5. Android, Blackberry and J2ME uses Java Language for their development but their applications are not portable because of different hardware, SDK and API. Windows Phone 7 requires Windows Operating system for its development, the Visual Studio (only supported IDE for Windows Phone) and Emulator also works only in Windows environment. C# is the language of Windows Phone 7 which is not used by any other platform. iPhone requires Macintosh Operating System and XCode is the IDE for iPhone. Objective C is used for the development of iOS

6. Native vs hybrid vs web mobile Application
Application Development For mobile Devices

7. A primary reason that many companies are not already jumping on the HTML5 bandwagon is the belief that HTML apps cannot access native device features. Indeed, pure mobile web apps (i.e., those that run in the browser – not hybrid ones) are currently restricted in their access to features such as the camera, microphone, address book, and so forth. And while there is work in progress at the W3C to allow web apps to access such device services, mobile browsers do not currently provide such functionality – a key requirement for many innovative mobile apps.
Access to device features is not the only difference between hybrid apps and mobile web apps. Another important difference is that hybrid apps are mostly distributed through app stores: You don’t browse to a hybrid app – you download and install it.

8. Native app
A native application works only on the platform for which it was created
Native apps were originally developed by Apple, which had various programs built in Objective C to run specifically on their mobile OS. Later, Android developed their native apps in Java, which worked only on the Android platform.

9. Mobile web apps
Web Applications – Designed to Operate on Multiple Platforms
Web apps, however, do not connect with native apps and cannot make use of APIs or native hardware features like cameras and microphones. Consequently, many companies are reluctant to fully convert to HTML 5.

10. Mobile hybrid app
A Hybrid app is a native app operating within a web browser
It provides the same functionality and efficiency for the user, but saves the developer from the tedious process of creating multiple native apps for a single project
Industry experts predict HTML5 will become more prevalent because of its versatility and efficiency

11. Mobile Web Development javascript frameworks
jQuery Mobile jQuery Mobile, a framework that will help you rapidly and confidently develop mobile app user interfaces across popular mobile device platforms like iOS and Android, is perhaps the most popular project out there.

12. Mobile Web Development javascript frameworks
Titanium Mobile This powerful and robust mobile web development framework allows you to use your existing HTML, CSS and JavaScript knowledge to make native-like mobile apps for iOS and Android.
M-Project The-M-Project is another solid JavaScript framework that takes advantage of new HTML5 features for easier and better mobile app development.
The framework follows the popular model-view-controller (MVC) software architecture pattern, which is a huge selling point for many developers.

13. PhoneGap
PhoneGap is opensource mobile development framework to build mobile application using javascript,HTML5 ,and CSS3.
The resulting application will by hybrid
Neither it would be native nor it is web based.
PhoneGap is an open source platform that allows you to create cross-platform mobile applications with HTML, JavaScript, and CSS
In order to interact with device hardware, PhoneGap provides a JavaScript API that will interface with features such as the on-board camera, GPS, and accelerometer
Supported features
PhoneGap currently supports development for the operating systems Apple iOS, Google Android, HP webOS, Microsoft Windows Phone, Nokia Symbian OS and RIM BlackBerry
Why phoneGap
Mobile development is a mess. Building applications for each device--iPhone, Android, Windows Mobile and more--requires different frameworks and languages. One day, the big players in mobile may decide to work together and unify third-party app development processes. Until then, PhoneGap will use standards-based web technologies to bridge web applications and mobile devices. Plus, because PhoneGap apps are standards compliant, they’re future-proofed to work with browsers as they evolve.

19. Android Software Development
Android software development is the process by which new applications are created for the Android operating system. Applications are usually developed in the Java programming language using the Android Software Development Kit,

20. Introduction
Android is an operating system based on Linux with a Java programming interface.
The Android Software Development Kit (Android SDK) provides all necessary tools to develop Android applications. This includes a compiler, debugger and a device emulator, as well as its own virtual machine to run Android programs.
Android is officially guided by the Open Handset Alliance. In reality Google leads the project.
Android allows background processing, provides a rich user interface library, supports 2-D and 3-D graphics using the OpenGL libraries, access to the file system and provides an embedded SQLite database.

