本节内容我们聚焦到androidQ上，分析android中一个用于debug的功能，那就是 tombstone ，俗称“墓碑”。现实生活中墓碑一般是给死人准备的，而在android系统中“墓碑”则是给进程准备的。为何Android要设计出这样一个东西呢？因为android系统是运行在Linux Kernel内核之上的，当内核出现异常，则内核异常机制会分辨出是什么原因，处理不了的直接panic。而对于运行在Linux Kernel内核之上的android系统，如果出现异常，一般会自动重启android层的，这就导致问题很难复现定位debug，则当android层出现异常，通常会将进程的上下文信息

本文用于总结开发过程中遇到的重要问题分析原因及其解决方案 1、libnativeloader.so" is not accessible for the namespace “classloader-namespace” 原因：安卓高版本中将会限制三方APP访问非NDK公开so库，即不能访问system/lib/lib64下面的私有so库。两种情况的解决方案：第一：若是系统system app，该问题的产生原因是app是通过install的，这样不可行，必须将该模块在编译产品后的system/app路径
