+## Publication Android (Play Store)
+
+Générer l'App Bundle signé :
+
+```bash
+./gradlew :androidApp:bundleRelease   # androidApp/build/outputs/bundle/release/androidApp-release.aab
+```
+
+La signature release lit `androidApp/keystore.properties` (gitigné) avec les clés
+`storeFile`, `storePassword`, `keyAlias`, `keyPassword`. Sans ce fichier, le build
+release échoue (volontairement) et seuls les builds debug restent possibles.
+
+La keystore `androidApp/livrets-release.keystore` sert de clé d'upload Play :
+**la sauvegarder** (avec `keystore.properties`), sinon plus de mises à jour possibles.
+À chaque release : incrémenter `versionCode` dans `androidApp/build.gradle.kts`.
