This is not a fix but a workaround.
I had the same issue until I removed the “cordova-plugin-android-enumeratedevices” plugin.
The plugin is used to detect available devices (video/mic) so that you in the sample app can pick among the different devices.
I removed the plugin and so then I couldn’t pick a video or mic device/source, but the app picked up my default devices anyway so I could go ahead and try the sample app.
I was going to file an issue on github but I haven’t had time for it. Maybe our Android API’s aren’t installed locally or something like that…

Thank you, Richard I will try out your suggestion.

thank you. It’s working after removing the plugin. But i am not able to access the mobile device. Is there any solution where we don’t have to remove the “cordova-plugin-android-enumeratedevices” plugin. So we can access the devices like back camera
