我通常不想寻求SO
帮助来理解我的崩溃报告,但是(a)我可以从这里的专家那里学到很多关于阅读崩溃报告的知识,并且(b)我意识到我对导航不太了解像我希望的那样流动(这部分是我认为下面的崩溃报告特有的)。
所以我希望有人遇到过同样的问题,可以帮助我理解为什么我的应用程序崩溃了。
它有时只会崩溃,这让我无法理解为什么它是间歇性的。但是,当它崩溃时,它会在同一个地方崩溃,并具有相同的堆栈跟踪(如下所示)。
现在我看到它在 cmdPressed 中崩溃了(这个方法中有很多代码),但是我很难理解比这更深的东西。
通过阅读下面的崩溃报告,是否有人对我的应用程序崩溃的原因有任何建议???为什么它可能不一致?
