So I've been interested in putting a referral system into my app. The first problem I ran into is, well people can just buy you app, refund, then restore from the sd card and bam! no payment.
well, I was considering this code (minus the calls to a, that's my parse object (http://parse.com)) try{ PackageManager pm = getPackageManager(); String installationSource = pm.getInstallerPackageName(getPackageName()); if(installationSource==null) installationSource = "nosource"; a.put("installsource", installationSource); }catch(Exception ex) { a.put("installsource", "no source"); } does anyone have any experience with this. It'll be null if they installed it off the sdcard (or onto an emulator). I'm attempting to prevent fraud. I thought I'd just share this tidbit (code is java, but easily converted) -- Extreme Knowledge is not something for which he programs a computer but for which his computer is programming him. -Wozniak - if my programming advice has helped you, feel free to donate to : <https://www.paypal.com/cgi-bin/webscr?cmd=_s-xclick&hosted_button_id=KYUXV2PG88YQQ> <https://www.paypal.com/cgi-bin/webscr?cmd=_s-xclick&hosted_button_id=KYUXV2PG88YQQ> <https://www.paypal.com/cgi-bin/webscr?cmd=_s-xclick&hosted_button_id=KYUXV2PG88YQQ>
