[Interest] Android services

[Jason H]

I am willing to write as much android code as I need That is to say I was hoping to extend QtActivity, and have the QtActivity talk to the service as if it were a proper Android app, as well as code the service in Android SDK. I have the luxury of being able to mostly coordinate things through the database (save for kicking off the service) so I think I should be ok. But MyActivity (extends QtActivity) does not seem to start the service, even with startIntent() (The service class, extending IntentService never even gets created!?)

> Yeah, we have the same challenge. Our current workaround is to launch our Activity as a sticky activity, and then push it to the background after it starts processing events. Hopefully, that keeps it invisible to device users at startup, but gets our service running in-process. It's an ugly hack, but we hope Qt can work on this or perhaps we can help by contributing eventually.
