CB-6907: android: Don't crash on startup if no networks available
> Application crashes immediately on startup if no network is available
> ---------------------------------------------------------------------
>
> Key: CB-6907
> URL: https://issues.apache.org/jira/browse/CB-6907
> Project: Apache Cordova
> Issue Type: Bug
> Components: Android, Plugin Network Information
> Reporter: Ian Clelland
> Priority: Critical
>
> 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}
