的tools.jar似乎不是在Android的工作室类路径中的Windows 8 [英] tools.jar seems to be not in Android Studio classpath on Windows 8

问题描述

我安装了Android的工作室，但它给我的错误，我需要安装JDK，但已经安装了JDK。然后，我意识到它是要求安装JDK的64位版本。

I installed Android Studio but it was giving me error that I need to install JDK but JDK was already installed. Then I realized it is asking to install 64bit version of JDK.

无论如何，我刚刚下载最新的JDK在64位版本，并设置在环境下面的变量，但仍Android的工作室给错误：

Anyway I just downloaded latest JDK 64bit version and set the following in Environment Variable but still Android Studio is giving error:

错误

'tools.jar' seems to be not in Android Studio classpath.  
Please ensure JAVA_HOME points to JDK rather than JRE.

以下路径在我的Windows 8集。

Path in User Variables  
E:\Program Files\Java\jdk1.8.0_25\bin

JAVA_HOME in System Variables  
E:\Program Files\Java\jdk1.8.0_25

Path in System Variables  
E:\Program Files\Java\jdk1.8.0_25\bin

32位JDK安装在C盘，而64位的JDK安装在E盘上（如上图所示）。 32位JDK不被使用在任何用户或系统变量。

32bit JDK is installed on C drive while 64bit JDK is installed on E drive (as shown above). 32 bit JDK is not being used in any User or System Variables.

我也重新启动计算机。

我该如何解决这个问题？

How do I fix this issue?

推荐答案

我试着尽我所能，但它并没有帮助。于是我重新安装了Windows和Android的安装Studio和现在一切正常。

I tried everything I could but it didn't help. So I reinstalled Windows and installed Android Studio and now everything works.

和讽刺的是，没有JAVA_HOME和JDK_HOME定义变量，但它仍然有效。

And the irony is, there is no JAVA_HOME or JDK_HOME variable defined but it still works.
