我正在使用Radius Network提供的proximity-reference-android示例应用程序来检测iBeacon。我将iPad配置为iBeacon，并在感应套件中添加了大约3个信标区域。我现在面临的问题是我无法获取Beacon名称，以及我在Android中的感应套件中获得的额外网址。
我需要在Android应用程序中显示与该信号区域相关联的网址，就像iOS应用程序一样。
调试时我已经检查过，即使在应用程序中检测到信标后， didEnterRegion 也不会被调用。我需要基本上将该特定信标的详细信息保存在数据库中被检测到。
应用程序调用 didExitRegion 。
发布以下代码，请让我知道我在做错了什么。
public class AndroidProximityReferenceApplication extends Application implements
BootstrapNotifier {
private static final String TAG = "AndroidProximityReferenceApplication";
private RegionBootstrap regionBootstrap;
private BackgroundPowerSaver backgroundPowerSaver;
private boolean haveDetectedIBeaconsSinceBoot = false;
public void onCreate() {
super.onCreate();
Log.d(TAG,
"setting up background monitoring for iBeacons and power saving");
// wake up the app when an iBeacon is seen
Region region = new Region(
"com.radiusnetworks.androidproximityreference.backgroundRegion",
"2F234454-CF6D-4A0F-ADF2-F4911BA9FFA6", null, null);
regionBootstrap = new RegionBootstrap(this, region);
// simply constructing this class and holding a reference to it in your
// custom Application
// class will automatically cause the iBeaconLibrary to save battery
// whenever the application
// is not visible. This reduces bluetooth power usage by about 60%
backgroundPowerSaver = new BackgroundPowerSaver(this);
}
@Override
public void didDetermineStateForRegion(int arg0, Region arg1) {
// This method is not used in this example
}
@Override
public void didEnterRegion(Region arg0) {
// In this example, this class sends a notification to the user whenever
// an iBeacon
// matching a Region (defined above) are first seen.
Log.d(TAG, "did enter region.");
if (!haveDetectedIBeaconsSinceBoot) {
Log.d(TAG, "auto launching MainActivity");
// The very first time since boot that we detect an iBeacon, we
// launch the
// MainActivity
Intent intent = new Intent(this, MainActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
// Important: make sure to add android:launchMode="singleInstance"
// in the manifest
// to keep multiple copies of this activity from getting created if
// the user has
// already manually launched the app.
this.startActivity(intent);
haveDetectedIBeaconsSinceBoot = true;
} else {
// If we have already seen iBeacons and launched the MainActivity
// before, we simply
// send a notification to the user on subsequent detections.
Log.d(TAG, "Sending notification.");
ParseObject beacon = new ParseObject("Beacon");
beacon.put("beacon_name", arg0.getClass().getName());
beacon.put("beacon_id", arg0.getUniqueId());

}
}

}
private void sendNotification() {
NotificationCompat.Builder builder = new NotificationCompat.Builder(
this).setContentTitle("Proximity Reference Application")
.setContentText("An iBeacon is nearby.")
.setSmallIcon(R.drawable.ic_launcher);
TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
stackBuilder.addNextIntent(new Intent(this, MainActivity.class));

PendingIntent.FLAG_UPDATE_CURRENT);
builder.setContentIntent(resultPendingIntent);
NotificationManager notificationManager = (NotificationManager) this
.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(1, builder.build());
}
}
以下代码属于 mainActivity 类
public class MainActivity extends Activity implements IBeaconConsumer,

"test345");
IBeaconManager.LOG_DEBUG = true;
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
iBeaconManager = IBeaconManager.getInstanceForApplication(this
.getApplicationContext());
iBeaconManager.bind(this);
}
@Override

Region region = new Region("MainActivityRanging", null, null, null);
try {
iBeaconManager.startRangingBeaconsInRegion(region);
iBeaconManager.setRangeNotifier(this);
} catch (RemoteException e) {
e.printStackTrace();
}
}
@Override
public void onDestroy() {
super.onDestroy();
iBeaconManager.unBind(this);
}
@Override
public void didRangeBeaconsInRegion(Collection<IBeacon> iBeacons,
Region region) {
for (IBeacon iBeacon : iBeacons) {

displayTableRow(iBeacon, displayString, false);
}
}
@Override

DataProviderException e) {
if (e != null) {
Log.d(TAG, "data fetch error:" + e);
}

}
}
private void displayTableRow(final IBeacon iBeacon,
final String displayString, final boolean updateIfExists) {

@Override

});
}
}
任何帮助都将不胜感激。谢谢：）

使用Proximity Kit for Android时，可以使用两组不同的API。一组使用ProximityKitManager，它用于更简单的用例，您可以预先配置所有iBeacon标识符和相关数据服务器端，并让ProximityKitManager处理设置范围和监视在全局Application类中。
第二组API使用IBeaconManager并提供更细粒度的控制。但由于ProximityKitManager使用了引擎盖下的IBeaconManager，因此您不应同时使用两者，因为您可以轻松地破坏ProximityKitManager完成的自动配置。我怀疑这是导致问题的原因，因为代码使用Application类中的ProximityKitManager和Activity类中的IBeaconManager。有关详细信息，请参阅here。
如果您需要跟踪信标而不管ProximityKit中设置的标识符，但仍想访问为ProximityKit中的某些iBeacons配置的数据，则不应使用ProximityKitManager而只需使用{{1 }}。有一个参考应用程序，显示如何使用此API here.
