Android popBackStack setTransition

Question

I am trying to figure out what is the proper way to play transition animation when popBacksStack is called.

Right now I am setting the transition from ListFragment to SettingsFragment like this

getSupportFragmentManager()
    .beginTransaction()
    .addToBackStack(null)
    .setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN)
    .replace(R.id.fragment_holder, settingsFragment)
    .commit();

But how should I play the transition when popping backstack (Moving back so that ListFragment becomes visible again)?

As I noticed, popping backstack is not a fragmentManager transaction like replacing a fragment so I cannot call the setTransition before making the pop.

I would like to keep the code as simple as possible. No custom animations etc.

Solution: I ques I have got too used to Android Studio being smarted than me. Android studio didn't recognize android.R as resource so I thought there is not such thing, but when I started to type in the full path 'android.R.anim.slide_in_left' Android studio picked it up. So my solution looks like this now:

getSupportFragmentManager()
                    .beginTransaction()
                    .addToBackStack(null)
                    .setCustomAnimations(android.R.anim.slide_in_left, android.R.anim.slide_out_right, android.R.anim.slide_in_left, android.R.anim.slide_out_right)
                    .replace(R.id.fragment_holder, settingsFragment)
                    .commit();

getSupportFragmentManager()
.beginTransaction()
.addToBackStack(null)
.setCustomAnimations(R.anim.enter, R.anim.exit, R.anim.popEnter, R.anim.popExit )
.replace(R.id.fragment_holder, settingsFragment)
.commit();

That looks like a simple and nice solution, but I don't have any animation content under R.anim... Doesn't android provide any default animations? Can I download some default animations using Android SDK Manager or from somewhere else? Normally I would just make some XML animations or copypaste from stackoverflow but I want to know what is the smart way. – Nabuska Feb 17 '16 at 14:14
