Android Studio-找不到 JVM 安装

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:

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.

I reproduced your issue on my Windows 8.1 system :

1. Installed 64-bit JDK 1.8.0_11.
2. Installed latest Android Studio Bundle.
3. Went to Control Panel -> System -> Advanced system settings -> Environment Variables...
4. Added JDK_HOME pointing to my 64-bit JDK.
5. Launched studio64.exe

I got the same message you did. Thinking that it might be the environment variable, I did the following :

1. Went to Control Panel -> System -> Advanced system settings -> Environment Variables...
2. Changed the name of JDK_HOME to JAVA_HOME.
3. Launched studio64.exe

It came up successfully !

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.

I did the following to make it work.

• goto the AndroidStudio installation folder.
• goto bin folder and open studio.bat in 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 Studio and click on properties.
• You will see the Target something like <installation path>android-studio\bin\studio64.exe
• change it to <installation path>android-studio\bin\studio.bat

Now you can access it by clicking it from the menu.

Note : I tried it with 8, It works.

I think Android does not support Java 8. Officially android need java 6 as mentioned at the below:

https://developer.android.com/sdk/installing/installing-adt.html

Here I'm providing you a good link, hope those will clear this question :

Is it possible to use Java 8 for Android development?

1-Right click on Android Studio and click on properties.

2-Replace studio64.exe in link by studio.exe.

In my case

In Control Panel -> System -> Advanced system settings -> Environment Variables there is no JDK_HOME OR JAVA_HOME

SO

I added an entry named: JDK_HOME pointing to: C:\Program Files\Java\jdk1.8.0_25\ (you have to point this to your JDK instalation path)

And all seems to work fine now

Android Studio Works Perfectly fine with Java 1.8 or Java 8. I was also having invalid JVM error. The reason was including ";" (semicolon) at the end of JAVA_HOME path value. The correct format for path value is:

C:\Program Files\Java\jdk1.8.0_xx (Replace xx with your current version)

Do not include ; (semicolon) at the end of JAVA_HOME value

Here comes the solution.

Just start ANDROID STUDIO as administrator if you are using a non administrator windows profile!

If your environment variables are correct that will do the trick. Enjoy!

• 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

================ Details =================

• "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)

== Change:

@echo off

== to

@echo on
echo Set===================
set
echo ======================
pause

• This may also help in debugging studio.bat:

== change:

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

== to

echo =================
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:

  1. did you reboot since changing environment variables?
  2. didn't seem to matter if I was local or microsoft account
  3. may depend whether you are an administrator or other account type
  4. 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.

For crying out loud this is so VERY EASY TO Fix!!

1. Go to : "Control Panel\All Control Panel Items\System" once there click on "Advanced system settings" on the left hand side

2. The window that pops shows a box that says says Environment Variables! Click it.

3. Click "add new" to add new variable.

4. Type JAVA_HOME in the first box and in the second box the address to, IE / in my case C:\Program Files\Java\jdk1.8.0_25 save it. exit everything. THATS IT!!

Enjoy Android Studio! Obviously for the above to work you have to install java first or how else can you use it or point to it on your pc and all that. The above instructions are amazingly mislead and complicated. For the record I am on widows 8.1, YES it works on latest windows and is ridiculously simple to fix.

-OSG

Make sure you set the path in the SYSTEM VARIABLES not in the USER VARIABLES also.....name the variable name as JAVA_HOME and the address as C:\Program Files\Java\jdk1.8.0_25\ be sure that you didn't place any semicolon.

Just make sure that the installed version of both, Android Studio and JDK, are of either 32-bit or 64-bit. If JDK is of 32-bit and Android Studio of 64-bit or vice-verse, then it won't work though you set up JAVA_HOME.

You must just install jdk1.8.0 and then right click on my computer icon and then select properties,then in left panel, select advanced system settings, then in dialog bog select Environment Variables, then in that's dialog box,in section user variables create new variable that's name must be JAVA_HOME and path is C:\Program Files\Java\jdk1.8.0(in my pc) then sytem variable section, select PATH variable and append it's end this path C:\Program Files\Java\jdk1.8.0\bin and then select ok for all dialog box and after this steps run Android studio. And for test, run cmd in windows and run this command java -version if returned a java version and ... it is installed correctly.

Note: I get answer in windows 8.1 64 bit.

This is tested on my Windows 7 64Bit machine.

Quite strange... I had the same issue - WHILE IntelliJ Idea (including the Android Plug-in) was working perfectly.

However, here is what I did to get Android Studio 1.0 working (no step missing -> maybe it will help programming beginners).

Just set up a new environment variable by...

1. pressing Windows-Key and typing env... you'll see "Edit the system environment variables". Click!
2. Now click "Environment Variables..."
3. Under System variables (NOT "User variables") add a new entry named JAVA_HOME and set the value to your Java folder (like C:\Program Files\Java\jdk1.8.0_25)
4. apply and you are good to go.

