推荐答案

使用调试器。

在调试器中运行你的应用程序 - 这很简单，谷歌会找到你的指示 - 当它崩溃时，使用堆栈跟踪在代码中找到导致它崩溃的函数。

在函数顶部放置一个断点，再次放置你的应用程序。这次，当它进入功能并让你控制时它会停止。您现在可以单步执行代码，查看可变内容并了解正在发生的事情。



抱歉，我们不能为您这样做：我们不要无法访问您的代码或数据，如果我们这样做就不知道如何使用它！

Use the debugger.
Run your app in the debugger - it's pretty simple, google will find you instructions - and when it crashes, use the stack trace to locate the function in your code that made it crash.
Put a breakpoint at the top of the function, and your your app again. This time, it will stop when it enters the function and let you take control. You can now step through the code, looking at variable contents and working out what is going on.

Sorry, but we can't do that for you: we don't have access to your code or data, and wouldn't know how to use it if we did!
