Difference between Activity and FragmentActivity
android, android-fragmentactivity, android-fragments, android-support-library
Solution
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.
Problem
I was working on fragments and came across two things `Activity` and `FragmentActivity` which are used several times. I want to know that is there any difference between these two, because when I changed `Activity` with `FragmentActivity`, it had no effect on the app.
