每次更新到1.8路径时，Android Studio JDK位置都会更改回1.7 [英] Android Studio JDK location changes back to 1.7 every time it is updated to 1.8 path

问题描述

我最近安装了jdk 1.8 u92，之后Android Studio表示api24版本需要它。但是，我现在遇到了这个问题。

我查看了其他一些解决方案并卸载了jdk 1.7，为JDK_HOME，JAVA_HOME和JAVA8_HOME添加了环境变量。问题仍然存在。

每当我尝试构建应用程序时，gradle同步失败，Android工作室要求我选择有效的JDK目录 。然后我转到项目结构=> JDK位置并将其更新到1.8文件夹。尝试再次构建会产生相同的错误，当我检查项目结构时，路径将自动重新设置为旧的JDK 1.7。

是否有针对此问题的修复？

解决方案

查看Android工作室设置目录中的几个文件后想出来。

如果您一直在升级Android Studio并从以前的安装中导入设置，可能会发生这种情况（全新安装也可能会发生这种情况）。

<解决方案：

1. 转到Android Studio配置文件夹所在的位置（通常位于$ HOME / .AndroidStudio2.1 / confg）。


2. 打开选项文件夹并删除文件 jdk.table.xml （保留备份以防万一）


3. 重启Android Studio

这解决了我的问题。新创建的jdk.table.xml将具有更新的java8值（最有可能从JDK_HOME环境变量中获取）。

I recently installed jdk 1.8 u92 after Android Studio said it is needed for api24 builds. However, I've run into this issue now.

I looked at some other solutions and uninstalled jdk 1.7, added environment variables for JDK_HOME, JAVA_HOME, and JAVA8_HOME. The problem still persists.

Every time I try to build the app, gradle sync fails and Android studio asks me to Choose a valid JDK directory. I then go to Project Structure => JDK Location and update it to the 1.8 folder. Trying to build again gives the same error and when I check the Project Structure, the path is set back to the old JDK 1.7 automatically.

Is there any fix for this issue?

解决方案

Figured it out after looking at a few files inside the Android studio settings directory.

If you've been upgrading your Android Studio and importing settings from previous installations, this might happen (it might also happen with a fresh installation).

Solution:

1. Go to wherever your Android Studio config folder is located (usually at $HOME/.AndroidStudio2.1/confg).
2. Open the Options folder and delete the file jdk.table.xml (keep a backup just in case)
3. Restart Android Studio

This fixed the issue for me. The newly created jdk.table.xml will have updated java8 values (which it most probably fetches from the JDK_HOME environment variable).
