Image rotates after bitmap.compress

Question

So i'm trying to get the user to pick an image from their photo gallery then upload it to Firebase Storage...so far my code looks as follows:

@Override
protected void onActivityResult(int requestCode,int resultcode, Intent data){
    super.onActivityResult(requestCode,resultcode,data);

    if(requestCode == REQUEST_IMAGE_CAPTURE && resultcode == RESULT_OK) {
        final Uri uri = data.getData();

        if (uri != null){
            Bitmap bmp = null;
            try {

                bmp = MediaStore.Images.Media.getBitmap(getContentResolver(), uri);

            } catch (IOException e){
                e.printStackTrace();
            }
            ByteArrayOutputStream baos = new ByteArrayOutputStream();
            bmp.compress(Bitmap.CompressFormat.PNG, 25, baos);



            byte[] fileInBytes = baos.toByteArray();
            bmp.recycle();
            FirebaseAuth auth = FirebaseAuth.getInstance();
            FirebaseStorage storage = FirebaseStorage.getInstance();
            String imageString = "";
            if(clickPhoto ==1){imageString = "Image 1"; }
            else if(clickPhoto ==2){imageString = "Image 2"; }
            else if (clickPhoto ==3){imageString = "Image 3"; }
            else if (clickPhoto ==4){imageString = "Image 4"; }
            final StorageReference storageReference = storage.getReference().child("Images").child("users").child(auth.getCurrentUser().getUid()).child(imageString);
            storageReference.putBytes(fileInBytes).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
                @Override
                public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
                    storageReference.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
                        @Override
                        public void onSuccess(Uri uri) {
                            String downloadUrl = uri.toString();
                            String urlString ="";
                            if(clickPhoto ==1){ urlString = "photo1URI";}
                            if(clickPhoto ==2){ urlString = "photo2URI";}
                            else if (clickPhoto ==3){ urlString = "photo3URI";}
                            else if (clickPhoto ==4){urlString = "photo4URI";}

                            toMap.put(urlString, downloadUrl);
                            updatedb();
                            toMap.clear();
                            Log.d("uriii",downloadUrl);}


                    });
                }
            }).addOnFailureListener(new OnFailureListener() {
                @Override
                public void onFailure(@NonNull Exception e) {
                    Log.d("UploadFailure",e.getMessage());
                }
            });




        }
        else {
            Toast.makeText(this,"Didn't work",Toast.LENGTH_LONG).show();
        }
    }
}

My problem is that the image that is uploaded changes orientation...seeminly at random....how do i maintain orientation? I've looked at Exif interface but can't see an answer for uploading it as a ByteArrayOutputStream?

Any help would be appreciated.

it doesn't solve my problem, as i still can't apply the exif interface to the bmp.compress(Bitmap.CompressFormat, quality, output) method? — James Palfrey, Jul 12 '18 at 16:51
Check the answer here by Manuel for how to apply the rotation to the bitmap https://stackoverflow.com/questions/3647993/android-bitmaps-loaded-from-gallery-are-rotated-in-imageview — mrmichaeldev, Jul 12 '18 at 17:05
It's not a case of applying it to the Bitmap, the Bitmap is compressed using bmp.compress and then output into a ByteArrayOutputStream before being uploaded into firebase....so i need to apply the rotation to the bytearrayoutput before it is uploaded? — James Palfrey, Jul 12 '18 at 18:46

Issue is that EXIF information from image (including orientation) is removed after compressing. You need to copy EXIF info from original image to compressed one. Solution explained here.
