+
+## Introduction
+
+> ***Note:*** _This can should done independently._
+
+In this lab, you will be building an animated wish list using your knowledge of view and layout animation. The app should have an edit text where a user
+can type in his/her wish. After clicking the button "add a wish", the wish should get animated and then be added to the wish list on top
+of other wishes. The app does not have to look the same, but it needs to have the same functionality.  
+
+**Hint**: when adding a new text view to the list make sure to specify the position 0.
+
+## Exercise
+
+#### Requirements
+
+- contain an edit text (to type in a wish), button (to add a wish), text view (the place where the wish will get animated) and a
+view group (wish list)
+- edit text should be no more than one line
+- text view should get animated (use *alpha* and *rotate* types of animation)
+- a new wish should be added to the top of the list
+- input field should get cleared after a wish is added to the list
+
+**Bonus:**
+- add functionality to remove a wish from the list
+
+#### Starter code
+
+Take a look at the [starter-code](starter-code). The only class to work with is **MainActivity**. Add the views and take care of an event listener on the button. In the project, you can find a folder `anim/` with one file **animation.xml** for you to take care of the animation set. In the file **activity_main.xml** add
+the views. Do not forget about a view group where you will store all the wishes.
+
+You have a choice of coding layout animation in the xml file or in java class.
+
+#### Deliverable
+
+Here is a gif that shows view and layout animation:
