Introduction to Android Platform

Android is an open software platform for mobile

development.

Android Architecture

Linux Kernel

The architecture is based on the Linux 2.6 kernel.

Android use Linux kernel as its hardware abstraction

layer.

It also provides memory management, processmanagement, a security model, andnetworking, 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++.

It's at this level where a lot of the core power

of the Android platform comes from.

Android Run Time

Application Framework

Applications

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.

Now, if you're going to write an app, the first step is to

decompose it into the components that are supported by

the Android platform.

• UI component typically corresponding to one screen.Activity

• Responds to notification or status changes. Can wake up your process.Intent Receiver

• Faceless task that runs in the background.Service

• Enable applications to share dataContent Provider

Application Building Blocks


An activity is a single, focused thing that the user

can do.

Activity Lifecycle

Actual Representation

Actual Representation


They are nothing Else but messages.

We need to intent if we need to start any

Activity , Service or Broadcast Messages.

An Activity Diagram

Activity One Activity TwoIntent


A service run in the background.

User for long running task.

A good example is a music player.

A Service is not a separate process and A

Service is not a thread.


Content providers store and retrieve data and

make it accessible to all applications.

This is only way to share data across applications.

Examples of Content Provider – Contacts, SMS,

Calendar, User Define etc.. And NOT email
