Missing required files to package this platform

I am trying to develop for android so I followed this page to install the files needed but each time I try to package my project UE4 gives me this error:

Missing required files to package this platform

I have checked the environment variables and they seem correct to me and have had this error on two different computers; my personal home computer and the computer at my college.

Hello SappyAneurysm.

Can you please provide the log files from your packaging attempt? Also, please take a screenshot of your settings in the editor under Project Settings > Platform > Android SDK.

We haven’t heard from you in a while, SappyAneurysm. Are you still experiencing this issue? If so, can you provide the information I requested? In the meantime, I’ll be marking this issue as resolved for tracking purposes.
