Hello,
You could try with a Transparent Main activity which hides itself on Resume
Or a Widget service too but the user should put it on its Home to start it

Thanks, but it sounds a bit like a workaround. :/ Is it impossible to do something like that 'the right way' in b4a?
Does b4a only support ui apps?


How can I achieve that the main activity is transparent?

You don't need a transparent activity. You can use a service and set StartAtBoot to true.

However there must be an activity in your app and the user must start it at least once. This is how Android works (in newer versions of Android).

So with those flags, I only have to start it once to register the scheduler and afterwards the service starts itself without calling the main activity again? Even after reboots and without showing the main activity ? (otherwise I would have to hit back every time...)

Practically yes. Applications must be started explicitly by the user before they can start automatically.
