2. ◇ App Inventor for Android is an open-
source web application originally provided
by Google, and now maintained by the
Massachusetts Institute of Technology (MIT).
◇ App Inventor lets you develop applications
for Android phones using a web browser and
either a connected phone or emulator.
◇ The App Inventor servers store your work
and help you keep track of your projects.

4. ◇ It allows newcomers to computer
programming to create software
applications for the Android OS.
◇ It uses a graphical interface, which allows
users to drag-and-drop visual objects to create
an application that can run on Android
devices.

6. We build apps by working with:
 The App Inventor Designer, where we select
the components for your app.
 The App Inventor Blocks Editor, where we
assemble program blocks that specify how the
components should behave.
 You assemble programs visually, fitting pieces
together like pieces of a puzzle.

7.  Our app appears on the phone step-by-step as
you add pieces to it, so you can test your work
as you build. When you're done, you can
package your app and produce a stand-alone
application to install.
 We can build your apps using the Android
emulator, software that runs on your
computer and behaves just like the phone.
