The Android project features an all-inclusive software stack designed for mobile devices, consisting of an operating system, middleware, and fundamental applications.
If you are interested in learning how to develop applications for Android, this platform is the perfect place to start. The site offers an abundance of documentation to help you master Android and create innovative mobile applications utilizing the platform. You can also peruse an early version of the Android SDK, which features sample projects with source code, development tools, an emulator, and all the libraries required to construct an Android application.
Android's core libraries offer a broad range of functions comparable to those found within Java's core libraries. Every Android application executes in its standalone process, with its copy of the Dalvik virtual machine. The Dalvik VM has been designed to enable a device to operate multiple VMs simultaneously, hence optimizing memory efficiency. The VM operates files in the Dalvik Executable (.dex) format customized for minimal memory usage. This register-based VM runs classes that have been compiled by a Java language compiler and then transformed into the .dex format by the "dx" tool included with the package.
The Dalvik VM is reliant upon the Linux kernel to operate core functionalities such as threading and low-level memory management. Android has a set of C/C++ libraries utilized by various components of the Android system which can be accessed by developers through the Android application framework. It comprises standard features such as System C Library, media libraries, surface manager, libWebCore, SGL, 3D libraries, FreeType, and SQLite.
Android comes equipped with an array of core applications, including email clients, SMS programs, calendars, browsers, contacts, maps, and others, all written in Java programming language. Core system services, such as security, process management, memory management, driver model, and network stack, rely on Linux version 2.6. Additionally, the kernel serves as an abstraction layer separating the hardware from the software stack.
