I need a person for a simle android app developement. The app consists of picture and a button. When you press the button the picture will change. After installation a window will remind people to rate the app in Google play. The app will aslo include 2 SDK for advertising. I will provide a picture for the background, two pictures that will have to change when you push the button and a picture of the button itself. The final app should be ready to be uploaded to Google Play.
