Check If The User Is Connected To The Internet And If Not Prompt The User To Turn On Data Services Android

I am making a check if the user is connected to the internet. If the user is not connected then prompt the user to turn on data services. This is the code that I am using to prompt

Solution 1:

public boolean isNetworkAvailable() {
    ConnectivityManager connectivity = (ConnectivityManager) ctx
            .getSystemService(Context.CONNECTIVITY_SERVICE);
    if (connectivity == null) {
        return false;
    } else {
        NetworkInfo[] info = connectivity.getAllNetworkInfo();
        if (info != null) {
            for (int i = 0; i < info.length; i++) {
                if (info[i].getState() == NetworkInfo.State.CONNECTED) {
                    return true;
                }
            }
        }
    }
    return false;
}
