yeah I get this exact error too, something is broken. I am unfamiliar with android and dont know how its toolchain works and interacts with this library or react-native. I will research it and if I find something I will post here

i cant fix it , its very hard ,becouse in java or other sourse code has bug,in project first level index.js function start call a import to react-native module NativeModules,NativeModules value is null object,than function start call it,it report error

[olivier-nerot]

I have the same error here (Mac OS 12, node 22.13.0)
To reproduce it :

npx @react-native-community/cli init
cd myApp
npm install nodejs-mobile-react-native --save
(*)
npm run android

(*) setup steps given here
it returns :

I've also tried to launch the app with Android Studio (build 21.0.5+-12932927-b750.29 x86_64)

A solution or a workaround is welcome.

[olivier-nerot]

It looks like it the same issue than #78
And the workaround seems to work, by editing /android/gradle.properties :

# Use this property to specify which architecture you want to build.
# You can also override it from the CLI using
# ./gradlew <task> -PreactNativeArchitectures=x86_64
reactNativeArchitectures=armeabi-v7a,arm64-v8a,x86_64

# Use this property to enable support to the new architecture.
# This will allow you to use TurboModules and the Fabric render in
# your application. You should enable this flag either if you want
# to write custom TurboModules/Fabric components OR use libraries that
# are providing them.
newArchEnabled=false

@olivier-nerot thanks,i try it befor report the issue, maybe just my net work problem,i will retry it

[alexjyong]

Can confirm the newArchEnabled workaround works.
