Question

For some reason the Phonegap connection API returns null

function checkConnection() {
    var networkState = navigator.network.connection.type;
    alert(networkState);
    var states = {};
    states[Connection.UNKNOWN]  = 'Unknown connection';
    states[Connection.ETHERNET] = 'Ethernet connection';
    states[Connection.WIFI]     = 'WiFi connection';
    states[Connection.CELL_2G]  = 'Cell 2G connection';
    states[Connection.CELL_3G]  = 'Cell 3G connection';
    states[Connection.CELL_4G]  = 'Cell 4G connection';
    states[Connection.NONE]     = 'No network connection';

    document.getElementById('connections').innerHTML = states[networkState];
}

I run this function from the onDeviceReady function which is called when the device is running.

When everything is turned off I get null. Shouldn’t I get the Connection.NONE back instead of a null? It’s really annoying since I can’t check whether the phone has connection or not. It works fine when Wifi is turned on though.

Have a look at the PhoneGap discussion group: https://groups.google.com/forum/?fromgroups#!searchin/phonegap/navigator.network.connection.type/phonegap/oAggxryQzrw/hE8uhwN3ONgJ

If you’re using 1.6.0, you need to update res/xml/plugins.xml from

<plugin name="Network Status" value="org.apache.cordova.NetworkManager"/>

to be:

<plugin name="NetworkStatus" value="org.apache.cordova.NetworkManager"/>

(You need to remove the space in “Network Status”)
