Submitted resume online. After that I was given a app coding challenge where you have to develop a full app. It says it takes 1-1.5 hours but it seems to be very low as the actual application takes a lot longer and involves networking with some random JSON format they use, adapters, activities, layouts, etc. I submitted mine after being tired of working on it for many hours to get it working and was rejected without any feedback on the app. Do not waste your time.
