Please note that all apps uploaded to the Play Store need to have a target API level >= 26 (Oreo). This means (among other things) that notifications need to have a channel (see https://developer.android.com/training/notify-user/channels). The current code will fail as soon as the app developer has a target API >= 26 specified. See https://developer.android.com/training/notify-user/channels for details. I would know how to do the required Java changes (I have done it for KDE Connect D9514 <https://phabricator.kde.org/D9514>) but I'm not sure if/how it's possible to do it without the support library/androidx and adding it to the build seems above my knowledge.
