关于#Android#DFU的问题，如何解决？

Question

Android NORDIC DFU出现如下问题：（当我在NORDIC的源码下增加一个Activity进行DFU时是成功的)
I/DfuBaseService: Starting DFU service in foreground
E/DfuService: ok
I/DfuBaseService: Connecting to the device
I/BluetoothAdapter: STATE_ON
D/BluetoothGatt: connect() - device: CE:C6:E3:ED:74:D6, auto: false
I/BluetoothAdapter: isSecureModeEnabled
D/BluetoothGatt: registerApp()
D/BluetoothGatt: registerApp() - UUID=c8f76522-bbef-4769-8c68-8055d13c94a3
D/BluetoothGatt: onClientRegistered() - status=0 clientIf=13
D/BluetoothGatt: onClientConnectionState() - status=133 clientIf=13 device=CE:C6:E3:ED:74:D6
E/DfuBaseService: Connection state change error: 133 newState: 0
E/DfuBaseService: An error occurred while connecting to the device:133

手机已经进入了DFU模式的了
代码：
String filePath = "/storage/emulated/0/DCIM/NV42.zip";
String addr = ProjectSession.getInstance().deviceInfo.uuid;
String devname = ProjectSession.getInstance().deviceInfo.name;
String deviceModel = ProjectSession.getInstance().deviceInfo.model;
devname = devname.replace(deviceModel,"").trim();
devname = "DFU " + devname;
int fileTypeTmp = DfuService.TYPE_AUTO;
Integer scope = DfuServiceInitiator.SCOPE_APPLICATION;
DfuServiceListenerHelper.registerProgressListener(context, dfuProgressListener);
if (devname.equals("DFU 6D47")== false && addr.equals("CE:C6:E3:ED:74:D7") == false)
return;
final DfuServiceInitiator dfuservice = new DfuServiceInitiator(addr)
.setDeviceName(devname)
.setKeepBond(true)
.setPrepareDataObjectDelay(400)
.setUnsafeExperimentalButtonlessServiceInSecureDfuEnabled(true);
dfuservice.setZip(filePath);
if (scope != null)
dfuservice.setScope(scope);
dfuservice.start(context, DfuService.class);

同样的代码，我在nordic的Android-nRF-Toolbox-master源码DFU文件夹里建立一个Activity，然后进行DFU是没问题的。但放到我app里就出这样的问题。还有DfuBaseService是nordic写好的Service。
