Project Astoria was not and is not a plan by Microsoft to turn Windows phone into an Android launcher. As such, Astoria isn't intended to be public facing. Tools were leaked and people got really excited to see Android apps running on Windows devices. But the results may vary greatly and no matter how you figure, you are breaking the legal terms of use of Android APKs and Windows developer tools.
But, the silver lining is that Astoria may be the real deal, and Android app developers may have the drive to use Astoria to make their Android apps Windows compatible upon it's launch.
