我们正在开发一个 Android 项目，我们的平台是基于 ARM 的。 我们发现dalvik中发生应用程序崩溃的概率非常低。 下面是崩溃日志消息。 我认为段错误是由内存损坏引起的，这是此问题的根本原因，但我不知道如何调试此问题。
非常感谢任何提示。
问候，

最佳答案
从日志中我可以看到您正在使用 Android 2.3 (Gingerbread)。实际上这个版本在垃圾收集过程中存在一个错误。这就是为什么我认为存在 android 原生库崩溃的原因。

解决方法 -(取自上面的链接): 解决方法是自动存储对象数组元素。在里面 Bionic C 库，bcopy 例程是单独实现的 memmove，并且非常偶然地以原子方式移动字大小的值。 此提交将 System.arraycopy 切换为使用 bcopy 而不是 内存移动。
关于java - Android 段错误，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/17209146/
