build-love-android

CI build environments for the Android version of LOVE. The tag indicates what version can be built and what is included.

Examples with env

An env tag only provides the build environment.

Building in shell

export LOVE_VER=11.4

git clone --recursive -b $LOVE_VER https://github.com/love2d/love-android
cd love-android
docker run -i -t --rm \
	-v $(pwd):/prj -w /prj \
	-v ./outputs:/love-android/app/build/outputs \
	ioribranford/build-love-android:$LOVE_VER-env \
	./gradlew assembleNormalRecord

Building in GitLab CI

build-android:
        stage: build
        image: ioribranford/build-love-android:11.4-env
        script:
                - git clone --recursive -b "11.4" https://github.com/love2d/love-android
                - cd love-android
                - ./gradlew assembleNormalRecord bundleNormalRecord
        artifacts:
                name: "${CI_PROJECT_NAME}-${CI_COMMIT_REF_NAME}-android"
                paths:
                        - "app/build/outputs/apk"
                        - "app/build/outputs/bundle"

Editing AndroidManifest

xmlstarlet is included.

export GAME_TITLE="My Lovely Game"

xmlstarlet ed -L \
  -u "/manifest/application/@android:label" -v "$GAME_TITLE" \
  -u "/manifest/application/activity/@android:label" -v "$GAME_TITLE" \
  app/src/main/AndroidManifest.xml

Full example

Following instructions from love-android wiki https://github.com/love2d/love-android/wiki/Game-Packaging

export LOVE_VER=11.4
export GAME_DIR="./game"
export GAME_ID=com.example.mygame
export VERSION_CODE=1
export VERSION_NAME=1.0
export GAME_TITLE="My Lovely Game"
export ICON_DIR="./androidicons"
export ICON_ID="@mipmap/ic_launcher"
export KEYSTORE="keystore.jks"
# define secret KEYSTORE_ALIAS and KEYSTORE_PASSWORD elsewhere

git clone --recursive -b $LOVE_VER https://github.com/love2d/love-android
cd love-android

# package the apk with your own LÖVE game
mkdir -p app/src/embed/assets
cp -R "$GAME_PATH"/* app/src/embed/assets

# give your package a unique name, change the version
sed -i -r \
  -e "s/applicationId .+/applicationId '$GAME_ID'/" \
  -e "s/versionCode .+/versionCode $VERSION_CODE/" \
  -e "s/versionName .+/versionName '$VERSION_NAME'/" \
  app/build.gradle

# change the name
xmlstarlet ed -L \
  -u "/manifest/application/@android:label" -v "$GAME_TITLE" \
  -u "/manifest/application/activity/@android:label" -v "$GAME_TITLE" \
  app/src/main/AndroidManifest.xml

# change the icon
cp -R $ICONS_DIR/* app/src/main/res
xmlstarlet ed -L \
  -u "/manifest/application/@android:icon" -v "$ICON_ID" \
  app/src/main/AndroidManifest.xml

# build
./gradlew assembleEmbedRecordRelease bundleEmbedRecordRelease

# sign apk and bundle if release
apksigner sign --ks "$KEYSTORE" \
  --ks-key-alias $KEYSTORE_ALIAS \
  --ks-pass env:KEYSTORE_PASSWORD --key-pass env:KEYSTORE_PASSWORD \
  --out "${GAME_TITLE}.apk" \
  app/build/outputs/apk/embedRecord/release/app-embed-record-release-unsigned.apk
jarsigner -keystore "$KEYSTORE" \
  -storepass $KEYSTORE_PASSWORD \
  -signedjar "${GAME_TITLE}.aab" \
  app/build/outputs/bundle/embedRecordRelease/app-embed-record-release.aab \
  $KEYSTORE_ALIAS

# make debug symbols package
DEBUG_SYMBOLS_PATH=app/build/intermediates/merged_native_libs/embedRecordRelease/out/lib/
cp -r $DEBUG_SYMBOLS_PATH/* .
zip -r native-debug-symbols.zip $(ls $DEBUG_SYMBOLS_PATH)

Examples with full

A full tag includes a prebuilt love-android to eliminate initial compilation time.

Its default action is to customize the app according to env vars, build and sign all the release APKs and bundles, and make native debug symbol packages to include with your Play Store submission.

For these examples, assume an "env script" named buildenv.sh.

export LOVE_VER=11.4
export APPLICATION_ID=com.example.mygame
export VERSION_CODE=1
export VERSION_NAME=1.0
export GAME_TITLE="My Lovely Game"
export KEYSTORE_FILE="$PWD/keystore.jks"

export GAME_DIR="$PWD/game"
# where you keep main.lua, conf.lua, source files, data files...

export ICON="@mipmap/ic_launcher"
export ICONS_DIR="$PWD/androidicons"
# for $ICON, should contain mipmap-*/ic_launcher.png

The build tasks are assembleEmbedRecordRelease bundleEmbedRecordRelease assembleEmbedNoRecordRelease bundleEmbedNoRecordRelease. To run a different set of build tasks, define the following vars:

export PACKAGE_TYPES="assemble bundle"
export APP_TYPES="normal embed"
export RECORD_TYPES="record noRecord"
export BUILD_TYPES="debug release"

Build in shell

export KEYSTORE_ALIAS=KeystoreAlias
export KEYSTORE_PASSWORD=K3yst0rePa55w0rd

docker run --rm \
	-v $PWD:/prj -w $/prj \
	-v ./outputs:/love-android/app/build/outputs \
	-e KEYSTORE_ALIAS -e KEYSTORE_PASSWORD \
	ioribranford/build-love-android:11.4-full \
  sh -c '. ./buildenv.sh && cd /love-android && ./build-game.sh'