PS: I don't know why some people writing about nuclear science when they want to explain how to set the Java path..

My JAVA_HOME was pointing to c:/jre directly. So I changed it to C:/java/jre because it was confused to pick up which one to use, so I changed it to the specific one and it works for me. Note: It is better to have only one JRE install on your machine

1 .Download 64 bit version of JDK from here

2. As shown in next picture, go to Control Panel -> System and Security -> Advanced system settings -> Environment Variables -> New (System variables)

3. Then add variable name: JAVA_HOME and variable value: C:\Program Files\Java\jdk1.8.0_25

Please note that jdk1.8.0_25 may be vary depending on JDK version.

4. Click OK button on the rest of the windows left.

Ok, was having this issue as well and this is what fixed it for me. For the record I'm using Windows 8.1 and Java JDK 1.8.31, all 64-bit.

The problem is with the space between "Program" and "Files" in the path set in JAVA_HOME. I've had this problem before but didn't really realize until I was checking the instructions here for setting JAVA HOME, then it all made sense.

In a nutshell, change the JAVA_HOME path from:

C:\Program Files\Java\jdk1.8.0_31

to

C:\Progra~1\Java\jdk1.8.0_31

Make sure to set the correct JDK version number for your installation. Removing the space from the path fixed everything on my system.

As noted on the page linked above,

use C:\Progra~1\ for C:\Program Files\

and C:\Progra~2\ for C:\Program Files(x86)\

depending on where you have the JDK installed on your system.

Note: Just to be clear, before making this change my system correctly echoed the value of JAVA_HOME to be C:\Program Files\Java\jdk1.8.0_31 in the command window, leading me to believe all was well. However, attempting to run %JAVA_HOME%\bin\javac reported that the path could not be found. After removing the space from the JAVA_HOME path the same command runs perfectly.

The solution is given in the error itself, Goto My computer(Right click)-->properties-->Advanced system settings-->Environment variables-->Create new variable.

Give the following details to it:

Variable name : JAVA_HOME.

Variable value : (your path to java jdk installation folder).

To find the path for java installation, go to program files in your window installation drive (normally C drive). Find folder named JAVA, in that navigate to JDK folder.

Copy the link address from the top, and paste it in the Variable value .

Now Press Ok and once environment variable gets created restart the android studio.

Hope it helps.

My fix was to remove the double quotes that I had enclosed the JAVA_HOME path in.

Instead of declaring JAVA_HOME as "C\Program Files..."

I removed the " and declared JAVA_HOME as C\Program Files...

I am on Win 7, x64

I also faced the same issue. The solution which helped me was I downloaded and installed 64 bit JDK from this link and set the "java_home" variable to the new JDK installed path like C:\Program Files\Java\jdk1.7.0_45. Hope this helps.

if your "enviornment variables" set well, than try to update Start > All Programs > Android Studio > Android Studio

do right click, click Properties and set android studio sdk path

in

shortcut > Target

If you are using windows 7, make sure you install jdk-xxxx-windows-x64.exe. http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html I had previously installed 32 bit instead of 64 bit version hence it was installed in program files x(86) folder. But if you install 64 bit sdk setup, its installed in program files folder. Then set the JAVA_HOME='C:\Program Files\Java\jdk1.8.0_65' It should work fine.

My variables pointed to other system variables so JDK_HOME was

%programfiles%\Java\jdk1.8.0_45

and i had to explicitly change it to

C:\Program Files\Java\jdk1.8.0_45

Similar for JAVA_HOME

Control Panel -> System -> Advanced system settings -> Environment Variables

I changed JAVA_HOME to JAVA and again changed JAVA to JAVA_HOME.

and Its working fine.

Had the same problem after upgrading my machine from 7 to 10 had to reinstall the JDK all overgain and took me only a few seconds. Here are the steps I followed.

Go to this link http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

Agree to oracle contact agreement.Then pick your windows version in my case is 64 bit after that its ..Next..Next,,once compete you can relaunch your Android studio without any problem. Hope this helps

I solved the problem in my case by deleting file

C:\Users\username.AndroidStudioX\studio64.exe.vmoptions

( x denotes the version of your android studio so it can be different ) , because I created it before to customize VM options. It's that simple

Add the your installation path and java path to the default system path by separating the ;

Right click on My Computer-->Properties-->Advances System Setting-->Advanced -->Environment Variables-->Under System Variables category find the "Path"-->add the android installation path and java path by separating with ;...

Believe it works

If it does not work after setting paths in environment variables correctly,
Reinstall Android Studio and it worked for me.

Under my Android Studio\bin there are two folder

studio.exe and studio64.exe

I tried to run the first program and it gives me the mentioned error.

But when running studio64.exe it works.
