This is a Website recommended by the ChromeOS subreddit for downloading APK's directly from the PlayStore.

http://apps.evozi.com/apk-downloader/

Just search for the app in google search, go on the playstore page of it and copy the url. For your app it is:

http://apps.evozi.com/apk-downloader/?id=com.gotv.crackle.handset

If you are using Kodi, use the crackle plugin instead

It is so much smoother and easier to navigate than the actual app

Come on someone its not hard to email it to yourself from ES file explorer then post it here if you have it :)