21. Open handset alliance
The Open Handset Alliance (OHA) is a consortium of 84[ firms to develop open standards for mobile devices
Welcome to the Open Handset Alliance™, a group of 84 technology and mobile companies who have come together to accelerate innovation in mobile and offer consumers a richer, less expensive, and better mobile experience. Together we have developed Android™, the first complete, open, and free mobile platform.

22. introduction What is the Open Handset Alliance (OHA)?
It's a consortium of several companies

23. History of Android
The OHA was established on 6 November 2007, led by Google with 34 members including mobile handset makers, application developers, some mobile carriers and chip makers. Android, the flagship software of the alliance, is based on an open source license and competes against mobile platforms from Apple, Microsoft, Nokia (Symbian), HP (formerly Palm), Research In Motion, and Samsung Electronics (bada).

27. Android Application Development Process

28. How mobile application runs

29. The APK
An application is a single APK (application package) file. An APK file roughly has three main components. It consists of all your Dalvik executable code (Java code compiled automatically to Dalvik executable) plus all your resources (everything that is not code, such as images, layouts, etc.). Additionally, it may contain some native code as well.
Dalvik executable: this is all your Java source code compiled down to Dalvik executable. This is the code that runs your application.
Resources: resources are everything that is not code. Your application may contain number of images, audio/video clips, as well as numerous XML files describing layouts, language packs, and so on. Collectively, these items are resources.
Native libraries: optionally, your application may include some native code, such as C/C++ libraries. These libraries could be packaged together with your APK file.

30. Intro to development framework
Android applications are written with java as programing langurage but executed by a custeom virtual machine called Dalvik rather than by a java VM.
Each android application runs in a separate process with in its own Dalvik instance ,relinquishing all responsibility for memory and process management to the Android run time,which stops and kills process as necessary to manage the resources

31. continued
Dalvik and android run time sits at the top of the linux kernel that handles the lowlevel hardware interaction,including the drivers and memory management ,while a set of APIs provides access to all the underlying services ,features and hardware.

32. Installation

33. Step 1
To get started you need to download and install the following
The Android SDK
Java Development kit ( 6)
You can download jdk 6.0 from here

34. (Step 2)Download and installing SDK
Android development home page
You need atleast on SDK platform ,you can do this ,you can do this by on Windows by running SDK Setup.exe.

35. Step 3:-
You have to download eclipse with ADT plug-in
To download the eclipse

36. Using the eclipse plugin
The ADT plugin for elipse simplifies your Android development by integrating the development tools directly into IDE,

37. Installing ADT Plug-in

39. If you are behind a firewall (such as a IBA firewall), make sure that you have properly configured your proxy settings in Eclipse. In Eclipse, you can configure proxy information from the main Eclipse menu in Window >Preferences > General > Network Connections.

40. Window > Preferences> Android
modify your ADT preferences in Eclipse to point to the Android SDK directory:(very important)

41. Create Android Virtual Device(AVD)

42. Creating your first Android Application

52. The template “Iba_World, created by the wizard
overrides the onCreate method to call the setContentView,which
lays our her interface by inflating a layout resource.

53. The resource of an android project are stored in res folder of
your project hierarchy,which includes drawables,layouts,values.
The ADT Plugin interprets these resources to provide design time access to them through R variable

55. Defining your UI in XML and inflating it is the preferred way of implementing
your user interfaces, as it neatly decouples your application logic from your UI design.
To get access to your UI elements in code ,you add identifier attributes to them in
the XML definition.
You can then use the findViewById method to return a reference to each nameditem.

56. How to access it into the code
TextView text = (TextView) findViewById(R.id.myTextView);
