Android 许可服务？
我在我的一个应用程序中使用了从 http://developer 获得的许可证服务。 android.com/guide/publishing/licensing.html。它运行良好，当我将自己的 apk 放入手机时，它会显示“此应用程序未注册，请在 Android 市场购买此应用程序”，这很好。然而，今天我在某个论坛上看到了我的申请的一些副本。当我尝试时，许可证似乎不起作用。谁能告诉我我做错了什么。我真的非常感激。谢谢！
I am using a license service in one of my application which I got from http://developer.android.com/guide/publishing/licensing.html. It was working fine, when I put my own apk in my phone it will say "This app is not registered, please buy this app in Android Market" which is good. However, today I saw some copy of my application in some forum. When I tried it, it seems the license is not working. Can anyone tell me what I am doing wrong. I would really appreciate it a lot. Thanks!

检查你的 .apk 的 md5sum 和你发现的没有许可证检查的那个。如果它们不同，那么很可能有人破解了您的应用程序以删除许可证限制。
它并不完美，但是您是否阅读过混淆指南许可文档？
Check the md5sum of your .apk and the one you found with no license check. If they are different, then chances are, somebody cracked your app to remove the license restrictions.
It's not perfect, but have you read the obfuscation guide in the licensing docs?
