迁移到Android Studio

这个周末，我试图将一些项目迁移到Android Studio，但遇到了一些障碍。我的最后一次尝试涉及使用带有插件版本22.0.5v201307292155-757759的Eclipse ADT创建一个简单的Hello World Android项目。我创建了该项目，目标是带有最低SDK 2.3的Android版本4.2，并使用4.3进行了构建。我在AVD上进行了快速的构建/运行测试，一切正常。然后，我按照迁移文档中的说明进行了项目导出并为Android Studio生成了我的Gradle构建文件。当我尝试使用捆绑的gradle发行版（1.7）导入Android Studio 0.2.6 Build＃AI-130.795381时，出现错误：“原因：未能找到目标android-18”，在idea.log中带有堆栈跟踪：

2013-08-31 16:04:31,465 [ 517146]   INFO - ject.ProjectImportErrorHandler - Failed to import Gradle project at '/Users/clifton/workspace/MyOtherLilAndroid'

当我尝试使用Gradle Wrapper（推荐）时，出现错误：无法使用Gradle发行版' http://services.gradle.org/distributions/gradle-1.6-bin.zip '执行构建。构建文件'/Users/clifton/workspace/MyOtherLilAndroid/build.gradle'行：9评估根项目'MyOtherLilAndroid'时发生问题。评估根项目“ MyOtherLilAndroid”时发生问题。找不到SDK位置。在local.properties文件中使用sdk.dir或使用ANDROID_HOME环境变量来定义位置。

在idea.log中具有以下堆栈跟踪：

我尝试下载Gradle 1.7并将其用于导入，但出现另一个错误：“原因：无法找到目标android-18

在idea.log中使用以下堆栈跟踪：

我已经确认在我的Mac上通过“〜/ .MacOSX / environment.plist”设置了ANDROID_HOME，并在我的“〜/ .bash_profile”来源的“〜/ .bashrc”中进行了设置，最后我尝试设置sdk。项目的local.prooperties中的dir和ndk.dir。使用捆绑的gradle，我在idea.log中收到此错误：

2013-08-31 16:14:15,943 [1101624]   INFO - dle.util.AndroidGradleSettings - Found Android SDK home at '/Users/clifton/android-sdk-macosx' (from local.properties file)

和此堆栈跟踪与gradle包装器：

是什么赋予了？是否有人成功将项目迁移到Android Studio？我在困难的时候尝试吗？我了解这些工具仍在大量开发中。请指教。
