单击相机中的图像后，我正在尝试将图像上传到 Cloudinary。 相机工作正常，但单击图像后，应用程序一次又一次地崩溃。试图调试它，但没有得到我遇到错误的地方。

我尝试对示例图像 URL 进行硬编码，但仍然无法正常工作。 可能是这条线的问题 cloudinary.uploader().upload(photoFile.getAbsolutePath(), ObjectUtils.emptyMap());

public static final int TAKE_PHOTO_REQUEST = 0;

    @Override
    protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) 
        super.onActivityResult(requestCode, resultCode, data);

        if (requestCode == TAKE_PHOTO_REQUEST) 
            if (resultCode == RESULT_OK) 
                //File to upload to cloudinary
                Toast.makeText(this, "Pakistan Zinabad", Toast.LENGTH_SHORT).show();
                Map config = new HashMap();
                config.put("cloud_name", "nomancloud");
                config.put("api_key", "myKey");
                config.put("api_secret", "mySecretApi");
                Cloudinary cloudinary = new Cloudinary(config);

                try 
                    cloudinary.uploader().upload(photoFile.getAbsolutePath(), ObjectUtils.emptyMap());
                 catch (IOException e) 
                    e.printStackTrace();
                

             else if (resultCode == RESULT_CANCELED) 
                // User cancelled the image capture
                //finish();
            
        

    


    private File createImageFile() throws IOException 
        // Create an image file name

        String imageFileName = "capturedImage";
        File storageDir = Environment.getExternalStoragePublicDirectory(
                Environment.DIRECTORY_PICTURES);
        File image = File.createTempFile(
                imageFileName,  /* prefix */
                ".jpg",         /* suffix */
                storageDir      /* directory */
        );

        // Save a file: path for use with ACTION_VIEW intents
        return image;
    

 @Override
    public void onClick(View v) 

        Intent takePhotoIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

        if (takePhotoIntent.resolveActivity(getPackageManager()) != null) 
        // Create the File where the photo should go
        photoFile = null;

        try 
        photoFile = createImageFile();
        
        catch (IOException ex) 
        // Error occurred while creating the File
        

        // Continue only if the File was successfully created
        if (photoFile != null) 
            takePhotoIntent.putExtra(MediaStore.EXTRA_OUTPUT,
            Uri.fromFile(photoFile));
            startActivityForResult(takePhotoIntent, TAKE_PHOTO_REQUEST);
            
        
    

【参考方案1】：

您可以尝试使用：

Map uploadResult = cloudinary.uploader().upload("http://res.cloudinary.com/demo/image/upload/sample.jpg", ObjectUtils.emptyMap());

并打印 RuntimeException/uploadResult？

【参考方案2】：

尝试使用 Cloudinary 提供的适用于 Android 的 MediaManager 类。您将需要调用将在后台线程上运行的 dispatch() 方法。基本上你得到了 NetworkOnMainThread 异常，这意味着你在 Android 不允许的 UI 线程上进行网络调用。查看文档，很简单。

    String requestId = MediaManager.get().upload("imageFile.jpg")
   .unsigned("sample_preset")
   .dispatch();
