如何让AltBeacon库的BootstrapRegion识别iBeacon布局?

我在使用参考, http://altbeacon.github.io/android-beacon-library/samples.html 。我还使用了 How to detect Region Enter/Exit for multiple beacons using AltBeacon android-beacon-library?

我正在尝试使用AltBeacon的Android Beacon Library在后台检测iBeacons。我包含了项目中的以下代码片段。到目前为止,我没有在背景中检测到ibeacons。。。谢谢你的帮助

我正在使用Beacon Manager

setBeaconLayout("m:2-3=0215,i:4-19,i:20-21,i:22-23,p:24-24"));

然而,我没有得到错误和信标检测。在三星Galaxy 4设备上调试运行应用程序时,应用程序会启动,但不会检测到活动信标。我的信标是雷达信标,配置为iBeacons。Rad Beacon应用程序检测到它们,我在前台运行的其他AltBeacon库应用程序也检测到我的iBeacons。这些应用程序正在三星Galaxy 4上运行。

我为背景信标检测设置的应用程序。。。不检测iBeacons。

这是我的代码。对Constants.java的引用只是我的应用程序的一个常量文件。

    Log.d(TAG, "Got a didEnterRegion call");

    // This call to disable will make it so the activity below only gets launched the first time a beacon is seen (until the next time the app is launched)
    // if you want the Activity to launch every single time beacons come into view, remove this call.  
    regionBootstrap.disable();
    Intent intent = new Intent(this, MainActivity.class);
    // IMPORTANT: in the AndroidManifest.xml definition of this activity, you must set android:launchMode="singleInstance" or you will get two instances
    // created when a user launches the activity manually and it gets launched from here.
    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    this.startActivity(intent);
}

@Override
public void didExitRegion(Region arg0) {
    // Don't care
}  


/*

    @Override

        if (beacons.size() > 0) {
            Log.i(TAG, "The first beacon I see is about "+beacons.iterator().next().getDistance()+" meters away.");     
        }
    }
    });

    try {
        beaconManager.startRangingBeaconsInRegion(new Region("myRangingUniqueId", null, null, null));
    } catch (RemoteException e) {   }

}

我没有得到任何ibeacon检测。没有发布预期的LogCat列表。我是不是漏了一步?
