Current targetSdkVersion 21 doesn't met mandatory requirements

[audkar]

Since 2018 November it is required that all applications target at least Android SDK version 26. Docs

I have looked to source code very briefly and see some changes which will be required to increase version:

• [ ] Runtime permissions
  • Location
  • External storage
• [ ] Doze mode, foreground services. Probably clean solution would be to refactor Wake lock to foreground service

Do you know any additional features which app uses and needs to update while migrating to target version 26?

Are you willing to accept contributions (PRs) to solve this issue?
