Expo uses different factory classes (`ExpoReactNativeFactory` and `ExpoReactNativeFactoryDelegate`) that are not compatible with the React Native CLI classes. + +### Solution + +The solution implements **conditional compilation** using preprocessor definitions to switch between React Native and Expo classes at compile time. This approach: + +1. **Maintains the same API** - No changes required in JavaScript code +2. **Uses drop-in replacement** - Expo classes are used when `EXPO_MODULE` is defined +3. **Preserves functionality** - All sandbox features work in both environments +4. **Ensures compatibility** - Works with both React Native CLI and Expo projects + +## Implementation Details + +### 1.

On iOS, `routeMessage` checks `registry.isPermittedFrom()`. Additionally, `registerSandbox` is called with an empty `std::set()` for `allowedOrigins`, so even if the check were added, everything would be blocked. The allowed origins need to be read from the Kotlin delegate. + +### Breaking Changes +- **C-5. `BubblingEventHandler` changed to `DirectEventHandler`** + `specs/NativeSandboxReactNativeView.ts` — `onMessage` and `onError` changed event types.

If `cleanup()` is called off the UI thread, this is a data race. + +- **W-7. `registerSandbox` silently overwrites `allowedOrigins` for existing origin** + `SandboxRegistry.cpp` — A second registration with the same origin but different permissions overwrites the first delegate's permissions. Could be privilege escalation or denial. + +### JNI Correctness +- **W-3.

A pending Java exception propagates unpredictably. + +### API / Behavioral Correctness +- **W-5. `SandboxContextWrapper.getApplicationContext()` returns `this`** + `SandboxReactNativeDelegate.kt` — Returning the wrapper instead of the real `Application` causes `ClassCastException` when code does `context.applicationContext as Application`. + +- **W-6. `createBundleLoader` uses `createFileLoader` for HTTP URLs** + `SandboxReactNativeDelegate.kt` — `JSBundleLoader.createFileLoader` expects a local file path. May not handle HTTP URLs in all RN versions. + +- **W-8. `SandboxRegistry` is now 1:N but iOS still calls `unregister(origin)`** + `SandboxRegistry.cpp` — Registry changed from 1 to N delegates per origin, but iOS code still calls `unregister(origin)` which removes all delegates.
