Android Question Display data from class in an overlay window

[juve021]

I have data from a BLE device that captures data via a class module as in Erel's Heart rate monitor example (thanks eremes!). I can easily display the data in a regular activity label each time the data is changed however for the life of me, can't figure out how to display the activity as an overlay (transparent activity) window. I've found Informatix's pro bundle which has an overlay library and it is exactly what I want to do but can't seem to merge the two. The overlay library uses a service and I can't seem to get the data from the class into the service? I know this is probably a trivial question so excuse me if it is.

This is not trivial at all. It is difficult to draw over other apps and it requires special permission.

Thanks Erel. Is there a way to send data from a class module, like your HeartRateMonitor.bas example to a service to update a label. The Label is defined in a panel in the service.

Services can not have any Label or other UI Elements.
