I am developing an Android application, and common users have to pay for it. But, I want to offer that application for free to my webpage users. I have a login in that webpage, so I can control what users access to the application. So the question is:
If I put the .apk into the private zone of my webpage, and users access it through the mobile, Do they download the application and can distribute it, or it just get installed on the phone?
And what if they access by PC?
Is there any way to avoid the download of the file, and just install it on the phone?
I fear installing without downloading is not possible, maybe you shoud think about a second version which needs a key (e.g. created by the device ID and a secret Prefix.
