8. ARCHITECHTU
RE
The software stack is split into Four Layers:: •
• The application layer
• The application framework
• The libraries and runtime
• The kernel
9.
10. Linux kernel
The architecture is based on the Linux2.6 kernel.
This layer is core of android architecture. It provides
service like power management, memory
management, security etc.
It helps in software or hardware binding for better
communication.
11. NATIVE
LIBRARIES
Android has its own libraries, which is written in C/C+ +.
These libraries cannot be accessed directly.
With the help of application framework, we can access
these libraries.
There are many libraries like web libraries to access web
browsers, libraries for android and video formats etc.
12. Android Run
Time
The Android Runtime was designed specifically for Android to
meet the needs of running in an embedded environment
where you have limited battery, limited memory, limited CPU.
Dalvik is the process virtual machine in Google's android
operating system.
It is the software that runs the apps on android devices.
Programs are commonly written in java and compiled to byte
code
13. Countid.
it's written in the Java programming language.
•The core library contains all of the collection
classes, utilities, IO, all the utilities and tools
that you’ve come to expected to use.
14. Application Framework
This is all written in a Java programming language and
the application framework is the toolkit that all
applications use.
•These applications include the ones that come with a
phone like the home applications, or the phone
application.
all apps use the same framework and the same APIs.
15. APPLICATION LAYER
the final layer on top is Applications.
It includes the home application the contacts
application , the browser, and apps.
It is the most upper layer in android architecture.
All the applications like camera, Google maps,
browser,sms,calendars,contacts are native
applications. These applications works with end user
with the help of application framework to operate.
