Drawables
Provides classes to manage a variety of visual elements that are intended for display only, such as bitmaps and gradients. These elements are often used by widgets as background images or simply as indicators (for example, a volume level indicator).

Primarily a drawable
A Drawable is a general abstraction for "something that can be drawn." Most often you will deal with Drawable as the type of resource retrieved for drawing things to the screen; the Drawable class provides a generic API for dealing with an underlying visual resource that may take a variety of forms. Unlike a View, a Drawable does not have any facility to receive events or otherwise interact with the user.

AnimationDrawable
An object used to define frame-by-frame animations that can be used as a View object's background. Each frame in a frame-by-frame animation is a drawable resource. The simplest way to create a frame-by-frame animation is to define the animation in an XML file in the drawable/ folder, set it as the background to a View object, then call AnimationDrawable.run() to start the animation, as shown here. More details about the format of the animation XML file are given in Frame by Frame Animation. spin_animation.xml file in res/drawable/ folder:

The name attribute of an activity points to a classname
<activity android:name=".HelloWorld"
android:label="@string/app_name">
If you notice there has to be a class called .HelloWorld in the current package root.

Explanation
A layout animation controller is used to animate a grid layout's children. While LayoutAnimationController relies only on the index of the child in the view group to compute the animation delay, this class uses both the X and Y coordinates of the child within a grid.
In addition, the animation direction can be controlled. The default direction is DIRECTION_LEFT_TO_RIGHT | DIRECTION_TOP_TO_BOTTOM. You can also set the animation priority to columns or rows.
The default priority is none. Information used to compute the animation delay of each child are stored in an instance of idLayoutAnimationController.AnimationParameters, itself stored in the ViewGroup.LayoutParams of the view.

LayoutAnimationController
A layout animation controller is used to animated a layout's, or a view group's, children. Each child uses the same animation but for every one of them, the animation starts at a different time. A layout animation controller is used by ViewGroup to compute the delay by which each child's animation start must be offset.
The delay is computed by using characteristics of each child, like its index in the view group. This standard implementation computes the delay by multiplying a fixed amount of miliseconds by the index of the child in its parent view group. Subclasses are supposed to override getDelayForView(android.view.View) to implement a different way of computing the delay.
For instance, a GridLayoutAnimationController will compute the delay based on the column and row indices of the child in its parent view group. Information used to compute the animation delay of each child are stored in an instance of LayoutAnimationController.AnimationParameters, itself stored in the ViewGroup.LayoutParams of the view.

You will use "setLayoutAnimation" on the viewgroup by passing in the layout controller
viewGroup.setLayoutAnimation(
new LayoutAnimationController(animation, delay));
