Altbeacon库样本似乎并没有在后台工作 [英] Altbeacon Library sample doesn't seem to work in the Background

问题描述

我已经使用了基本的样本由 Altbeacon 规定（无线网络）的GitHub库的应用程序。

I have used the basic sample application provided by Altbeacon (Radio Network) on the Github repo.

一切似乎都在为我的iBeacon直接从监控到测距但只有在前景

Everything seems to work for my iBeacon right from Monitoring to the Ranging but only in Foreground

我所做的这些下面的步骤来获得它在前台工作。

I have done these following steps to get it working in Foreground.

public class BeaconReferenceApplication extends Application implements BootstrapNotifier, RangeNotifier
{

private static final String TAG = "BeaconReferenceApplication";
private BeaconManager mBeaconManager;
private Region mAllBeaconsRegion;
private BackgroundPowerSaver mBackgroundPowerSaver;
private RegionBootstrap mRegionBootstrap;
private BackgroundPowerSaver backgroundPowerSaver;

@Override
public void onCreate()
{
    mAllBeaconsRegion = new Region(getPackageName(), null, null, null);

    mBeaconManager = BeaconManager.getInstanceForApplication(this);
    mBackgroundPowerSaver = new BackgroundPowerSaver(this);
    mRegionBootstrap = new RegionBootstrap(this, mAllBeaconsRegion);
    mBeaconManager.getBeaconParsers().add(new BeaconParser().setBeaconLayout("m:2-3=0215,i:4-19,i:20-21,i:22-23,p:24-24"));
    backgroundPowerSaver = new BackgroundPowerSaver(this);
}

@Override
public void didRangeBeaconsInRegion(Collection<Beacon> arg0, Region arg1)
{
    System.out.println("app-> didRangeBeaconsInRegion");
}

@Override
public void didDetermineStateForRegion(int arg0, Region arg1)
{
    System.out.println("app-> didDetermineStateForRegion");
}

@Override
public void didEnterRegion(Region arg0)
{
    System.out.println("app-> didEnterRegion");
    try
    {
        Log.d(TAG, "entered region.  starting ranging");
        mBeaconManager.setRangeNotifier(this);
        mBeaconManager.startRangingBeaconsInRegion(mAllBeaconsRegion);
    }
    catch(RemoteException e)
    {
        Log.e(TAG, "Cannot start ranging");
    }

    Intent intentMainActivity = new Intent(this,MonitoringAndRangingActivity.class);
    intentMainActivity.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    startActivity(intentMainActivity);
}

@Override
public void didExitRegion(Region arg0)
{
    System.out.println("app-> didExitRegion");
}

public void setMonitoringAndRangingActivity(MonitoringAndRangingActivity activity)
{
    mBeaconManager.setBackgroundMode((activity==null)?true:false);
}

}

编辑：我添加的方法 mBeaconManager.setBackgroundMode（真）; ，但没有任何帮助，我只是得到从 BlutoothAdapter 的stopLE扫描（）消息，一切都停止，我需要的服务或别的什么来实现呢？

I have added the method mBeaconManager.setBackgroundMode(true); but no help, i just get the stopLE scan() message from BlutoothAdapter and everything stops, do i need to implement this in a Service or anything else?

但只要我去后台（pressing回或家庭）的日志和回调方法停止响应。 这有什么，我很想念激活背景iBeacon检测。

But as soon as I go to background(pressing back or home) the logs and the callback methods stop responding. Is there anything that i am missing to activate the background iBeacon detection.

任何投入就如同一个福音。

Any inputs would be like a boon.

推荐答案

在 BackgroundPowerSaver 它会自动转换了Android灯塔图书馆为背景模式。有没有需要调用 setBackgroundMode 手动。

If you are using the BackgroundPowerSaver it will transition the Android Beacon Library into background mode automatically. There is no need to call setBackgroundMode manually.

在该库在后台模式下，它只是做了扫描，每5分钟，以节省功率（这个时间是可以配置的），所以它可能需要长达五分钟检测一盏明灯。我会看LogCat中五分钟，而你的ASPP是在后台，看看你在任何时间检测。如果没有，添加LogCat中摘录到你的问题将是有益的。

When the library is in background mode, it only does a scan every 5 minutes to save power (this timing is configurable) so it may take up to five minutes to detect a beacon. I would watch LogCat for five minutes while your aspp is in the background and see if you get any detections in that time. If not, adding a LogCat excerpt to your question would be helpful.
