tracking adnroid and iphone downloads

[opticalpigion]

on iphone you can download apps only from app store,
but how can i check that the app is installed on the device?
how do the cpa ad networks track downloads and installs?

hmm, probably the callback to the server has to be integrated into the app,
so the app developers have to create a special edition of their apps for CPI ad-networks?

u can send device id to ur server
look at this

by the looks of things its not possible but this may help:

either use force file transfer:
header("Content-Description: File Transfer"); (nice script here: :: Smart File Download :: Free PHP Scripts )
or a pre-download page that refreshes to download...
and then just log if user agent is android/iphone
