// There are two iterations of the navigator.connection interface:
|
||
|
|
|
||
|
|
// The first is present in Android 2.2+ and only in the Browser (not WebView)
|
||

// : docs.phonegap.com/en/1.2.0/phonegap_connection_connection.md.html#connection.type
|

|
|
// : davidbcalhoun.com/2010/using-navigator-connection-android
|
||
|
|
|
||
|
|
// The second is specced at dev.w3.org/2009/dap/netinfo/ and perhaps landing in WebKit
|

// for more rigorous network testing, consider boomerang.js: github.com/bluesmoon/boomerang/
