这是android的sdk开发库,是支持java的.android-sdk-linux_86-The Android SDK archive now only contains the tools. It no longer comes

populated with a specific Android platform or Google add-on. Instead you

use the SDK Manager to install or update SDK components such as platforms,

tools, add-ons, and documentation.



In order to start developing applications, you must install at least one

version of the Android platform using the SDK Manager.



This requires an Internet connection, so if you plan to use the SDK

offline, please make sure to download the necessary components while online.



To start the SDK Manager, please execute the program "tools/android".
