Phonegap not works Connection object

I am using cordova and android platform.

var CORDOVA_JS_BUILD_LABEL = '3.0.0-0-ge670de9';
AVD platform 4.2.2 API level 17

I am trying to use Connection object I added next string into app/res/xml/config.xml

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

and next string into app/AndroidManifest.xml

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> 
<uses-permission android:name="android.permission.READ_PHONE_STATE" />

my code 

    onDeviceReady: function() {
    var networkState = navigator.connection.type;

    alert('networkState = '+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.CELL]     = 'Cell generic connection';
    states[Connection.NONE]     = 'No network connection';

    alert('Connection type: ' + states[networkState]);

    app.receivedEvent('deviceready');
},

result of first alert: networkState = 0

the remaining part of code not works, it seems like object Connection not exists.

I have no idea what is wrong, can anybody to help me?

Thanks.

PS. I had used this example http://docs.phonegap.com/en/3.0.0/cordova_connection_connection.md.html#Connection

All the answers above are kind of right but not complete.

If you are still not able to get the Connection and if your "online" and "offline" event are not working, it means that the plugin is not working properly.

Here are the steps I did to make it work:

1/ in your index.html instead of loading phonegap.js (and forget about using the phonegap cmd but use cordova instead)

<script type="text/javascript" src="cordova.js"></script>

2/ add the plugin if you didn't yet

cordova plugin add org.apache.cordova.network-information

3/ build your app (will erase your platforms/yourplatform/www/ directory by the /www one)

cordova build

The latest is what made the difference for me ! 2/ was adding the files to my project and editing my config.xml and androidmanifest.xml the right way, but was not adding the source files. Doing 3/ made everything work properly

Right, I got the same issue with Phonegap 3.0 on Android 4.2.2 Api 17.

What I have noticed in the logs is the following line right after the ERROR message:

10-11 14:31:40.360: E/Web Console(): Uncaught ReferenceError: Connection is not defined
10-11 14:31:40.380: D/CordovaNetworkManager(): Connection Type: wifi

So I was thinking that it actually looks like it was an async callback after successfully initializing Connection.type from CordovaNetworkManager() however it shouldn't be.

So I tried the following:

var networkState = navigator.connection.type;

setTimeout(function(){
    networkState = navigator.connection.type;
    alert('networkState = '+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.CELL]     = 'Cell generic connection';
    states[Connection.NONE]     = 'No network connection';

    alert('Connection type: ' + states[networkState]);
 }, 500);

I know it looks a bit stupid but works every time. What it does is first calls navigator.connection.type and then runs the whole function 500ms later giving time to CordovaNetworkManager to initialize the connection.type.

I've noticed that your console log reports

Could not find cordova.js script tag. Plugin loading may fail. at file:///android_asset/www/phonegap.js:1836

This is a long thread about this error: https://github.com/phonegap/phonegap-cli/issues/134

As a temporary solution they suggest to change this line

<script type="text/javascript" src="phonegap.js"></script>

with

<script type="text/javascript" src="cordova.js"></script>

in index.html
