Question

我花了一个多星期的时间，在我的代码和调试中添加日志，但无法重现任何崩溃以确定原因。所以我来到这里，希望有人曾经遇到过此次崩溃的经历，或者知道崩溃报告的含义。

我有多个崩溃报告，所有这些都是“/system/lib/libcutils.so中的本机崩溃”，但回溯有些相同。

我注意到大多数报告都有以下内容

(dvmCallJNIMethod(unsigned int const*, JValue*, Method const*, Thread*)+398)

还有一些

(dvmCallMethodA(Thread*, Method const*, Object*, bool, JValue*, jvalue const*)+354)

提前感谢！

Answer 1

Android使用Zygote启动应用程序，当Zygote抛出一个＆＃34;信号11＆＃34;这意味着一些进程访问禁止的内存区域。

我在您的报告中看到SkPixelRef，您在项目中使用OpenGL吗？如果你这样做，请记住OpenGL在独立于线程上工作，因此，初始化OpenGL在构造函数上使用的所有变量以避免这种问题。

我建议使用android_print / Log.Debug检查程序访问和失败的区域。

您可以使用 addr2line 转换地址，以便找到更多有用的信息，它是随Android-NDK提供的。关于您可以参考的addr2line用法：
