App behavior undefined when blockchain changes

[jonathanraes]

The app assumes the network parameters. What happens if these are no longer valid?

It crashes with:

15:48:35.164 [NioClientManager] INFO  org.bitcoinj.core.PeerGroup - [188.226.149.56]:6799: Peer died      (0 connected, 0 pending, 1 max)

And it just starts up without this peer.

Maybe add a notification if it cannot connect to any of the peers?
