问题
Everything with my android studio was working fine until I came across this weird thing that when I add Views inside a CardViewthe IDE is warning me telling that for example "TextView is not allowed here". I have done this a thousand times before and It was absolutely fine.
Here is a List of the things I have tried
1. Restarted the IDE.
2. Restarted the entire system.
3. Tried the Invalidate Caches/Restart thing.
4. Cleaned the peoject.
5. Verified the support library version and files
6. Banged my head against the wall.
Nothing worked, here are some additional details
IDE version 1.3.1, SDK tools is using API 22 fully updated
And one more thing is suggestions are not shown under the CardView in XML, i guess both these problems are related.
I have seen a similar question here, but unfortunately it didn't help me.... Please someone find a fix for this problem...

Well after spending a day searching around in the Intelli J IDEA docs, I was able to find a solution for this problem. It has to do with the corrupted project metadata and other project related data that is common across projects loaded into Android Studio, so naturally I just opened a backup of my project that I had backed up when the problem did not exist. And I solved it....
Hope this'll help you...
