    Android TV 5 päivää left

    I am looking for a freelancer to create an Android TV app with a top navigation layout. I have specific colors and designs in mind for the app and would like the freelancer to incorporate them into the final product. The main purpose of the app is to stream live radio content. I have attached a layout file, where the top bar is for the navigation view. Once the user clicks on page1/page2 or so on then it will load the content of page1/page2 and so on respectively. Page1/page2 can contain RowSupportFragment or GridView. Right now you can use any demo data.

Content should load after clicking on the menu, not previously loaded. - Experience with Android TV app d...
