AppCompatDialog vs DialogFragment

Question

With the latest AppCompat

compile "com.android.support:appcompat-v7:22.2.1"

There is both available AppCompatDialog and DialogFragment which one should I prefer are there any differences or problems that can I avoid?

Edit:

I tried to use either the AppCompatDialog or DialogFragment by converting an existing Dialog that I had, but in none the getDialog().setTitle("Title") seem to work.

The [DialogFragment][1] and the [AppCompatDialog][2] are completely different.[1]: developer.android.com/reference/android/support/v4/app/… [2]: developer.android.com/reference/android/support/v7/app/… – Pelagianism

Update 17 May 2021:

Quoting from Android Documentation:

A dialog is a small window that prompts the user to make a decision or enter additional information. A dialog does not fill the screen and is normally used for modal events that require users to take an action before they can proceed.

You should use a DialogFragment as a container for your dialog. The DialogFragment class provides all the controls you need to create your dialog and manage its appearance, instead of calling methods on the Dialog object.

Using DialogFragment to manage the dialog ensures that it correctly handles lifecycle events such as when the user presses the Back button or rotates the screen. The DialogFragment class also allows you to reuse the dialog's UI as an embeddable component in a larger UI, just like a traditional Fragment (such as when you want the dialog UI to appear differently on large and small screens).

Note: AppCompatDialog is a Dialog extension.
