+The following native files are generated automatically by `withMediaButtonModule.js` during `expo prebuild`:

+**iOS:**
+- `ios/ResgridUnit/MediaButtonModule.swift` - iOS native module using MPRemoteCommandCenter
+- `ios/ResgridUnit/MediaButtonModule.m` - Objective-C bridge file
+- Updates `ResgridUnit-Bridging-Header.h` with required React Native imports

+**Android:**
+- `android/app/src/main/java/{package}/MediaButtonModule.kt` - Android native module using MediaSession
+- `android/app/src/main/java/{package}/MediaButtonPackage.kt` - React Native package registration
+- Updates `MainApplication.kt` to register the MediaButtonPackage

+## Build Instructions
+
+Since this project uses Expo with prebuild, the native modules are generated automatically:
+
+```bash
+# Clean and regenerate native projects
+npx expo prebuild --clean
+
+# Or for specific platform
+npx expo prebuild --platform ios --clean
+npx expo prebuild --platform android --clean
+
+# Then build normally
+yarn ios  # or yarn android
+```
