Magic 8-ball for App Inventor 2

This introductory module will guide you through building a “Magic 8-Ball” app with App Inventor 2. 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. This version of the tutorial is for use with App Inventor 2.
