Android provides a rich application framework that allows you to build innovative apps and games for mobile devices in a Java language environment.
The documents listed in the left navigation provide details about how to build apps using Android's various APIs.

The primary way to write applications for an Android-based phone is still Java. Google provides a Software Development Kit (SDK) with all the documentation, libraries and tools you need. There's even an add-on for the open-source Eclipse Integrated Development Environment (IDE) to help you along. figure 1 Google recently released a new and improved version of what was previously called the Android Scripting Edition (ASE) now renamed to Scripting Layer for Android (SL4A). The first thing you need to do is download the appropriate SDK for your phone. Figure 2 Touching the SLA4 icon launches the scripting host which initially has only the Shell interpreter installed.
