Android SDK is a software development kit that enables developers to create applications for the Android platform. The Android SDK includes sample projects with source code, development tools, an emulator, and required libraries to build Android applications and functions.
Applications are written using the Java programming language and run on Dalvik, a custom virtual machine designed for embedded use which runs on top of a Linux kernel.
Main Features of Android (Operating System)
- Application framework enabling reuse and replacement of components
- Dalvik virtual machine optimized for mobile devices.
- Integrated browser based on the open source WebKit engine.
- Optimized graphics powered by a custom 2D graphics library; 3D graphics based on the OpenGL ES 1.0 specification (hardware acceleration optional)
- SQLite for structured data storage.
- Media support for common audio, video, and still image formats (MPEG4, H.264, MP3, AAC, AMR, JPG, PNG, GIF).
- GSM Telephony (hardware dependent).
- Bluetooth, EDGE, 3G, and WiFi (hardware dependent).
- Camera, GPS, compass, and accelerometer (hardware dependent).
- Rich development environment including a device emulator, tools for debugging, memory and performance profiling, and a plugin for the Eclipse IDE.
Download the Android SDK
Welcome Developers! If you are new to the Android SDK, please read the steps below, for an overview of how to set up the SDK.
If you’re already using the Android SDK, you should update to the latest tools or platform using the Android SDK and AVD Manager, rather than downloading a new SDK starter package. See Adding SDK Components.

Here’s an overview of the steps you must follow to set up the Android SDK:
- Prepare your development computer and ensure it meets the system requirements.
- Install the SDK starter package from the table above. (If you’re on Windows, download the installer for help with the initial setup.)
- Install the ADT Plugin for Eclipse (if you’ll be developing in Eclipse).
- Plus or sum Android platforms and other components to your SDK.
- Explore the contents of the Android SDK (optional).
To get started, download the appropriate package from the table above, then read the guide to Installing the SDK.
