"Kill" fragment after replace it

I have a MainActivity with two tabs (using viewPager). In the second tab I have a mapFragment - Google Maps API. After clicking in a button it would open another fragment. However, the mapFragment is under the fragment (in log I see that the map is re-drawn).
Any suggestion how to solve it?
If you are using add() to go to the new fragment, replace it with replace().
See this example:
final FragmentTransaction ft = getFragmentManager().beginTransaction();
ft.replace(R.id.container, new NewFragment(), "NewFragment");
ft.commit();

How to reload fragment in ViewPager each time the page is selected?

I am using mViewPager.setOnPageChangeListener to detect when a user navigated to a specific page. Each time he navigates to this specific page, I have to reload the Fragment or return it to its original state.
I tried using replace but the app breaks on the first parameter which is the ViewPager itself.
android.support.v4.app.FragmentManager fragmentManager = getSupportFragmentManager();
android.support.v4.app.FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
MyFragment fragment = new MyFragment();
fragmentTransaction.replace(R.id.viewPager, fragment);
fragmentTransaction.commit();
I tried to use the adapter itself, but I was brought to a dead end.
Where am I making a mistake? How can I reload the fragment each time a user navigate to a specific page?

Delay with Android NavigationDrawer

I've followed Google's recommended implementation of the Navigation Drawer and now have an introductory Fragment and Map fragment that I transition between. The drawer worked smoothly until I added ActionBarSherlock to my project. Now, when the home (original fragment) is selected the menu is delayed closing and I get an annoying flash before the home fragment appears.
The fragment transaction is handled by:
FragmentTransaction transaction = fragmentManager.beginTransaction();
transaction
.setCustomAnimations(android.R.anim.fade_in, android.R.anim.fade_out)
.replace(R.id.content_frame, fragment, null)
.commit();
Any suggestions are welcome.

When needed, create a new FragmentTransaction, call replace() on it to indicate what is to be replaced, then commit() the transaction
