1.1.1 Getting Started_Budding Your First App_Creating an Android Project

• Minimum Required SDK is the lowest version of Android that your app supports, indicated using the App level. To support as many devices as possible, you should set this to the lowest version available that allows your app to provide its core feature set. If any feature of your app is possible only on newer versions of Android and it's not critical to the app's core feature set, you can enable the feature only when running on the versions that support it (as discussed in Supporting Different Platform Versions). Leave this set to the default value for this project.
• Target SDK indicates the highest version of Android (also using the App level) with which you have tested with your application.

  As new versions of Android become available, you should test your app on the new version and update this value to match the latest API level in order to take advantage of new platform features.

• Compile With is the platform version against which you will compile your app. By default, this is set to the latest version of Android available in your SDK. (It should be Android 4.1 or greater; if you don't have such a version available, you must install one using the SDK Manager). You can still build your app to support older versions, but setting the build target to the latest version allows you to enable new features and optimize your app for a great user experience on the latest devices.

 

所要求的最低SDK：这是你的app支持的最低版本的Android，版本用API level表示。你应该将它设置为能支持你的app的核心功能集的最低版本以支持尽可能多的设备。

目标SDK:表明你的应用测试通过的最高版本的Android。当有新版本的Adroid可用时，你应该在新版本下测试你的应用并更新这个值来适配最新的版本，这样做才能利用新平台的特性。
