I have DialogFragment and a Loader.

Dialog prompts user to logout from Application.

When user chooses to logout I fire Loader which clears the preferences and database and then I finish current Activity.

After Loader is finished I would like to start a new Activity with login screen, but I encounter two problems:

  1. getActivity() method returns null
  2. I’m not able to run new Activity because I’m out of Activity context

Do You have any solutions for this?

    It doesn’t sound like your situation warrants the use of a Loader or the LoaderManager at all.

    1. Use an AsyncTask to clear the preferences and database (perhaps showing a ProgressDialog of some sorts if this operation is time-consuming).

    2. When the task is complete, onPostExecute is called. Write a callback method from the fragment to the activity which will first call startActivity(...) and then call finish().
