Dialog throwing "Unable to add window — token null is not for an application” with getApplication() as context

Question

My Activity is trying to create an AlertDialog which requires a Context as a parameter. This works as expected if I use:

AlertDialog.Builder builder = new Al         


        

Answer 1

If you are using a fragment and using AlertDialog/Toast message then use getActivity() in the context parameter.

like this

ProgressDialog pdialog;
pdialog = new ProgressDialog(getActivity());
pdialog.setCancelable(true);
pdialog.setMessage("Loading ....");
pdialog.show();
