See also: App Inventor Glossary Commands and Expressions When an event handler fires, it executes a sequence of commands in its body.
A command is a block that specifies an action to be performed on the phone (e.g., playing sounds). Most command blocks are purple in color. The Play block is an example of a command in HelloPurr: Some commands require one or more input values (also known as parameters or arguments) to completely specify their action. Commands are shaped so that they naturally compose vertically into a command stack, which is just one big command built out of smaller ones. When this stack of commands are placed in a body of an event handler (e.g., the when.Button1.Click event handler), the command will be executed from the top to the bottom. Back to Main AI2 Concepts Control Flow When an event handler fires, you can imagine that it creates a karaoke-like control dot that flows through the command stack in its body.

Installing the Windows software for App Inventor Setup has two parts: Installing the App Inventor Setup software package.
This step is the same for all Android devices, and the same for Windows XP, Vista, Windows 7, 8.1, and 10.If you choose to use the USB cable to connect to a device, then you'll need to install Windows drivers for your Android phone. NOTE: App Inventor 2 does not work with Internet Explorer. For Windows users, we recommend using either Chrome or Firefox as your browser for use with App Inventor. You must perform the installation from an account that has administrator privileges. If you have installed a previous version of the App Inventor 2 setup tools, you will need to uninstall them before installing the latest version. Download the installer.Locate the file MIT_Appinventor_Tools_2.3.0 (~80 MB) in your Downloads file or your Desktop.
In most cases, App Inventor should be able to locate the Setup software on its own. Something not working right? Connecting to a phone or tablet with a USB cable. When you use App Inventor with a phone or tablet, that device communicates with the App Inventor software running in your computer's browser window.
This communication is managed by the AI2 Companion App running on the device. The instructions below (step 2) explain how to install the companion. The Companion can communicate with your computer over a wireless connection. This is the method strongly recommended by the App Inventor team. It does not require any additional software to be installed on your computer. There are, however, some environments where wireless connections won't work. Setting up a USB connection can be awkward, especially on Windows machines, which need special driver software to connect to Android devices.
