[Android Native] Imitate a simple lock screen app

Overview 1. I'd like to make a Lock Screen app (an app that appears upon pressing lock button). Please see the attached picture. 2. There is a model app. Please see attached Excel file. The link to the model app can be found in 'Mockup1' tab. Requirements 1. The goal is to imitate the model app as closely as possible plus a little bit of my own idea. Please see the Excel file's 'Mockup1', 'Mockup2 with Data'. 2. I've also included a comprehensive list of features the app needs to have: see 'Feature List' tab. 3. The developer needs to document his/her code and organized the project with Git or Hg, so that the project can be maintained and updated. 4. I will provide icon & splash images. 5. Only a local storage is needed for now. If and when the app gets bigger, we might use web database/backend. Others - I have experience developing a hybrid mobile app two years ago. I've never developed a native app, but I am able to put myself in developers' shoes.
