Google's next version of the Android operating system firmware, Version 2.2, codenamed "Froyo", apparently has made great progress. We have already published many articles discussing its greatness. But I have read enough related articles. Why don't I try it on my own?

Previously, a Nexus One user reported to us that froyo can be updated, but not everyone has a Nexus One phone. However, any mobile phone operating system will have an SDK, the developer kit, which allows developers to create and test software on the relevant platform. In addition, any excellent SDK will bring a mobile phone OS simulator, so that developers can test the software on the computer, instead of having to install it on the mobile phone. Apple's iPhone has a simulator, but it can only run on Macs. Microsoft's simulator can only run on PCs. Google's Android simulator can run on any platform and is completely free of charge. The following describes how to set up Android froyo on your computer in just a few minutes.

How to Set up a simulator

First, you must:
• Android SDK (for Windows or Mac)
• A powerful enough computer (netbook simulating a smartphone)
Then:

1. decompress the android SDK. You should see a bunch of folders and files, including platforms, add-ons and tools.

2. Open a program or script called Android in the Tools Folder to open the SDK manager.

3. In the program manager, click available packages in the list on the left. A download list is displayed, which is only a software library, download it will give you a new download option, so proceed.

4. In the new download list, select and download four items (this takes some time, you are downloading the real mobile operating system and some other tools ).

5. After the download and installation are complete, return to the Manager homepage, select "Virtual Devices" on the left in the right window, and click New.

6. In this window, you can set parameters for simulating Android phones. Aside from the mandatory target settings of Android 2.2, there are not many places to set. You can set a virtual SD card. While the screen resolution does not have to choose the highest option (WVGA 854), it indicates 854 pixels high, if your computer is a MacBook or another wide screen netbook, it may exceed the screen resolution of your computer.

7. Click Create AVD. Your computer may be suspended for several seconds. The program may not respond. It doesn't matter. Please wait patiently.

8. Now you have a virtual Android phone under virtual devices. Select your phone and click Start. (It may take some time to start. If the device has not been started after two or three minutes, try again, or follow the previous steps to create another virtual device .)

Now, you have used Android Froyo! Look around.

Ah, where is the application?
That's right. Now you have a pure Android 2.2 System. Is the original, open-source core mobile phone operating system, called android2.2. However, it still lacks many widgets, including many closed source programs, such as Google Maps. You cannot test the flash function, but fortunately you can install other programs of all types. The methods provided by Google are as follows:

1. Download a development tool named eclipse (use this link http://www.eclipse.org/downloads/, you will get a Java Development IDE)
2. Install Android development components in eclipse
Http://developer.android.com/sdk/eclipse-adt.html
3. Direct the android development component to the android SDK folder (the directory where you previously decompressed the SDK ).
4. Import and run the Android Application. (You can search for the desired androidprogram file on your own network, in the format of .apk. Many websites have their own Android Market ).
