Solved the problem by myself
Unity exception JDK not found
Hello Community :) today I tried to install unity (2020.1.4f1) with the Unity Hub.
I have selected the following modules:
Android Build Support (Android SDK & NDK Tools | OpenJDK) iOS Build Support Universal Windows Platform Build Support WebGL Build Support Windows Build Support (IL2CPP) Documentation The installation is successfully completed. But after I want to build an Android App (.apk) an error ouccurs. The error from unity descripes that the JDK module is missing.
I tried to install the JDK manually from oracle. Firstly I tried the newest JDK (jdk-8u261-windows-x64.exe) but this does not solve the problem. Secondly I tried an older JDK version (jdk-8u251-windows-x64.exe) but even this one does not solve the problem.
I had set the Java envrionment variable manually, but wihtout success.
I installed Android Studio, but without success.
I hope there is someone who can help me to solve this problem.
