Android 进展中的loopj未按预期工作

从android应用程序上传带有loopj的文件时，我遇到了一个非常奇怪的onProgress行为。 我正在使用SyncHttpClient一个接一个地上传多个文件， 但是onPorgress总是被一些看起来像硬编码或固定数字的数字触发，而不是二进制资产和已上载字节的实际大小。 下面是我得到的示例输出

V/AsyncHttpResponseHandler﹕ Progress 3353492 from 3353528 (100%)
V/AsyncHttpResponseHandler﹕ Progress 3353528 from 3353528 (100%)
V/AsyncHttpResponseHandler﹕ Progress 1338 from 2417 (55%)
V/AsyncHttpResponseHandler﹕ Progress 2417 from 2417 (100%)

然后，对于上传的每个文件，都会发生相同的调用顺序。任何想法都将不胜感激。顺便说一句，文件上传很好，我只是不能让负载指示器正常工作

以下是代码示例：

    @Override
    protected void onCreate(Bundle savedInstanceState) {
...
        waveOperation = new WaveOperation();
        waveOperation.execute();

    }
//inner asynchTask class
    private class WaveOperation extends AsyncTask<Void, Object, String> {

        @Override
        protected String doInBackground(Void... arg0) {
            waveAll(ApplicationContextProvider.getContext());
            return "Executed";
        }

        @Override
        protected void onPostExecute(String result) {
        }

        @Override
        protected void onPreExecute() {
        }


        private void waveAll(Context context) {
            String[] projection = new String[]{
                    MediaStore.Images.ImageColumns._ID,
                    MediaStore.Images.ImageColumns.DATA,
                    MediaStore.Images.ImageColumns.BUCKET_DISPLAY_NAME,
                    MediaStore.Images.ImageColumns.DATE_TAKEN,
                    MediaStore.Images.ImageColumns.MIME_TYPE,
                    MediaStore.Images.ImageColumns.ORIENTATION
            };

            String selection = MediaStore.Images.Media.DATE_TAKEN + " > ?";
            String[] selectionArgs = {String.valueOf(ApplicationContextProvider.getCurrentAssetDateTime().getTime())};
            final Cursor cursor = context.getContentResolver()
                    .query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, projection, selection,
                            selectionArgs, MediaStore.Images.ImageColumns.DATE_TAKEN + " ASC");

            while (cursor.moveToNext() && !isCancelled()) {
                final String imageLocation = cursor.getString(1);
                File imageFile = new File(imageLocation);
                if (imageFile.exists()) {   // is there a better way to do this?

                    Bitmap bm = BitmapFactory.decodeFile(imageLocation);
                    int orientation = cursor.getInt(5);

//                    Log.d("###################### orientation: ", String.valueOf(orientation));
                    long timeTaken = cursor.getLong(3);
                    final String dateTaken = simpleDateFormat.format(timeTaken);
...
                    Matrix matrix = new Matrix();
                    matrix.postRotate(orientation);

                    bm = Bitmap.createBitmap(bm, 0, 0, bm.getWidth(), bm.getHeight(), matrix, true); // rotating bitmap
                    final ByteArrayOutputStream stream = new ByteArrayOutputStream();
                    bm.compress(Bitmap.CompressFormat.JPEG, 100, stream);

                    try {
                        EWImage.uploadPhoto(stream.toByteArray(), dateTaken + ".jpg", new AsyncHttpResponseHandler() {
//this is the method that is not being fired often enough during the upload
//and when it's called, it report some weird numbers that look always the same regardles
//of file being uploaded
                                    @Override
                                    public void onProgress(int bytesWritten, int totalSize) {
                                        super.onProgress(bytesWritten, totalSize);
                                        Log.d("--------------progress: ", String.valueOf(bytesWritten) + " of " + String.valueOf(totalSize));
                                    }


                                    @Override
                                    public void onStart() {
                                        super.onStart();
...
                                    }

                                    @Override
                                    public void onSuccess(int statusCode, Header[] headers, byte[] responseBody) {
...
                                    }

                                    @Override
                                    public void onFailure(int statusCode, Header[] headers, byte[] responseBody, Throwable error) {
...
                                    }


                                    @Override
                                    public void onFinish() {
                                        super.onFinish();
                                    }
                                }
                        );
                    } catch (FileNotFoundException e) {
                        Log.e("FileNotFound", e.toString());
                        e.printStackTrace();
                    }



                }
            }

        }

    }

以及在基类中定义如下的SYNC_HTTP_客户端：

protected final static SyncHttpClient SYNC_HTTP_CLIENT = new SyncHttpClient();

static {
    PersistentCookieStore cookieStore = new PersistentCookieStore(ApplicationContextProvider.getContext());
    SYNC_HTTP_CLIENT.setCookieStore(cookieStore);

}

我确实弄明白了，

它只适用于File参数，不适用于Stream或ByteArray——似乎是loopj中的一个bug。

如果检查AsyncHttpResponseHandler的源代码，您会注意到在获得请求响应时也会调用“sendProgressMessage”。这就是您看到的最后两次更新：

V/AsyncHttpResponseHandler﹕ Progress 1338 from 2417 (55%)    
V/AsyncHttpResponseHandler﹕ Progress 2417 from 2417 (100%)

关于第一次更新：

V/AsyncHttpResponseHandler﹕ Progress 3353492 from 3353528 (100%)
V/AsyncHttpResponseHandler﹕ Progress 3353528 from 3353528 (100%)

---

请记住，totalSize中可能还考虑了任何请求头。

如果您只想打印文件大小，那么为什么不在onSuccess中打印文件大小？发布几部分代码我不想打印文件大小，而是在上传时打印上传进度。发布您的部分代码。在没有看到代码的情况下，我们无法提供任何建议，您可以在onSuccess（）中打印您想要的内容。刚刚用代码示例更新了原始帖子。这个问题解决了吗？同样的问题是

totalSize

始终为1

V/AsyncHttpResponseHandler﹕ Progress 3353492 from 3353528 (100%)
V/AsyncHttpResponseHandler﹕ Progress 3353528 from 3353528 (100%)
