Encountered error while building game for Android

It also said 'In order to build for an Android target version newer than API16, you need to upgrade your Android SDK'

I've update SDK from Stencyl, upgrade JDK to the newest (jre-8u60) and using Stencyl Build 8670

Any suggestion anyone? Thank you.

Here's  log:

I'm having the same problem.

Have you found a solution already?

Found the solution for Android, I just run a clean project then it can be builded without problem.

But then I cannot build for iOS instead 

this is what I experienced several times on more games. First time I completely lost the game I was working on, after this I started to do backup once or twice a day and if something like this happen I move one step backwards

I'm having the same problem.
