TypeError: Cannot read property 'sdkVersion' of undefined on emit in Nativescript

Question

I'm trying to implement Nativescript-Webview-Interface. In my case, everything is working fine on the IOS emulator, but getting an error on the Android when emit/callJSFunction from Native app to Webview.

chromium: [WARNING:dns_config_service_posix.cc(342)] Failed to read DnsConfig.
System.err: An uncaught Exception occurred on "main" thread.
System.err: Calling js method onTouch failed
System.err: TypeError: Cannot read property 'sdkVersion' of undefined

Answer 1

you are probably using updated version of nativescript but outdated version of nativescript-webview-interface just like me. We have solve this by

tns plugin update nativescript-webview-interface

then delete this file or you will have permission denied error

app\build\intermediates\signing_config\debug\out\signing-config.json
