In android studio,cannot load 2 facets-unknown facet type:android and android-gradle和后续错误解决 二、Please select Android SDK

一、In android studio, cannot load 2 facets-unknown facet type : android and android-gradle

插件出问题了

File -> Settings - > Plugins -> Enable "Android Support" Plugin.

勾掉红色报错插件，再重新勾选就可以了

后续还有个问题

二、Please select Android SDK

File->Project Structure中将Build tools version，选中下选框，里边有内容，选中就可以了
