FragmentActivity vs managing Fragment using FragmentTransaction?

Question

many tutorials on Fragment found on the web (like this one) use FragmentActivity. It seems to be the static way of using Fragment, as opposed to the dynamic way using FragmentTransaction to load Fragment s in a container in a normal Activity.

I'm using API 12 and FragmentActivity is not there (it's in android.support.v4.app).

So if I don't use the Android support package, I can only manage Fragment dynamically, right? Why has FragmentActivity disappeared?

Thanks

That is completely wrong.

FragmentActivity is for use with the Android Support package, if you wish to use fragments prior to API Level 11. Both static (<fragment> in a layout) and dynamic (FragmentTransaction) fragments are supported both by FragmentActivity and by Activity (the latter only on API Level 11 and higher).

I'm using API 12 and FragmentActivity is not there (it's in android.support.v4.app).

Add the Android Support package to your project. For example, from Eclipse, and right-click over the project, choose Android Tools > Add Support package from the context menu.

No, you can use static or dynamic fragments with Activity on API Level 11.

Why has FragmentActivity disappeared?

It has not disappeared. For ease of use, they integrated the Android Support package JavaDocs into the main JavaDocs. Whenever you see a class in an android.support package, you know that it is from the Android Support package.
