Is there any way replace a fragment with FragmentTransaction's replace, and NOT add it to history stack?
I just want my app to dont remember it, when i push back button.

Android app must have an Activity or FragmentActivity that handles the fragment. Fragment can't be initiated without Activity or FragmentActivity.
Solution: Save required information as an instance variable in calling activity. Then pass that instance variable into your fragment. So following on with my example: before I display F2 I save user data in the instance variable using a callback. Then I start F2, user fills in phone number and presses save.
Add a fragment to an activity You can add your fragment to the activity's view hierarchy either by defining the fragment in your activity's layout file or by defining a fragment container in your activity's layout file and then programmatically adding the fragment from within your activity.
A fragment is a reusable class implementing a portion of an activity. A Fragment typically defines a part of a user interface. Fragments must be embedded in activities; they cannot run independently of activities.
When you use FragmentTransaction to add fragment there is addToBackStack() method, if you don't use it, it won't be in the stack.
// it won't add to stack
getSupportFragmentManager().beginTransaction()
.add(R.id.container, new PlaceholderFragment())
.commit();
// fragment will be added to stack
getSupportFragmentManager().beginTransaction()
.add(R.id.container, new PlaceholderFragment())
.addToBackStack("placeholder")
commit();
By default fragments are not added to backstack. You need to remove call to addToStack() from your code.
