Android Question Ideal Background Service Setup

[epiCode]

I am using B4XPages in my project.
There is a TTS module which is supposed to play even when screen is turned off.
It plays for a while then pauses and resumes only when screen is unlocked ( probably as long as tts queue is clear)
So after a lot of forum search - using a service seems to be the way to go
However I have a few questions, if experts here can help me with.

1. Will the service work with TTS the same way it does for playing audio ?
2. Do we move code for TTS play to service or just a new sub which keeps calling B4Xpages methods?
3. If service is started as Service.startForeground, How do we know when service actually resumes to foreground (phone unlocked/screen unlocked and app gets focus)
4. Do we destroy service every time the task is complete or only call service.StopForeground

1. You need to test it. I don't know.
2. No need to move the code if you are using B4XPages. You do need a foreground service and a PhoneWakeState lock.
3. B4XPage_Foreground event
4. No need to destroy the service.
