当我运行我的测试套件时，我总是在其中一个测试类中得到"Native Crash"或"Program Crash"错误。这个类自己运行得很好。我该如何开始调试呢?到目前为止，我所有的研究都提出了用Android NDK编译的本地代码调试的解决方案。奇怪的是，我只为这个项目编写Java代码。
作为参考，下面是一个崩溃示例的内存转储:

经过进一步的研究，我发现了这些看似相关的问题:
基于Android-Java的应用程序的本机崩溃?
本机崩溃/dev/ashmem/dalvik-jit-code-cache
致命信号11 (SIGSEGV)是无效的内存引用或分段错误。
线索1:如果你看过去的I/DEBUG ( 35): backtrace:
您将找到崩溃的相关库以及与该库中代码行相关的地址。
如果您没有权限查看和修改该库。
那么您应该跟踪它在java中确切崩溃的位置。最有可能的是，它传递了一个它无法处理的值。
编辑如果你没有使用任何库，仍然有一些情况下，基本sdk/api仍然可能默认为这样，因为它试图处理一个不应该处理的值。
