>Being able to share UI and code on Android and iOS is still a desire for many developers. As hinted throughout the post, I think React Native may be the only other possible contender.

I have been a codenameone developer for 8 years now. On Android you run java and on ios you run static c which comes from the java code itself

Shai Almog and Steve Hannah have done a great job at making cn1 a comprehensible platform to develop on mobile. All the issues listed on this post are covered (scrolling with inertia, Android file system updates, etc)

I don't know how successful cn1 is in terms of users but I wish it were more popular on places like HN where React Native/Flutter is the bread and butter
