FragmentActivity和Activity的区别及何时使用两者

区别：A FragmentActivity is a subclass of Activity that was built for the Android Support Package.

The FragmentActivity class adds a couple new methods to ensure compatibility with older versions of Android, but other than that, there really isn't much of a difference between the two. Just make sure you change all calls to getLoaderManager() and getFragmentManager() to getSupportLoaderManager() and getSupportFragmentManager() respectively.

使用：use `Activity` if you are using `android.app.Fragment`; use `FragmentActivity` if you are using `android.support.v4.app.Fragment`. Never attach a `android.support.v4.app.Fragment` to a `android.app.Activity`, as this will cause an exception to be thrown.
