I have a GPS/TTS (Flite) app that I would like to get working in the background. The app uses Flite to speak GPS values like speed. If I set the “Required background modes” to “App registers for location updates” (i.e. one of the three cases for background operation) then the GPS part of my app continues to work in the background, but Flite does not. Is there any way to get Flite to work in the background?
