Android 6.0 nicht sehen Beacon

Question

Ich habe Android 6.0 Telefon. Diese App sieht den Beacon nicht. I am getting this error

I/BluetoothLeScanner: startRegisteration: mLeScanClients = {org.altbeacon.beacon.service.scanner.CycledLeScannerForLollipop $ 4 @ 5445b45 = android.bluetooth.le.BluetoothLeScanner $ BleScanCallbackWrapper @ d9ce5fa}. 

Können Sie mir helfen?

public class MainActivity extends AppCompatActivity implements BeaconConsumer { 
private BeaconManager beaconManager; 
private Beacon nearestBeacon; 

private static final int PERMISSION_REQUEST_COARSE_LOCATION = 1; 
private static final String TAG = "Beacon"; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    beaconManager=BeaconManager.getInstanceForApplication(this); 
    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")); 
    beaconManager.getBeaconParsers().add(new BeaconParser().setBeaconLayout("m:2-3=0215,i:4-19,i:20-21,i:22-23,p:24-24")); 
    beaconManager.setBackgroundScanPeriod(TimeUnit.SECONDS.toMillis(20)); 
    beaconManager.setBackgroundBetweenScanPeriod(TimeUnit.SECONDS.toMillis(10)); 
    beaconManager.bind(this); 



    if(Build.VERSION.SDK_INT>=Build.VERSION_CODES.M){ 
    if(this.checkSelfPermission(Manifest.permission.ACCESS_COARSE_LOCATION)!=PackageManager.PERMISSION_GRANTED){ 
     final AlertDialog.Builder builder=new AlertDialog.Builder(this); 
     builder.setTitle("This app needs location acces"); 

     builder.setMessage("Please grant location.."); 
     builder.setPositiveButton(android.R.string.ok,null); 
     builder.setOnDismissListener(new DialogInterface.OnDismissListener() { 
      @Override

     builder.show(); 

    } 
} 
}

       }); 
       builder.show(); 
      } 
      return; 
     } 
    } 
} 

@Override 
protected void onDestroy() { 
    super.onDestroy(); 
    beaconManager.unbind(this); 
} 

@Override 
    public void onBeaconServiceConnect() { 
    beaconManager.addRangeNotifier(new RangeNotifier() {

       Log.d(TAG,collection.toString()); 
       List beaconList=new ArrayList(collection); 

      } 
     } 
    }); 
    try { 
     beaconManager.startMonitoringBeaconsInRegion(new Region("myRangingUniqueID",null,null,null)); 
    } catch (RemoteException e) { 
     e.printStackTrace(); 
    } 

} 
public void getNearestBeacon(List beaconList) { 
    for(int i=0; i<beaconList.size(); i++) 
    { 
     Beacon tempBeacon=((Beacon) beaconList.get(i)); 
     if(tempBeacon.getId3() != nearestBeacon.getId3())

     } 
    } 
    // t1.setText(nearestBeacon.getId2().toString()); 
    Log.d(TAG,"Beacon'ın Majoru: " + nearestBeacon.getId2()); 


} 
}

Ich bin nicht sicher, was für Ihre Anwendung nicht in Ordnung ist, aber für das Scannen auf Android 6, ist es wichtig, dass:

• bluetooth auf
• Lage ist, auf
• Standort Erlaubnis erteilt

Suchen Sie nach iBeacons? In diesem Fall können Sie diese Bibliothek ausprobieren: https://github.com/inthepocket/ibeacon-scanner-android, um zu sehen, ob Sie mehr Glück haben.
