Crash when activity launched with startActivityForResult() without ARG_CLOSEABLE extra

[gbak]

Launching activity with the Intent/StartActivity will crash the app with a null pointer exception

02-08 15:45:36.311 27680 27680 E AndroidRuntime: java.lang.NullPointerException: Attempt to invoke virtual method 'boolean java.lang.Boolean.booleanValue()' on a null object reference
02-08 15:45:36.311 27680 27680 E AndroidRuntime: 	at com.nbsp.materialfilepicker.ui.FilePickerActivity.onCreateOptionsMenu(FilePickerActivity.java:187)
02-08 15:45:36.311 27680 27680 E AndroidRuntime: 	at android.app.Activity.onCreatePanelMenu(Activity.java:3396)
02-08 15:45:36.311 27680 27680 E AndroidRuntime: 	at android.support.v4.app.FragmentActivity.onCreatePanelMenu(FragmentActivity.java:321)

Launched with:

       val intent = Intent( activity, FilePickerActivity::class.java)
        intent.putExtra(FilePickerActivity.ARG_FILTER, Pattern.compile(".*\\.txt$"))
        startActivityForResult(intent, 1)

FilePickerActivity.java contains a Boolean which is never initialized if ARG_CLOSEABLE is never supplied as an Intent Extra.

Surely deserves mentioned in on the main page, also fell foul to colorAccent, and colorPrimary etc, needing to be present in main apps resources, took all afternoon.
