AnimationDrawable

AnimationDrawable is a class in the Android framework that allows developers to create simple frame-by-frame animations. It is a subclass of Drawable and is used to display a sequence of images in a loop, creating the illusion of motion. This class is particularly useful for creating animations that do not require complex interactivity or user input.

To use AnimationDrawable, developers first need to define the animation in an XML file. This file specifies the sequence of images to be displayed, along with the duration for which each image should be shown. The XML file is then referenced in the application's layout or code to create an instance of AnimationDrawable.

Once created, the AnimationDrawable can be started and stopped programmatically using methods such as start() and stop(). Developers can also control the animation's behavior, such as whether it should loop indefinitely or run only once.

AnimationDrawable is a lightweight and efficient way to create simple animations in Android applications. However, for more complex animations that require interactivity or user input, developers may need to use other animation techniques, such as Property Animations or View Animations.
