Android：在哪里可以找到这个LogCat错误的解决方案？

当我的应用程序统计时，我得到如下所示的错误（不是每次，只是偶尔）。是否有人可以告诉我在哪里可以搜索此错误的问题？我甚至不知道我的代码的哪一部分导致了nulpointerexception错误

应用程序显示崩溃，表示应用程序已停止，但仍在菜单上移动

可能是初始化处理程序的参数

是否还有其他由引起的？我将发布错误之前发生的一切@barwnikk代码是8000行，我不知道该发布哪部分。。你想看看splashscreen或者menuscreen吗？哇。这是一个文件？我不建议使用一个文件中的所有8000行。哈哈，不；），我上了大约25节课，但我不知道从哪里查找错误。我忘了在第一个问题中告诉大家：应用程序显示了一条崩溃消息，但它仍在继续，应用程序的其余部分工作正常。我在哪里可以调整该参数？
