Unfortunately this currently works for me.
- In Worklight 6.0.0.1 I've created a new Worklight project and application with the Android environment, built and deployed it
- I then exported the Worklight project as a .zip file
- In Worklight 6.1.0 I've imported the above .zipped project, built and deployed it
- Ran the generated Android project in the Android emulator
This was with a blank new app; it's possible yours is more intricate than that.
Suggestions:
- Delete the native folder and re-build and deploy.
- Make sure to back-up any native Java classes and other artifacts you may have previously added to the native folder.
- Provide your Worklight project (the original from 6.0.0.x) in a Dropbox download link for analysis...
