Android - Using Connectivity Manager in a Fragment

Question

Okay so i had the problem of network usage in UI Thread and now using AsyncTask. I am using Fragments and have a problem.

When putting this line:

    ConnectivityManager connMgr = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);

I have to add getActivity() because its in a fragmetn, then the error goes away but then i get an error on this line:

 new DownloadWebpageTask().execute(stringUrl);

The error is: "No enclosing instance of type MainActivity is accessible. Must qualify the allocation with an enclosing instance of type MainActivity (egxnew A() where x is an instance of MainActivity)."

Any ideas on how to fix this?

Answer 1

My guess is that your DownloadWebpageTask is a non-static nested class of MainActivity .

You can make it static by changing it like so:

public static class DownloadWebpageTask extends AsyncTask<..> {
...
}

Alternatively, you could create a new DownloadWebpageTask by using the instance of MainActivity , like so:

mainactInstance.new DownloadWebpageTask();
