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

Just use following:

FOR JAVA USERS

In case you are using activity --> AlertDialog.Builder builder = new AlertDialog.Builder(this);

OR

AlertDialog.Builder builder = new AlertDialog.Builder(your_activity.this);

In case you are using fragment --> AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());

FOR KOTLIN USERS

In case you are using activity --> val builder = AlertDialog.Builder(this)

OR

val builder = AlertDialog.Builder(this@your_activity.this)

In case you are using fragment --> val builder = AlertDialog.Builder(activity!!)
