I've been at this for a while now, and I've lost quite a bit of work time due to this error. I am just trying to install a fresh copy of Android Studio on my Mac running El Captian. Every single time it tries to install the SDK, I get this:
Ignoring unknown package filter 'platform-tools'
And it will not allow me to do anything. I have tried completely uninstalling android, installing fresh, restarting, and so on, but with absolutely no luck whatsoever. I've tried using a separate download with just the SDK tools, but same result. Was hoping someone could offer a solution that may have run across this before.
