Sovled this atlast. This Question helped me. Android Studio ClassCastException When Attempting to Open A Layout XML File . I had a 11MB xml file in values. That was the problem. After deleting that, the problem was solved.

And if you want to use a large XML file add the below code in idea.properties and vmoptions in the bin folder of Android Studio.

**Add in idea.properties**
 #-------------------------------------------------------------    --------
# Maximum file size (kilobytes) IDE     should provide code assistance for.
# The larger file is the slower its.    editor works and higher overall system     memory requirements are
# if code assistance is enabled.     Remove this property or set to very.    large number if you need
# code assistance for any files     available regardless their size.
#---------------------------------------------------------------------
idea.max.intellisense.filesize=999999


**Add in vmoptions**


-Didea.max.intellisense.filesize=999999     # <--- new line
