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

I had to send my context through a constructor on a custom adapter displayed in a fragment and had this issue with getApplicationContext(). I solved it with:

this.getActivity().getWindow().getContext() in the fragments' onCreate callback.
