Navigation issue (?)

[nicolgit]

I'm new to Android programming so I'm not sure if this is correct but I'd like to implement this sequence:

(1) start a fragment (home page) (2) go to an activity (I need to show a full screen page) (3) show another fragment activity

In the attached sample I have added a button on MessageActivity that jumps to ExampleRecyclerViewModel.

this is the sequence: (1) start application (2) open compose message activity (from menu) (3) tap on "click me" button (" ShowViewModel ();") (4) Instead to show ExampleRecyclerViewModel an exception is raised

"ava.Lang.NullPointerException: Attempt to invoke virtual method 'java.lang.Object java.util.ArrayList.set(int, java.lang.Object)' on a null object reference"

Is this my misunderstanding or a bug? How can obtain this behavior?

thank you!
