Android, Where's My Car? for App Inventor 2

You parked somewhere near the stadium, but when the concert ends you don't have a clue where the car is. Fortunately you haven't lost your Android phone that never forgets anything, and you remember you have the hot new app, Android, Where's My Car?. With this app, you click a button when you park your car, and the Android uses its location sensor to record the car's GPS coordinates and address. Later, when you reopen the app, it shows you a map from where you are to the remembered location-- problem solved! With this tutorial you'll be able to download a created app and then study the annotated blocks below to better understand the app and App Inventor programming in general. This app covers: GPS, TinyDB, and using Activity Starter to open a map.

Beginner Tutorials: Short Videos to get started

With these beginner-friendly tutorials, you will learn the basics of programming apps for Android.

Follow these four short videos and you'll have three working apps to show for it! After building the starter apps, which will take around an hour, you can move on to extending them with more functionality, or you can start building apps of your own design. Get started now with Video 1 (5 minutes).

Colored Dots for App Inventor 2

Colored Dots is a simple painting program that uses a second screen to select the paint colors. This tutorial serves as an introduction to creating apps that have multiple screens. This tutorial is for App Inventor 2.

Exploring with Location Sensor in AI2

The location sensor object is used to communicate with the global positioning satellite receiver (GPS) in your phone/tablet. When the LocationSensor communicates with the built-in GPS receiver, the GPS can determine the location of your device.  The sensor can also work with network/wifi location services.  Finding a location using the network uses very different techniques to determine a location. Location means, the device's present latitude and longitude or it can mean your street address.

Get the Gold for App Inventor 2

By building the Get The Gold App you will get practice with setting visibility, using Clock components and Timers, and detecting collisions in App Inventor. You'll program an application that has a pirate ship whose goal is to collect all the gold on the screen.

Hello Purr for App Inventor 2

Hello Purr is the Hello World tutorial for App Inventor. This simple exercise takes you through the very basics of App Inventor. In a very short time you will create a button that has a picture of a cat on it, and then program the button so that when it is clicked a "meow" sound plays. This version of the tutorial is for use with App Inventor 2.

LEGO EV3 Color Search

This tutorial shows you how to build a mobile app that instructs an EV3 LEGO robot to search for a certain color on a white surface bordered by black. The user can pick one color out of red, green, blue, or yellow for the robot to search. The robot will search across the white surface and turn around if it gets to the black border. Here is a demonstration video.

Lego EV3 Pet Robot

This tutorial helps you to build an app that allows the user to instruct an EV3 LEGO robot to do certain maneuvers and actions through voice commands. The user can pick one of several commands: forward, backward (reverse), stop, forward slow, forward fast, disconnect, circles, right turn (turn right), left turn (turn left). The robot will follow the user’s voice commands and perform the action for half a second before prompting the user for another command. If the user provides no commands, the previous command will be executed until another command is registered.

LEGO ® EV3 Tilt-to-Drive Tutorial

This tutorial lets you make an app that drives around an EV3 LEGO robot by tilting a phone or tablet. Tilting forward makes the bot go forward, back --> back, right --> right, left -->left. A steeper pitch will make the robot drive faster… etc.

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.
