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

adding

dialog.getWindow().setType(WindowManager.LayoutParams.TYPE_SYSTEM_ALERT);

and

"android.permission.SYSTEM_ALERT_WINDOW"/> in manifest

It works for me now. After even close and open the application, gave me the error at that time.
