13. Introduction to Android Platform
 Android is an open software platform for mobile
development.

14. Android Architecture

15. 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.

16. 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.

24. 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.

25. Application Building Blocks
 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
Activity one screen.
• Responds to notification or status changes.
Intent Receiver Can wake up your process.
Service • Faceless task that runs in the background.
Content Provider • Enable applications to share data

26. Application Building Blocks
 An activity is a single, focused thing that the user
can do.
 Activity Lifecycle
 Actual Representation

28. Actual Representation

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

30. An Activity Diagram
Activity One Intent Activity Two

31. Application Building Blocks
 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.

32. 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
