I faced a bug while making this application. I wrote the entire code and my application was running but nothing was rendering on the Flixster screen. After reviewing some online resources like Udemy and stackovreflow, I found out that my activity_main.xml file had an issue. In this file, I did not set the android layout_width and android layout_height to "match parent" instead they were set to 0dps. Once, I corrected this issue my application ran fine.
