Not specifically a NOT_LICENSED response, but I recently had two users
where the LVL check was consistently, repeatedly timing out.
My LVL code is basically stock, based on next-to-last LVL version.
Based on logcat traces (both users were kind enough to provide these),
my code was able to request Market license checks just fine, but there
was no answer of any kind within the standard 15 second timeout.
Both users recently received official 4.0.* firmware upgrades, and both
have other devices with the same Google account configured in Market.
Go figure.

I get this on my own app, also having LVL. Quite embarrassing to try
to demonstrate the app to a friend and then it occasionally says that
my copy is not licensed - I have purchased it (since it was published
using a different account.)

Hello,
I have an Android developer account and a couple of paid apps
published on the Market since a while now. I have decided to use
Android LVL for copy protection from the start on all of my apps, I
found it pretty straightforward to use so I told myself why not?
extra
security is better than no security, right?
However, after almost one year since my apps have been out in the
wild, I keep getting from time to time unsatisfied customers which
after purchasing one app constantly get NOT_LICENSED replies from
Android licensing servers. And I'm not talking only about occasional
NOT_LICENSED caused either by lack of network coverage etc. but about
clients which try for days and days(yes, there are clients like this,
and they are right, since they paid for their apps!) and still get
NOT_LICENSED.
Now, here goes my questions:
1) For Android dev and apps publishers out there: have you noticed
any
wave of false negatives complaints from your clients lately? The
above-
mentioned symptom occurs in my case since the beginning, but since 2
weeks now it happens at a much higher frequency.
2) For any Google representative who might see this: are there any
kind of License Validation statistics on the Android Licensing server
side? Like for instance validation attempts per application, with
timestamp and Android Market client version and client ID(not email
for security reasons but "something")? And with some extra message
giving a reason for NOT_LICENSED?(apart the obvious didn't buy
reason,
could there be others?)
I think this should be implemented at LVL level and not at app level
due to permissions requirement(an app implementing statistics would
definitely require network access which for some apps does not
justify). So, can we have access to these statistics? If not now,
maybe sometimes in the future?
