Currently, once a NetworkAgent has decided to connect, there's no way to disconnect without first connecting and having ConnectivityService tear down the connection. This is suboptimal because it causes the transport to keep retrying even if it knows that it will not be able to connect. Instead, allow the transport to abort a connection request that's in progress, as long as the agent is not yet registered with ConnectivityService. Also add locking to evalScores. evalScores should already have been taking a lock, because it accesses member variables that are also accessed by the send*methods.
