android - 如何让服务保持活力？

Question

Whatsapp 服务如何在华为手机中保持后台运行？

我删除了 protected 应用程序的 whatsapp 但 Whatsapp 服务没有在屏幕上关闭休息时间。

我正在编写每次都需要运行的关键应用程序，但我的服务在屏幕关闭时终止。

我想写类似Whatsapp或AirDroid服务的服务谁能解释一下？

我的意思是在华为手机中如何写专门不熄屏关闭的服务

这是我的服务代码

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();

}
}

您需要创建一个 Service 以在 BroadcastService 关闭时自动“重新打开”。

例如:

广播服务

public class MyBroadcastService extends BroadcastReceiver
{

 @Override
    public void onReceive(final Context context, Intent intent)
    {
     //do something
    }
}

服务自动“重启”

public class MyService extends Service
{

@Override
    public void onCreate()
    {
        // Handler will get associated with the current thread,
        // which is the main thread.
        super.onCreate();
        ctx = this;

    }

 @Override
    public IBinder onBind(Intent arg0)
    {
        // TODO Auto-generated method stub

        return null;
    }

@Override
    public int onStartCommand(Intent intent, int flags, int startId)
    {
        Log.i(TAG, "onStartCommand");
        //Toast.makeText(this, "onStartCommand", Toast.LENGTH_LONG).show();

        return START_STICKY;
    }

//launch when its closed
@Override
    public void onDestroy()
    {
        super.onDestroy();
        sendBroadcast(new Intent("YouWillNeverKillMe"));
        Toast.makeText(this, "YouWillNeverKillMe TOAST!!", Toast.LENGTH_LONG).show();
    }
}

在您的 AndroidManifest.XML 上声明

<receiver android:name=".BroadcastServicesBackground.MyBroadcastService">
            <intent-filter>
                <!--That name (YouWillNeverKillMe) you wrote on Myservice-->
                <action android:name="YouWillNeverKillMe"/>

                <data android:scheme="package"/>
            </intent-filter>
            <intent-filter>
                 <!--To launch on device boot-->
                <action android:name="android.intent.action.BOOT_COMPLETED"/>
            </intent-filter>
        </receiver>

        <service android:name=".Services.MyService"/>
