Respect the device rotation lock on Android
3.8 KiB
Android (love-android 11.5a)
mobile/android/ is a vendored copy of
love2d/love-android at tag
11.5a (matches conf.lua t.version = "11.5"), tracked directly in
this repo, no git submodules involved. Nested love sources live at
mobile/android/love/src/jni/love (also vendored). Build outputs
(app/build/, love/build/, .gradle/, local.properties) stay
gitignored.
Refreshing the vendored tree
To pick up a newer love-android release, replace the tree and re-vendor:
rm -rf mobile/android
git clone --depth 1 --branch <new-tag> --recurse-submodules --shallow-submodules \
https://github.com/love2d/love-android.git mobile/android
rm -rf mobile/android/.git mobile/android/love/src/jni/love/.git \
mobile/android/.gitmodules
scripts/build_android.sh re-applies project branding on every run
(gradle.properties app id / name / portrait, plus permission trims), so a
refresh is safe, just rebuild.
Build
# Build the APK
scripts/build_android.sh
# Build the APK, setting app.version_name/app.version_code to match a release
scripts/build_android.sh --version 0.2.5
# Zip game.love + branding only (no Android SDK required)
scripts/build_android.sh --package-only
Or via scripts/build.sh android [--version X.Y.Z].
The embedded game.love deliberately excludes data/generated/,
assets/generated/, and any ROM. It contains the first-boot Lua importer and
tools/rom_manifest.json.
ROM / mod / save import on Android uses love.system.pickFile([kind]) →
GameActivity.showFilePicker (Storage Access Framework), which copies the
chosen file under the app save directory as picked_rom.gb,
picked_mod.zip, or picked_save.sav. RomImporter imports pending files
from that folder on Choose / refocus; see docs/launcher.md. The APK payload
itself remains data-free (no embedded ROM or generated cache).
SDK / NDK
love-android 11.5a expects:
- JDK 17
- Android SDK with API 34
- NDK 25.2.9519653 (Apple Silicon host supported)
Set ANDROID_SDK_ROOT (or ANDROID_HOME), or let the script write
local.properties when it finds ~/Library/Android/sdk.
Gradle flavor used: embedNoRecord (game fused into the APK, no microphone).
Build task: assembleEmbedNoRecordDebug.
The APK lands under app/build/outputs/apk/embedNoRecord/debug/.
scripts/build_android.sh also copies it to dist/android/debug/.
Payload path
app/src/embed/assets/game.love - zip of main.lua, conf.lua, src/,
data/, assets/, and the Red, Blue, and Yellow ROM manifests. The Android
packer verifies the Yellow manifest before it packages; if a partial source
export omitted it, it restores the file from this checkout's Git data and then
falls back to the project's GitHub copy. Generated game data,
scripts, tests, and mobile build sources are excluded.
Branding (applied by the build script)
| Setting | Value |
|---|---|
app.application_id |
com.theboisclub.pokemonred |
app.name |
Pokemon Red |
app.orientation |
fullUser. This is only the manifest default: SDL requests FULL_SENSOR at window creation (resizable window, no SDL_HINT_ORIENTATIONS), and GameActivity.setOrientationBis remaps that to FULL_USER so the device's rotation lock is honoured. |
app.version_name / app.version_code |
set from --version X.Y.Z (code = major10000 + minor100 + patch); left as-is if --version is omitted |
| Permissions | INTERNET / RECORD_AUDIO / WRITE_EXTERNAL_STORAGE stripped; VIBRATE + BLUETOOTH kept |
Releases
.github/workflows/release.yml builds the APK with --version set to the
release version and publishes it alongside the macOS/Windows/Linux builds as
PokemonRed-<version>-android.apk.
Signing
Signed with the default Android keystore (no setup required).
