> produce relatively small binaries for simple applications

The problem is that you need to have a huge Java runtime installed or use something like Jlink which still produces very large binaries for GUI apps.

I think wxWidgets is the Lazarus alternative that is the closest to what grandparent was asking for.

Is there something similar for Android as well?

Asking ChatGPT, it has made recommendations for Haxe most importantly, which claims to support a large number of platforms.

On Android, Java running on top of the Android Runtime is the native framework for apps.
