Release Guide

MCA release APKs should be published through GitHub Releases, not committed to the source tree.

Signing

Create a local signing.properties file from signing.properties.example. The file and keystore are ignored by Git.

Required keys:

storeFile=.signing/mca-release.jks
storePassword=...
keyAlias=mca-release
keyPassword=...

$env:JAVA_HOME='<path-to-jdk-17>'
$env:ANDROID_HOME='<path-to-android-sdk>'
.\gradlew.bat :app:assembleRelease -Pmca.abis=arm64-v8a

The APK is generated under:

app/build/outputs/apk/release/

Publish the APK and a SHA-256 checksum as a GitHub pre-release for alpha builds. Do not upload debug APKs as public installer packages.
