on LGE LG D802 device, the camera app doesn't seem to recognise Emojify's File Provider and thus no photo is captured and displayed, for a work around, this line in MainActivity.java solved the problem for me:
Uri photoURI = Uri.fromFile(photoFile);
instead of Uri photoURI = FileProvider.getUriForFile(...);
