ANDROID: No longer receiving `EVENT_IDLE` for API26+

[mgorges]

While speaking of Android - with the recent move to API 26 the app does no longer receive EVENT_IDLE when the device is in doze mode. I.e., 10'' after switching the display off, there is no signal anymore. Background work stops.

Any knowledge or hint how to fix this?

Where did we move to API 26, the current minimum target is 21, and the Google Play store-required target is 28?

That's strange. Looks like I've been using API 26 for the past year already.

However since the recent changes to the build process, which now support arm64, the code working before does now no longer.

Mysterious.

The new default target is 28, if you drop that down to something lower some of the legacy pieces might kick in loaders/android/AndroidManifest.xml.in#L8. I know we used this trick initially when we had issues with the hybridapp insecure connection piece, which kind of worked but not for really new devices? That said, the Play Store will reject it so if you don't rely on that change this back to not set the target (which is what we had in the past), or set the target to the same value as the minSdkVersion?

I vaguely remember that we had similar issues with iOS at the beginning which we solved by become a required service, e.g. something that plays music or acts as a VoIP app, which could be declared in the manifest. https://developer.android.com/guide/components/services might have some ideas of adding a Foreground service? I can try to help but don't have an Android device available to me for testing, which makes this difficult.

Looks like having fixed the androidforegroundservice to work again has dealt with the issue. Getting the events again.

Are those commits included in #256 or is this a different piece you are developing?
