install

Signed migration candidates are available in GitHub Actions. Published builds are listed in releases.

Install the APK for your device over the corresponding OLCNG installation. Do not uninstall OLCNG first: its files are used for migration.

• regular APK: xyz.zarazaex.olc
• F-Droid APK: xyz.zarazaex.olc.fdroid

Both keep the existing signing key. The displayed name changes to oweng; application IDs stay unchanged so Android can install it as an update. Old MMKV files are retained during migration.

To build, install JDK 25, Go 1.27.3+, gomobile and gobind, Android SDK Platform 37.2, Build-Tools 37.0.0 and NDK r29:

git clone https://github.com/openlibrecommunity/olcng
cd olcng
export ANDROID_HOME=/path/to/android-sdk
export ANDROID_NDK_HOME="$ANDROID_HOME/ndk/29.0.14206865"
printf 'sdk.dir=%s\n' "$ANDROID_HOME" > local.properties
./run lib core
./bin/lib/naive/download.sh
./gradlew :app:downloadAssets
./gradlew :app:assembleOssRelease :app:assembleFdroidRelease

Local signing uses KEYSTORE_PATH, KEYSTORE_PASSWORD, KEY_ALIAS and KEY_PASSWORD. CI uses the existing APP_KEYSTORE_* secrets.

usage

Open the shared list, run a connection test, select a working profile and connect. The group screen also supports personal subscriptions and profiles.

The first launch explains the change from OLCNG in Russian. Subscription updates retain cached results when a source is unavailable.
