Enhancement on Refresh button

[JuliaFreitagBGSt]

It is not recognizable whether the refresh button is working, because in any case no reaction is visible.

We need some kind of buffering symbol, success report or action, when the refresh button is used.

@leagerndt Could you come up with a conecpt or idea for this?

[Stift]

The button has currently no functionality, therefore no indication is implemented. With #260 it will be used to push cached POI-data to the server.

Question @Stift If the user is using the app offline while doing entries, then gets home and connect to the internet - does the upload to our servers work? Is it possible to use the app offline?

[Stift]

Currently the app only works online.
In the future with #260 edited data will be stored on the device until sync'd.

What we miss:

• downloading maps (if map data is already cached it might work already not tested)
• downloading existing poi-data for a specific region (incl. pictures?)
• geofencing the map to the downloaded area (avoids misunderstandings) (optional)

Before the user goes offline we need to define what does that exactly mean so that we can assess what is needed. We could also define that only new entries are possible for offline usage, which would make it a bit easier.

@nscharioth @Stift Let's discuss this on friday after the dev weekly, ok? @leagerndt and I need some conceptual clarity

Qs: What happens now, if a user is offline? What happens if the user goes online? What do we want to provide, if the user is offline?

[JuliaFreitagBGSt]

What happens now, if a user is offline? - app is currently not usable at all
What happens if the user goes online? - app can be used, offline-data are NOT uploaded
What do we want to provide, if the user is offline? - see #260 as well, not included: downloading map and POI
