Introduction to App Inventor for Android

Introduction to App Inventor for Android Adding information to the previous post I have quoted below the basic orientation to App Jnventor. App Inventor for Android lets beginning programmers create mobile applications for Google Android. With App inventor, you create applications on your laptop, using a Web browser, and install them on the phone to run them. Applications made with App Inventor are run just like any other Android application. You build App Inventor projects by combining standard components. Components are program elements that let you access the basic capabilities of the Android platform. Some components are very simple, like a Label component that just shows text on the screen, or a Button component that you press to initiate an action. Other components are more elaborate: a drawing canvas that can hold still images or animations, an accelerometer sensor that can detect when the phone moves, a component that makes phone calls, components that play music and video, components that get information from Web sites, and so on. Creating applications involves selecting components and writing simple programs to make them interact. For instance, an application might have three components: a button, a label, and a music player; clicking the button changes the text on the label and starts the music. The program behind this would tell the button to watch for a click event, and when that happens tell music player to start playing and tell the label to change its text. In App Inventor, you create these programs are created using the visual CodeBlocks language, where you make programs by fitting together program element blocks on the screen. Once an application is created, you tell App Inventor to build the application. This produces a barcode that you can use to install the application on your phone over the air. If you don't have a phone to develop on, you can debug applications using the Android Debugging Bridge (adb) and the Android Emulator. These programs are distributed as part of the Android System Development Kit (SDK), which we'll describe at the end of this tutorial. For now, we'll assume that you have a phone. If you don't have phone read the section below on Using the SDK and then come back and try the rest of the tutorial.
