Question

我在他们的Mealspotting教程之后对我的代码进行了建模，但出于某种原因，我看不到保存在数据浏览器中的文件。这是为什么？这是我的代码：

private void saveScaledPhoto(byte[] data) {

        // Resize photo from camera byte array
        Bitmap snypImage = BitmapFactory.decodeByteArray(data, 0, data.length);
        Bitmap snypImageScaled = Bitmap.createScaledBitmap(snypImage, 200, 200
                * snypImage.getHeight() / snypImage.getWidth(), false);

        // Override Android default landscape orientation and save portrait
        Matrix matrix = new Matrix();
        matrix.postRotate(90);
        Bitmap rotatedScaledMealImage = Bitmap.createBitmap(snypImageScaled, 0,
                0, snypImageScaled.getWidth(), snypImageScaled.getHeight(),
                matrix, true);

        ByteArrayOutputStream bos = new ByteArrayOutputStream();
        rotatedScaledMealImage.compress(Bitmap.CompressFormat.JPEG, 100, bos);

        byte[] scaledData = bos.toByteArray();

        // Save the scaled image to Parse
        photoFile = new ParseFile("snyp.jpg", scaledData);
        photoFile.saveInBackground(new SaveCallback() {

            public void done(ParseException e) {
                if (e == null) {
                    ParseUser.getCurrentUser().put("photo",photoFile);
                    Log.d("save status",photoFile.getName() + " is saved!");
                } else {

                    Toast.makeText(getActivity(),
                            "Error saving: " + e.getMessage(),
                            Toast.LENGTH_LONG).show();
                }
            }
        });
    }

您只是忘记保存用户对象：ParseUser.getCurrentUser().saveEventually();

Parse.com文件保存Android无法正常工作
