本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。我创建了这个项目，目标是 Android 版本 4.2 w/最低 SDK 2.3 并使用 4.3 构建。我对 AVD 进行了快速构建/运行测试，结果很好。然后，我按照迁移文档中的说明，将项目导出并为 Android Studio 生成了我的 Gradle 构建文件。当我尝试使用捆绑的 gradle 分发 (1.7) 导入 Android Studio 0.2.6 Build# AI-130.795381 时，我收到错误：“原因：未能找到目标 android-18”，并在 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 分发版“ 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”时出现问题。评估根项目“MyOtherLilAndroid”时出现问题。未找到 SDK 位置。使用 local.properties 文件中的 sdk.dir 或使用 ANDROID_HOME 环境变量定义位置。
在 idea.log 中使用以下堆栈跟踪：

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：找不到目标 android-18

我已经确认ANDROID_HOME是通过“~/.MacOSX/environment.plist”在我的Mac上设置的，并且在我的“~/.bash_profile”中设置的“~/.bashrc”中，最后我尝试设置sdk。项目的 local.properties 中的 dir 和 ndk.dir。使用捆绑的 gradle 我在 idea.log 中收到此错误：

是什么赋予了？有没有人成功地将项目迁移到 Android Studio？我在一个糟糕的时间尝试吗？我了解这些工具仍在大力开发中。请指教。
