Question

So I've tried everything I could find. It keeps showing the below. I tried replacing the tool folder (C:/Users/(My user name)/AppData/Local/Android/Sdk with a lower version. I tried replacing the entire sdk. I tried uninstalling then re-installing android studios. I really don't know what else to do. Kinda disappointing that I finally finished making an original minigame but can't build it. I've been struggling with this for the past 12 hours sigh. Thanks for your time!

根据LUIS Bot Sample，似乎......

Java 9删除了sun / misc / BASE64Encoder类。

解决方法是降级到Java 8.
