Ok,add a / to engine gets sdk30.
I had removed the older suggestion to use
engine name=“android” spec=“10.1.0"
and instead used
<uses-sdk android:targetSdkVersion="30"/>
This works as well, still without engine name=“android” spec=“10.1.1”
Essential however was / is the line <content src="index.html" />
.
We’re testing an update to VoltBuilder which should help with this.
