I'm trying to find out what JDK's version does my Android Studio use. I'm confused, because i have many versions in my /Program Files/Java catalog

enter image description here

Unfortunately the project structure doesn't have any JDK's version number. enter image description here

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.

    Out of curiousity, does anybody know why this - which does indeed appear to be the jdk - is in a folder named `jre`? My understanding is there a difference between the jre and jdk so I would have thought `jdk` would be more appropriate – fostandy Jul 24 '19 at 02:37

In the installation directory of Android Studio there is a "release" file where you will find the detailed java information.

Contents of C:\...\Android Studio\jre\release :

JAVA_VERSION="1.8.0_242"
OS_NAME="Windows"
OS_VERSION="5.2"
OS_ARCH="amd64"
SOURCE=""
