如何在Android Studio中指定JDK版本？

Question

Android Studio is giving me a Gradle build error that looks like this:

Error:(3, 22) compileSdkVersion android-22 requires compiling with JDK 7

Now it gives me these clickable prompts:

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 -version command in the terminal and it says my version is "1.7.0_79".

Any help would be appreciated!

Answer 1

You can use cmd + ; for Mac or Ctrl + Alt + Shift + S for Windows/Linux to pull up the Project Structure dialog. In there, you can set the JDK location as well as the Android SDK location.

To get your JDK location, run /usr/libexec/java_home -v 11 in terminal. Send 1.7 for Java 7, 1.8 for Java 8, or 11 for Java 11.

对于新的 Android Studio 版本，请转到 C:\\Program Files\\Android\\Android Studio\\jre\\bin（或 Android Studio 安装文件的位置）并在此位置打开命令窗口并在命令提示符下键入以下命令：-

java -version

Answer 3

Android Studio Arctic Fox (2020.3.1)

In the Canary 14 of Android Studio Arctic Fox (2020.3.1), the JDK Location setting is moved to:

Settings > Build, Execution, Deployment > Build Tools > Gradle > Gradle JDK

Up to Android Studio 4.2

You can follow the answer from Ben Kane, the JDK Location setting is located in:

File > Project Structure > SDK Location

在 Mac 上，您可以使用终端转到/Applications/Android Studio.app/Contents/jre/jdk/Contents/Home （或安装 Android SDK 的任何位置）并在命令提示符中输入以下内容：

./java -version

Answer 7

The gradle sync uses the following JDK location:

In Android Studio, File -> Project Structure

Navigate to the SDK Location .

cd /Applications/Android\ Studio\ 4.1.0.app/Contents/jre/jdk/Contents/Home

➜  Home ./bin/java --version
