Discriminate between one stock uniquely not working and network error in general

[jimdc]

If one stock has a problem but others are working, it should say error loading price. Should be notified to the user, already has a return value internally.

Email developer automatically if HTML is malformed or if network code gives a redirect (like for NASDAQ, if you use uppercase, because it desires lowercase ticker names).

Resume connection automatically once connection is found, after stopped for error #41

Looks like Android has a built-in feature to monitor connectivity status using broadcast receivers https://developer.android.com/training/monitoring-device-state/connectivity-monitoring.html

It also pays to be mindful of mobile data connection in addition to WiFi https://stackoverflow.com/a/9754897
