Android SDK 2.2 Development Environment

Google held the second day of the Google I/O 2010 Conference at the Moscone township International Expo Center in San Francisco (October 11, May 20) the latest version of Android 2.2. The next step is to download the SDK (developer kit) installation package on the network. Although the SDK package alone cannot allow us to experience applications such as flash10.1, according to the official introduction, the new version of the system greatly improves the performance. In addition to supporting flash 10.1, the system interface and functions are also optimized in detail.

Android 2.2 is very much worth looking forward to. The following are detailed steps for configuring the android sdk2.2 + Eclipse open environment based on my practical experience. These steps can also be completed by outsiders.

System environment requirements can refer to the http://androidappdocs.appspot.com/sdk/requirements.html

(3)Android SDK

To be precise, the download is not an SDK but an SDK download Installer. Because the download is not an SDK, you need to connect to the official website to download the required SDK.

Download http://androidappdocs.appspot.com/sdk/index.html and select the download path of the Windows platform. The latest version is android-sdk_r06-windows.zip, which is about 22 MB. Decompress the package.

2. Set the development environment

(1) Download and configureSDK

There are two configuration methods,

First, use the SDKThe download tool automatically downloads and configures the file. Suitable for scenarios where the network is good and the download speed is fast.

Second, download the SDK using toolsFile. Suitable for scenarios where the network is not good and the download speed is slow.
