We would like to use Android Lollipop 5.1.1
But the guidance to any Android Version will help us for a proof of concept.
And about the package.
We are doing this for a demo purpose, so we are not using a installable package.
Just we need to show some sample package is deployed to a mobile app.(Some sample.txt will work for us with a sample lua script)
Can you help in this regard?
Have you tried out the Software Content Manager for deploying packages? Check out the help center for information on how to deploy packages and create assets. Here is the ThingWorx Utilities 7.1.0 Install Guide (be aware that the Software Content Manager and Remote Access and Control extensions will need to be imported separately, as described in that doc). Here is a KCS Article overview on the Asset Manager to help you get started.
Hope this helps!
