Beacon connect and change Major, Minor ID

1

Hi, I am developer with “Estimote” beacon and “Android studio application”.
I’m trying to change my beacon’s major minor ID with my own app(Android studio)!!
So I made an App about that.

public class MainActivity extends AppCompatActivity {

private BeaconConnection beaconConnection;
DeviceConnectionProvider connectionProvider;
List<ConfigurableDevice> deviceList;
DeviceConnection connection;
private boolean connectedToTheConnectionProvider;
ConfigurableDevicesScanner deviceScanner;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    EstimoteSDK.initialize(getApplicationContext(), "capston-kdd", "c58b9a1b27bc540fe1fe409219e3064f");
    EstimoteSDK.enableDebugLogging(true);

    connectionProvider = new DeviceConnectionProvider(this);
    connectionProvider.connectToService(new DeviceConnectionProvider.ConnectionProviderCallback() {
        @Override
        public void onConnectedToService() {
            // Handle your actions here. You are now connected to connection service.
            // For example: you can create DeviceConnection object here from connectionProvider.
            connectedToTheConnectionProvider = true;

        }
    });

//    beaconConnection = BeaconConnection.getInstance(this);
  //  beaconConnection.setConnectionProvider();

}

@Override
protected void onResume() {
    super.onResume();

    if (SystemRequirementsChecker.checkWithDefaultDialogs(this)) {

        deviceScanner = new ConfigurableDevicesScanner(this);
        //deviceScanner.setOwnDevicesFiltering(true);
        //deviceScanner.setDeviceTypes(DeviceType.LOCATION_BEACON);
        deviceScanner.scanForDevices(new ConfigurableDevicesScanner.ScannerCallback() {
            @Override
            public void onDevicesFound(List<ConfigurableDevicesScanner.ScanResultItem> devices) {
                deviceScanner.stopScanning();

                for(ConfigurableDevicesScanner.ScanResultItem item : devices) {
                    Log.d("Scanned Beacon:","--" + item.device.macAddress.toString() + "--" + item.device.deviceId + "--");
                    deviceList.add(item.device);
                }
            }
        });

        if (connectedToTheConnectionProvider){
            connection = connectionProvider.getConnection(deviceList.get(0));
            connection.connect(new DeviceConnectionCallback() {
                @Override
                public void onConnected() {
                    // Do something with your connection.
                    // You can for example read device settings, or make an firmware update.
                    Log.d("DeviceConnection", "onConnected");

                    // Take your connected DeviceConnection object and get it's editor
                    SettingsEditor edit = connection.edit();
                   // edit.set(connection.settings.beacon.proximityUUID(), UUID.fromString("B9407F30-F5F8-466E-AFF9-25556B57FE6D"));
                    edit.set(connection.settings.beacon.major(), 11);
                    edit.set(connection.settings.beacon.minor(), 22);
                    edit.commit(new SettingCallback() {
                        @Override
                        public void onSuccess(Object value) {
                            // Handle success here. It will be called only when all settings have been written.
                            Log.d("DeviceBulkWrite","Bulk write successful");
                        }

                        @Override
                        public void onFailure(DeviceConnectionException exception) {
                            // Handle exceptions
                            Log.d("DeviceBulkWrite","Bulk write failed");
                        }
                    });
                }


                @Override
                public void onDisconnected() {
                    // Every time your device gets disconnected, you can handle that here.
                    // For example: in this state you can try reconnecting to your device.
                    Log.d("DeviceConnection", "onDisconnected");
                }

                @Override
                public void onConnectionFailed(DeviceConnectionException exception) {
                    // Handle every connection error here.
                    Log.d("DeviceConnection", "onConnectionFailed");
                }
            });
        }

    }
}

@Override
protected void onStop() {
    super.onStop();
}

@Override
protected void onPause() {
    super.onPause();

    if (deviceScanner!=null && deviceScanner.isScanning()){
        deviceScanner.stopScanning();
    }
}

@Override
protected void onDestroy() {


    if (connectionProvider!=null)
        connectionProvider.destroy();

    connection.destroy();

    super.onDestroy();

    //deviceConnection.close();
}

}

But… there are some problem.
When I started my app, That was killed because of some errors. But I don’t know why…
If you can teach me or solve this problem, please don’t hesitate to say to me.
Thank you.
