安卓开发中 选择相册后剪切图片后得到的是 bitmap 如何转成File路径

OkHttpClient mOkHttpClient = new OkHttpClient();
        
        RequestBody requestBody = new MultipartBody.Builder()
                .setType(MultipartBody.FORM)
                .addFormDataPart("title", "wangshu")
                .addFormDataPart("image", "wangshu.jpg",
                        RequestBody.create(MEDIA_TYPE_PNG, new File("")))
                .build();

        Request request = new Request.Builder()
                .header("Authorization", "Client-ID " + "...")
                .url("http://wuliu.zhekd.com/index.php/Android/Me/upload")
                .post(requestBody)
                .build();

        mOkHttpClient.newCall(request).enqueue(new Callback() {
            @Override
            public void onFailure(okhttp3.Call call, IOException e) {
                Log.e("wangshu", "shibai");
            }

            @Override
            public void onResponse(okhttp3.Call call, Response response) throws IOException {
                Log.e("wangshul", response.body().string());
                Log.e("wangshu", "chengg");
            }

        });
