As a UBIK Android user, I want the app to keep track of (eventually) changing properties and tell me the reliability of the displayed value. These properties update themselfes repeatedly within a configured timespan. In addition, various information about freshness, measurement quality and synchronization to the client are available to the user.
Android Client
Live value properties may be displayed either within the content browser as property and / or within the map view upon selecting the regarding object.
Content Browser
The row for live value properties differs only slightly from normal property rows. On the left of the property value unter the description is an connectivity indicating icon, which looks like the connectivity icon from cell phones. The "Fresher" the property value is, the better connectivity is indicated. If all bars are greyed out and a small red cross is shown, the last update was either very long ago or no update was received at all. For detailed information about that, the detail dialog is necessary.
The freshness indicator has the following states, from left to right:
- New
- Outdated
- Old
The following gallery gives an overview about the possible synchronization states of live value property rows.
Fresh live values
Slightly outdated live values
Old live values
