Android app UI improvement

We are upgrading the Use Experience and User Interface from one of our Android apps (more than 7 millions of users). The new UX+UI will be heavily based on Google's Material Design guidelines. This project is the first one of a series of projects related to this complete app redesign, and will allow to select the most appropriate freelancer. The goal is to redevelop one specific "activity". Detailed specs will be provided and constant progress update will be needed. Very strong experience on Android UI development is required, including good knowledge of material Design and AppCompat library.
