TypeError: null is not an object 2 times - evaluating 'WebRTCModule.enumerateDevices' and evaluating 'WebRTCModule.getUserMedia'

[rexcode]

error 1 - TypeError: null is not an object (evaluating 'WebRTCModule.enumerateDevices')

error 2 - Possible Unhandled Promise Rejection (id: 4): TypeError: null is not an object (evaluating 'WebRTCModule.getUserMedia')

When I start call I get the above 2 errors

WebRTCModule is unavailable. Did you complete installation for Android/iOS by the React Native WebRTC guide?

[rexcode]

I have already installed react-native-connectycube so react-native-webrtc is already installed as a dependency correct ? or I have to install this separately ?

[ccvlad]

The RN WebRTC included as NPM module. But you should configure RN WebRTC for Android and iOS projects Guides:

• https://github.com/react-native-webrtc/react-native-webrtc/blob/master/Documentation/iOSInstallation.md
• https://github.com/react-native-webrtc/react-native-webrtc/blob/master/Documentation/AndroidInstallation.md

[rexcode]

I have done changes in configuration for Android - as given in the above link

I have made all changes for manual installation -

1. changes in settings.gradle
2. android/app/build.gradle
3. added missing permissions in androidmanifest.xml

But how I do make changes for MainApplicaiton.java as code there is different from what is given in instructions I do not understand Java

I have made the above stated 3 changes and tested again - still getting same 2 errors TypeError: null is not an object 2 times - evaluating 'WebRTCModule.enumerateDevices' and evaluating 'WebRTCModule.getUserMedia'

Please guide

[ccvlad]

Like as in example - packages.add(new WebRTCModulePackage())

[rexcode]

Hi, thanks for your quick reply

I have made change as given by you and added packages.add(new WebRTCModulePackage());

I have also added - packages.add(new com.oney.WebRTCModule.WebRTCModulePackage()); as inferred from react-native-webrtc documentation - shown below

but both times app build failed for first-line as given by you - the app does not build at all for second-line - my changes - app builds built fails on open and just crashes

my changes - commented out

Please guide do I need to install webrtc package manually again?

app packages used - "react-native": "0.63.2", "react-native-connectycube": "^3.12.0"

[ccvlad]

Add import com.oney.WebRTCModule.WebRTCModulePackage; at the top of MainApplicaiton.java file and use packages.add(new WebRTCModulePackage()).

Please try this.

Do you have some logs in Metro's console?

[rexcode]

I have made changes in MainApplication.java as you have given, app is building now but crashes on opening

There isn't crash info. Could you check logs via AndroidStudio?

1. Open AndroidStudio
2. Create or select any simple project
3. Choose 'Logcat'
4. Select your Android device
5. Select app

[rexcode]

Hi there,

searching logcat as instructed, was able to find this error

--------- beginning of crash

Thanks for all your help
