我尝试使用位于我 PC 上的共享文件夹中的图像文件创建 Gdx 纹理。该代码在桌面应用程序上运行良好（但在不使用 SmbFile 的情况下也能正常运行......），但在 android 应用程序上崩溃。我收到“没有这样的文件或目录”错误。有人知道我们该怎么做吗？谢谢 ！

        public void create () {
        Gdx.app.setLogLevel(Application.LOG_DEBUG);

        batch = new SpriteBatch();

        SmbFile file=null;

        try {
            file = new SmbFile("smb://***path to shared folder***/icon-152.png");
        } catch (MalformedURLException e) {
            e.printStackTrace();
        } catch (Exception e) {
            e.printStackTrace();
        }
        FileHandle fileHandle;
        fileHandle = new FileHandle(file.getUncPath());

        img = new Texture(fileHandle); //***No such file or directory***
        //img = new Texture(Gdx.files.external(file.getUncPath())); //***No such file or directory***
    }

补充：我尝试将文件复制到资产中，然后将其作为纹理加载。在桌面应用程序上仍然可以正常工作，但在 android 应用程序上仍然出现错误：Java.io.FiliNotFound Exception。

    public void create () {
        Gdx.app.setLogLevel(Application.LOG_DEBUG);

        batch = new SpriteBatch();

        SmbFile file=null;

        try {
            file = new SmbFile("smb://***path to shared folder***/icon-152.png");
        } catch (MalformedURLException e) {
            e.printStackTrace();
        } catch (Exception e) {
            e.printStackTrace();
        }

        InputStream is = null;
        OutputStream os = null;
        try {
            is = new FileInputStream(file.getUncPath());
            os = new FileOutputStream("test.png");
            byte[] buffer = new byte[1024];
            int length;
            while ((length = is.read(buffer)) > 0) {
                os.write(buffer, 0, length);
            }
            is.close();
            os.close();
        }
        catch(java.io.IOException e){
            Gdx.app.log("", e.getMessage()); //***Java.io.FileNotFound Exception***
        }

        img = new Texture("test.png"); //***No such file or directory***

    }

Yes Nicolas,

I finaly did it by first copying the file in local. It is working on both android and desktop app. If somebody is interested, the two functions loadFile and saveFile :


        loadFile( "//***path to shared folder***/icon-152.png","icon-152.png");

        saveFile("icon-152.png", "//HP2285/***path to shared folder***/icon-152.png");

    }

    public void loadFile(String smbFilePath, String fileName){

        try {
            SmbFile file = new SmbFile("smb:"+smbFilePath);
            InputStream is = new SmbFileInputStream(file);

            FileHandle fhd = Gdx.files.local(fileName);
            OutputStream os = fhd.write(false);

            byte[] buffer = new byte[1024];
            int length;
            while ((length = is.read(buffer)) > 0) {
                os.write(buffer, 0, length);
            }

            is.close();
            os.close();
        }
        catch(Exception e){
        }
    }

    public void saveFile(String fileName, String smbFilePath){

        try {
            SmbFile file = new SmbFile("smb:"+smbFilePath);
            OutputStream os = new SmbFileOutputStream(file);

            FileHandle fhs = Gdx.files.local(fileName);
            InputStream is = fhs.read();

            byte[] buffer = new byte[1024];
            int length;
            while ((length = is.read (buffer)) > 0) {
                os.write(buffer, 0, length);
            }

            is.close();
            os.close();
        }
        catch(Exception e){
        }

    }
