I have used Watchfacewear in B4A12.00 and no problems.
However, when I load my program with B4A 12.50 I get the following error message.
What can I do?


Code: 
Sub Service_Create
    DigitalWFManager.Initialize("WF", 1000)
    JavaObject.InitializeContext
    ' Stellen Sie sicher, dass das B4A DateTime-Objekt Zeitänderungsereignisse erhält
    DateTime.ListenToExternalTimeChanges
Sub
beenden


Code: 
** Aktivität (Track) Lebenslauf **

I'm afraid that it look like Erel has removed a field called "isService" from the ProcessBA class, perhaps owing to the de-emphasis of services in preference to receivers. The "initialize" method of the WatchFace library checks this field when starting the WatchFaceService to check that it really is running in a service.

The bottom line is that without a modification this seven year old library is obsolete and now useless with current versions of B4A.
