Rewrite your Android app gradually, not all at once

Every two years development paradigm changes in Android. What was best practice is now legacy code. Most recently this paradigm shift was Jetpack Compose. Teams have a tendency to start from scratch and rewrite the app. It seems nice for the developers, but it always takes much longer than expected. And users are suffering - they are not getting updates for a long time. And when it's the time for a big release, users often react badly to too many changes at once. I recommend gradually transforming the codebase into a new paradigm. I led these transformation in multiple large apps and I will share lessons learned with you.
