Extensions and "The Quiz Alternative"
Extensions
If it feels like MIT App Inventor has limited options compared to apps you may use all the time, you need to know about "Extensions". The Android community has created lots of code that you can easily add to your app, granting it additional functions. There are a few trusted websites where they can be found, including PuraVida.
The AnimatedGradient extension you see working on the left was discovered by Brandon Zamora - it's super-easy to set up and would be a really nice touch for anyone's app. This method is great for a "Magic" button on PaintPot but works on backgrounds and arrangements as well!

This video is posted first because it's really all you need to make the magic happen. Download the extension file, add it to your project and then add it to the Design as a non-visible component first.

I do show how to download and activate the extension, but this video is mostly showing how I built a little test app so you could see the gradients that are at the end of the video above.

The images for our quiz need to be optimized for use in our Android App. If we make them no more than 400 pixels tall and choose a JPG compression quality setting to reduce the file size we can fit 10+ images into the app without overloading it. For more than 10 you'll need to make them even smaller!
