java - Android parse.com 无法上传文件

Question

我的应用程序半个月前运行良好，但现在我遇到了问题。我无法将图像上传到 parse.com 的某些表中。这仅在设备上出现问题，在模拟器应用程序上运行良好。我正在尝试此代码(从图库中选择图像):

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (resultCode == Activity.RESULT_OK && data != null) {
        String realPath;
        // SDK < API11
        if (Build.VERSION.SDK_INT < 11)
            realPath = RealPathUtil.getRealPathFromURI_BelowAPI11(this, data.getData());

            // SDK >= 11 && SDK < 19
        else if (Build.VERSION.SDK_INT < 19)
            realPath = RealPathUtil.getRealPathFromURI_API11to18(this, data.getData());

            // SDK > 19 (Android 4.4)
        else
            realPath = RealPathUtil.getRealPathFromURI_API19(this, data.getData());
        File file = new File(realPath);
        try {
            byte bytes[] = new byte[(int) file.length()];
            BufferedInputStream bf = new BufferedInputStream(new FileInputStream(file));
            bf.read(bytes, 0, bytes.length);
            bf.close();
            Bitmap bmp = BitmapFactory.decodeByteArray(bytes, 0, bytes.length);
            ((ImageView) findViewById(R.id.setIMG)).setImageBitmap(bmp);
            pFile = new ParseFile("file", bytes);
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

之后，当用户单击特殊按钮时，执行以下代码:

void sendPost(String txt) throws ParseException {
    String parseUserId = getIntent().getExtras().getString(ObjConst.OBJECT_ID);
    ParseUser parseUser = null;
    ParseQuery<ParseUser> queryUser = ParseUser.getQuery();
    queryUser.whereEqualTo(ObjConst.OBJECT_ID, parseUserId);
    try {
        parseUser = queryUser.getFirst();
    } catch (ParseException e) {
        Log.e("INTERNET", "Problem with internet connection or can`t find your accaunt.");
    }

    if (parseUser != null) {
        final ParseObject parseObject = new ParseObject(ObjConst.POST);
        parseObject.put(ObjConst.POST_ANONIMOUS, checkBox.isChecked());
        parseObject.put(ObjConst.POST_AUTHOR, parseUser);
        parseObject.put(ObjConst.POST_TEXT, txt);
        final Context ctx = this;
        if (pFile != null) {
            parseObject.put(ObjConst.POST_PHOTO, pFile);
            Log.d("MY_TAG", "Start upload.");
            pFile.saveInBackground(new SaveCallback() {
                @Override
                public void done(ParseException e) {
                    if (e != null) {
                        Log.d("MY_TAG", "ParseException: " + e.getMessage());
                    }
                    Log.d("MY_TAG", "Start save ParseObject");
                    saveParseObject(parseObject, ctx);
                }
            }, new ProgressCallback() {
                @Override
                public void done(Integer percentDone) {
                    Log.d("MY_TAG", percentDone+" %");
                }
            });
        } else saveParseObject(parseObject, ctx);
    }
}

void saveParseObject(ParseObject parseObject, final Context ctx) {
    Log.d("MY_TAG", "Start saveParseObject()");
    parseObject.saveInBackground(new SaveCallback() {
        @Override
        public void done(ParseException e) {
            Log.d("MY_TAG", e.getMessage());
            Log.d("MY_TAG", "End. ParseObject saved. " + e.getMessage());

            if (e != null)
                Log.i("Write post.", "Can`t write post. Problem with internet connection.");
            else Toast.makeText(ctx,
                    "Отправлено", Toast.LENGTH_SHORT).show();
        }
    });

}

程序的输出:

01-04 21:46:02.376 7360-7360/com.appserv D/MY_TAG: Start upload.
01-04 21:46:02.433 7360-7360/com.appserv D/MY_TAG: 58 %

这是什么？

尝试以这种方式将任何类型的图像成功上传到解析数据库中。

String first = "your image Path";
    final ParseFile Parseimagecam1;
    int targetW = 450;
    int targetH = 800;
    BitmapFactory.Options bmOptions = new BitmapFactory.Options();
    bmOptions.inJustDecodeBounds = true;
    BitmapFactory.decodeFile(first, bmOptions);
    int photoW = bmOptions.outWidth;
    int photoH = bmOptions.outHeight;
    // Determine how much to scale down the image
    int scaleFactor = Math.min(photoW / targetW, photoH / targetH);

    // Decode the image file into a Bitmap sized to fill the
    // View

    // imgHome.setImageBitmap(bitmap);

    bmOptions.inJustDecodeBounds = false;
    bmOptions.inSampleSize = scaleFactor << 1;
    bmOptions.inPurgeable = true;
    Bitmap bitmap = BitmapFactory.decodeFile(first, bmOptions);

    ByteArrayOutputStream stream = new ByteArrayOutputStream();
    bitmap.compress(Bitmap.CompressFormat.PNG, 100, stream);
    byte[] img1 = stream.toByteArray();
    String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss", Locale.getDefault()).format(new Date());
    Parseimagecam1 = new ParseFile("IMG_" + timeStamp + ".jpg", img1);
    Parseimagecam1.saveInBackground(new SaveCallback() {

        @Override
        public void done(ParseException e) {
            // TODO Auto-generated method stub
            if (e == null) {
                // success
                // here call your new method for upload image like
                uploadImage(Parseimagecam1);
            } else {
                // error
            }

        }
    });
}

protected void uploadImage(ParseFile parseimagecam1) {
    // TODO Auto-generated method stub
    final ParseObject parseObject = new ParseObject(ObjConst.POST);
    parseObject.put("keyName", parseimagecam1);
    parseObject.saveInBackground(new SaveCallback() {

        @Override
        public void done(ParseException e) {
            // TODO Auto-generated method stub
            if (e == null) {
                // success check your data base
            } else {
                // fail
            }

        }
    });
}

这对我来说已经完成了。我已在解析表中上传了最多 6 个图像。
