How to enable signals while Android app is in background
-
Hello,
I am trying to integrate VoIP Push Notifications in my app, so I can handle incoming connections. However, while the app is not in the foreground I cannot process any signals with Qt. It seems as if all signals emitted through queued connections are dropped (direct connections work, but are useless because Firebase runs in a different thread). Is there any way to temporarily activate regular signal processing while in background?
Thanks a lot.

@Andreas-E. I think you will need to implement a background service. Not active applications are stopped, so event loop is stopped.

Thank you, using a service came to my mind, but would be quite difficult to integrate. Currently I am using
<meta-data android:name="android.app.background_running" android:value="true"/>in the Android manifest which keeps the event loop running in background.

hi @Andreas-E.
you should investigate that further, because from my experience, all apps without background service eventually get suspended from non rooted devices.That includes apps with the manifest change
<meta-data android:name="android.app.background_running" android:value="true"/>
with this change, it will just take longer until the app becomes suspended

Hi @J-Hilk
I only need background operation for a short time after receiving an FCM data notification. I would expect the app to be woken up by the system in this case? But I'm still not sure if this will also wake up the event loop.
