Computing.

10. ANDROID SDK
 Android software development is the process by
which new applications are created for
the Android operating system.
 Applications are usually developed in
the Java programming language using the
Android Software Development Kit.

11. DESIGN
• Android is based on the Linux kernel,
with middleware, libraries and APIs written
in C and application software running on
an application framework which includes Java-
compatible libraries based on Apache Harmony.

12. FEATURES OF ANDROID

13. SOFTWARE FEATURES
• Integrated browser based on the open source
Web Kit engine
• SQLite for relational data storage
• Media support for common audio, video, and still
image formats
• Dalvik Virtual Machine optimized for mobile
devices

14. HARDWARE FEAUTURES
• Cellular networking : GSM, EDGE, 3G
• LAN : Bluetooth, and Wi-Fi
• Graphics Hardware Acceleration
• Camera, GPS and Compass

sensing

15. SECURITY
• Android applications run in a sandbox, an
isolated area of the operating system that does
not have access to the rest of the system's
resources, unless access permissions are granted
by the user when the application is installed.

16. WHAT MAKES AN ANDROID SPECIAL
• Open source – Free development platform
• Built in components can be improved
