Android Studio Not Showing Inline Error

I am using Android Studio(3.0) to make an Android App. But suddenly the Android Studio has stopped showing inline errors where as there are still errors which are shown while build

Solution 1:

Try running inspection manually with Inspect Code on the Analyze menu.

If that doesn't work then try doing this:

1. BACK UP your project.
2. Delete all .iml files and .idea folder.
3. Relaunch Android Studio and import your project
