How to fix the error :transformClassesWithDexForDebug com/android/dx/command/Main: Unsupported major.minor version 52.0?

Question

Android

Hello!
I am trying to run a test application under Ionic (Cordova).
I do according to the instructions ionicframework.com/getting-started
Stuck on the last step on the ionic build android command
I did everything that needed to be done before.
In particular, everything was done according to the instructions cordova.apache.org/docs/en/latest/guide/platforms/...
Now, with the ionic build android command,
I get the following errors:

C:\Users\khusamov\Documents\temp\myApp>ionic build android

Running command: "C:\Program Files\nodejs\node.exe"
C:\Users\khusamov\Documents\temp\myApp\hooks\after_prepare\010_add_platform_class.js

Java - Unsupported major.minor version 52.0 - What does it mean?
The "Unsupported major.minor version 52.0" error means that the application was compiled on Java 8 and will not run on versions below it.
You can install the latest version at
www.oracle.com/technetwork/java/javase/downloads/j...
not to be confused with JRE, you need JDK version 8
