Here is a method you can use to validate whether a data connection is available or not:

public static boolean isDataConnectionAvailable(Context context) {
        ConnectivityManager connectivityManager =
                (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
        NetworkInfo activeNetworkInfo = connectivityManager.getActiveNetworkInfo();
        return activeNetworkInfo != null && activeNetworkInfo.isConnectedOrConnecting();
}

If this returns true then there is a data connection available.

Also make sure you add this to your manifest:

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

public static NETWORK_AVAILABILITY_STATUS getAvailableNetworkType(Context context)
    {
        ConnectivityManager connectivityManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
        NetworkInfo activeNetworkInfo = connectivityManager.getActiveNetworkInfo();

        if (activeNetworkInfo != null && activeNetworkInfo.isConnectedOrConnecting())
        {
            int type = activeNetworkInfo.getType();
            if (type == ConnectivityManager.TYPE_MOBILE)
            {
                return NETWORK_AVAILABILITY_STATUS.DATA_PLAN;
            }
            else if (type == ConnectivityManager.TYPE_WIFI)
            {
                return NETWORK_AVAILABILITY_STATUS.WIFI;
            }
        }

        return NETWORK_AVAILABILITY_STATUS.NO_NETWORK;
    }

Note : You need to have internet permission i.e

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

Note :This method does NOT guarantee that network is reachable, the connection might still timeout or not respond at all.

I use this way in my app:

public static boolean isConnect(Activity activity) {
    boolean flag = false;

    ConnectivityManager cwjManager = (ConnectivityManager) activity.getSystemService(Context.CONNECTIVITY_SERVICE);
    if (cwjManager.getActiveNetworkInfo() != null)
        flag = cwjManager.getActiveNetworkInfo().isAvailable();

    return flag;
}

And of course, you also need android permission:

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