@Sohail Zahid Answer tells you a way to repeatedly start a service again and again when stopped. But in order to keep a service alive like playing a song in a background.

我发现最好的方法是

startForeground(int, Notification)

对于每个通知来说，int 值必须是唯一的

where int value must be unique for every notification

您需要为方法提供一个 Notification，该方法显示在 Ongoing 部分的 Notifications Bar 中.通过这种方式，应用程序将在后台保持活动状态，不会出现任何中断.

You'll need to supply a Notification to the method which is displayed in the Notifications Bar in the Ongoing section. In this way the app will keep alive in background without any interuption.
