AndroidJavaException: java.lang.ClassNotFoundException. How to decide?

Question

Java

I use Easy Mobile Pro.
One error in two places and looping:
1. AndroidJavaException: java.lang.ClassNotFoundException:
com.google.android.gms.ads.initialization.OnInitializationCompleteListener
2. AndroidJavaException: java.lang.ClassNotFoundException:
com.sglib.easymobile.androidnative.AppUtil

What should happen: When the button is clicked, a banner/interstitial/compensated ad is displayed.

Initialization hangs on an Empty object, it has the same display functions that use buttons.

Answer 1

Right-click (RMB) on My Computer - Properties - Advanced System Settings - Environment Variables - System Variables.
Here you add the JAVA_HOME variable
and value (the path to the JDK)
And also along this path C:\Users\Your user\.gradle\wrapper\dists
delete gradle 5.1.1-bin (you may have a different version, the essence is not changed)
AND everything works great.
