permanent login screen if data connection available but no server connection

[endym]

ownNotes is not usable in following situation:
If there is a network available (e.g. mobile data connection) but no connection to the owncloud server, then ownNotes shows the login screen (pre-filled with server credentials). Of course the login will fail and the login screen appears again. There is no way to see the offline saved notes.

environment:

• owncloud 8.1.1
• ownnote (server app) 1.05
• ownNotes 1.0
• Android 4.4.2 (Samsung S5 mini)
