Intent action for network events in android sdk

Here’s a working example:

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

<receiver android:name=".receiver.ConnectivityReceiver">
    <intent-filter>
        <action android:name="android.net.conn.CONNECTIVITY_CHANGE" />
    </intent-filter>
</receiver>

.

public class ConnectivityReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        Log.d(ConnectivityReceiver.class.getSimpleName(), "action: "
                + intent.getAction());
    }

}
