Well this is just ridiculous. I have a login screen and when the user presses "Log in" I want to display a ProgressDialogFragment saying "Logging in. Please wait...". I have a AsyncTaskLoader that does the authentication against a Web Service and returns the result. Once I have the result I want to remove the ProgressDialogFragment... but according to you that's impossible because I am not allowed to talk to fragments in the onLoadFinished callback?
My previous solution was using the AsyncTask<T> and ProgressDialog class but they are "deprecated" and I was told to use Fragments and Loaders instead since they have been backported. I would really like to know what you consider to be "best-practice" when it comes to doing async work and notifying the user?
