Android is a software stack for mobile devices that includes an operating system, middleware and key applications. It allows developers to write managed code in Java for the Dalvik virtual machine. The Android SDK provides tools and APIs to develop applications that use features like its application framework, SQLite database, media support and hardware integration. Developers can create Android applications by defining activities, services and content providers and connecting them with intents in the AndroidManifest file.
