[v2.0.2] Network Drops / Lost connection to Server

[ghost]

I noticed during use that when you change the network (from mobile to WLAN or 4G to Edge) there is often a break in the connection to the server.
The problem here, the reconnect to the server is not always happening, so the app is often not connected to the server.

With the version running without GApps, this means that you have to go into the setting of Android, kills the app and must restart to re-establish a connection.
Here a kill switch would be good, which determines that no connection was established and after a certain time pattern it tries again:

5 min
10 min
15 minutes
30 min
45 min

And then a notification to the user that the app must be stopped. So he tries it a few times and then the app simply remains unconnected.
Also good, then would be a notification if you open the app that there is no connection to the server if you should restart the app. If you click yes, the app will restart. So you do not have to go into the settings to kill the app.
