Get rid of google market localization limitation to install an app I'd like to test last HBO GO android application to see how they implemented chromecast, but I'm in Canada and my devices are registered to play store Canada so I'm not able to install it. I have been looking for the single .apk on the web but I'm not sure if I could trust those I found. 
Does any body has an idea how I could get it or how to get rid of the localization limitations ?
Thanks
