What Is Android

Before we begin to be an android developer we should know what is Android, Theres a thousand of books explaining about this but let me give a litle bit intro.Okay,Android is one of many system operation that runs on linux kernel and it design for smartphone.Android is a open source platform( open source means that everyone can take contributions to be some android developer.
Now the question is why Android is a the best operating system that we choose,well this is why :

1. Complete platform ; so many tools will help you
2. Open source ; feel free to create
3. Free ; this is my favorite,no cost for license

Doesnt care if youre an experienced programmer or beginner, a desktop or web developer, or a complete programming novice, Android represents an exciting new opportunity to write innovative applications for mobile devices.
Despite the name, Android will not help you create an unstoppable army of emotionless robot
warriors on a relentless quest to cleanse the earth of the scourge of humanity. Instead, Android is an open source software stack that includes the operating system, middleware, and key application and function of mobile handsets.
Small, stylish, and versatile, modern mobile phones have become powerful tools that incorporate cameras, media players, GPS systems, and touch screens. As technology has evolved, mobile devices have become about more than simply making calls, but their software and development platforms have struggled to keep pace.
Until recently, mobile phones were largely closed environments built on proprietary operating
systems that required proprietary development tools. The phones themselves often prioritized
native applications over those written by third parties. This has introduced an artificial barrier
for developers hoping to build on increasingly powerful mobile hardware. Ground services, map-based activities, relational databases, interdevice peer-to-peer messaging, and 2D and 3D graphics.

What Was NEC Thinking

It’s not every week that I have two tablets I can point at and say “that’s how not to do it” but after Monday’s post about the Toshiba Folio 100, I have another device I want to point out that just plain gets it wrong.

And while Toshiba at least had good intentions with their Folio design, NEC has completely missed the boat when it comes to their newest tablet entry – the LifeTouch. The device, which on paper doesn’t sound bad with Android, 3G, USB, SD Card reader, and 3 megapixel camera, all running on an ARM Cortex, is just a bit clunky if you ask me.

Here’s the problem. As you can see from the image above, not only does the LifeTouch eschew the increasingly standard silvers and blacks of modern tablets for a bright, glossy white, it is loaded with clunky buttons, a whole lot of extra material and a 7 inch touch screen that looks smaller than it ought to.

Just after receiving news that in the US alone, Samsung has sold 600,000 Galaxy Tabs, we now know that there is a huge market for Android tablets, but devices like this aren’t designed to capture that audience.

To be fair, it’s not like no other devices look like the LifeTouch. Only three years ago, many devices still sported buttons and had thick, heavy bodies for carrying. The difference is that back then touch screens simply lacked the responsiveness and flexibility they have today. And Windows on tablets was still being done with modified XP installations – it wasn’t nearly optimized for touch screen yet, so you needed buttons.

But, today’s devices are sleeker and more efficient than ever. Touch screen has moved forward at rapid speed and Windows is now a hot commodity for enterprise tablets (which is the market the LifeTouch is aiming for). And, this isn’t even a Windows device. It’s Android which means it was built for touch screens – definitely no reason for buttons.

In the end it all comes back to one question – what exactly was NEC thinking? Not only will this device launch at the tail end of the biggest year for tablet computers ever to date, but it will be immediately hobbled by questionable design, an older version of Android (2.1), and no clear market.

The last two years has been an amazing time for anyone who follows tablet computing. The speed with which the market has moved forward still astounds me and the new technology and sleekness of some devices being announced is downright impressive, but every now and then someone gets it wrong. It’s not to say a future device from NEC won’t adopt a sleeker design and a more intuitive layout, but for now we’re getting one more lesson in how not to build a tablet in 2010.
