Preview is unavailable until a successful build

Question

I tried fixing this for ages now, but I don't know what to do. How do I get it to display a preview? Here is a screenshot of the code:

Click on clean project and rebuild project. After you can see preview design. :) — Jigar Patel, Nov 07 '17 at 18:52

The attached screenshot shows your Project is not sync properly. Here are some of the possible steps:

Use Sync Project with Gradle Files for more Here is answer with more detail.
If you made huge changes to project or changed package names etc. use rebuild
In menu Build => Rebuild Project.
Preview may not show if an API is selected that is not properly installed. Check Answer here.

One of the above should fix the problem. If none of the above work try restarting IDE (Android Studio).

Rebuild does not work. Just `Sync Project with Gradle Files` does. — sud007, Apr 19 '19 at 05:16

Follow these steps-

If you have any incomplete statement(s) in your code (probably where you left it last time) then comment those lines to make them inactive.
Go to Build=>Rebuild to rebuild the project.
Uncomment those lines to make them active again and you are done!!

Close the android studio and reopen the project again. If not work replace all 'compile' with 'implementation' from build.gradle file. Because it is obsolete now and will be removed at the end of 2018. I solved this kind of problem like that.

I tried above answers. But, sometimes they work and sometimes not.

I tried -

File -> Invalidate Caches/ Restart -> Invalidate and restart

And it always works for me.
