即使JRE 8安装在我的MAC OS Yosemite 10.10.3，而运行Android目前的工具在sdk -错误-“没有Java运行时目前，请求安装”会显示在终端-我如何解决这个问题?
我想安装Xamarin测试记录器-安装后 让我安装Android sdk SDK下载路径:Library/Developer/Xamarin/android-sdk 现在当我在工具文件夹中运行Android时，我得到了错误 没有Java运行时 我已经安装了JRE 8，并得到了验证 Java版本从他们的网站
有人能帮帮我吗!!

Pre-Requisite:
我已经在我的机器上使用brew安装了java11。
步骤1:酿造信息java11
输出:
/选择/自制/酒窖/openjdk@11
USER1-MacBook-Pro JavaVirtualMachines % brew info java11
openjdk@11: stable 11.0.12 (bottled) [keg-only]
Development kit for the Java programming language
https://openjdk.java.net/
/opt/homebrew/Cellar/openjdk@11/11.0.12 (670 files, 273.0MB)
Poured from bottle on 2021-10-09 at 13:07:04
From: https://github.com/Homebrew/homebrew-core/blob/HEAD/Formula/openjdk@11.rb
License: GPL-2.0-only
==> Dependencies
Build: autoconf ✔
==> Requirements
Build: Xcode ✘
==> Caveats
For the system Java wrappers to find this JDK, symlink it with
sudo ln -sfn /opt/homebrew/opt/openjdk@11/libexec/openjdk.jdk /Library/Java/JavaVirtualMachines/openjdk-11.jdk
openjdk@11 is keg-only, which means it was not symlinked into /opt/homebrew,
because this is an alternate version of another formula.
If you need to have openjdk@11 first in your PATH, run:
echo 'export PATH="/opt/homebrew/opt/openjdk@11/bin:$PATH"' >> ~/.zshrc
For compilers to find openjdk@11 you may need to set:
export CPPFLAGS="-I/opt/homebrew/opt/openjdk@11/include"
==> Analytics
install: 44,188 (30 days), 149,578 (90 days), 433,845 (365 days)
install-on-request: 19,074 (30 days), 63,262 (90 days), 187,286 (365 days)
build-error: 0 (30 days)
步骤2:将openJDK路径附加到现有路径。
echo 'export PATH="/opt/homebrew/opt/openjdk@11/bin:$PATH"' >> ~/.zshrc . bin:$PATH
步骤3:源现有shell或打开新终端以验证更改
来源 ~/.zshrc
步骤4:添加检查路径
而java
输出:/ opt /自制/ opt / openjdk@11 / bin / java
步骤5:
java——版本
openjdk 11.0.12 2021-07-20
OpenJDK Runtime Environment Homebrew (build 11.0.12+0)
OpenJDK 64-Bit Server VM Homebrew (build 11.0.12+0, mixed mode)

在2022年，只有安装了Android工作室:
检查Android studio中是否安装JDK。在Android Studio中，选择文件>项目结构。在SDK条目下，如果没有选择默认JDK，则从列表中选择，如果没有，则添加JDK，然后申请安装。 在Android studio中安装JDK后，只需直接从Android studio中添加JDK路径即可。在终端中运行下面的命令，就完成了。
echo 'export JAVA_HOME="/应用程序/Android Studio. home ="app/Contents/jre/Contents/Home"' >> ~/.zshrc . Home
现在，检查它是否工作。
❯Java -version Openjdk版本“11.0.11”2021-04-20 OpenJDK运行时环境(build 11.0.11+0-b60-7772763) OpenJDK 64位服务器虚拟机(build 11.0.11+0-b60-7772763，混合模式)
不需要从brew安装任何包或创建任何符号链接。Java已经嵌入到Android工作室中，我们可以直接在我们的系统中使用它。
运行这个
sudo ln -sfn /usr/local/opt/openjdk/libexec/openjdk.jdk /Library/Java/JavaVirtualMachines/openjdk.jdk
如果在尝试生成jks文件(密钥库)时遇到错误，那么尝试添加
/Applications/Android\ Studio.app/Contents/jre/Contents/Home/bin/keytool
在运行命令之前，像这样:
/Applications/Android\ Studio.app/Contents/jre/Contents/Home/bin/keytool -genkey -v -keystore ~/key.jks -keyalg RSA -keysize 2048 -validity 10000 -alias key
It's worth noting that with my current version of SQLDeveloper (21.2.1), there's another way to specify the JDK location. In my case, I was able to open up ~/.sqldeveloper/21.2.1/product.conf and set the JavaHome directive to the appropriate directory. I use jabba for JDK version management, and this path was something like ~/.jabba/jdk/amazon-corretto@1.8.292-10.1/Contents/Home. Needless to say, just setting that config value and restarting SQLDeveloper left me with a running copy again. This should work with any version of SQLDeveloper given the product.conf file exists inside your user's .sqldeveloper directory appropriate for the version you are using.
下面是在macos mojave 10.14.6版本上为我工作的
我安装了当前的jdk(https://www.oracle.com/java/technologies/javase-downloads.html)
然后分别做;
vim . bash_profile 在bash_profile中添加export JAVA_HOME=$(/usr/libexec/ JAVA_HOME 源. bash_profile
完成了。可以使用java -version命令查看版本。
