Android Studio - No JVM Installation found
提问by Syed Qarib
I'm having issues trying to boot-up Android Studio
我在尝试启动时遇到问题 Android Studio
When I try to launch it after installation I'm getting this error:
当我在安装后尝试启动它时，出现此错误：
No JVM Installation found. Please install a 64 bit JDK.
No JVM Installation found. Please install a 64 bit JDK.
My current system specification:
我目前的系统规格：
Operating System: Windows 8.0 64 bit version
JDK installed: JDK 1.8.0
操作系统：Windows 8.0 64 bit version
JDK安装：JDK 1.8.0
What I have tried:
我尝试过的：
I have tried what was reported in the error, and also in most of the solutions to set the JDK_HOMEvariable in environment variables to my JDK path (64 bit version) i.e. C:\Program Files\Java\jdk1.8.0_05
我已经尝试过错误中报告的内容，以及在大多数解决方案JDK_HOME中将环境变量中的变量设置为我的 JDK 路径（64 位版本）即C:\Program Files\Java\jdk1.8.0_05
*I also have tried rebooting system, just in case to test if the environment variable is not working without a restart
*I also have tried rebooting system, just in case to test if the environment variable is not working without a restart
I have seen these solutions and tried but none of them works, so don't mark it as a duplicate of any of these:
Android Studio installation on Windows 7 fails, no JDK found
With android studio no jvm found, JAVA_HOME has been set
Android Studio start fails on Windows 8 64bit
Android Studio does not launch after installation
我已经看过这些解决方案并尝试过，但它们都不起作用，所以不要将其标记为以下任何一个的重复：
Windows 7 上的 Android Studio 安装失败，未找到 JDK
使用 android studio 未找到 jvm，JAVA_HOME 已设置为
Android Studio 在 Windows 8 上启动失败 64 位
Android Studio 安装后无法启动
Here is the cmd output for java version:

I had the same problem. I tried setting all kind of paths but nothing worked. So I had to do some dirty fix. The only problem with this is that it opens a blank command line window.
我有同样的问题。我尝试设置各种路径，但没有任何效果。所以我不得不做一些肮脏的修复。唯一的问题是它会打开一个空白的命令行窗口。
I did the following to make it work.
我做了以下工作以使其工作。
- goto the AndroidStudio installation folder.
- goto
binfolder and openstudio.batin text editor - add
set JAVA_HOME=C:\Program Files\Java2\jdk1.8.0//your java path after the ECHO line. - goto
Start->All Programmes->Android Studio-> - right click on
Android Studioand click onproperties. - You will see the
Targetsomething like<installation path>android-studio\bin\studio64.exe - change it to
<installation path>android-studio\bin\studio.bat
- 转到 AndroidStudio 安装文件夹。
- 转到
bin文件夹并studio.bat在文本编辑器中打开 set JAVA_HOME=C:\Program Files\Java2\jdk1.8.0在 ECHO 行之后添加//您的 java 路径。- 转到
Start->All Programmes->Android Studio-> - 右键单击
Android Studio并单击properties。 - 你会看到
Target类似的东西<installation path>android-studio\bin\studio64.exe - 将其更改为
<installation path>android-studio\bin\studio.bat
Now you can access it by clicking it from the menu.
现在您可以通过从菜单中单击它来访问它。
Note :I tried it with 8, It works.
注意：我用 8 试过，它有效。

According to Oracle's installation notes, you should download/install JDK for the correct system. For your convenience, I have linked to it from the sentence above. If you still encounter problems, leave a comment. I have written some quick code that will tell you if your JVM is 64 or 32-bit, below. I'd suggest you run this class and leave a comment as to its output:
根据 Oracle 的安装说明，您应该为正确的系统下载/安装JDK。为了您的方便，我从上面的句子链接到它。如果您仍然遇到问题，请发表评论。我编写了一些快速代码，可以告诉您 JVM 是 64 位还是 32 位，如下所示。我建议你运行这个类并对其输出发表评论：
public class CheckMemoryMode {
public static void main(String[] args) {
System.err.println(System.getProperty("sun.arch.data.model"));
}
}

Uninstall Java 8 and clean your JDK_HOME and your JAVA_HOME enviromental paths. Then install 64bit JAVA 6 or 7 JDK of your preference.
卸载 Java 8 并清理 JDK_HOME 和 JAVA_HOME 环境路径。然后安装您喜欢的 64 位 JAVA 6 或 7 JDK。

