The way this works will never be a fully working solution, because uris are
*not supposed* to be resolved to a filesystem path. So while this may work
right now, it will most probably fail in the future, with other content providers.
See e.g. https://github.com/iPaulPro/aFileChooser/issues where this code originally came from
(via Stackoverflow).
We won't crash anymore, but we won't support certain content providers. In the long run, we
should search for the proper solution.
Closes#982
So we do need to set the language both on change and onCreate()
For some reason, the title bar of the SettingsActivity is not updated on recreate().
Closes#787
- cleaned up the DeviceService.connect() variants
- discovery: pass the device candidate around instead of the mac address
Attempts to fix#512, #514, #518
- pass service uuids to GBDeviceCandaidate so that DeviceCoordinators
can detect devices by their services.
Note: they should not rely on service uuids being available
