Android is a mobile operating system primarily designed for mobile phones. Android was the first complete, open, and free mobile platform and runs on the Linux kernel. It was launched on 5 November 2007.




It was initially developed by Android Inc., a firm later purchased by Google, who then transferred further management and development of the operating system to the Open Handset Alliance™. The Open Handset Alliance is a group of 65 technology and mobile companies who have come together to accelerate innovation in mobile platforms and offer consumers a richer, less expensive, and better mobile experience.
Various companies, including Motorola, Samsung and HTC, are commercially deploying handsets and services using the Android Platform.
Android enabled mobile phones (and even netbook computers) provide many functions equivalent to desktop and laptop computers but use a fraction of the power, so they are a welcome innovation in support of green computing.
Android is designed to integrate with “cloud computing” services provided by Google and possibly others. This means that your data is stored in the cloud as well as your handheld device. If you lose the device your data is safe “in the cloud”. This also means that you no longer have to sync with a specific desktop or notebook computer, unlike the iPhone which requires you to sync with iTunes on another computer to load digital content such as music and videos.
Development environment
The Android SDK is a free development environment which can be downloaded for Linux, Windows or Mac OS-X platforms. It allows developers to write managed code in the Java language, controlling the device via Google-developed Java libraries.
Most of the Android code is available under the Apache License, a free software and open source license.

User experience
The following user experience provides some information on the functionality and performance of the Android platform.
Comparison with iPhone
I had looked at the HTC Magic Android phone for a few months and was impressed by its look, feel and function. We bought an iPod Touch for our Europe trip in September 2009 because it was easy to load videos for our daughter to watch and its browsing and email functions (via Wifi) were easy and convenient to use. However, I find the following features of the iPhone limiting and/or frustrating:
- You have to load content via iTunes software running on a notebook or desktop computer
- You have to provide Apple with your credit card details to download free applications from the Apple store.
- The single select/exit button dumps you out of apps; it is not easy (or possible) to switch between running apps
- iPhone and iPod Touch devices are fairly expensive, and the software on them is proprietary, even though it is based on Unix.
- iPhone and iPod Touch devices have features disabled on them which appears to be a marketing ploy by Apple to “roll out new features” when in fact they are often just enabling them via software.
I decided to buy an HTC Magic on eBay in November 2009 and give Android a go.
First impressions
The phone is easy to use, the screen has a good resolution, the screen keyboard works surprisingly well. I found the response times reasonable to good. Accessing Google services such as email and calendar is quick and easy. You enter your gmail address and password and everything just works. The menus are easy to navigate and access.
Ergonomics
The HTC Magic fits in my pocket well. I also wear it in a neoprene belt pouch for easy access. The phone has a slight curve at its base which makes it easy to grasp and handle.
Features I like
- Control buttons – home, menu, back, search, make call, end call/exit app are easy to access and work as expected.
- Track ball – very handy when editing text and navigating web pages to select hyperlinks.
- The form factor is good- the curve on the bottom of the phone makes it easy to grab and handle and the phone fits easily into pockets or a small belt pouch.
- Predictive text is excellent – word options are presented as you type which can be selected.
- Gmail and Google calendar and gmail contacts integration is excellent
- Automatic hyperlinks from calendar and contact addresses to Google maps and GPS funtion
- Searches (accessed by the Search button) are relevant to the app you are in (browser, contacts, gmail etc)\
- The camera works well
- You can tether the phone and use it as a modem to access the Internet from a connected PC (via the PDANet application)
- Standard micro USB connector for charging and/or connecting to a PC
- Easy access to device content via USB “Mount” option which creates a USB drive for the device
- Standard Micro SD card support – provides cheap upgradeable and transferable storage
- User replaceable battery
- The battery life is reasonable. The battery will last 3 to 4 days if lightly used, but only 1.5 days if heavily used
- The Android market place for applications is easy to access and provides a wide assortment of useful applications
- The screen gestures are easy and effective to use; swipe to scroll, zoom in/zoom out controls work well
- The lock screen pattern is easy to set up and use and hard for others to crack.
- The flick down status bar gives quick and easy access to recent events (SMS message, app updates etc.)
- The three home screens are easy to customise and add/remove/move apps and widgets from, and you can add as icons:
- a URL for a commonly accessed website
- an application shortcut
- a widget
- a direct dial phone number (from your Contacts)
- Keyboard shortcuts such as
- Long press of Home button to get recently used apps
- Long press of End call key to bring up menu with Silent Mode / Airplane Mode / Power off options.
- Configure Google contacts to
- Provide access to specific groups
- Only display contacts with phone numbers
- Display “starred” contacts only
Missing features and short comings
- The HTC Magic phone supplied by Vodafone Australia has standard Android voice control function removed from its Android 1.6 operating system. I have installed Google voice libaries and can do Google searches and even find contacts by voice, but not dial them. This is inferior to the voice control and dialling that my Nokia 6120 phone has.
- No camera zoom. Later versions of Android support this but the handset must also support zoom functions. I can live without this.
- Searching for a contact is restricted to the contact name only. This is a major limitation compared to older PDAs such as Palmpilots which support searching all informtion for contacts including notes, address information and phone numbers. Hopefully this will be addressed in later versions of Android.

Setting up Android 1.6 on an HTC Magic
If you get the phone from your network provider it will work out of the box with no technical setup. Later versions of Android (4.0 ICS and later) configure their own settings. Earlier versions required some setup by the user.
The HTC Magic phone (running Android 1.6) I purchased was for the Vodafone Australia network and had no carrier (APN) information loaded in it. After some research on the Internet and a few calls to “3” (my mobile phone company) I was able to get the phone working.
The main challenge is to find out the APN (Access Point Name) settings for your carrier if you don’t get the phone supplied by your carrier.

For the 3 network in Australia you need these two:
- Name: 3Internet
