Android Aims to bring Internet-style innovation and openness to mobile phones

You might help me to figure it out… What is the limitation of Windows Mobile? What are the advantages of Java & Linux? What you think when you purchase any mobile phone?

What it is??? Software Environment for Mobile Devices contains Operating System, middleware and bunch of applications First complete, open and free mobile platform Based on Linux Kernel Uses Java as a development Language…. By Google later Handed to Open Handset Alliances Google doesn’t left anything in technology world without it magic touch……

Why Special ??? Application framework enabling reuse and replacement of components Dalvik Virtual machine optimized for mobile devices Integrated browser based on the open source WebKit engineWebKit Optimized graphics powered by a custom 2D graphics library; 3D graphics based on the OpenGL ES 1.0 specification SQLite for structured data storage Media support for common audio, video, and some image formats (MPEG4, H.264, MP3, AAC, AMR, JPG, PNG, GIF) GSM Telephony,Bluetooth, EDGE, 3G, and WiFi, GPS,Compass,Accelerometer (hardware dependent) Rich development environment including a device emulator, tools for debugging, memory and performance profiling, and a plugin for the Eclipse IDE

This for Users……Lots of cool stuff from Google Multiple applications, running all at once, and switch seamlessly between them. Notifications alert you when applications running in the background require your attention. Demo :- The native WebKit browser lets users experience the "full web" and easily move between browsing and other tasks on their phone. Demo :- Personalize the home screen to suit your needs and tastes. Demo:- Application without Borders Any app on the mobile device can be replaced or extended Fast scrolling……. Browser Trick……Easy Copy & Paste………Contact & Calendar……………long & long list

This for Developers….

Open Market Developers will be able to make their content available on an open service hosted by Google that features a feedback and rating system similar to YouTube.

Write the steps for Text Messaging Program Consider yourself as a developer not as a user…. What are the functions/Events you need? Who start/stop/switch? What is Scenario? From where it comes and where it goes?

Anatomy of Android Application – Text Messaging Example Activity – Single class, Single Screen composed of views, respond to user input Intent –Navigation from Screen to Screen Broadcast Intent Receiver – Notification, request Service – long-lived, running in background Content Provider – Standard set of methods to store and retrive data AndroidManifest.xml – required file for every application

First Simple Application package com.android.hello; import android.app.Activity; import android.os.Bundle; import android.widget.TextView; public class HelloAndroid extends Activity { /** Called when the activity is first created. public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); TextView tv = new TextView(this); tv.setText("Hello, Android"); setContentView(tv); }

Confusion about how to start ??? Here is the answers…. Tools APIs – es.html Project

At Last………..Criticism Google announce it is open source but license says……. 3.2 You agree that Google or third parties own all legal right, title and interest in and to the SDK, including any Intellectual Property Rights that subsist in the SDK. "Intellectual Property Rights" means any and all rights under patent law, copyright law……………………………… Use, reproduction and distribution of components of the SDK licensed under an open source software license are governed solely by the terms of that open source software license ……….. Google releasing code under Apache 2 licenses rather than GPL2………Why ????? Android only reuses the Java language syntax, but does not provide the full-class libraries and APIs bundled with Java SE or ME

Thanks to References…… Lots of Blogs…
