vs-android 不合适 java 发现
vs-android not suitable java found
我在 Visual Studio 2013 中尝试使用 vs android 插件时遇到了很多问题。基本上我使用官方 github vs-[ 上的故障排除指南取得了一些进展=34=]网页。但现在我被困住了。在多次重新安装 JDK 和 Android SDK 之后，我得到了以下输出：
1>ANTBUILD : [dx] error : No suitable Java found. In order to properly use the Android Developer
这很奇怪，因为错误上方有一行：
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。但是因为某些原因，后来不想用了。
还有一个奇怪的地方就是输出有这部分：
1> [gettarget] Project Target: Android 2.2
1> [gettarget] API level: 8
虽然我在项目设置里的设置是：Android 5.0 (android-21)
我正在尝试构建从 vs-android page 下载的示例。那里的所有示例的问题都是一样的。

我猜你是 64 位 OS。
问题的根源来自 android 工具链用于获取 java 可执行文件的完整路径的批处理文件。它位于：android_sdk\tools\lib\find_java.bat
令人费解的是，批处理文件仅在“Program Files”文件夹下搜索 java 可执行文件，但不在“Program Files (x86) )" 文件夹下的 64 位 Windows.
如果您安装了 JDK 的 64 位版本，这很好，但如果您安装的是 32 位版本，则会失败，据我所知，需要 32 位版本才能制作 vs-android 工作正常，否则在从 Visual Studio 中调用 java 时会失败，因为 msbuild 任务存在一些问题（我认为与跟踪器有关）。
我发现的最简单的解决方案是在系统环境变量中定义 JAVA_HOME（我假设您已经拥有）并修改 [=31= 中的下一个代码（从第 44 行开始） ]find_java.bat 文件:
41: rem Check we have a valid Java.exe in the path. The return code will
42: rem be 0 if the command worked or 1 if the exec failed (program not found).
43: for /f "delims=" %%a in ('"%~dps0\find_java%arch_ext%.exe" -s') do set java_exe=%%a
44: if not defined java_exe goto :CheckFailed
其他人：
44: if defined java_exe goto :SearchJavaW
45:
46: rem Try to find java.exe by using JAVA_HOME if the previous step failed

49: if not defined java_exe goto :CheckFailed

关于 API 级别的消息与清单文件的 uses-sdk 设置有关，与项目的 vs-android 设置无关。有关详细信息，请参阅此 link：http://developer.android.com/guide/topics/manifest/uses-sdk-element.html
vs-android 中的一个在构建时使用，以便 select 在构建时正确 headers 和库，而另一个指示 Android OS 在部署 .apk 时。
希望对大家有所帮助！ :)
我遇到了这个问题。实际上在2020年并使用win10。我是 android 开发人员的新手，但却是一名经验丰富的程序员。经过大量安装错误和编译后，我推荐这个来解决。在简化的步骤中，首先我从我的计算机中删除了所有 java 版本，删除了所有可能的 PATH 和 SET。然后我安装了 jdk 1.8 (jdk-8u261-windows-x64.exe)。现在 find_java.bat 和 dx.bat 可以正常工作了。我的示例测试程序得到了完整的编译，没有错误。据我了解，Android 与最近的 jdk 版本不兼容。最新的兼容版本是 1.8.
找到了一个不需要降级到 JAVA8 的解决方案，因此，JRE 可以选择 运行 虚拟机用于“uiautomatorviewer”。
需要安装 Android Studio 并将以下位置添加到“路径”系统变量
C:\程序Files\Android\AndroidStudio\jre\bin
我有 jdk-11.0.6 并且“uiautomatorviewer”工作正常
