Android Architecture is a softwares stack of some components which needs to support our mobile devices for variuos apps. Android software stack contains compenents such as: a Linux Kernel, C and c++ Libraries these are unveiled using an Application Framework Service.

Linux Kernel:

The heart of Android Architecture is known as the Linux Kernel which as responsible for various access such as:

• Power Management
• Device Driver Manage

Android Runtime:

In Android Runtime, there are core libraries like DVM (Dalvik Virtual Machine) which helps to run Android Apps Smoothly. DVM Consume Less memory uses and provide faster access to applications.

Android Framework:

Applications:

Android Applications such as Camera, Calender, Gallery, Browser, Games etc uses all the above libraries and linux kernel for effective ruuning in our Android Devices.
