eclipse - 迁移到安卓工作室

Question

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，最低 SDK 2.3，并用 4.3 构建。我在 AVD 上进行了快速构建/运行测试，一切顺利。然后我是否按照迁移文档中的说明导出了项目并为 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) 导入到 Android Studio 0.2.6 Build# AI-130.795381 时，出现错误:“原因:找不到目标 android-18”，在 idea.log 中有堆栈跟踪:

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

    at org.gradle.tooling.internal.consumer.async.DefaultAsyncConnection$2.run(DefaultAsyncConnection.java:71)

当我尝试使用 Gradle Wrapper(推荐)时出现错误:无法使用 Gradle 分发执行构建 'http://services.gradle.org/distributions/gradle-1.6-bin.zip '.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 中有以下堆栈跟踪:

我尝试下载 Gradle 1.7 并将其用于导入，但我收到另一个错误:“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，在我的“~/.bashrc”中，它来 self 的“~/.bash_profile”，最后我试过了在项目的 local.properties 中设置 sdk.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)

org.gradle.tooling.BuildException: Could not fetch model of type 'AndroidProject' using Gradle distribution 'http://services.gradle.org/distributions/gradle-1.6-bin.zip'.

以及这个带有 gradle 包装器的堆栈跟踪:

什么给了？有没有人设法成功地将项目迁移到 Android Studio？我尝试的时机不对吗？我知道这些工具仍在大力开发中。请指教。

Answer 1

我已经找到了上述问题的大部分答案。我的问题源于刚刚打开全新的 MAcbook Pro 并安装了所有工具(ADT/IntelliJ/Android Studio)。一个复杂的问题是我安装了两个不同的 Android SDK，一个与 ADT 捆绑在一起，另一个与 Android Studio 捆绑在一起。我最初在我的主驱动器 (~/android-sdk-macosx) 中创建了一个指向 ADT bundle SDK 的符号链接(symbolic link)，因为我的所有命令行工具(在我的其他项目中)都配置为在那里查看。我开始注意到在一个中创建的 AVD 在另一个中无法正常启动，这促使我替换上面的符号链接(symbolic link)并将其指向 AS SDK。

长话短说...我对 SDK 的混淆导致从 ADT 导出的项目仍然在其捆绑的 SDK 中看到构建工具 18 在 Android Studio 中不可导入。其他错误只是掩盖和混淆了潜在的问题。 (它们来自于强制导入项目的徒劳尝试。)
