While passing Android DialogFragment arguments, onCreateDialog bundle agument is unexpectedly null

Question

I am trying to display a basic dialog in Android using a DialogFragment using an argument for the dialog message as described in StackOverflow thread and DialogFragment document

Answer 1

you have to use getArguments to retrieve the Bundle you set with setArguments

Instead of

if(savedInstanceState != null) {
     dialogMessage = savedInstanceState.getString(DIALOG_MESSAGE);
}

you should have something like:

Bundle bundle = getArguments();
if (bundle != null) {
    dialogMessage = bundle.getString(DIALOG_MESSAGE);
}

Answer 2

I had the same problem, you have to use getArguments, as Blackbelt said.

The savedInstanceState will be available when onSaveInstanceState (documentation) is called and some data is filled in outState, to be retrieved latter.