I reproduced your issue on my Windows 8.1system :
我在Windows 8.1系统上重现了您的问题：
- Installed 64-bit JDK 1.8.0_11.
- Installed latest Android Studio Bundle.
- Went to Control Panel -> System -> Advanced system settings -> Environment Variables...
- Added JDK_HOMEpointing to my 64-bit JDK.
- Launched studio64.exe
- 安装了64 位 JDK 1.8.0_11。
- 安装了最新的 Android Studio Bundle。
- 进入控制面板 -> 系统 -> 高级系统设置 -> 环境变量...
- 添加了指向我的 64 位 JDK 的JDK_HOME。
- 推出studio64.exe
I got the same message you did. Thinking that it might be the environment variable, I did the following :
我收到了和你一样的消息。认为它可能是环境变量，我做了以下事情：
- Went to Control Panel -> System -> Advanced system settings -> Environment Variables...
- Changed the name of JDK_HOMEto JAVA_HOME.
- Launched studio64.exe
- 进入控制面板 -> 系统 -> 高级系统设置 -> 环境变量...
- 将JDK_HOME的名称更改为JAVA_HOME。
- 推出studio64.exe
It came up successfully !
它成功地出现了！

1-Right click on Android Studio and click on properties.
1-右键单击Android Studio，然后单击属性。
2-Replace studio64.exe in link by studio.exe.
2-用studio.exe替换链接中的studio64.exe。

In my case
就我而言
In Control Panel -> System -> Advanced system settings -> Environment Variablesthere is no JDK_HOMEOR JAVA_HOME
在Control Panel -> System -> Advanced system settings -> Environment Variables没有JDK_HOMEORJAVA_HOME
SO
所以
I addedan entry named: JDK_HOMEpointing to: C:\Program Files\Java\jdk1.8.0_25\(you have to point this to your JDK instalation path)
我添加了一个名为：JDK_HOME的条目， 指向：C:\Program Files\Java\jdk1.8.0_25\（您必须将其指向您的 JDK 安装路径）
And all seems to work fine now
现在似乎一切正常

Android Studio Works Perfectly fine with Java 1.8or Java 8. I was also having invalid JVM error. The reason was including ";" (semicolon) at the end of JAVA_HOMEpath value. The correct format for path value is:
Android Studio 与Java 1.8或完美配合Java 8。我也遇到了无效的 JVM 错误。原因是包括“;” （分号）在JAVA_HOME路径值的末尾。路径值的正确格式是：
C:\Program Files\Java\jdk1.8.0_xx (Replace xx with your current version)
C:\Program Files\Java\jdk1.8.0_xx（用你当前的版本替换xx）
Do not include ;(semicolon) at the end of JAVA_HOMEvalue
不要;在JAVA_HOME值的末尾包含（分号）

Here comes the solution.
解决方案来了。
Just start ANDROID STUDIO as administratorif you are using a non administrator windows profile!
如果您使用的是非管理员 Windows 配置文件，只需以管理员身份启动 ANDROID STUDIO ！
If your environment variables are correct that will do the trick. Enjoy!
如果你的环境变量是正确的，那就可以了。享受！

- For me this turns out to be Environment Variables not being inherited.
- Quick answer: reboot, than click on studio.bat, not studio.exe or studio64.exe
- 对我来说，这证明是环境变量没有被继承。
- 快速回答：重启，而不是点击 studio.bat，而不是 studio.exe 或 studio64.exe
================ Details =================
================ 详情================
"Right Click"-"Run as Administrator" works for me if: ** JDK_HOME or JAVA_HOME was set. (PATH didn't need to be changed for me) ** I run studio.bat, not studio.exe ** Note: By Default I am an administrator on a Microsoft Account (That Microsoft part may be affecting things), and I seldom reboot. I'm running Win8.1 64bit. I installed both JDKv1.8.0.0_25 32bit and 64 bit, and had JRE 32bit and 64 bit already installed (used by other software).
I found there was a difference in clicking on studio.bat, studio.exe, and running studio.bat from a command prompt. There is also a difference if I rebooted or not.
The difference: The System Environment Variables aren't all there depending on how I start the program.
To test:
In start menu drag a copy of "command prompt" to your desktop, then change properties so "Start In" is location of studio.bat
- copy studio.bat to studio_debug.bat (one we can mess with)
- drag a shortcut of studio_debug.bat to desktop for convenience.
- edit studio_debug.bat (right click --> edit)
- “右键”“以管理员身份运行”工作对我来说，如果** JDK_HOME或JAVA_HOME设置。（我不需要更改 PATH）** 我运行的是 studio.bat，而不是 studio.exe ** 注意：默认情况下，我是 Microsoft 帐户的管理员（Microsoft 部分可能会影响某些事情），并且我很少重启。我正在运行 Win8.1 64 位。我安装了 JDKv1.8.0.0_25 32 位和 64 位，并且已经安装了 JRE 32 位和 64 位（被其他软件使用）。
我发现在命令提示符下单击 studio.bat、studio.exe 和运行 studio.bat 有所不同。我是否重新启动也有区别。
区别在于：系统环境变量并非全部存在，这取决于我如何启动程序。
去测试：
在开始菜单中，将“命令提示符”的副本拖到桌面，然后更改属性，使“开始于”是 studio.bat 的位置
- 将 studio.bat 复制到 studio_debug.bat（我们可以搞砸的）
- 为方便起见，将 studio_debug.bat 的快捷方式拖到桌面。
- 编辑 studio_debug.bat（右键单击 --> 编辑）
== Change:
==变化：

