AndroidANR实例分析-源码交易平台丞旭猿

什么是ANR?

以下四个条件都可以造成ANR发生:

  • InputDispatching Timeout:5秒内无法响应屏幕触摸事件或键盘输入事件
  • BroadcastQueue Timeout :在执行前台广播(BroadcastReceiver)的onReceive()函数时10秒没有处理完成,后台为60秒。
  • Service Timeout :前台服务20秒内,后台服务在200秒内没有执行完毕。
  • ContentProvider Timeout :ContentProvider的publish在10s内没进行完。https://www.jianshu.com/p/388166988cef

实例分析

我们测试过程中跑monkey测试的时候,发生了ANR,LOG非常多。但是分析原因的时候还是非常考验思路。需要三个文件

1.搜索ANR in这个关键字

然后这里可以看到ANR 的PID是5563回到traces.txt找一下这个com.android.music

干他大爷的,发现没有找到~~

不着急,

我们刚才看那个日志的时候比较早,traces.txt可能会后面的日志冲掉了原因是

Wrote stack traces to /data/anr/traces.txt

这个是每次发生anr的时候,想traces文件写入数据的日志我们找最后一次写入这个文件的日志位置

然后我们继续搜下

从这个图片看到了,这个1125不断的被杀死,因为是系统进程,自己又无耻的启动,反复如此,就出现了上面的日志。

然后继续回到traces.txt里面分析

看thread.txt里面查看1125这个进程的名字是android.phone.

1125  1125 radio    20   0   0% S 1024340K  87388K  fg m.android.phone com.android.phone
 1125  1127 radio    29   9   0% S 1024340K  87388K  fg Jit thread pool com.android.phone

然后在看thread.txt里面查看562这个进程的名字是system_server,如下图

562   562 system   18  -2   0% S 1851968K 408908K  fg system_server   system_server
  562   567 system   20   0   0% S 1851968K 408908K  fg Signal Catcher  system_server

  562   588 system   20   0   0% S 1851968K 408908K  fg Binder:562_1    system_server

然后再在traces.txt里面看

----- pid 562 at 2018-12-27 03:03:32 -----
Cmd line: system_server
Build fingerprint: Android/rk3288_pad/rk3288_pad:7.1.2/NHG47K/52:userdebug/test-keys

这是system_server出现问题的时候记录下来的日志,然后继续往下看

这是出现问题的栈指针和函数调用的情况,可以看到是at android.media.MediaPlayer._prepare(Native method)at android.media.MediaPlayer.prepare(MediaPlayer.java:1365)这里出现了问题,具体原因需要根据日志去分析了

总结梳理一下流程

1125 这个是com.android.phone 是android 拨打电话的进程

562 这个是android_server 系统进程

这两个在日志里面不断的相爱相杀了很多次,从traces.txt的原因上来看是MediaPlayer.prepare阻塞的原因,但是android_server正常没人惹他,他是不会发生这么多次崩溃的,所以最终导致的原因应该是com.android.phone调用了system_server的东西。

然后为什么com.android.phone会有问题呢?继续摸索了一下日志

1125 调用了modem相关的东西,也就是在monkey测试过程中拨打了电话和,但是因为我们是平板项目,硬件上根本是没有modem的,原声的系统是也是去掉了这个apk的,我们是为了做暗码组合键功能才调出来的。

实际分析如上,如果有不正确的,请留言指正,谢谢
