Android : Android find fragment by id log.d output

So I have been playing around with fragments and I am a big fan of using Log.d to see the output of methods and such to better understand things.

I'm at the point where I'm using findFragmentById.

When I use these Log.d statements:

Log.d("APPTAG", "Fragment: "+ getSupportFragmentManager().findFragmentById(R.id.pager));
Log.d("APPTAG", "Fragment is visible : "+ getSupportFragmentManager().findFragmentById(R.id.pager).isVisible());

I get these results:

APPTAG﹕ Fragment: FragmentTwo{52742bec #1 id=0x7f070077 android:switcher:2131165303:1}
APPTAG﹕ Fragment is visible : true

So the way I understand this is that for a smooth user experience the current fragment as well as the previous and next fragments are created for a smooth transition between them.

I am using this tutorial for setting it all up. I have 3 fragments and only fragment one has a button that calls a method to use the log.d statements.

For those who don't want to look at the link. I'm using a ViewPager and FragmentPagerAdapter to create the fragments.

Question:

1. Can someone explain to me why am I not getting the values for fragment one?


2. If possible how can I get them?


3. Why when I am getting the values for fragment two does it say fragment two is visible when fragment one is currently in view/on screen?

Thanks
