How to specify the JDK version in Android Studio?

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.

How to find out the embedded JDK version of Android Studio?

The embedded JDK is included in the Android Studio install. If you open the folder where you installed Android Studio, you'll see a jre folder in it:

Inside the folder there is a file called THIRD_PARTY_README in which the second sentence says:

%% This notice is provided with respect to ASM Bytecode Manipulation 
Framework v5.0.3, which may be included with JRE 8, and JDK 8, and 
OpenJDK 8.

I'm using Android Studio 3.0, in which the embedded JDK version is 8. To find the version in any later version though, go to [SDK_INSTALL_ROOT]/jre/ and find THIRD_PARTY_README

---

THIRD_PARTY_README is in my system defined as a file and not a txt file. You can open it in Notepad, Notepad++ or any other text editor. The content is plain text. You can also look for a file called release, which contains similar information about versions.

Up to Android Studio 4.2

To set the default for new projects, go to File > Other Settings > Default Project Structure > SDK Location and set the "JDK Location".

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

Older Versions

Go to File > Project Structure > [Platform Settings] > SDKs. You'll need to either update you current SDK configuration to use the new directory, or define a new one and then change your project's settings to use the new one. This will set it for the current project.

To set the default for new projects, go to File > Other Settings > Structure for New Projects > [Platform Settings] > SDKs and set the SDK to use when creating a new project.
