I recommend ignoring the timestamp (and retry count) if the last non- retry response you've received was a "licensed" response. Yes it could theoretically be taken advantage of, but it can really reduce the number of false positives. I used to do this and the only false positives are when people reset/switch roms/whatever and use a new google account (so not really a false positive).
But in a recent update I accidentally did something to sometimes require the timestamp (I have my own LVL-copy that doesn't require Google Market that I use for direct purchases, and I made a change there). Then it seems at the end of last month a handful of LG Optimus phones changed the date incorrectly (???). Users on these devices were locked out but if they set the date to the correct date then the problem was resolved. (Naturally some users had the problem with other apps too, not just mine). Weird. It was only a handful of users that emailed me about it, but I was used to never getting actual false positives, due to ignoring the time stamp before, that it was quite surprising. I've still had a few other reports from users on other devices so I do plan on ignoring the timestamp again in my next update. The pirates don't really attack LVL at that level anyway, they look for where the allow/deny decisions are made and make their smali changes there. -Kevin On Jun 6, 6:19 am, Zsolt Vasvari <zvasv...@gmail.com> wrote: > Recently, I've been getting a lot messages from users about how I am > asking for the network to be enabled to verify the license using LVL. > I throw up this message whenever I cannot contact the licensing > server.
