我在google play开发者控制台上收到了很多关于该例外的报告，我无法理解为什么，因为我无法重现错误，它在我的所有设备上都能正常运行
这是我的自定义AlertDialog的源代码，崩溃的行是在方法结束时的show()调用上。有什么问题？
我在stackoverflow中检查了一些与此相关的问题，但我在宣布对话时实际上使用final，这是其他问题的解决方案，而且我还有异常报告。< / p>
非常感谢

自己有这个错误了一会儿。以下是我从Crashlytics获得的有用见解：
＆＃34;此崩溃通常是由您的应用尝试使用以前完成的活动作为上下文显示对话框引起的。例如，如果一个Activity触发AsyncTask尝试在完成时显示一个对话框，但是用户在任务完成之前从Activity导航回来，就会发生这种情况。＆＃34;

来自BadTokenException的文档：

这个令牌被赋予了它的attach方法上的活动，所以我猜你在某些情况下试图过快地显示对话框。尝试在post块中发布show方法
