Build an android app for a php/mysql based download portal

Hello, We need an android app for one of our client's existing download portals essentially based on php/mysql. The android app will have to list data items from the portal's server via php/mysql and based on that further operations will be performed. The user should be able to download the content within the app itself and they should be able to resume or pause their downloads. Please note the app we need should not be a wrapper of the websites. Reference App: Vidmate ([login to view URL]) [This is just a reference app, in actual our app will be a lot different] All the work has to be done by the developer like making php/mysql api calls to and from the app to the server, creating graphics and design elements. Ads will also have to be placed in the app at desired locations. The Design and Quality of the app should be top notch. We would need all the source codes, Graphics and design elements after the completion of the project.
