App Inventor Beginner Tutorials - 41 Test it out A good habit while building apps is to test while you build.

If you don't have a phone or emulator connected, go to the connection instructions and then come back to this tutorial. Connection instructions are in Tutorial 1 or on the website under "Getting Started".

Why does the Ball get stuck on the side of the screen?!

After flinging your ball across the screen, you probably noticed that it got stuck on the side. This is because the ball's heading has not changed even though it hit the side of the canvas. To make the ball "bounce" of the edge of the screen, we can program in a new event handler called "When Edge Reached". EdgeReached do event. Bounce block. Add the edge value for the Ball. Bounce block The Ball. Bounce method needs an edge argument.

Or the tag could be a phone number and the value could be the name of the person who has that phone number. The program is operated by entering a tag and a value and then pressing the Store Value button.

The value entered is written to the FirebaseDB database in the cloud. After a value has been stored, you retrieve values by entering the original tag and pressing Retrieve Value. The data corresponding to the tag is retrieved from FirebaseDB and display in the Value field, on screen. If the app is run simultaneously on other devices, any data updates made on the other devices result in all devices receiving a data changed notification. When the data in the FirebaseDB is changed, the new data is displayed on all devices.

Designer View A combination of vertical and horizontal layouts is used to organize the positions of the controls see the Components list, below, or download the sample code.
