关注了一个多月的Android手机，从HTC的Desire到SE的X10，以及三星的i9000，还有Moto的Milestone，终于等到了搭载Android 2.3的新机——三星Nuxus S.

The latest hardware meets amazing software

Android 2.3，Gingerbread，也叫姜饼。Nexus S则是第一款搭载姜饼的官方硬件产品。这款手机将为用户提供多任务处理能力、WiFi hotspot功能和全新的用户体验，此外还有改进的键盘、Near field communication (NFC)等。

         

Refined look and feel

多数人认为Google的Android在用户界面方面一直比较落后，Geek气息比较厚重，用户也以比较专业的用户为主。虽然还没看到2.3的面貌，但是想必也是有重大突破，否则也不可能摆在四个重要Feature之首。

Internet calling (VoIP/ SIP support)

这个可是重度挑战电信运营商的功能，也注定了在中国大陆无法上市。不过就这个功能本身而言，对用户来说真的会是非常方便，如果用户有包月的数据业务，结合先前的Google Voice，虚拟的美国电话号码，虽然通话质量比Skype还是差不少，在新平的支持下，应该会有所提升。

One-touch word selection and improved copy-paste

复制粘贴是手机操作长久以来的痛，模仿PC鼠标的复制粘贴对手机来说实在是不好用，Android 2.3提供了新的文本选择工具。

Portable Wi-Fi hotspot

Nexus S允许最多六个移动设备与自己连接共享网络连接，把自己变成一个无线路由。实用并且重要的功能，但是估计费电不小吧。

此外Nexus S拥有4寸400×800的屏幕，材质是Super Amoled，三星的产品再不用自家最牛逼的屏幕就说不过去了。1G的处理器和16G的内存以及独立GPU决定了这款机器的不凡性能。

这款手机上市后在Bestbuy的售价为529美元，对于性能了得的Nexus S来说不算贵了，和HTC Desire相比，无论是工业设计、硬件性能都有过之而无不及。根据官方发布的消息，12月16日之后，这款手机将在美国上市，随后12月20日在英国发布。

For the last two days, I’ve been trying from installing Android on my Samsung i900 phone to setting up an Android Emulator on my Windows 7 laptop. I even almost make my decision to buy an Android smartphone. But eventually, all I want is to try out Android amazing apps in Android Market. That’s all because of no listing available to normal PC browsers. And the standard Android Emulator doesn’t contain the Market.

Finally, I found a way to run Market on Android Emulator. It’s actually easy but a little bit tricky – to replace standard Android SDK system.img with a developer image from HTC developer website. I will show you now.

Step 1. Install Android SDK on your OS. I did this on my windows 7.

Visit Google Android Developers at http://developer.android.com/sdk/index.html and download the SDK installer.

Then you need to first download SDK packages. When you start the SDK manager, it will prompt to download or update SDK packages. Just follow the instruction. It will take a while because about 800M data need to be downloaded totally, including all SDKs from Version 1.5 to 2.2.

Step 2. Create a Virtual Devices.

Choose a target system of Android 1.6. Because on the HTC developer website, only 1.5 and 1.6 system images are available to download.

Step 3. Download HTC Developer system image.

Visit the website: http://developer.htc.com/adp.html and scroll down to section“Download the Image Packages”. Download the one I marked in the screen shot below.

Step 4. Copy system.img to your virtual device folder.

Extract the system.img file from the downloaded zip file. Copy it to your virtual device folder – located in <username>/.android/avd/<avdname> . By default, Android Emulator will load a default system.img from SDK folder. But when you copy your downloaded system.img to the AVD folder, it will use this one.

Finally, start your virtual device and setup your personal account if it’s the first time using the virtual device. Then you will see the market on the “desktop” of your Android.

It’s really cool because I don’t need to buy an Android phone just for try out apps. Just enjoy it.

In this tutorial, I will show you how to install and remove applications (APK files) on the Android Device Emulator which is bundled as part of the SDK. If you are a developer, you may often want to install applications on the Android Device Emulator for testing before you publish them. You may also want to run certain applications on the emulator before installing them on your device.

To install / remove applications on the Android Device Emulator, you need to download and install the SDK from http://developer.android.com/sdk/. After downloading the file, just extract the archive into any folder. You won’t need Eclipse or any IDE.

Before installing / removind apps on the emulator, you should also set the PATH environment variable to point to the tools directory in the Android SDK directory so that you can use ADB directly on the command line.

To do so, go to My Computer – > Right Click – > Properties – > Advanced – > Environment Variables. Select the PATH variable from the System Variables and click Edit. Add the location of the tools directory to the existing string. Ex: C:\Android\Tools and save the changes.

Installing APK Files on the Android Device Emulator.

Now download the APK file you want to install and save it in the tools directory (preferably).

Open Command Prompt by Start – > Run – > CMD and navigate to the tools directory.

type: ADB INSTALL APKFILE.APK where APKFILE.APK is the name of the application you want to install.

If there are no errors, then the application has been successfully installed. You can now just run the emulator directly to access it.

Removing APK Files from the Android Device Emulator.

To remove the installed APK files,

Just go to Command Prompt by Start – > Run – > CMD and navigate to the tools directory.

type: ADB SHELL RM DATA\APP\APKFILE.APK where APKFILE.APK is the name of the application you wish to remove.

If there are no errors, the application has been removed.

Android自上市以来在和iPhone走了完全不同的两条路，Google把手机制造的业务留给了行业上游，自己则获得了最重要的平台、用户以及渠道资源。在2009年Q3，Android市场占有率仅为3.5%，而一年之后的2010年Q3，Android的市场占有率已经达到25.5%。也许明年的Q3，Symbian也要被轻松超越。

Gartner在报告中指出，Android在全球范围内的市场占有率已经非常惊人，但是在北美更是具备主导地位。有趣的是，Gartner说，Android在Q3的成功要归功于iPhone 4，看来iPhone 4的确是不那么乐观。

从这张表格中我们可以看到，Android OS在智能手机市场上是一年以来唯一增长的产品，这说明Android的强势蚕食了市场上所有的竞争对手，四面树敌的Android在接下来一年恐怕不好过了。
