`implementation 'com.android.support:appcompat-v7:26.1.0'` this line missing in **build.gradle(app)** — Ali, Mar 01 '18 at 11:59
@MohammadAli there are **implementation 'com.android.support:appcompat-v7:27.0.2'** should i add? — jeydi243, Mar 01 '18 at 12:06
I tried this but i see another problem with compilesdkversion which is 27 — jeydi243, Mar 01 '18 at 12:16
you wan to find some **DOC** for version detail after that u can very easy to understand how to work your gradle — Ali, Mar 01 '18 at 12:18

I'm getting the same problem since I import and add some material components. If you add any material components to your project I think that's the issue.

For the test that is the issue for material components or not, first invalidates caches and restarts, then when the android studio restarts, don't open the infected layout again, as it will break all of the android layout previews showing and then test something else that don't have any material components :)

But don't worry, it will fix in the next version.

Note: Thanks to Johnny Zen for the report here.
