46.  Linux Kernel.
 HAL(Hardware Abstraction Layer).
 Libraries & Android Run Time.
 Android Application FrameWork.
 Android Applications.

47.  Linux Kernel not interact with user & Developer.
 Performs : Memory Management Programs,
Security Settings,Power Management Software,
Network Stack,Support for
SharedLibraries,Hardware Drivers.

48. •
Android 1.0 ----------- 2.6.25.
•
Android 1.5 ----------- 2.6.27.
•
Android 1.6 ----------- 2.6.29.
•
Android 2.0 ----------- 2.6.29.

49.  Android is open source, therefore any manufacturer
can access it, customize it and adapt it according to the
requirements of their own gadget.
 kernel is the first layer of software that interacts with
the device hardware.
 The kernel is responsible for providing basic
architectural model for process scheduling, resource
handling, memory management, networking and
isolation etc.
 Google maintaining own Linux kernel for since 2010.

50.  Portability :Supports Super Computers to small devices.
 Features :
Memory Management : Linux kernel manages memory by
allocating and de-allocating memory for the file system.
Process Management : Linux Kernel is responsible to start
stop and execute the program.
Linux is responsible to allocate resources to various
processes that need them.
Driver Model : All the device specific drivers run.
Application is able to run on Android.
 Manufacturers/ hardware vendors can develop their drivers
into Linux in a familiar environment.
 That is giving plenty room for hardware vendors to
optimizing OS. This is one major reason Linux kernel was
chosen for Android.

51. File System Management: Contols Data storage service for
Android device.
Network Stack : Linux Kernel is responsible to communicate
with the network. It also controls networking stack, drivers,
routing devices and network adapters.
 Security :
Linux kernel handles the security between application
and the system.
Linux kernel is also responsible for power
management.
Linux runs in scientific research labs, supercomputers
and systems for mission critical tasks. Android
completely relies on Linux for security.

52. •
Libraries developed with C,having
•
Surface Manager: composing windows on
•
the screen.
•
WebKit : Browser.
•
Sqlite : DataBase.
•
libc (System C libraries).

53.  Android Runs on
its Own Process.
 It is optimized for
low memory req.
 Allow Multiple
Instance,run at Once
 Thread Support.
 Operates On dex
files.

54.  Our applications directly interact with these blocks of the Android
architecture. These programs manage the basic functions of phone like resource
management, voice call management etc.
 Telephony Manager: Manages all voice calls. We use telephony
manager if we want to access voice calls in our application.
Resource Manager: Manage the various types of resources we use in
our Application
Location Manager: Location management, using GPS or cell tower.

55.  Top Layer o Android stack is Application Layer. User
Interacting with this layer only.
 Blue Color : Developed with JAVA.
 Green Color : Developed with C.
 To Interface C & JAVA,need to Use JNI.

56. • Activity.
• Intents.
• Views.
• Content Providers.
• Services.
• Notification.
• Manifest file.

57.  Intent is one of the android application
component.
 Two types of intents are there
 Implicit Intent.
 Explicit Intent.
 Implicit Intent : WebView.
 Explicit Intent : Changing one Screen to
Another Screen.

58.  It is a component,user can interact with User
interface .
 An Android application can have several
activities and it can be switched between them
during runtime of the application.
 An Activity contains Views & Layouts.
 Each Android Application Contains min one
Activity.
 If morethan one Activity in application,need to
Declare in manifest file.

59.  Services perform background tasks without
providing an UI.
 Each service class must have a
corresponding <service> declaration in its
package's AndroidManifest.xml.
 They can notify the user via the notification
Manager.
 broadcast receiver is a class which extends
BroadcastReceiver.
 Getting Alerts.like mail,msg,etc.

60.  Different Types of
Layouts,Textviews,
Buttons,etc.
 View can be seen in Two
Ways.
 Using Emulator.
 Graphical View.

61.  Content providers store and retrieve data .
 Share the data across Application.
 The only way to share data across applications.

63. HelloWorld Program

87.  LinearLayout.
 RelativeLayout.
 TableLayout.
 GridLayout.
 Aboslute Layout.
 FrameLayout.

88.  Firefox OS is a Linux-based open source
