Markdown 插件中明确说明了不支持Android Studio,引用原文:

  • Live HTML preview (except Android Studio, see issue and workaround).

原因是Android Studio 不支持 JCEF,但好在有地方可以设置,参考以下步骤:

  1. Find action (ctrl + shift + A / command + shift + A)
  2. Search for ChooseBoot Java Runtime for the IDE
  3. Select the latest version in the "New:" dropdown - e.g. 11.0.12+7-b1504.27 JetBrains Runtime with JCEF
  4. OK
  5. Restart
