  /** =====================线程信息-结束============================================================================*/

二、日志分析

发生ANR的时候,系统会产生一份anr日志文件(手机的/data/anr 目录下,文件名称可能各厂商不一样,业内大多称呼为trace文件),内含如下几项重要信息。

2.1 CPU 负载

Reason: executing service com.xxx.xxx/.service.XxxService
Load: 16.06 / 14.89 / 12.93
CPU usage from 0ms to 1130ms ago (2023-04-12 19:43:26.700 to 2023-04-12 19:44:56.838):
  32% 30133/com.google.android.gms: 26% user + 5.8% kernel / faults: 156889 minor
  30% 1002/system_server: 20% user + 10% kernel / faults: 33892 minor
........省略N行.....
70% TOTAL: 38% user + 31% kernel + 0.2% iowait + 0.7% irq + 0.1% softirq

如上所示:

  • 第一行:发生ANR的原因
  • 第二行:1、5、15 分钟内正在使用和等待使用CPU 的活动进程的平均数
  • 第三行:表明负载信息抓取在ANR发生之后的0~1130ms。同时也指明了ANR的时间点:2023-04-12 19:44:56.838
  • 中间部分:各个进程占用的CPU的详细情况
  • 最后一行:各个进程合计占用的CPU信息。

名词解释:

  • user:用户态,kernel:内核态
  • faults:内存缺页,minor——轻微的,major——重度,需要从磁盘拿数据
  • iowait:IO使用(等待)占比
  • ​irq:硬中断,softirq:软中断

注意:

  • iowait占比很高,意味着有很大可能,是io耗时导致ANR,具体进一步查看有没有进程faults major比较多。

  • 单进程CPU的负载并不是以100%为上限,而是有几个核,就有百分之几百,如4核上限为400%。

2.2 内存信息

Total number of allocations 214578  进程创建到现在一共创建了多少对象
​
Total bytes allocated 32MB 进程创建到现在一共申请了多少内存
​
Total bytes freed 10MB   进程创建到现在一共释放了多少内存
​
Free memory 335KB    不扩展堆的情况下可用的内存
​
Free memory until GC 335KB  GC前的可用内存
​
Free memory until OOME 361MB  OOM之前的可用内存
​
Total memory 22MB 当前总内存(已用+可用)
​
Max memory 384MB  进程最多能申请的内存

从含义可以得出结论:**Free memory until OOME **的值很小的时候,已经处于内存紧张状态。应用可能是占用了过多内存。

ps:如果ANR时间点前后,日志里有打印onTrimMemory,也可以作为内存紧张的一个参考判断

2.3 堆栈信息

"Binder:1002_1" prio=5 tid=7 Native
  | group="main" sCount=1 dsCount=0 obj=0x12c01940 self=0x7a8d8c3400
  | sysTid=1020 nice=0 cgrp=default sched=0/0 handle=0x7a869be450
  | state=S schedstat=( 19616954905 44253949137 66794 ) utm=1314 stm=647 core=1 HZ=100
  | stack=0x7a868c4000-0x7a868c6000 stackSize=1005KB
  | held mutexes=

参数解读说明:

  • 第0行:
    • 线程名: Binder:1002_1(如有daemon则代表守护线程)
    • prio: 线程优先级
    • tid: 线程内部id
    • 线程状态: NATIVE
  • 第1行:
    • group: 线程所属的线程组
    • sCount: 线程挂起次数
    • dsCount: 用于调试的线程挂起次数
    • obj: 当前线程关联的java线程对象
    • self: 当前线程地址
  • 第2行:
    • sysTid:线程真正意义上的tid
    • nice: 调度优先级,nice值越小则优先级越高。
    • cgrp: 进程所属的进程调度组
    • sched: 调度策略
    • handle: 函数处理地址
  • 第3行:
    • state: 线程状态
    • schedstat: CPU调度时间统计, 见proc/[pid]/task/[tid]/schedstat
    • utm/stm: 用户态/内核态的CPU时间(单位是jiffies), 见proc/[pid]/task/[tid]/stat
    • core: 该线程的最后运行所在核
    • HZ: 时钟频率
  • 第4行:
    • stack:线程栈的地址区间
    • stackSize:栈的大小
  • 第5行:
  • mutex: 所持有mutex类型,有独占锁exclusive和共享锁shared两类

schedstat含义说明:

在这里插入图片描述
nice值越小则优先级越高。此处nice=-0,可见优先级相对较高;
schedstat括号中的3个数字依次是Running、Runable、Switch,紧接着的是utm和stm

  • Running时间:CPU运行的时间,单位ns
  • Runable时间:RQ队列的等待时间,单位ns
  • Switch次数:CPU调度切换次数
  • utm: 该线程在用户态所执行的时间,单位是jiffies,jiffies定义为sysconf(_SC_CLK_TCK),默认等于10ms
  • stm: 该线程在内核态所执行的时间,单位是jiffies,默认等于10ms
    可见,该线程Running = 19616954905 ns,也约等于19616ms。在CPU运行时间包括用户态(utm)和内核态(stm)。 utm + stm = (1314 + 647) ×10 ms = 19610ms。

结论:utm + stm = schedstat第一个参数值。

2.4 线程状态

堆栈信息中ANR发生的进程当前线程的状态,也是分析ANR问题的一个重要信息。

如上日志所示,本文截取了两个线程信息,一个是主线程main,它的状态是Blocked。另一个是Binder:1002_1,它的状态是Native。
教科书上说线程状态有5种:新建、就绪、执行、阻塞、死亡。而Java中的线程状态有6种,6种状态都定义在:java.lang.Thread.State中:
在这里插入图片描述
对应解释如下:
在这里插入图片描述
如上trace文件中的状态不止包含上述状态,还包含native等状态,多出来的状态哪来的?
其实trace文件中的状态还包含了CPP代码中定义的状态,下面是一张对应关系表:

下面我们继续看这些常见状态的案例。

三、trace文件中常见线程状态

根据示例可知当前主线程在等待获取<0x077aff1b>,继而搜索<0x077aff1b>发现当前trace.txt中无结果;退而求其次,继续搜索b.a.b.c.a.l,发现thread-35中在同时访问b.a.b.c.a.l中线程安全的方法b.a.b.c.a.l.j

示例为C中Runnable状态,表示当前线程可运行或正在运行。

上述示例中main-主线程状态为Runnable,为什么还会发生ANR呢?
这是因为虽然当前主线程状态为Runnable,但是可能有其它频繁调度的任务,导致cpu资源不足,无法及时执行到当前主线程,这个等待时间超过了ANR等待阈值,则会触发ANR,故需排查当前是否有频繁执行的任务。
