在Android的AVD管理器（或者为此事一个新的项目），它会给两个选项相同的API级别。 例如，对于7级（2.1），将显示谷歌的API - 7级的 - 在选择Android 2.1的7级降下来了。 什么，如果有的话，就是这两个，我为什么要一个比其他？

In the Android AVD manager (or a new project for that matter), it will give two options for the same API level. For example, for Level 7 (2.1) it will show "Google APIs - Level 7" and "Android 2.1 - Level 7" in the selection drop down. What, if any, is the actual difference between these two and why would I want one over the other?

推荐答案

在谷歌的API包括一些谷歌应用程序，如谷歌地图的实例。如果你的应用程序将利用一些谷歌的API的话，当然，你想在模拟器中运行了谷歌阿比的。如果你不打算使用谷歌API的它肯定不会伤害你在模拟器中运行谷歌的API，所以这是一般我做什么。

The Google APIs include some Google apps such as Google Maps for instance. If your app will make use of some of the Google API's then of course, you would want to run the Google Api's in the emulator. If you aren't planning to use the Google API's it certainly doesn't hurt you to run Google API's in the emulator, so that is generally what I do.