- This may also help in debugging studio.bat:
- 这也可能有助于调试 studio.bat：

"%JAVA_EXE%" %ALL_JVM_ARGS% -cp "%CLASS_PATH%" %MAIN_CLASS_NAME% %*

echo Starting: "%JAVA_EXE%" %ALL_JVM_ARGS% -cp "%CLASS_PATH%" %MAIN_CLASS_NAME% %*
pause
"%JAVA_EXE%" %ALL_JVM_ARGS% -cp "%CLASS_PATH%" %MAIN_CLASS_NAME% %*
echo =================
Now when you run studio.bat from command prompt versus double clicking you may see difference in environment variables including JAVA_HOME and PATH. If you do you have same problem as me.
The problem seems to depend on:
- did you reboot since changing environment variables?
- didn't seem to matter if I was local or microsoft account
- may depend whether you are an administrator or other account type
- whether you start using studio.bat, studio.exe, or studio64.exe
.
FYI: The actual successful startup command executed by studio.bat on my system was as follows (includes studio64.exe):
"C:\Program Files\Java\jdk1.8.0_25\bin\java.exe" "-Xms128m" "-Xmx750m" "-XX:MaxPermSize=350m" "-XX:ReservedCodeCacheSize=96m" "-ea" "-Dsun.io.useCanonCaches=false" "-Djava.net.preferIPv4Stack=true" "-Djsse.enableSNIExtension=false" "-XX:+UseCodeCacheFlushing" "-XX:+UseConcMarkSweepGC" "-XX:SoftRefLRUPolicyMSPerMB=50" "-XX:+HeapDumpOnOutOfMemoryError" "-Didea.platform.prefix=AndroidStudio" "-Didea.paths.selector=AndroidStudioBeta" -Djb.vmOptionsFile="C:\android-studio\bin\studio64.exe.vmoptions" "-Xbootclasspath/a:C:\android-studio\bin\../lib/boot.jar" -Didea.paths.selector=AndroidStudioBeta -Didea.platform.prefix=AndroidStudio -cp "C:\android-studio\bin\..\lib\bootstrap.jar;C:\android-studio\bin\..\lib\extensions.jar;C:\android-studio\bin\..\lib\util.jar;C:\android-studio\bin\..\lib\jdom.jar;C:\android-studio\bin\..\lib\log4j.jar;C:\android-studio\bin\..\lib\trove4j.jar;C:\android-studio\bin\..\lib\jna.jar;C:\Program Files\Java\jdk1.8.0_25\lib\tools.jar" com.intellij.idea.Main
Hope that helps someone else.
现在，当您从命令提示符与双击运行 studio.bat 时，您可能会看到环境变量（包括 JAVA_HOME 和 PATH）的差异。如果你有和我一样的问题。
问题似乎取决于：
- 更改环境变量后是否重新启动？
- 如果我是本地帐户或微软帐户似乎并不重要
- 可能取决于您是管理员还是其他帐户类型
- 无论您是开始使用 studio.bat、studio.exe 还是 studio64.exe
.
仅供参考：studio.bat 在我的系统上执行的实际成功启动命令如下（包括 studio64.exe）：
"C:\Program Files\Java\jdk1.8.0_25\bin\java.exe" "-Xms128m" "-Xmx750m" "-XX:MaxPermSize=350m" "-XX:ReservedCodeCacheSize=96m" "-ea" "- Dsun.io.useCanonCaches=false" "-Djava.net.preferIPv4Stack=true" "-Djsse.enableSNIExtension=false" "-XX:+UseCodeCacheFlushing" "-XX:+UseConcMarkSweepGC" "-XX:SoftRefLRUPolicyMSPerMB=50" "- XX:+HeapDumpOnOutOfMemoryError" "-Didea.platform.prefix=AndroidStudio" "-Didea.paths.selector=AndroidStudioBeta" -Djb.vmOptionsFile="C:\android-studio\bin\studio64.exe.vmoptions" "-Xbootclasspath/ a:C:\android-studio\bin\../lib/boot.jar" -Didea.paths.selector=AndroidStudioBeta -Didea.platform.prefix=AndroidStudio -cp "C:\android-studio\bin\.. \lib\bootstrap.jar;C:\android-studio\bin\..\lib\extensions.jar;C:\android-studio\bin\..\lib\util.jar;C:\android-studio\bin\..\lib\ jdom.jar;C:\android-studio\bin\..\lib\log4j.jar;C:\android-studio\bin\..\lib\trove4j.jar;C:\android-studio\bin\. .\lib\jna.jar;C:\Program Files\Java\jdk1.8.0_25\lib\tools.jar" com.intellij.idea.Main
希望能帮助别人。
