Libraries
Android includes a set of C/C++ libraries used by various components of the
Android system. These capabilities are exposed to developers through the
Android application framework. Some of the core libraries are listed below:
- System C library - a BSD-derived implementation of
the standard C system library (libc), tuned for embedded Linux-based
devices
- Media Libraries - based on PacketVideo's OpenCORE;
the libraries support playback and recording of many popular audio and video
formats, as well as 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 - a modern web browser engine which
powers both the Android browser and an embeddable web view
- SGL - the underlying 2D graphics
engine
- 3D libraries - an implementation based on
OpenGL ES 1.0 APIs; the libraries use either hardware 3D acceleration
(where available) or the included, highly optimized 3D software
rasterizer
- FreeType - bitmap and vector font rendering
- SQLite - a powerful and lightweight relational
database engine available to all applications
