OHA is a business alliance of 78 firms for developing open standards for mobile devices. Member firms include Google, HTC, Dell, Intel, Motorola, Qualcomm, Texas Instruments, Samsung, LG, T-Mobile, Nvidia, and Wind River Systems. What is Android..?? Android is an open source* software platform and operating system for mobile devices initially developed by Android Inc. - a firm purchased by Google in year 2008. Android is based on the modified version of Linux Kernel and is a participant in Open Handset Alliance. It allows developers to write managed code in a Java-like language that utilizes Google-developed Java libraries, but does not support programs developed in native code.

What is Android..? (contd.) Android is an open source* Operating System for mobile phones Released by Google and the Open Handset Alliance for smartphones. 3 Software Project Management Presentation :: Android Experience What we need to Remember..?? http://www.openhandsetalliance.com/

What are Smartphones..? Smart Phone (Mobile Phone + PC Like functionality) Manages our personal life, work life & communication As available as possible Hell lot of applications Getting Cheaper.. ;) **Smartphones will double their share of all cellphones to about 20 percent in the world And by year 2011,it is expected to have more number of smartphones in U.S. than feature phones.. Let’s see how.. 4 Software Project Management Presentation :: Android Experience ** http//:www.in-stat.com

Software Project Management Presentation :: Android Experience 14 1. Android is open.. http://code.google.com/android/goodies/index.html Well, Sort of.. Summary: Android Advantage

Software Project Management Presentation :: Android Experience 15 2. Android makes mobile Java easier http://code.google.com/android/goodies/index.html Android Advantage (contd.) Android provides access to a wide range of useful libraries and tools that can be used to build rich apps.

Software Project Management Presentation :: Android Experience 16 Write app in Java Compiled in Java Transformed to Dalvik bytecode Android Advantage (contd.) 3. Applications are compiled to Dalvik byte code

Software Project Management Presentation :: Android Experience 17 The Dalvik runtime is optimized for mobile applications Run multiple VMs efficiently Each app has its own VM Minimal memory footprint Android Advantage (contd.) Breaking down application boundaries: Android breaks down the barriers to building new and innovative applications. For example, a developer can combine information from the web with data on an individual's mobile phone -- such as the user's contacts, calendar, or geographic location -- to provide a more relevant user experience.

Breaking down application boundaries:

Software Project Management Presentation :: Android Experience 19 Android is designed to enable reuse of components in other applications Each application can publish its capabilities which other apps can use 5. All applications are written in Java and available to each other Android Advantage (Summary)

Android SDK includes a virtual mobile device - Lets you prototype, develop, and test Android applications without using a physical device. GPS support Wi-Fi support File explorer Software Project Management Presentation :: Android Experience 20 6. Android has Working Emulator Android Advantage (contd.)

Software Project Management Presentation :: Android Experience 21 Android Applications have common structure Views such as lists, grids, text boxes, buttons, and even an embeddable web browser Content Providers that enable applications to access data from other applications (such as Contacts), or to share their own data A Resource Manager, providing access to non-code resources such as localized strings, graphics, and layout files A Notification Manager that enables all apps to display custom alerts in the status bar An Activity Manager that manages the life cycle of applications and provides a common navigation backstack

Software Project Management Presentation :: Android Experience 22 Content Provider enable applications to share data. Service is a faceless task that run in the background Intent Receiver responds to notifications or status change. Can wake up your process Activity is UI component typically corresponding to one screen. Android Applications have common structure

Let’s feel the Android.. ;) Software Project Management Presentation :: Android Experience 25

Common File Structure Software Project Management Presentation :: Android Experience 26 code images files UI layouts constants Auto generated resource list

Software Project Management Presentation :: Android Experience 27 Standard components form building blocks for Android apps Other applications Has life-cycle screen App to handle content Background app Like music player Views manifest Activity Intents Service Notifications ContentProviders

Activity is one thing you can do.. Activities have several states. Lifecycle methods are called on transitions. You typically don’t need to use them all, but they are there! 28 Software Project Management Presentation :: Android Experience From fundamentals page in sdk

Software Project Management Presentation :: Android Experience 29 Nos. Increasing rapidly..

Services declared in the manifest and provide support Services run in the background: Music player providing the music playing in an audio application Intensive background apps, might need to spawn their own thread so as to not block the application

Notifications let you know of background events This way you know that an SMS arrived, or that your phone is ringing, and the MP3 player should pause Notifications

Content Providers Software Project Management Presentation :: Android Experience 32 Content Providers share data You need one if your application shares data with other applications This way you can share the contact list with the IM application If you don’t need to share data, then you can use SQLlite database

Software Project Management Presentation :: Android Experience 33 UI layouts are in Java and XML setContentView(R.layout.hello_activity); //will load the XML UI file

Software Project Management Presentation :: Android Experience 36 SQLite: easier to setup great for temporary (testing databases) great for rapid development great for embedding in an application not fit for production (in large scale) doesn't have user management doesn't have many performance features doesn't scale well.
