android - Firebase storage upload progress inaccurate

Question

There is a problem with the onProgress function that is overrided by addOnProgressListener.

My problem is that the TaskSnapshot when I try to upload an image does not return the bytes that have been transferred. It just stays at 0. Here is a snippet of code that I have for this:

StorageReference myStorageRef = momentsStorageRef.child(momentID + ".jpeg");

UploadTask uploadTask = myStorageRef.putBytes(data, new StorageMetadata.Builder()
       .setContentType("image/jpeg")
       .build());



uploadTask.addOnProgressListener(new OnProgressListener<UploadTask.TaskSnapshot>() {
   @Override
   public void onProgress(UploadTask.TaskSnapshot taskSnapshot) {
       int bytesTransferred = (int) taskSnapshot.getBytesTransferred();
       int totalBytes = (int) taskSnapshot.getTotalByteCount();



       int progress = (100 *  bytesTransferred) / totalBytes ;
       Log.v(TAG, "Bytes transferred: " + taskSnapshot.getBytesTransferred());
       Log.v(TAG, "TotalBytes: " + totalBytes);
       Log.v(TAG, "Upload is: " + progress + "% done");
       mBuilder.setProgress(100, progress, false);


       mNotifyManager.notify(APPLICATION_NOTIFICATION_ID, mBuilder.build());
   }
})

Here is the logCat:
