Unity3d, IntelliJ IDEA don't see JDK. There is a solution?

Question

Java

Windows 10 x64 system.
When choosing an android platform in Build settings on unity, I run into errors:

UnityException: Unable to find suitable JDK installation. Please make sure you have a suitable JDK installation. Android development requires at least JDK 8 (1.8), having JRE only is not enough. The latest JDK can be obtained from the Oracle website:

IntelliJ IDEA refuses to see SDK.
JDK costs, does not help.

Answer 1

you or the path for the JDK was not registered in Path. register and restart the computer.
(how to write the path..look for Path JAVA JDK) there should be a bunch of instructions on google.
or you have JDK 32-bit. and recently they want 64 bits.
delete. download 64 and install.

(I have windows 7 x64) put the contents of the OpenJDK folder (which I dropped above) into the unity version OpenJDK folder. (It worked for me) (example path: C:/Program Files/Unity/Hub/Editor/(version here)/Editor/Data/PlaybackEngines/AndroidPlayer (there will be an OpenJDK folder, rather it will be empty))
You can also look at the folder location via Edit=>Preferences=>External Tools.
