I have an app that use Google license protection service. I have tested successfully this app(that currently is on Google Play since a couple of weeks) and the license checking. Some days ago I have published another app with the same protection and another private static final byte[] SALT = new byte[] {....} And the license checking works fine also with this app. Today I have updated a single layout of the first app published. I have tested the app and with my surprise fails the license checking with a timeout problem (and my Internet connection works fine) 10-25 01:04:16.689: I

I've added licensing to my android application using LVL Library. Licensing works properly for normal users which buys it in Google Play (I think so - I don't have any feedback about problems). It worked also when I primarily tested it on second device with some test account. Currently I have problem that server always return NOT_LICENSED response code (1) on devices with test account whatever I set in "license test answer" in developer console. When I test on device with publisher account answer is correct (server returns what I set in "license test answer"). I've tested on signed release

I looked around online and saw some other posts complaining about how the Android licensing (LVL) library is slow, but no solutions. On an HTC Thunderbolt (brand new phone) it delays the startup time of a test app by 3-5+ seconds. Does anyone have any experience or ideas on calling this library asynchronously? Other solutions? I am just using the sample code provided basically. The really annoying part is that the whole app is frozen while this simple license check occurs, it's really bad. Thanks! Nitwit figured it out: the licenseCheck is asynchronous. So just fire it, then open the app with

I'd like be able to make a time-limited trial version of my application, but I'm not sure how I can reliably determine whether or not the user attempted to reinstall the application after the expiration date. I could likely store the initial installation date in a storage location that wouldn't get erased upon uninstall, but this doesn't seem like an ideal method. Does Google Play's Application Licensing support this feature, or is there another acceptable way to accomplish this? you786 To echo what was written in the comments: Have the device create a UUID, then send the UUID to a server like

I've been working on an Android App that has already been published to Google Play. For the next update (versionCode = 3) my client wants to include the LVL licensing scheme. The first thing I did was set up a static test response from the licensing server. I set the test response to LICENSED . After reading this in the documentation: This License Test Response will be sent to devices using [my email address] or the Test Accounts listed above for applications you have uploaded to Google Play. >Additionally, this account (but not the Test Accounts) will receive this response for >applications
