What is waitscreen?

WaitScreen is a small Android library that shows a loading overlay on top of a screen while your app is fetching data. Instead of leaving users staring at a blank or frozen page while a network request finishes, you get a simple masked popup that signals "something is happening." When a user opens a page that needs to load data from the internet, there's always a gap before that data arrives. This library fills that gap with a loading screen, a semi-transparent overlay with a loading indicator. It's built on top of Android's built-in PopupWindow component, which means it's a lightweight layer that sits on top of your existing page rather than replacing it. Once your data is ready, you dismiss the overlay and reveal the content underneath. This would be useful for Android developers building apps where pages frequently pull data from a server, think news feeds, product listings, or profile screens. Any time a user might otherwise wonder "did the app freeze?" or "is it doing anything?", a loading mask gives them immediate visual feedback that the app is working on it. The README is fairly minimal. It includes an animated demo gif showing the effect in action, and points readers to a sample project for actual usage instructions rather than spelling out the setup steps in writing. There's no mention of customization options, configuration details, or compatibility requirements, so you'd need to look at the demo code to get a full picture of what's possible.
