Simple two screens Appcelerator App

A very simple project that will have following three screens 1. Splash screen: Just a simple image that stays for 5 secs and gone. 2. Dashboard: Dashboard will simply show some categories. user will tap on any category to enters its gallery to enters it. 3. Image gallery: Simple full screen images with nav dots. user will swipe left and right to change. User will have the ability to go back to Dashboard screen from the gallery. Functional Details: There should an arrays with all the category names, category main image and gallery image. The application should use that array to populate the Dashboard and gallery pages. Here is an example: categories=[] categories[0]={name: Trees, mainimage: [login to view URL], galleryimages=[[login to view URL],[login to view URL],[login to view URL]]} categories[1]={name: Flowers, mainimage: [login to view URL], galleryimages=[[login to view URL],[login to view URL],[login to view URL]]} Note: All these images i.e. [login to view URL], [login to view URL] 3.jpg... [login to view URL], [login to view URL] will be stored in local application directories. Important: It would like to fill that array later myself once I get the images. Application should follow Android material design. Please feel free to ask the questions to clear the scope. Thanks
