Play: version code has already been used

What this error means

Every upload to Google Play needs a higher versionCode than any build Play has seen, in every track.

Why it happens

Google Play keeps every versionCode that was ever uploaded, on every track. Reusing one is rejected even if that earlier release was discarded.

The message tools print

Google Api Error: Invalid request - Version code 12 has already been used.

How to fix it

1. Raise versionCode in android/app/build.gradle and build again.
2. Automate it from the latest code on Play. CapWrapp bumps it on every ship.
