如何在Oreo上运行接收广播的服务？

Question

因此，我正在尝试创建一个电池统计安卓应用程序，但我既不能接收使用broadcastmanager的broadcast，因为它不适用于安卓奥利奥和我的service在后台运行超过几分钟。我的问题是，我如何接收电池广播，如插头，拔出，电平.....在android oreo api 26+上的后台

我从销毁的活动中运行服务

/////my service code/////
public class bservice extends Service {

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

}

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    IntentFilter ifl = new IntentFilter();
    registerReceiver(bcr,new IntentFilter(Intent.ACTION_POWER_DISCONNECTED));
    registerReceiver(bcr,new IntentFilter(Intent.ACTION_POWER_CONNECTED));
    registerReceiver(bcr,new IntentFilter(Intent.ACTION_BATTERY_CHANGED));
    registerReceiver(bcr,new IntentFilter(Intent.ACTION_SCREEN_OFF));
    registerReceiver(bcr,new IntentFilter(Intent.ACTION_SCREEN_ON));
    registerReceiver(bcr,ifl);
    new Thread(new Runnable() {
        @Override
        public void run() {
            try {
                Thread.sleep(10000);
                update();
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
    }).start();
    Log.d("msg","running in background 1");
    return Service.START_STICKY;
}

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

private final BroadcastReceiver bcr = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        update();
        Log.d("msg","running in background 2");
    }
};

@Override
public void onDestroy() {
    super.onDestroy();
    //unregisterReceiver(bcr);
    Log.d("msg","service destroyed");
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        startForegroundService(new Intent(this,bservice.class));
        Log.d("msg","serv restarted");
    }

}

void update()
{.......... my updating code
    updaten(pct,cc,isCharging,isCharging);

}

Notification notification;
NotificationManager notificationManager;

void updaten(float pct,float cc,boolean a,boolean ot)
{.........my notification update code

        notificationManager.notify(id, notification);

    }
}
}

使用JobIntentService代替Service，然后从服务中动态注册广播接收器。
