When I hover over something, quick documentation always says "fetching documentation". It takes a few seconds to show the documentation.
I read this question and found that this is because Android Studio is always trying to access docs online and not the offline copy.
This was the answer given.
In jdk.table.xml, find all the lines:
<root type="simple" url="http://developer.android.com/reference/">
and modify them to
<root type="simple" url="file://$USER_HOME$/Library/Android/sdk/docs/reference/">
However, when I checked, docs folder is missing from that location.
This is my sdk manager
This is my project structure
