How to specify the JDK version in android studio?
提问by ThePartyTurtle
Android Studio is giving me a Gradle build error that looks like this:
Android Studio 给了我一个 Gradle 构建错误，如下所示：
Error:(3, 22) compileSdkVersion android-22 requires compiling with JDK 7
Now it gives me these clickable prompts:
现在它给了我这些可点击的提示：
Download JDK 7
Select a JDK from the File System
Open build.gradle File
And I have already downloaded and installed JDK 7. The problem is when I go to select it in the "File System" i can only find a directory named 1.6.0 JDK. Furthermore, the installation of JDK 7 skipped the bullet point where I would've selected the install directory, so I'm really not sure where it is. My java control panel says I have "Java 7 Update 79" so I'm pretty sure I'm close, I just need to tell android studio where it is. I also ran the java -versioncommand in the terminal and it says my version is "1.7.0_79".
而且我已经下载并安装了JDK 7。问题是当我在“文件系统”中选择它时，我只能找到一个名为1.6.0 JDK的目录。此外，JDK 7 的安装跳过了我选择安装目录的要点，所以我真的不确定它在哪里。我的 java 控制面板说我有“Java 7 Update 79”，所以我很确定我已经接近了，我只需要告诉 android studio 它在哪里。我还在java -version终端中运行了命令，它说我的版本是“1.7.0_79”。
Any help is appreciated!

You can use cmd+ ;for Mac or Ctrl+ Alt+ Shift+ Sfor Windows/Linux to pull up the Project Structure dialog. In there, you can set the JDK location as well as the Android SDK location.
您可以使用cmd+ ;for Mac 或Ctrl+ Alt+ Shift+ Sfor Windows/Linux 来拉出项目结构对话框。在那里，您可以设置 JDK 位置以及 Android SDK 位置。
To get your JDK location, run /usr/libexec/java_home -v 1.7in terminal. Send 1.7 for Java 7 or 1.8 for Java 8.
要获取您的 JDK 位置，请/usr/libexec/java_home -v 1.7在终端中运行。为 Java 7 发送 1.7 或为 Java 8 发送 1.8。
