 This project is an Android app, that works as a client for a [Syncthing][1] share (accessing 
-Syncthing devices in the same way a client-server file sharing app accesses its proprietary server). 
+Syncthing devices in the same way a client-server file sharing app access its proprietary server). 
 
 This is a client-oriented implementation, designed to work online by downloading and 
 uploading files from an active device on the network (instead of synchronizing a local copy of 
-the entire repository).
-Due to that, you will see a sync progress of 0% at other devices (and this is expected).
-This is quite different from the way the [syncthing-android][2] works, 
-and it's useful for those devices that cannot or do not wish to download the entire repository (for

-Due to the behaviour of this App and the [behaviour of the Syncthing Server](https://github.com/syncthing/syncthing/issues/5224),
-you can't reconnect for some minutes if the App was killed (due to removing from the recent App list) or the connection was interrupted.
-This does not apply to local discovery connections.

-install [Android Studio][3] and import the project.

+the local maven repository. To do this, clone the repo and run `gradle install` in the
+syncthing-java project folder.

-- do tests
-- update translations using ``tx pull -a -af`` (as extra merge request or branch for the case it does not build correctly)
-- update the version name and version code of the app
-- update the changelog at [app/src/main/play/en-GB/whatsnew](https://github.com/syncthing/syncthing-lite/blob/master/app/src/main/play/en-GB/whatsnew)
-- create a tag/ release in GitHub with an changelog; The tag name should be the version number
-- F-Droid picks up the release by the tag; additonally, the tag triggers a CI build which uploads the generated APK to Google Play

-/**
- * This class manages the access to an LibraryInstance
- *
- * Users can get an instance with startLibraryUsage()
- * If they are done with it, the should call stopLibraryUsage()
- * After this, it's NOT safe to continue using the received LibraryInstance
- *
- * Every call to startLibraryUsage should be followed by an call to stopLibraryUsage,
- * even if the callback was not called yet. It can still be called, so users should watch out.
- *
- * All listeners are executed at the UI Thread (except the synchronousInstanceCreator)
- *
- * The userCounterListener is always called before the isRunningListener
- *
- * The listeners are called for all changes, nothing is skipped or batched

-This project is an Android app, that works as a client for a Syncthing share (accessing Syncthing devices in the same way a client-server file sharing app access its proprietary server).
-
-This is a client-oriented implementation, designed to work online by downloading and uploading files from an active device on the network (instead of synchronizing a local copy of the entire repository). This is quite different from the way the syncthing-android works, and its useful from those devices that cannot or wish not to download the entire repository (for example, mobile devices with limited storage available, wishing to access a syncthing share).
