本周我试图将一些项目迁移到Android Studio，并且我一直在碰到一些障碍。我最后的尝试涉及使用Eclipse ADT w /插件版本22.0.5v201307292155-757759创建简单的Hello World Android项目。我创建了这个项目，目标是Android 4.2版本，最低版本为SDK 2.3，并使用4.3构建。我对AVD进行了一次快速的构建/运行测试，效果很好。然后，我按照迁移文档中的说明导出项目并为Android Studio生成我的Gradle构建文件。当我尝试使用捆绑gradle分发（1.7）导入到Android Studio 0.2.6 Build＃AI-130.795381中时，我在idea.log中收到错误：“原因：未能找到目标android-18”与stacktrace：迁移到Android Studio

是怎么回事？有没有人成功地将项目迁移到Android Studio？我在不好的时间尝试？我知道这些工具仍处于重大的发展阶段。请指教。
我只是设法让一些工作。我使用Android Studio创建了一个“hello world”项目，并将其build.gradle复制到导出的Eclipse项目中，并使用捆绑的gradle distro 1.7。显然，Eclipse ADT导出的build.gradle和Android Studio生成并期望的build.gradle有很大不同。 – Cliff
我想我可能正在找出这一个。在强制我的项目进入AS后，由于项目未完全定义，我无法创建运行配置并遇到几个与路径相关的问题。出于某种原因，Eclipse ADT将该项目标记为使用构建工具版本18.0.1构建，导致上面的原始“未能找到目标18”错误。更新我的gradle版本以使用buildTools 17似乎满足了gradle同步和导入工具。更多关于这一点的。 – Cliff
