Unity2020.1.4f1でビルドしたら、Google Play Consoleでエラーが出たので調べました。
管理者権限でcmdコマンドプロンプト起動して以下のコマンドを入れていく。

set java_home="C:\Program Files\Unity\Hub\Editor\2020.1.4f1\Editor\Data\PlaybackEngines\AndroidPlayer\OpenJDK"
set android_home="C:\Program Files\Unity\Hub\Editor\2020.1.4f1\Editor\Data\PlaybackEngines\AndroidPlayer"
cd "C:\Program Files\Unity\Hub\Editor\2020.1.4f1\Editor\Data\PlaybackEngines\AndroidPlayer\SDK\tools\bin"
sdkmanager.bat --update
