Android设备监视器无法从Android Studio或终端启动 – UnsupportedClassVersionError

尝试从Mac上Android Studio的“工具”窗口启动Android设备监视器时出现以下错误。

在此处输入图像描述

当我打开日志文件时，我发现一个错误报告非常类似于与此类似的其他SO问题，尤其是这个问题。但是，使用sudo对我来说不起作用，虽然我得到类似的，但更短的错误数据：

Macs-MBP:tools macuser$ sudo ./monitor Password: Exception in thread "main" java.lang.UnsupportedClassVersionError: com/android/archquery/Main : Unsupported major.minor version 52.0 at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClassCond(ClassLoader.java:637) at java.lang.ClassLoader.defineClass(ClassLoader.java:621) at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:141) at java.net.URLClassLoader.defineClass(URLClassLoader.java:283) at java.net.URLClassLoader.access$000(URLClassLoader.java:58) at java.net.URLClassLoader$1.run(URLClassLoader.java:197) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:190) at java.lang.ClassLoader.loadClass(ClassLoader.java:306) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:247) ./monitor: line 41: /Users/macuser/Library/Android/sdk/tools/lib/monitor-/monitor.app/Contents/MacOS/monitor: No such file or directory ./monitor: line 41: exec: /Users/macuser/Library/Android/sdk/tools/lib/monitor-/monitor.app/Contents/MacOS/monitor: cannot execute: No such file or directory

背景故事：在笔记本电脑（El Capitan）上安装完整的新Android Studio后，我试图从IDE内部启动显示器。它抱怨说运行它需要Java 1.6。所以我安装了Java 6.然后当我尝试它时，我收到了上面的错误消息。

当我从Terminal java_home -V运行时，我得到以下内容

 Matching Java Virtual Machines (2): 1.6.0_65-b14-468, x86_64: "Java SE 6" /Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home 1.6.0_65-b14-468, i386: "Java SE 6" /Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home

我有同样的问题。基于日志文件，新版本的Android Studio需要Java 8“不支持的major.minor版本52.0”：不支持的major.minor版本52.0

我正在运行Linux，我目前安装了java8，所以我只需要使用：

 update-alternatives --config java

和

 update-alternatives --config javac

一切顺利。

它看起来好像你正在使用Mac，因此在Mac OS X上安装Java 8： Installed Java 7之后你可能需要或不需要执行以下操作，但终端仍在使用版本6

来自Unsupported major.minor版本52.0来源：维基百科的信息

J2SE 8 = 52
J2SE 7 = 51
J2SE 6.0 = 50
J2SE 5.0 = 49

JDK 1.1 = 45

令人困惑的是，我没有在共享位置安装Java 8（只有Android Studio中的捆绑版本）。通过自制软件安装它解决了我的问题。

 brew cask install java $ java -version java version "1.8.0_131" Java(TM) SE Runtime Environment (build 1.8.0_131-b11) Java HotSpot(TM) 64-Bit Server VM (build 25.131-b11, mixed mode)

Android Studio附带内置的Java 1.8，因此在开发Android应用程序时不会出现问题。但是当您启动Android Device Monitor时，它会使用在您的操作系统上运行的外部Java编译器。如果您之前已经预装了Java，那就不会有问题了。否则，您将面临同样的问题。

我试图将JAVA_HOME路径设置为在Android Studio中打包的java。它不起作用，可能是因为它是openjdk版本。

我的解决方案是从Oracle下载Java JDK 1.8并安装在我的计算机上。

如果您打开特定的错误消息，您将看到错误消息的前几行，如下所示。

 !SESSION 2017-12-20 08:17:02.597 ----------------------------------------------- eclipse.buildId=unknown java.version=9.0.1 java.vendor=Oracle Corporation

这就是我得到的。我在我的mac中安装了java 8和9，并将java 8作为默认值。根据错误消息，java虚拟设备需要java 9但它需要8.这就是发生问题的地方。所以我从我的机器上卸载了java 9然后它开始工作正常。

上述答案对我不起作用。我正在使用JAVA8，Android JAVA_HOME和/usr/bin/java 。对我来说更奇怪的是我的工具/目录也缺少uiautomationviewer工具。所以它让我想知道在安装过程中出了什么问题。

我最终做的是下载一个较旧的SDK工具版本（我按照这里的说明），并替换了整个sdk / tools文件夹。它工作….

在以下问题上观察到同样的问题：macOS Sierra 10.12.6 Android Studio 3.0.1

解决方法：从http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html 卸载 Java SE开发工具包8u 152和安装 Java SE开发工具包8u151

尝试右键单击sdk / tools / monitor.bat并单击“以管理员身份运行”
