+# OpenNOW Native Android
+
+This folder is a standalone Android Studio project for the native Kotlin / Jetpack Compose OpenNOW target.
+
+Open it from Android Studio with **File > Open > `OpenNOW/android`**. Android Studio will install/use the required Gradle, Android SDK, CMake, and NDK components from the project configuration.
+
+## Build Targets
+
+- `:app:assembleDebug` builds a debug APK.
+- `:app:assembleRelease` builds a release APK after signing config is added locally.
+
+## Runtime Notes
+
+- UI is native Compose.
+- GFN auth, catalog, subscription, CloudMatch session creation/polling/claim/stop, signaling, and input packet behavior are implemented in Kotlin from the Electron project contracts.
+- Streaming uses Android WebRTC plus hardware MediaCodec probing. The bundled `opennow_native` JNI library exposes native runtime diagnostics and keeps the NDK/CMake path wired for media-sensitive code.
+- Queue ad metadata is preserved in `SessionInfo`; ad playback can use the included Media3 dependency when the server returns an ad media URL.
