Android development in 2023

Android Studio still supports Java, so if you want to work on an old Android Application you can still build (and modify) it as Java source.

As everyone knows, Java sucks. Kotlin is a much nicer and modern language, so I feel a strong pull to do any new work using Kotlin and ultimately to convert my old application code to Kotlin. I was at first alarmed by the change, but now I fully understand and embrace it.

Just recently I described Java coding as being like "scrubbing latrines in a Gulag". Given that sort of imagery, I would describe Kotlin as "a fun day skiing with friends".

I first began doing Android development back in 2012 using Java and ADT. I revisited things in 2017 using the same tools to make some changes to my application. Now in 2022, my copy of ADT no longer runs. This has forced me to look at updating my development tools and I find that there have been many changes.

• Installing Android Studio (Flamingo)
• Android Studio - first steps (broken tutorial)
• SDK and virtual devices

• Books!

• My pixel 6 phone
• Android versions
• Where is ADB ?

• Book: build android apps

• Easy Kotlin tutorial - a simple quiz (broken)
• Jetpack Compose Tutorial
• Jetpack Compose trial and error
• Jetpack Compose and state

• Where can I write files ?
• How can I read files ?
• What about internal files ?

• Calling a delay function from Kotlin

• Android "MAD" (modern Android development)

• Links and thing to watch and read someday

Kotlin on Fedora - Kotlin/native -- the Kotline language

This took me in directions I hadn't expected (in particular Kotlin/native). My notes on all of this is here, along with general notes about the Kotlin language that are Android agnostic.
