    • HISTORY  2005 -Google acquired android inc.  5 nov 2007 –OHA formed  12 nov 2007-OHA released preview of the OHA android.  23 sep 2008- android’s first mobile lunched.  First product of OHA is android.
    • Versions version Code name 1.5 Cupcake 1.6 Donut 2.1 Eclair 2.2 Froyo 2.3-2.3.7 Gingerbread 3.1-3.2 Honeycomb 4.0-4.0.4 Ice Cream Sandwich 4.1 Jelly Bean

    • Android Architecture
    • Applcation -This layer is the top layer of the architecture. -In this layer we find application that ship with the android device application such as phone , contacts etc. -This layer also ship with the application downloaded from android market.
    • Application framework -Framework elements are-intent, content providers , views and manger. -this layer has been designed for facilitate the reuse of component in android.
    • Libraries This layer contains all the code that provides main features of the android OS.
    • Android Runtime -At the same level of libraries. - Application Developed language : Java -Dalvik Virtual Machine Instruction set : Dalvik Executable. -Java Standard Library Compile java code to Dalvik Executable
    • Linux kernal Android is based on the Linux Kernel. This layer contains the low level Device drivers.
    • Development tools  Eclipse  Android SDK  ADT  Emulator
    • Eclipse  As a IDE(integrated development environment) android use ECLIPSE.  Eclipse is multi language development environment, develop many applications using various languages such as java, c , cpp etc.  For android development we should have eclipse IDE for java EE developers.  Six editions are available such as windows(32 and 64 bit), Linux(32 and 64 bit) etc.
    • Android SDK  SDK stands for software development kit.  A SDK that enables developers to create application for the Android platform.  The Android SDK includes sample projects with source code , development tools, an emulator , documentation , tutorials and required libraries to build Android applications.  We can download SDK from http://developer.android.com/sdk/index.html
    • ADT  ADT stands for android development tools.  ADT plug-in for eclipse is an extension to the eclipse IDE that supports the creation and debugging of apps. Using ADT in eclipse we can(a) Create new android app. (b) Access the tools for accessing our android emulators and devise. (c) Compile and debug android app. (d) Export android apps into APK. 
    • Emulator Android application may be run on a real device or on the android emulator , which ships with the android SDK
    • DVM  DVM is open source software.  DVM stands for Dalvik virtual machine Google's Android operating system.  It is the software that runs the apps on Android devices.  Dalvik is thus an integral part of Android, which is typically used on mobile devices such as mobile phones and tablet computers.
    • Steps of creating new android project  To creating new android project select-project.  Give project name then select finish.  Then do coding in .java file, layout file, main XML file.  After completion project is ready to run on emulator.  Then run it thorough selecting run as –android project.  Then project runs on android emulator.
    • Activity  An activity is a single, focused thing that the user can do.  Almost all activities interact with the user, so the Activity class takes care of creating a window for us in which we can place our UI with setContentView(View).  Activity life cycle-Activities in the system are managed as an activity stack. When a new activity is started, it is placed on the top of the stack and becomes the running activity -- the previous activity always remains below it in the stack, and will not come to the foreground again until the new activity exits.
    • Phonebook  During my training I create android project “phonebook”.
    • Introduction to the project  This project aims at storing our important contacts on our android device.  This application is mainly designed for those who want to store there important contacts on their mobile device itself.
    • SOME SPECIAL FEATURES  We can create , delete , view and search our contacts which we have stored earlier.  It helps in easily remembering our important contacts which we want to use in our daily work.  In this project we can easily set our important contact details like birthday , email address , home and office phone number separately and much more .
    • SOME SNAPSHOTS OF THIS PROJECT – HOME WINDOW
