FragmentHelper | - Helper of Fragment

Couple of things:

• in the original code you're creating a Bundle containing a Bundle, and put that in the Intent. Thus you have one Bundle that's not really necessary. You can call putExtra directly on the Intent.

• Calling intent.extras, or intent.getExtras() creates a copy of the extras bundle. So this is expected that you get two different bundles.

• It is expected that when you debug, extras has empty mMap. Bundle has lazy semantics, and only the first call accessing the data will unparcel it, thus populating mMap.

I'd guess that initally you were creating an Intent containing a Bundle containing a Bundle, but when accessing you were trying to skip one step. I recommend deleting existing code and starting over:

• creating Intent and putting special data using intent.putExtra(EXTRA_SPECIAL, specialObject) method;

• and then retrieving special data by calling intent.getSerializableExtra(EXTRA_SPECIAL).

This is everything that's needed here.
