问题
As before, I work with Android Beacon Library,
It already worked and I can found out beacon via BLE - Bluetooth low energy,
But now, after updated to latest version of library, now method onBeaconServiceConnect() not run anymore.
Please tell me what I need to do to make it works,
Thank you,
p/s : Code :
Manifest.xml

ANSWER
Since I used Fragment not Activity as sample codes from the library.
So I need do these changes :
@Override
public Context getApplicationContext() {
return getActivity().getApplicationContext();
}
@Override
public void unbindService(ServiceConnection serviceConnection) {
getActivity().unbindService(serviceConnection);
}
@Override
public boolean bindService(Intent intent, ServiceConnection serviceConnection, int i) {
return getActivity().bindService(intent, serviceConnection, i);
}
回答1:
If you are implementing the BeaconConsumer interface in a Fragment (and not an Activity, Service or Application instance), you need to chain all of the methods. Like this:
@Override
public Context getApplicationContext() {
return getActivity().getApplicationContext();
}
@Override
public void unbindService(ServiceConnection serviceConnection) {
getActivity().unbindService(serviceConnection);
}
@Override
public boolean bindService(Intent intent, ServiceConnection serviceConnection, int i) {
return getActivity().bindService(intent, serviceConnection, i);
}

I am not sure.before few days ,this beacon code is working for me.please check.if any issue ,i will send whole my code.
try this one:
beaconManager.startRangingBeaconsInRegion(new Region("myBeaons", Identifier.parse(UUID), null, null));
instead of this line in your code.
beaconManager.startRangingBeaconsInRegion(
new Region(Constant.UUID, null, null, null));

this Code is working for me.please try this code:
Create Application Class:
public class BeaconReferenceApplication extends Application implements BootstrapNotifier {
private BackgroundPowerSaver backgroundPowerSaver;
private boolean haveDetectedBeaconsSinceBoot = false;
private MonitoringActivity monitoringActivity = null;
private String UUID = "23542266-18D1-4FE4-B4A1-23F8195B9D39";

@Override
public void onCreate() {
super.onCreate();
Log.d(TAG, "App started up");
BeaconManager beaconManager = BeaconManager.getInstanceForApplication(this);
// To detect proprietary beacons, you must add a line like below corresponding to your beacon
// type. Do a web search for "setBeaconLayout" to get the proper expression.
// beaconManager.getBeaconParsers().add(new BeaconParser().
// setBeaconLayout("m:2-3=beac,i:4-19,i:20-21,i:22-23,p:24-24,d:25-25"));
// wake up the app when any beacon is seen (you can specify specific id filers in the parameters below)
Region region = new Region("com.example.myapp.boostrapRegion", null, null, null);
regionBootstrap = new RegionBootstrap(this, region);
}
@Override
public void didDetermineStateForRegion(int arg0, Region arg1) {

}

// 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.
