Because of the way non-Wasp devices are licensed, there is no way to use the Android or iOS app with a Demo installation of MobileAsset v7. It requires a paid license to be able to connect.
From the PC program, if you go to Help > Contents, you can look under Mobile Device Operation > Android Devices or iOS Devices for information about setting up and using the app, including screenshots.
However, you can use Wasp's demo server with sample data, in order to test the user interface on your device:
Service Url: http://mobileasset.waspbarcode.com:10008
Device name: specify anything here
