As a requirement to run, PSPDFKit for React Native needs the latest stable version of Android Studio. Starting with version 4.2, Android Studio is now bundled with JDK 11.

Once the installation has completed, enter the following in your terminal app:

java -version

Then, verify that the JDK version has been correctly updated to 11:
