我在尝试在 Visual Studio 2013 中使用 vs android 插件时遇到了很多问题。基本上，我使用官方 github vs-android 网页上的故障排除指南取得了一些进展。但现在我被困住了。在多次重新安装 JDK 和 Android SDK 之后，我得到了这个输出：
1>ANTBUILD : [dx] error : No suitable Java found. In order to properly use the Android Developer
好吧，这很奇怪，因为错误上方有这一行：
1> Envvar: JAVA_HOME is set to 'c:/Program Files (x86)/Java/jdk1.8.0_66'
所以看起来它实际上能够找到JDK。但是由于某种原因，以后不想用了。
另一个奇怪的是，输出中有这部分：
1> [gettarget] Project Target: Android 2.2
1> [gettarget] API level: 8
虽然我在项目设置中的设置是：Android 5.0 (android-21)
我正在尝试构建一个从vs-android 页面下载的示例。对于那里的所有示例，问题都是相同的。
整个输出是：
