> Working on the App harness, I've found that the application will crash immediately if
there is no network available (No 3G, no Wi-Fi) at startup time.
> From the Android docs, {{NetworkManager.getActiveNetworkInfo}} "Returns
> a NetworkInfo object for the current default network or null if no network default network
is currently active"
> [http://developer.android.com/reference/android/net/ConnectivityManager.html#getActiveNetworkInfo()]
> This results in an NPE at NetworkManager.java:201.
> {code:title=Stack trace}
