You can offer an Android app on your site if the user/discoverer has permitted 'unknown sources' for app downloads in their settings, but to me the issue is trust. Not that the app store ensures you don't download malware, but people are not too trusting of site offering apps. Peer-reviewed apks could change that, and an app with malware would be found out before spreading too far. Maybe this is a way to at least bypass the stores. This does not address marketing and discovery.
