how to know when device connect to internet (Wi-fi/Mobile data) in Android

i want to communicate to the server as soon as device connects to the wi-fi or mobile data. Currently i am using broadcast receiver to notify when devices connects to wifi code is below:

<receiver android:name="com.example.rup35h.WifiReceiver" >
        <intent-filter android:priority="100" >
            <action android:name="android.net.wifi.STATE_CHANGE" />
        </intent-filter>
    </receiver>

My concern is will it work when device will connect to mobile data. will this also get called when user will turn on the mobile data/3G network.

Please let me know if any one will have something related to this. Thanks in advance.

No, it won't execute so to make it work when you are using mobile data/3G network, you have to add this also

<action android:name="android.net.conn.CONNECTIVITY_CHANGE" />

To check whether you are connected with WiFi

ConnectivityManager cm = (ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
boolean isWiFi = activeNetwork.getType() == ConnectivityManager.TYPE_WIFI;

Ah, I see in your comment

i just need to check whether device is connected or not thats all.

It is very simple which you can do like below

/**
 * This method check mobile is connected to network.
 * @param context
 * @return true if connected otherwise false.
 */
public static boolean isNetworkAvailable(Context context) {
    ConnectivityManager conMan = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
    if(conMan.getActiveNetworkInfo() != null && conMan.getActiveNetworkInfo().isConnected())
        return true;
    else
        return false;
}
