- 16. Why Android is growing? • Open Source Developers • Free SDK • Easy To Use APIs • Free OEMs • Open Standards (Design/Hardware) Service • Suits Business Model Providers • Huge Market Space
- 17. Introduction to Android Platform Android is an open software platform for mobile development.
- 19. 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.
- 20. 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.
- 21. Android Run Time
- 22. Android Run Time
- 28. 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.
- 29. 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 Intent Receiver changes. Can wake up your process. • Faceless task that runs in the Service background. Content Provider • Enable applications to share data
- 30. Application Building Blocks An activity is a single, focused thing that the user can do. Activity Lifecycle Actual Representation
- 32. Actual Representation Componen t Lifecycles
- 33. Application Building Blocks They are nothing Else but messages. We need to intent if we need to start any Activity , Service or Broadcast Messages.
- 34. An Activity Diagram Activity Intent Activity One Two
- 35. 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.
- 36. Component Services Notification Communication Service Pause/rewind Background running /stop/restart for playback Media Player Activity Binder
- 37. 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
