I had downloaded the API 23 and all its supporting tools and libraries but once I got an error due to API 23 and deleted all along the directory from the SDK and storage as well which I found from this following.
https://code.google.com/p/android/issues/detail?id=183122#makechanges
Now I want to reinstalling all these but its not displaying in SDK while the latest API (API 24) is displayed.
I am trying to reinstall for past 3-4 days but no progress.
EDIT
I got the option to re-install the api 23 but it shows the error as mentioned in the comment.
Any help will be appreciated
