Until B4A version 8.0 this code was working, now it is failing. I am calling services with intent, defining them in a code module called MTO like this:
The service start and service cancel is called from another service called MTO_Run:
This was working, but under version 8.0, the StartServiceAtExact fails with the following logs:
The CancelScheduledService code fails with these logs:
Looking for ideas on what is happening - what has changed that prevents this code from working now when it was working in previous versions. Not sure if it is specifically B4A v8 where the change occurred, I don't recompile code after every release of B4A.
B4X:
Sub Process_Globals
'These global variables will be declared once when the application starts.
'These variables can be accessed from all modules.
' Dimension all the intents here:

' Initialize settings

inMTO_Run_EndFromMain.SetComponent("tbci.movie_timeout/.mto_run")The service start and service cancel is called from another service called MTO_Run:
B4X:
