我只是遵循了标准的Andr​​oid许可检查程序，最近我收到这些报告：

I just followed the standard Android licence checking procedure, and recently I get these reports:

java.lang.NullPointerException
at com.google.android.vending.licensing.LicenseValidator.verify(LicenseValidator.java:99)
at com.google.android.vending.licensing.LicenseChecker$ResultListener$2.run(LicenseChecker.java:228)
at android.os.Handler.handleCallback(Handler.java:605)
at android.os.Handler.dispatchMessage(Handler.java:92)
at android.os.Looper.loop(Looper.java:137)
at android.os.HandlerThread.run(HandlerThread.java:60)

这到底意味着什么？这正常吗？之前，我从来没有这样。 由于有问题的应用程序正变得越来越流行 - 可能这是一个迹象，有人试图破解应用程序以某种方式，以避免支付

What could this mean? Is this normal ? I never got this before. Since the app in question is becoming more popular - could this be an indication that someone tried to crack the app somehow to avoid paying?

非常感谢您的见解！

推荐答案

这异常，通常会遇到，当设备不具备谷歌Play应用安装或没有与默认的注册帐号。 当有老谷歌市场的应用程序的一个可能会得到这个例外。

This exception is usually encountered, when the device doesn't have the Google Play app installed or there is no account registered with the default. One might get this exception when the have the old Google Market application.
