我们建议您在安装ADT套件，更容易发展。这些步骤的其余部分均假定你安装了这个。单击窗口> Android SDK中管理器。安装Android 4.0.3（API 15）的SDK平台和谷歌GDK先睹为快。一切是可选的。

We recommend installing the ADT Bundle for easier development. The rest of these steps assume you have this installed. Click Window > Android SDK Manager. Install the SDK Platform and Google GDK Sneak Peek for Android 4.0.3 (API 15). Everything else is optional.
