I would "recommend" using a full page iframe like this:
Upload a file to your server that contains this (in your example your server would be Yahoo!)
<!DOCTYPE html>
<html>
<head>
<style>
body, html, iframe {margin: 0; padding: 0; height: 100%; width: 100%; border: none}
</style>
</head>
<body>
<iframe src="https://google.com">
</body>
</html>
This should work alright for you and give the effect that the link is actually located on your own domain. Causing the APK download to look like it's on your machine.
The source domain can break free from the iFrame and therefore break your illusion. Many sites will do that, but it will still work properly for most of your needs.
