启动android studio时出错

Question

I want to install and run Android Studio on my Windows 8 Pro 64-bit. I can install, but when I running the app, this error appears:

Failed to load JVM DLL C:\\Program Files\\Java\\jdk1.7.0_25\\jre. If you already have a 64-bit JDK installed, define a JAVA_HOMEvariable in Computer > System Properties > System Settings > Enviroment Variables.

I define a JAVA_HOME on system variable 3 times with this values:

First time:

C:\Program Files\Java\jdk1.7.0_25

Second time:

C:\Program Files\Java\jdk1.7.0_25 ; C:\Program Files\Java\jdk1.7.0_25\bin

And third time:

C:\Program Files\Java\jdk1.7.0_25 ; C:\Program Files\Java\jdk1.7.0_25\bin ; C:\Program Files\Java\jdk1.7.0_25\jre

But I have same problem in 3 states.

Answer 1

转到系统属性然后高级系统设置单击下面系统变量中的环境变量单击新建并输入变量名称JAVA_HOME和变量值java路径， （例如：C:\\Program Files\\Java\\jdk1.8.0）

Answer 2

运行 studio64.exe 而不是 studio.exe，有​​同样的问题，这对我有用

Answer 3

I am using Windows Pro 8 too, here is my JAVA_HOME setting:

JAVA_HOME=c:\\Program Files\\Java\\jdk1.7.0_15

What I can suggest is the following: If android-studio installed successfully and cannot launch it, go to your user profile folder :

cd %USERPROFILE%

delete ".AndroidStudioPreview"

open a new command line terminal:

set JAVA_HOME

make sure that the path returned is set to the proper java jdk directory. If this does not show anything this means that your environment variable is not available.

Then launch android studio out of the command line.

If the problem persists try to install a new jdk side by side and point to the new jdk with JAVA_HOME.

Answer 4

Make sure that the installation folder in

C:\\Program Files or C:\\Program Files(X86)

If its in Program Files directory set the environment variable as

C:\\Program Files\\jdk_name

else

C:\\Program Files(X86)\\jdk_name

Answer 5

Change your most recent JDK folder name to the version the application is looking for. Example:

Go to:

C:\\Program Files\\Java

and rename the folder with most recent JDK version from \\jdk1.7.0_XX to \\jdk1.7.0_25

Good Luck.

Answer 6

Define a environment variable JAVA_HOME pointing to the JDK location (without BIN folder), like this:

JAVA_HOME=C:\Program Files\Java\jdk1.8.0_101;

(Set it in system and local variable)

After that, add

%JAVA_HOME%\bin 

to PATH variable (both in system and local settings)

Be sure to point to JDK installation directory, not JRE directory .

Then restart your computer.

如果你安装了 android studio x64 你应该已经安装了 java sdk x64 如果没有你可以安装它然后再试一次
