С помощью API Android Camera привязанная ориентация фотографий всегда Undefined

Я использую камеру api, и сделанное фото всегда поворачивается на 90 градусов, и я хотел бы повернуть его.

Итак, прежде всего, я хотел бы знать ориентацию изображения, и этот момент я застрял. Я всегда получаю UNDEFDDED ориентацию в обоих направлениях.

Вот код:

    @Override
        public void onPictureTaken(byte[] data, Camera camera) {


            //Bitmap Options for lowering quality the bitmap to save memory
            Options options = new BitmapFactory.Options();
            options.inSampleSize = 4;
            options.inPreferredConfig = Bitmap.Config.RGB_565;

            //Make the bitmap
            Bitmap bitmap = BitmapFactory.decodeByteArray(data, 0, data.length, options);

            //Making the path, the root will be fine for tests
            String path = Environment.getExternalStorageDirectory().toString();

            //output stream
            OutputStream outputStream = null;
            //Making the file as a jpg
            File file = new File(path, "tmp_pic" + ".jpg"); // the File to save to
            try {

                //Writing the file
                outputStream = new FileOutputStream(file);
                outputStream.flush();
                outputStream.close(); // do not forget to close the stream


                //Getting the orientation in both possible ways
                int ori = getOrientationFromExif(file.getPath());
                int ori2 = getOrientationFromUri(Uri.fromFile(file));
            }
            catch (FileNotFoundException e) {
                e.printStackTrace();
            }
            catch (IOException e) {
                e.printStackTrace();
            }
            if (bitmap == null) {
                Toast.makeText(getApplicationContext(), "Error: Cant make photo.", Toast.LENGTH_SHORT).show();
            }
            else {
                PhotoTapView.photoViews.get(index).setPhotoImage(bitmap);
                finish();
            }
            cameraObject.release();
        }

Функции для ориентации:

    //Getting orientation from file URI
    private int getOrientationFromUri(Uri imageUri) {
    String[] orientationColumn = { MediaStore.Images.Media.ORIENTATION };
    Cursor cur = getContentResolver().query(imageUri, orientationColumn, null, null, null);
    int orientation = -1;
    if (cur != null && cur.moveToFirst()) {
        orientation = cur.getInt(cur.getColumnIndex(orientationColumn[0]));
    }
    Log.i("Orientation from Uri", orientation + "");
    return orientation;
}

    //Getting orientation from ExifInterface  
    private static int getOrientationFromExif(String imagePath) {
    int orientation = -1;
    try {
        ExifInterface exif = new ExifInterface(imagePath);
        int exifOrientation = exif.getAttributeInt(ExifInterface.TAG_ORIENTATION, ExifInterface.ORIENTATION_NORMAL);
        Log.i("Orientation from Exif: ", exifOrientation + "");
        switch (exifOrientation) {
            case ExifInterface.ORIENTATION_ROTATE_270:
                orientation = 270;
                Log.i("Orientation from Exif", "270");
            break;
            case ExifInterface.ORIENTATION_ROTATE_180:
                orientation = 180;
                Log.i("Orientation from Exif", "180");
            break;
            case ExifInterface.ORIENTATION_ROTATE_90:
                Log.i("Orientation from Exif", "90");
                orientation = 90;
            break;
            case ExifInterface.ORIENTATION_NORMAL:
                orientation = 0;
                Log.i("Orientation from Exif", "0 - Normal");
            break;
            case ExifInterface.ORIENTATION_UNDEFINED:
                orientation = -1;
                Log.e("Orientation from Exif", "UNDEFINED");
        }
    }
    catch (IOException e) {}
    return orientation;
}

Выход журнала:

01-14 19:46:09.468: E/Orientation from Exif(12411): UNDEFINED
01-14 19:46:09.468: I/Orientation from Uri(12411): -1

В чем может быть проблема?

outputStream = new FileOutputStream(file);
bitmap.compress(Bitmap.CompressFormat.JPEG, 90, outputStream);  // Add this line
outputStream.flush();
outputStream.close(); // do not forget to close the stream
