🐛 Android build fails with Kotlin 2.x / RN 0.81 due to currentActivity and mutable map return types

[fathinafiff]

Description

Android build fails when using @100mslive/react-native-hms with modern React Native and Expo setups
(RN 0.81+, Expo SDK 54, Kotlin 2.1.x).

The failure happens during :compileDebugKotlin.

Errors

• Return type mismatch: expected MutableMap, actual Map
• Unresolved reference: currentActivity

Example errors:

Return type mismatch: expected 'MutableMap<String, Any>?', actual 'Map<String, Any>'
Unresolved reference: currentActivity

Root cause

1. Kotlin 2.x is stricter and does not allow returning immutable Map where React Native
   ViewManager APIs expect MutableMap.
2. currentActivity synthetic access is no longer available or deprecated in newer
   Kotlin / RN plugin versions. The recommended access is via
   reactApplicationContext.currentActivity.

Proposed fix

1) Return mutable maps

MapBuilder.of(
  ...
).build().toMutableMap()

2) Replace currentActivity access

reactApplicationContext.currentActivity

Tested with

• Expo SDK 54
• React Native 0.81.5
• Kotlin 2.1.x
• Android Gradle Plugin via Expo

Notes

This change is backward compatible with older RN versions and fixes build failures
for modern Expo / RN setups.

100ms React Native Version

@100mslive/react-native-hms@1.12.0

React Native Version

react-native@0.81.5 (Expo SDK 54)

Steps to reproduce

1. Create a new Expo SDK 54 project (or any RN 0.81.x project).
2. Install dependency:
   • yarn add @100mslive/react-native-hms@1.12.0
3. Prebuild / run Android:
   • npx expo run:android
     (or cd android && ./gradlew assembleDebug)
4. Build fails at :100mslive_react-native-hms:compileDebugKotlin with Kotlin compilation errors.

Expected results

Android build should succeed on modern React Native / Expo toolchains (RN 0.81.x, Expo SDK 54) without Kotlin compilation errors.

Code example, screenshot, or link to a repository

I can't share the full app repo, but this reproduces in a fresh Expo SDK 54 project by only installing @100mslive/react-native-hms@1.12.0 and running npx expo run:android.

Logs

[ExpoRootProject] Using the following versions:

• compileSdk: 36
• targetSdk: 36
• ndk: 27.1.12297006
• kotlin: 2.1.20

Extra Note:
This appears to be Kotlin 2.x / RN 0.81 compatibility. Using reactApplicationContext.currentActivity and returning toMutableMap() resolves the build.

@sapta100ms can you check this issue?

[geraldcells18]

Please do some fixes, we need to make this run on Android.

[sapta100ms]

Hello @geraldcells18 . I am from the 100ms team. We have taken this up and will soon get back with the fix.

[sapta100ms]

Hi @geraldcells18 We have published latest react-native-hms and react-native-roomkit versions 1.12.1 and 1.3.1 with the fixes above. Can you please try them and notify us if these resolves the issue?
Thanks for your patience!

[geraldcells18]

Will check, thank you
