Android: Reduce time to open settings widget

Two major areas of improvement:
- Make connections last, so that the initial setup does not trigger any
  unnecessary checks.
- Make fetching the list of android virtual devices a background
  operation.

Together they reduce the time needed to open the settings for me by
roughly 10 times.
