MIT App Inventor is a great way to explore mobile application development for Android without needing to know how to code in Java or Kotlin. This is often referred to as "no-code" or "WYSIWYG" (what you see is what you get) programming.
The App Inventor uses Scratch blocks and a visual designer (not so dissimilar from Xcode's UI) to program the app.
However, the emulators provided by MIT aren't necessarily modern or full featured. There is a way around this though.
After building your app in MIT App Inventory, click Build
-> App ( save .apk to my computer )
to download an .apk
build of the app.
