Accessing the Feature
As of version 3.0, Cordova implements device-level APIs as plugins.
Use the CLI's plugin command, described in The Command-line
Interface, to add or remove this feature for a project:
$ cordova plugin add https://git-wip-us.apache.org/repos/asf/cordova-plugin-network-information.git
$ cordova plugin rm org.apache.cordova.core.network-information
These commands apply to all targeted platforms, but modify the platform-specific configuration settings described below:
Android
(in app/res/xml/config.xml) <feature name="NetworkStatus"> <param name="android-package" value="org.apache.cordova.NetworkManager" /> </feature> (in app/AndroidManifest.xml) <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />BlackBerry WebWorks
(in www/plugins.xml) <feature name="Network Status"> <param name="blackberry-package" value="org.apache.cordova.network.Network" /> </feature>iOS (in
config.xml)<feature name="NetworkStatus"> <param name="ios-package" value="CDVConnection" /> </feature>Windows Phone (in
Properties/WPAppManifest.xml)<Capabilities> <Capability Name="ID_CAP_NETWORKING" /> </Capabilities>Reference: Application Manifest for Windows Phone
Tizen (in
config.xml)<feature name="http://tizen.org/api/systeminfo" required="true"/>
Some platforms may support this feature without requiring any special configuration. See Platform Support for an overview.
connection.type
Checks the currently active network connection.
Description
This property offers a fast way to determine the device's network connection state, and type of connection.
Supported Platforms
- iOS
- Android
- BlackBerry WebWorks (OS 5.0 and higher)
- Tizen
- Windows Phone 7 and 8
- Windows 8
Quick Example
function checkConnection() {
var networkState = navigator.connection.type;
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]);
}
checkConnection();

API Change
Until Cordova 2.3.0, the Connection object was accessed via
navigator.network.connection, after which it was changed to
navigator.connection to match the W3C specification. It's still
available at its original location, but is deprecated and will
eventually be removed.
iOS Quirks
- iOS cannot detect the type of cellular network connection.
navigator.connection.typeis set toConnection.CELLfor all cellular data.
Windows Phone Quirks
When running in the emulator, always detects
navigator.connection.typeasConnection.UNKNOWN.Windows Phone cannot detect the type of cellular network connection.
navigator.connection.typeis set toConnection.CELLfor all cellular data.
Tizen Quirks
- Tizen can only detect a WiFi or cellular connection.
navigator.connection.typeis set toConnection.CELL_2Gfor all cellular data.
