Program The I Have A Dream App

1. Follow the instructions in the video lectures to create the I Have A Dream app. In addition to what the video instructs, add a label to the lower left of the interface that says "by XYZ" where XYZ are your three initials (middle name if you have one, otherwise use X as the middle initial).
2. There are 5 discretionaty points for ehancements you make to the this app beyond what is shown in the videos. Discretionary points are not extra credit, they are part of the points for the assignment. That is, to get full credit for the assignment, you must make enhancements beyond the PaintPot app described in the videos. Add a clear "I Have A Dream" section label to your lastname_appinventor1 document. Add to the document a description of the enhancements you made to this.
3. Export the Project as an a file called lastname_dream.aia. To do this, go to the Project menu and choose -> My Projects. On that page, put a check next to the project you want to export. Then go back to the Projects menu and the button for exporting the .aia should be active. Use it to export the .aia file to your computer.
4. From the Build menu download to your computer your app as a .apk file called Dream.apk.
5. Upload the Dream.apk file to your account on the Computer Science Department web server.
6. Add to your portolio web pages, on the My Apps page, an entry to download the App (the Dream.apk file), as in this example.
7. Answer in your lastname_appinventor1 file:
   • There are two views in AppInventor: Designer and Blocks. One is to build the user interface and one is to code. Which is which? In your lastname_appinventor1 document describe examples of these from your app.
   • What is an event handler? Describe an example from your app.
   • What is a conditional? Describe an example from your app.

Program The PaintPot App

1. Follow this instructions in the video lectures in the lessons to create the PaintPot app. In addition to what the video instructs, add a label to the lower left of the interface that says "by XYZ" where XYZ are your three initials (middle name if you have one, otherwise use X as the middle initial).
2. Use a picture of you as the default background picture instead of the cat.
3. The user interface in the PaintPot tutorial app does not display the current chosen color-- the user can only tell what color will be drawn by actually drawing. Add immediate feedback for the user so that when he clicks to change color, the UI changes to make it clear which color is chosen by doing this: when a color button is chosen, change the background color of the button to its color, and gray others.
4. Provide a way for the user to control the thickness of the lines that are drawn, similarly to how the dot size can be changed. Hint: Check out the properties of the Canvas component for one concerning line width.
