ANDROID ARCHITECTURE

The software stack is split into Four Layers:

• The application layer

• The application framework

• The libraries and runtime

• The kernel

LINUX KERNAL

•The architecture is based on the Linux2.6 kernel. Android use Linux kernel as its hardware abstraction layer between the hardware and rest of the software.

•It also provides memory management, process management, a security model, and networking, a lot of core operating system infrastructures that are robust and have been proven over time

NATIVE LIBRARIES

•The next level up is the native libraries. Everything that you see here in green is written in C and C++.

ANDROID RUNTIME

•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.

•The DVM runs something called dex files, D-E-X and these are byte codes that are the results of converting at build time. Class and JAR Files.

•This is in blue, meaning that 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.

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. •It includes applications written by Google, and it includes apps that will be written by you. •So, all apps use the same framework and the same APIs.

•And the final layer on top is Applications.

•This is where all the applications get written.

•It includes the home application, the contacts application, the browser, and your apps.

•And everything at this layer is, again, using the same app framework provided by the layers below.
