404115 Simple Google Android Joke App

I need an Android Joke Application. What I need: 1. When you start up the app, it should show categories of jokes. This page should be scroll view so that users can scroll up and down to choose a category. There might be a number of categories. 2. Each category of jokes will be in it's own xml file, so I can edit the jokes. 3. Once user clicks and chooses a category it will show the first joke. 4. Random Generator to pick random joke to display first. 5. User will click the "right" button to go to the next joke, or click on the "left" button to go back to the previous joke. They click on the "home" button to go back to the categories page. I uploaded a jpg picture that I made to show how the app should look.
