上传到亚马逊服务器时图像方向已更改

Question

我正在将image上传到amazon server。一切运作良好，但只有少数设备orientation更改为landscape。在上传几个三星设备和平板电脑上的方向更改时。我试图解决它，但似乎没有任何工作。下面提到的是我的代码。

if (requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE) {

        if (resultCode == RESULT_OK) {

            value = true;

            viewPager.setVisibility(View.VISIBLE);

            Uri takenPhotoUri = getPhotoFileUri(photoFileName); //get the uri of the photo in order to get the path.
            System.out.println("URI==" + takenPhotoUri);
            al.add(takenPhotoUri);

            Bitmap takenImage = BitmapFactory.decodeFile(takenPhotoUri.getPath());


            final int maxSize = 1560;
            int outWidth, outHeight;
            int inWidth = takenImage.getWidth();
            int inHeight = takenImage.getHeight();
            if (inWidth > inHeight) {
                outHeight = maxSize;
                outWidth = (inHeight * maxSize) / inWidth;
            } else {
                outHeight = maxSize;
                outWidth = (inWidth * maxSize) / inHeight;
            }

            SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");


            takenImage = Bitmap.createScaledBitmap(takenImage, outWidth, outHeight, false);
            String newDate = sdf.format(new Date());

            Canvas canvas = new Canvas(takenImage); //bmp is the bitmap to dwaw into

            Paint paint = new Paint();
            paint.setColor(Color.RED);
            paint.setTextSize(30);
            paint.setTextAlign(Paint.Align.RIGHT);
            canvas.drawText(newDate, 200, 100, paint);

            //Creating a byte array output stream which is used to store the image once it has been compressed.
            ByteArrayOutputStream bos = new ByteArrayOutputStream();

            //Compress the image and store it in our ByteArrayOutPutStream
            takenImage.compress(Bitmap.CompressFormat.JPEG, 90, bos);

            int rotate = 0;
            try {

                getContentResolver().notifyChange(takenPhotoUri, null);
                File imageFile = new File(String.valueOf(al.get(0)));


                ExifInterface exif = new ExifInterface(
                        imageFile.getAbsolutePath());
                int orientation = exif.getAttributeInt(
                        ExifInterface.TAG_ORIENTATION,
                        ExifInterface.ORIENTATION_NORMAL);

                switch (orientation) {
                    case ExifInterface.ORIENTATION_ROTATE_270:
                        rotate = 270;
                        break;
                    case ExifInterface.ORIENTATION_ROTATE_180:
                        rotate = 180;
                        break;
                    case ExifInterface.ORIENTATION_ROTATE_90:
                        rotate = 90;
                        break;
                }

                Matrix matrix = new Matrix();
                matrix.postRotate(rotate);

            } catch (Exception e) {
                e.printStackTrace();
            }


            try {
                s3Client = new AmazonS3Client(
                        new BasicAWSCredentials(MY_ACCESS_KEY_ID, MY_SECRET_KEY));
                byte[] contentBytes = bos.toByteArray(); //Create a byte array to store the size of the stream.

                is = new ByteArrayInputStream(contentBytes);

                Long contentLength = Long.valueOf(contentBytes.length);

                objectMetadata = new ObjectMetadata();
                objectMetadata.setContentLength(contentLength);

                myAsyncTask = new MyAsyncTask();
                myAsyncTask.execute();

                responseUrl += s3Client.getResourceUrl(BUCKET_NAME, photoFileName) + " ";
                System.out.println("URL IS +==========" + responseUrl);


            } catch (Exception e) {
                e.printStackTrace();
            }


            //Add the path of the image to the array list and pass it to our custom adapter.
            bitmapArrayList.add(takenImage);


            imageSwipeAdapter = new ImageSwipeAdapter(this, iv, bitmapArrayList, viewPager, this, al,
                    viewPagerLayout, cameraBtn);
            viewPager.setAdapter(imageSwipeAdapter);


        } else {
            Toast.makeText(this, "Picture Wasn't taken!", Toast.LENGTH_SHORT).show();
        }

我的AsyncTask正在后台上传图片。
