replace to new fragment with FragmentManager

Question

I have a instance of FragmentManager (variable frgManager), I replace to new fragment by:

 // Fragments all use the same container
 frgManager.beginTransaction().replace(containerId, nextFragment, MyTag).commit();

Let's say I have three fragments A, B, C,

the app show fragments in the sequence of A-->B-->C. Everytime show next fragment, I call the code above.

The problem is after C is shown, I close C, then B is shown in foreground, but the onResume() of A is also called. Why? How to avoid that because I expect only B's onResume() get called in this case.

frgManager.beginTransaction().replace(containerId, nextFragment, MyTag).addToBackStack().commit();

Use addToBackStack when creating all of your fragments. This way, only 1 can be active at once.
