Build not work

Hello
I'm trying to build my first game on android. I tried https://unity3d.com/learn/tutorials...ilding-your-unity-game-android-device-testing. I installed Android Studio, Java JDK 9. I have problem with "Unable to list target platforms" and I found on google https://answers.unity.com/questions/1323731/unable-to-list-target-platforms-please-make-sure-t.html. It's solve this problem, but now I have another problem.

There are screens with logs:

 

JDK 9 still causes issues when building: https://forum.unity.com/threads/java-9-jdk-9-support-by-unity-android.499354/

Downgrading to JDK 8 should solve your problems.
