If you are looking for a way to develop applications for Android, you are in the right place. This website offers a variety of documentation to help you understand and develop Android mobile applications. An early preview of the Android SDK is also available, which includes sample projects, development tools, an emulator, and all of the libraries required to build Android applications.
Android includes core libraries that provide most of the functionality available in the Java programming language's core libraries. Every Android application operates in its process, with its instance of the Dalvik virtual machine. Dalvik is designed such that a device can efficiently operate multiple VMs. The Dalvik VM operates on files in the Dalvik Executable (.dex) format, which is optimized for minimal memory footprint.
The Dalvik VM is register-based and operates on classes compiled by a Java language compiler that has been transformed into the.dex format by the included "dx" tool. The Dalvik VM relies on the Linux kernel for underlying functionality, such as threading and low-level memory management. Android includes a set of C/C++ libraries used by various components of the Android system, and these capabilities are exposed to developers through the Android application framework.
Android ships with a set of core applications such as an email client, SMS program, calendar, maps, browser, contacts, and others. All applications are developed using the Java programming language. Android depends on Linux version 2.6 for essential system services such as memory management, security, process management, network stack, and driver models. The kernel serves as an abstraction layer between the hardware and the rest of the software stack.
Some of the core libraries included in Android are the System C library, Media Libraries, Surface Manager, LibWebCore, SGL, 3D libraries, FreeType, and SQLite. The System C library is an embedded Linux-based BSD-derived implementation of the standard C system library (libc). The Media Libraries support playback and recording of popular audio and video formats, static image files, including MPEG4, H.264, MP3, AAC, AMR, JPG, and PNG. Surface Manager manages access to the display subsystem and seamlessly composites 2D and 3D graphic layers from multiple applications. LibWebCore is a modern web browser engine that powers the Android browser and an embeddable web view. SGL is the underlying 2D graphics engine. FreeType is bitmap and vector font rendering. SQLite is a lightweight and powerful relational database engine that is available to all applications.
