I had a few apps on my Androit phone, which does not exist for Amazon Kindle Fire - but I want to give reluctantly. So I exported it from your phone with the ES File Explorer on the phone and then installed with this Easy Installer on the Kindle Fire. Worked great and the games are now running on the Kindle.
What I super like: I have exported APPS simply copied to the download folder and the installer has immediately found by itself.
