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, 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++.
It's at this level where a lot of the core power of the Android platform comes from.

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 data

Application Building Blocks
Application Building Blocks
An activity is a single, focused thing that the user can do.

They are nothing Else but messages.
We need to intent if we need to start any Activity , Service or Broadcast Messages.

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.

Application Building Blocks
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
