我已经阅读了关于这个主题的每个Stackoverflow答案,但它们都没有奏效.

目标:始终保持我的服务全天候运行

问题:每当我的设备处于睡眠模式一小时或更长时间时,服务就会被终止

我试图解决它:

• 返回START_STICKY从onStartCommand()使用startForeground()

      public int onStartCommand(Intent intent, int flags, int startId) {
  
          notification = makeStickyNotification(); //I've simplified the irrelevant code, obviously this would be a real notification I build
  
          startForeground(1234, notification);
          return START_STICKY;
          }

这样工作正常,它甚至可以在设备内存不足时重新启动我的服务,但这还不足以解决我的设备暂停一段时间后出现的问题.

• 在onCreate()我的Activity和onStartCommand()我的服务中使用Alarm Manager 来调用调用我的服务的广播接收器

          Intent ll24 = new Intent(this, AlarmReceiver.class);
  
          PendingIntent recurringLl24 = PendingIntent.getBroadcast(this, 0, ll24, PendingIntent.FLAG_CANCEL_CURRENT);
  
          AlarmManager alarms = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
  
          alarms.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), 1000*60, recurringLl24); // Every minute

这有助于保持我的服务活跃,但同样,不能解决我的问题

我有一个Android Service类,其代码如下:

public class LoginService extends Service {
BroadcastReceiver wifiStateChangeReciever;

@Override
public IBinder onBind(Intent arg0) {
    return null;
}

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    Log.i("AndroidLearning", "Service onStartCommand Started.");
    return Service.START_STICKY;
}

@Override
public void onCreate() {
    super.onCreate();
    Log.i("AndroidLearning", "Service Started.");

    final IntentFilter intentFilter = new IntentFilter();
    // intentFilter.addAction("android.net.wifi.WIFI_STATE_CHANGED");
    intentFilter.addAction("android.net.wifi.STATE_CHANGE");
    wifiStateChangeReciever = new WifiStateChangeReciever();
    this.registerReceiver(wifiStateChangeReciever, intentFilter, null, null);

    Log.i("AndroidLearning", "Reciever Registered.");
}

@Override
public void onDestroy() {
    Log.i("AndroidLearning", "Service Destroyed.");
    this.unregisterReceiver(wifiStateChangeReciever);
}
