    15. 15. Introduction to AndroidPlatform  Android is an open software platform for mobile development.
    16. 16. Android Architecture
    17. 17. 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.
    18. 18. Native Libraries The next level up is the native libraries. Everything that you see here in green is written in C and C++. Its at this level where a lot of the core power of the Android platform comes from.
    19. 19. Android Run Time
    20. 20. Android Run Time
    21. 21. Application Framework
    22. 22. Application Framework
    23. 23. Application Framework
    24. 24. Application Framework
    25. 25. Application Framework
    26. 26. 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.
    27. 27. Application Building Blocks Now, if youre 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 Intent Receiver changes. Can wake up your process. • Faceless task that runs in the Service background. Content Provider • Enable applications to share data
    28. 28. Application Building Blocks An activity is a single, focused thing that the user can do. Activity Lifecycle Actual Representation
    29. 29. Actual Representation Componen t Lifecycles
    30. 30. Application Building Blocks They are nothing Else but messages. We need to intent if we need to start any Activity , Service or Broadcast Messages.
    31. 31. An Activity Diagram Activity Intent Activity One Two
    32. 32. 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.
    33. 33. Component Services Notification Communication Service Pause/rewind Background running /stop/restart for playbackMedia Player Activity Binder
    34. 34. 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
    35. 35. Components - ContentProviders Application Activity Activity Application Application Activity Content Resolver Service Content Resolver Content Provider Content Resolver Remote Data SQLite XML Store
