[Thoughts]Programming musings thread[General]

Post little thoughts, jokes, news, etc. that don't necessarily warrant having their own thread.

On the topic of Java, I have a lot of experience making desktop Java software. How hard would it be to make Android apps in Java? I downloaded Android Studio but I've never really used it before.

Any recommendations for resources for learning Android app development through Java? Can you even still submit Java apps to Google Play, or is it Kotlin-only now?
