简介Android音频子系统（十五）------Audio调试经验

你好！这里是风筝的博客，

欢迎和我一起交流。

两年前，我初来手机厂，还不会怎么分析log，当时刚从珠海芯片厂出来，遇到问题都是接上串口线，然后自己手动复现问题，然后对着串口查看下打出来的log分析异常。
但是来到手机厂之后一切的都变了，之前的方式已经不适用了。
原因有两个：

手机都是整机，不会专门接出串口线。
问题可能是概率的，不一定能复现，而且时间宝贵，自己一般不会去复现。

所以，过去的经验和分析模式已经用不上啦，时代变了。。。。。。

现在都是测试开启反馈工具箱，复现问题然后抓取log，开发就对着大量log（本质还是logcat和dmesg等）查找自己需要的信息。

所以现在出问题一般我都不会花自己时间去复现一遍，除非问题不好处理需要自己验证一些东西。

一开始我还天真的问，log信息里面那么多还杂，如何去分析我们自己audio模块。到现在，我也只能说，无它，唯手熟尔（熟练得让人心疼）…

一般出现问题的时候测试会通过截图的方式标记时间戳，开发通过搜索"takescreenshot"可以找到问题时间戳。
如果没有截图，也可以通过测试描述的场景自行找到问题时间点。

一开始我都会过滤出audio的log，避免其他模块的干扰，通过正则表达式可以筛选多个条件：

^(?=.*audio).*$

不过到后期我都懒得筛了，其他模块有时也有报错信息可以一并瞄一下…

针对我目前使用的MTK平台，不同的场景会打出不同的log，通过这些log可以快速找到问题点。

基本通过这些关键词，就可以初步定位解决一些audio的问题了，之后的复杂问题，只能说，道阻且长…
