A lightweight Niotron/App Inventor extension that renders animated GIFs directly inside a VerticalArrangement, using Android’s native Canvas (android.graphics.
Movie) instead of WebView. No HTML, no JavaScript, no external dependencies — just three blocks (Show, Stop, IsShowing) and you’re done. Compatible with any device from Android 7 onward.
I tested the version in App Inventor, and it works without any problems. I’m sharing the steps and blocks you need to use so you can run your own tests:
-
On the main screen, add a VerticalArrangement1 and set the dimensions to whatever you prefer.
-
Upload the GifAnimation extension.
-
Upload a GIF file to the Assets section.
-
In the GIF property, select the GIF you uploaded from the Designer view, or select it using the Blocks.
-
Go to the Blocks section.
-
Under Initialize, select the Show block and pass VerticalArrangement1 as the parameter.
Finally, update the project in the Companion. That’s all!
