Android Studio's Project Preview is Blank in a New Project

This is a known bug. Here are the many options to fix it:

  • Build > Clean Project
  • Build > Rebuild project
  • File > Invalidate Caches/Restart
  • If all else fails, go to your styles.xml located in res/values. Make sure you're using the parent="Theme.AppCompat.Light.NoActionBar" theme, instead of the default. (If you want a dark theme, do the obvious and change it to Theme.AppCompat.Dark.NoActionBar

Why this happens/Why this fixes it:

For some reason, Android Studio still uses the deprecated ActionBar by default and I don't think the layout editor supports it anymore. Thus it's crashing anonymously.

To use a Toolbar since the ActionBar is deprecated, follow this link:
