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
