在 Android 中直接将捕获的图像上传到 Cloudinary

我想捕捉一张图片并直接上传到Cloudinary。我如何知道图片的名称以在上传声明中设置它cloudinary.uploader().upload("nameofthepic", Cloudinary.emptyMap());.

这是我的代码：

public class Camera extends ActionBarActivity implements View.OnClickListener {
    Button b;

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

        b= (Button) findViewById(R.id.button);
        b.setOnClickListener(this);

    }
    public static final int TAKE_PHOTO_REQUEST = 0;

    @Override
    public void onClick(View v) {
        Intent takePhotoIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        startActivityForResult(takePhotoIntent, TAKE_PHOTO_REQUEST);
        Map config = new HashMap();
        config.put("cloud_name", "dkepfkeuu");
        config.put("api_key", "552563677649679");
        config.put("api_secret", "7n8wJ42Hr_6nqZ4aOMDXjTIZ4P0");
        Cloudinary cloudinary = new Cloudinary(config);

        try {
            cloudinary.uploader().upload("", Cloudinary.emptyMap());
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
