Permanent notification as alternative to Googles push notifications
On Android phones/tablets without Google Mobile Services (LineageOS without OpenGAPPS, for example) it would be great to have an alternative to Googles push notifications. Because on modern android versions, an app service that is permanently running in background get killed by the power saving function, it would be necessary to have a permanent notification like riot.im or Deltachat has. On Android 8, it is possible to hide this notification and don't hide other notifications (for new messages and calls) if there are different notification channels for the app. The option to use a permanent notification could be deactivated by default and manually activated if requested by the user.
