Implement Single-Sign-On

[schaarsc]

There is a new idea been developed at https://github.com/nextcloud/Android-SingleSignOn
Should Notes-App use this library and introduce a dependency to Files-App?

I like the idea of providing a library for this stuff very much! However, I don't like the dependency to the Nextcloud files app.

I'm not sure, if the advantages dominate. I tend to say yes.

And here is the decision made at the conference: Yes, we will use Single-Sign-On because the advantages are high enough :)

I talked to @David-Development and i am sure he will support us if we are experiencing any problems. I will post a more detailled plan how we might achive this goal as soon as i am at home.

we could take the opportunity to also think of some more refactoring ... since we will touch the code anyway something like https://developer.android.com/jetpack/docs/guide could also be considered.

Early birds attention please :)

@korelstar @dan0xii and me have started some work to implement SSO in notes.

This is a very early state which still has some problems left to be resolved. (Mainly regarding migration, widgets and most importantly: The sync always performs a full sync due to a issue in the SSO lib).

If you want, you are welcome to join the work, report bugs and test the branch. We are happy about every feedback. Please provide feedback directly as comment in the PR.

Released on F-Droid (will be there in a few days). Check it out, test it, report bugs!

Thank you for patience.

Play Store will take some more time and more eye for review :)

Quick question: The update is still not available on F-Droid. Do you know why? Or the fastest way to contact the people from F-Droid to take a look at it?

[stefan-niedermann]

Patience, F-Droid hasn't built it (or any other app since 15. Dec.) yet: https://f-droid.org/wiki/index.php?title=Special:RecentChanges&hidebots=0&days=30&limit=500
