  12. Architecture • Linux Kernel • Libraries & Android Runtime • Application Framework • Applications

  13. Linux Kernel • Android Architecture is based on Linux 2.6 kernel. • It helps to manage security, memory management, process management, network stack and other important issues. • User should bring Linux in his mobile device as the main operating system.

  14. Android Runtime • It was designed specifically for Android running in limited environment. • Which converts generated byte code from .jar to .dex file. • Conversion From .jar to .dex

  15. Libraries • Set of native libraries written in C/C++. • They are responsible for stable performance of various components. • Surface Manager is responsible for composing different drawing surfaces on the mobile screen.

  16. Application Framework • Application Framework is written in Java language. • It is a toolkit that all applications use. • It has several components. • The Activity Manager manages the life circle of the applications and provides a common navigation back stack for applications • The Package Manager keeps track of the applications, which are installed in the device.

  17. Development Tools • Java • Android SDK:- • Class Library • Developer Tools • Emulator and System Images • Documentation and Sample Code • Eclipse IDE + ADT (Android Development Tool) • Reduces Development and Testing Time • Makes User Interface-Creation easier • Makes Application Description Easier

  18. Advantages • Open • All applications are equal. • Breaking down boundaries. • Fast and easy development

  19. Disadvantages • Security • Open Source • Login • Incompetence
