ExpoFP

An Android library (AAR) to show and manage floor plans.

What's new in ExpoFP SDK version 5.10.0

  • Added planOperationalErrorFlow to receive errors that occur while the plan is operating, for example location provider failures.
  • Fixed a location provider failure replacing the plan loading status: provider errors are now delivered to planOperationalErrorFlow instead of planStatusFlow, so the plan keeps loading and remains usable. Collect planOperationalErrorFlow before attaching the plan view; if you handled these errors via planStatusFlow, switch to it.
  • Fixed a preloaded plan reused across screens leaving an earlier screen blank: getView() now returns a new lightweight host container on each call and shows the plan in the most recently attached host, automatically returning it to the previous screen when the current one is destroyed. Call getView() once per screen and do not compare results by identity or cache the view beyond the screen's lifetime; existing re-attachment workarounds keep working. getView() is now annotated @MainThread.
  • ExpoFpPlanPreloader.disposePreloadedPlan() and removeAllPreloadedPlans() can now be called from any thread and dispose each plan exactly once; presenter cleanup always runs on the main thread.
  • Fixed double encoding of URL parameters with special characters when loading a plan, which broke booth selection by name.
  • Removed ExpoFpPlanParameter.ServiceWorker; the floor plan does not read the sw parameter. Use ExpoFpPlanParameter.Raw("sw", "1") if you still need to send it.
