【问题描述】：
我的应用有问题。
我的活动不是原生活动，而是在 java 线程 run() 方法中调用原生代码（它将在所有活动生命周期内继续运行） 有时活动会静默崩溃（没有任何提示）并返回到我的应用程序的先前活动。 我对跟踪日志很感兴趣，但使用 ndk-trace 只能摆脱 libc.so 中的调用， 我在“堆栈”中看到对我的本机库的一些调用，有一种方法可以从堆栈中恢复我的源中发生崩溃的区域的一些指示？

【问题讨论】：
-
可以通过add2line工具查看crash功能。 stackoverflow.com/questions/5314036/…。比如两次空闲指针导致libc.so崩溃。
-
我检查了崩溃的 libc.so，但它只让我知道崩溃与某些内存分配/释放问题有关。
