build_signed_apk.md

Define 4 environment variables in build and add keyfile to designated path

• $KEYFILE: Path to signing key, should be absolute path
• $STORE_PASSWORD: Keystore password
• $KEY_ALIAS: alias, as the name stated (default "androidkey")
• $KEY_PASSWORD: password for key

Then in deployment for release APK, execute this command:

gradlew :app:assembleRelease \
    -Pandroid.injected.signing.store.file=$KEYFILE \
    -Pandroid.injected.signing.store.password=$STORE_PASSWORD \
    -Pandroid.injected.signing.key.alias=$KEY_ALIAS \
    -Pandroid.injected.signing.key.password=$KEY_PASSWORD

Or to build bundle

gradlew :app:bundleRelease \
    -Pandroid.injected.signing.store.file=$KEYFILE \
    -Pandroid.injected.signing.store.password=$STORE_PASSWORD \
    -Pandroid.injected.signing.key.alias=$KEY_ALIAS \
    -Pandroid.injected.signing.key.password=$KEY_PASSWORD
