Title: What is Android?

What is Android?
Android is a software stack for mobile devices.
The Android SDK provides the tools and APIs
necessary to begin developing applications on the
Android platform using the Java programming
language. Android delivers a complete set of
software for mobile devices. The software
includes an operating system, middleware and key
mobile applications. Middleware is computer
software that connects software components or
applications. The software consists of a set of
services that allows multiple processes running
on one or more machines to interact.   In July of
2005, Google acquired Android, Inc. a small
company based in California, USA. When Google
took over little was known about the function of
Android, Inc. the only thing that was known was
that they made software for mobile phones. Today
we see that Google has been very busy
incorporating the use of Android to create a new
hot mobile phone which is now available through
T-mobile. The very first phone to run the Android
Operating System was the HTC Dream, which was
released very recently on October 22, 2008.

New to Android?
Android uses the java programming language and
for anyone who has learned Java the Hello World
example is a good reminder of that very first
class or online tutoring session. First you will
need to download the Android SDK kit and if you
are using Eclipse install the ADT Plug-in, this
is very easy and all of the information you need
to do this can be found at http//developer.andro
id.com/sdk/index.html. Below is an example of the
Hello World program. You will see that the coding
is similar to that of java but not exactly the
same. You can also see that it is fairly simple
and this makes everyone happy ?
package com.example.helloandroid import
android.app.Activity import android.os.Bundle
public class HelloAndroid extends Activity
/ Called when the activity is first created.
/ _at_Override public void onCreate(Bundle
savedInstanceState) super.onCreate(savedInst
anceState) setContentView(R.layout.main)

Running your application
  • If you decide to use Eclipse (probably your best
    choice) the ADT plug-in that you
  • install makes it very easy and simple to run your
  • Select run -gt run
  • Select Android Application

The Eclipse ADT will automatically create a new
run configuration for your project and the
Android Emulator will automatically launch. Once
the emulator is booted up, your application will
appear and should look like this
You can see that this process is very Simple,
quick, convenient and easy. This is one reason
why Android is such a great Application
development kit. If you prefer not to use
Eclipse don't worry because the Android SDK
includes a tool named "android" that can be used
to create all the source code and directory stubs
for your project, as well as an ant-compatible
build.xml file. This allows you to build your
project from the command line, or integrate it
with the IDE of your choice. So many Options!!!

In conclusion, Android seems to be the future of
mobile OS's and mobile software Development. In
today's increasingly complicated technology this
OS just adds to all of the fun, making phones
cooler and development easier. It also seems as
though Android could easily move its way into the
market from phones to netbooks and desktops as
developers become more accustomed with it, and
this will only create more business. Currently
there are about 20 Android phones available on
the market with more than 75 million Android
handsets forecasted by 2012. This statistic is
very impressive and proves that there is indeed
a bright future for Android. Since Android is
an open source (meaning it is available to
anyone) developers and handset manufacturers have
full access to it. This means that developers and
manufacturers all over the world are taking
advantage of the Android operating system. This
also means that the Business should grow very
rapidly! Go Android Go!!!!!!!!
