桌面java应用程序通过USB复制和传输android数据(Desktop java app copy and transfer android data via USB)

 我有一个桌面java应用程序，也是一个Android应用程序。 两个应用程序一起工作 
 

 桌面应用程序中的用户有一个按钮来启动设备数据应用程序与计算机应用程序之间的传输，反之亦然。 
 

 所以我需要用简单的USB线传输数据，没有互联网连接/ WiFi /蓝牙/ adb。 
 

 我发现两个可以在Windows上运行的Java MTP库来解决我的问题，以及android的USB Host / accesory功能： 
 

     
 
  •  jMTP成功识别我的Android设备，文件夹和其他内容 
     我成功地在计算机--->设备中传输文件，但是当我尝试在设备中传输文件时出错 - >计算机 
     我在解释后把我的代码放了。 
    •  
 
  •  jusbpmp但我没有可能转移设备--->电脑。 
    •  
 
  •  USB主机/附件没有用，因为传输是从桌面应用程序启动的，当我在android开发者指南网站上阅读时，它似乎与我需要的不一致，或者可能是用户从设备开始传输。 
    •  

 

 我尝试从1周到成功完成这项任务，但似乎我需要帮助。 
 

 Java + jMTP代码 
 

private static void jMTPeMethode() 
        {
            PortableDeviceManager manager = new PortableDeviceManager();
            PortableDevice device = manager.getDevices()[0];
            // Connect to USB tablet
            device.open();

            System.out.println(device.getModel());

            System.out.println("---------------");

            // Iterate over deviceObjects
            for (PortableDeviceObject object : device.getRootObjects()) 
            {
                // If the object is a storage object
                if (object instanceof PortableDeviceStorageObject) 
                {
                    PortableDeviceStorageObject storage = (PortableDeviceStorageObject) object;

                    for (PortableDeviceObject o2 : storage.getChildObjects()) 
                    {
                        if(o2.getOriginalFileName().equalsIgnoreCase("Test"))
                        {

                            //Device to computer not working
                            PortableDeviceToHostImpl32 copy = new PortableDeviceToHostImpl32();
                            try 
                            {
                                copy.copyFromPortableDeviceToHost(o2.getID(), "C:\\TransferTest", device);
                            } catch (COMException ex) 
                            {

                            }

    //                      //Host to Device working
    //                      BigInteger bigInteger1 = new BigInteger("123456789");
    //                      File file = new File("c:/GettingJMTP.pdf");
    //                      try {
    //                          storage.addAudioObject(file, "jj", "jj", bigInteger1);
    //                      } catch (Exception e) {
    //                          //System.out.println("Exception e = " + e);

                        }
                        System.out.println(o2.getOriginalFileName());
                    }
                }
            }

            manager.getDevices()[0].close();
        }

 

 这是代码和错误的结果

 我在互联网上读到0x80070057是一个通用的Windows异常。 
 

 编辑： 
 

 Windows站点说 hr错误ERROR_INVALID_PARAMETER 0x80070057：应用程序提供的参数无效。 
 

 但我没有看到女巫参数无效 
 

 

 这里是用于传输数据设备到计算机的库的C类链接 ，你可以看到我的错误行230。 
 

 这是我使用的jMTP库。 
 

 你能帮助我，还是用其他方式去做我需要的东西（Usb4Java，libUSB）？ 我将非常感激。 
 

 谢谢你提前。 

I have a desktop java app, and also an android app. Two app work together.
 

The user in desktop app have a button to launch the transfer between device data app to computer app and vice versa.
 

So I need to transfer data with a simple USB cable, and without internet connection/WiFi/Bluetooth/adb.
 

I found two Java MTP library that works on Windows to resolve my problem, and the USB Host/accesory fonctionnality of android:
 

     
 
  • jMTP successfully recognizes my Android devices, folder, and other things
     
    I have success to transfer a file in computer ---> device, but i have an error when i try to transfer a file in device ---> computer
     
    I put my code after the explaination.
    •  
 
  • jusbpmp but i don't have the possibility to transfer device ---> computer.
    •  
 
  • USB Host/accesory not usefull because transfer are launch from desktop app, and when i read on the android developper guide website, it seems to be not correspond from what i need, or maybe if the user start transfer from the device.
    •  

 

I try from 1 week to success in this task but it seems i need help.
 

Java + jMTP code

I read in internet 0x80070057 is a generic windows exception .
 

Edit: 
 

Windows site say for the hr error ERROR_INVALID_PARAMETER 0x80070057 : The parameter supplied by the application is not valid.
 

But i don't see witch parameter is not valid
 

 

Here is the link of C class of the library use for transfer data device to computer, you can see my error line 230.
 

And this is the jMTP library i use.
 

Can you help me, or purpose an other way to do what i need(Usb4Java, libUSB) ? I shall be really grateful.
 

Thanks by advance.

  •  如果希望以巴黎为center初始化地图，请将其用于center MapOption （而不是标记的中心属性）。 
    •  

 

function initialize() {
    var mapDiv = document.getElementById('map-canvas');
    var mapOptions = {
        center: paris,
        zoom: 8,
        zoomControl: false,
        scrollwheel: false,
        disableDoubleClickZoom: true
    }
    map = new google.maps.Map(mapDiv, mapOptions);

 

     
 
  •  infowindow“auto pan”正在干扰地图中心（你正在打开3个infowindows，一个接一个，平底锅互相干扰。将{disableAutoPan: true}添加到infowindow选项。

  • If you want the map to be initialized centered on Paris, use that for the center MapOption (not the center property of a marker).
    •  

 

function initialize() {
    var mapDiv = document.getElementById('map-canvas');
    var mapOptions = {
        center: paris,
        zoom: 8,
        zoomControl: false,
        scrollwheel: false,
        disableDoubleClickZoom: true
    }
    map = new google.maps.Map(mapDiv, mapOptions);

 

     
 
  • the infowindow "auto pan" is interferring with the map center (you are opening 3 infowindows, one right after another, the pans are interfering with each other. Add {disableAutoPan: true} to the infowindow options.
