Android 版本更新后许可证检查器崩溃

以前的一切都很完美。。。但是 今天，我的许可证检查器出了点问题（一句话也没说），这让我的应用程序崩溃了。因此，我看到该库的包管理器上有一个可用的更新，并进行了更新（我也更新了Eclipse）。 我还更新了这些方法，使它们能够与新的更新一起工作。 它工作了几个小时。 在某个Eclipse打开/关闭周期后再次停止工作（它编译但崩溃）：

这是LicenseCheck.java：

启动时自动工作。

引发的错误是classnotfound异常，您确定应用程序中没有丢失任何库文件吗？它工作得很好，然后我关闭了Eclipse并停止工作。。。编译器也没有给出任何错误。
