尝试启动 Android Studio 时出现 JDK 错误

Question

I have just switched from Windows7 to Windows8.1 and I'm having trouble making Android Studio work now.

I have installed Android Studio and the JDK. First I tried it out with the latest versions Android Studio v.0.8.14 and JDK 1.8 , but I could not get it to work. I then tried to use the versions I used on my previous Windows7, and installed Android Studio 0.8.2 and JDK 1.7.0_67 , but I still can't get it to work.

The error I'm getting is:

Failed to load JVM DLL C:\Program Files\Java\jdk1.7.0_67\jre.If you already have a 64-bit JDK installed, define JAVA_HOME variable in Computer > System Properties > System Settings > Environment Variables

I have set JAVA_HOME to my JDK path. I've tried to add \bin to that path, which didn't help. I've tried to add the JDK_HOME variable and set path to it, which didn't help either. I have also added "C:\Program Files\Java\jdk1.7.0_67\" to my PATH variable, which also didn't help. I tried editing studio.bat adding a string to point to my JDK folder, which also didn't work.

When I check my Java from console ( cmd ) I get the msg that it works find:

C:\Users\Igor>java -version java version "1.7.0_67" Java(TM) SE Runtime Environment (build 1.7.0_67-b01) Java HotSpot(TM) 64-Bit Server VM (build 24.65-b04, mixed mode)

Is Windows 8.1 the problem? Do I have to do something different on it?

Answer 1

I had exactly the similar problem:

failed to create JVM: error code -6 
JVM PATH: .............
If you already have a 64-bit JDK installed, define a JAVA_HOME variable in Computer > System Properties > System Settings> Environment Variables. 
Note: Do *not* choose a Java "JRE". You need to point to a full JDK, otherwise the IDE may fail to start. See http://tools.android.com/knownissues for more details.

Solution for me

I solved it with the help of Rahul Wadhai :

1) Go to C:\\users\\<your_user>.AndroidStudio2.2\\ and open studio.vmoptions

2) change -Xmx and XX:MaxPermSize to lower values(then you have currently) and try to run AS again. ( If it does, then you can increase the values back. )

3) If it doesnt help, then try to rename .AndroidStudioX.X and then open AS again.

4) If it doesnt help, then you can search the problem within this android folder (using TextCrawler) , maybe somewhere in config files, there needed to change something. And then you can import settings from old folder.

Answer 2

您必须在PATH变量的名为JAVA_HOME = "C:\\Program Files\\Java\\jdk1.7.0_67"的系统变量中创建一个新变量。

Answer 3

To get this working, I put my JDK path in the Path variable as the first item. For some reason, when it's the last item it does not work.

Answer 4

You need to mention the JDK folder path in the Environment variable:

JAVA_HOME=C:\Program Files\Java\jdk1.7.0_51

Don't use build number coming in cmd .

Answer 5

Follow these steps:

Control Panel>>System>>Advanced(tab)>>Environment Variables>>System Variables
New
 Variable name: _JAVA_OPTIONS
 Variable value: -Xmx512M

Answer 6

I tweaked the studio.vmoptions file when I followed a method in making it run faster and it stopped working showing the same JDK error.. I did most of the fix mentioned above and none worked for me. What worked for me though was deleting the studio.vmoptions file and everything was great again.

Answer 7

Go to your c:\\ users\\yourcomputername\\ for example .AndroidStudio1.5 You will see config and system folder in it then delete the .AndroidStudio1.5 using it as example . Go and relaunch the studio64

Answer 8

which worked for me after many frustrated attempts:

go to the folder C:\program files\Android\Android Studio\bin

rename the file 'studio.64' to 'studio.bat' and run this file.
