What will be the context for CONNECTIVITY_SERVICE in Fragment?

Question

What will be the context for CONNECTIVITY_SERVICE in a Fragment? I have checked getActivity also but it is giving an error.

public boolean isOnline() {
    ConnectivityManager connectionManager = (ConnectivityManager) 
        getSystemService(Context.CONNECTIVITY_SERVICE);
    try {
        if (connectionManager.getActiveNetworkInfo().isConnected()) {
            Log.d("ConStatus", "Data Connection On");
            return true;
        } else {
            Log.d("ConStatus", "Data Connection off");
            return false;
        }
    } catch (NullPointerException e) {
        Log.i("ConStatus", "No Active Connection");
        return false;
    }
}

Could you provide the stacktrace, when you're using getActivity? — Darwind, Oct 25 '12 at 21:16

getSystemService() is a method on Context. A Fragment would call it using getActivity():

getActivity().getSystemService(Context.CONNECTIVITY_SERVICE);

I faced a similar problem when trying to implement a Google map offline tile provider within a fragment (based on 0ne_Up's answer here). I solved it by using the following:

private ConnectivityManager connectivityManager;
...
connectivityManager = (ConnectivityManager) getActivity().
    getSystemService( getActivity().CONNECTIVITY_SERVICE );
