This document describes the process of releasing a new software version to the Android Store. Adapted from source.

Prerequisites

Release Key

cd android/app

Generate a release key called next-train-ct-release-key.keystore with an alias called next-train-ct-key-alias.

keytool -genkey -v -keystore next-train-ct-release-key.keystore -alias next-train-ct-key-alias -keyalg RSA -keysize 2048 -validity 10000

Ensure it is not being tracked by version control.

Save it somewhere secure.
