This introductory module will guide you through building a “Magic 8-Ball” app with App Inventor. When activated, your 8-ball will deliver one of its classic predictions, such as “It is decidedly so” or “Reply hazy, try again.” At first you activate the 8-Ball by clicking a button. If you are using a device (rather than the emulator) you can add in an accelerometer component so that the 8-Ball makes a new prediction whenever the device is shaken. Note: This tutorial can be used in place of Hello Purr since it initially has the same functionality, and then goes on to the extend that functionality.
