你好！這里是風(fēng)箏的博客，

歡迎和我一起交流。

兩年前，我初來手機廠，還不會怎么分析log，當(dāng)時剛從珠海芯片廠出來，遇到問題都是接上串口線，然后自己手動復(fù)現(xiàn)問題，然后對著串口查看下打出來的log分析異常。
但是來到手機廠之后一切的都變了，之前的方式已經(jīng)不適用了。
原因有兩個：

• 手機都是整機，不會專門接出串口線。
• 問題可能是概率的，不一定能復(fù)現(xiàn)，而且時間寶貴，自己一般不會去復(fù)現(xiàn)。

所以，過去的經(jīng)驗和分析模式已經(jīng)用不上啦，時代變了。。。。。。

現(xiàn)在都是測試開啟反饋工具箱，復(fù)現(xiàn)問題然后抓取log，開發(fā)就對著大量log（本質(zhì)還是logcat和dmesg等）查找自己需要的信息。

所以現(xiàn)在出問題一般我都不會花自己時間去復(fù)現(xiàn)一遍，除非問題不好處理需要自己驗證一些東西。

一開始我還天真的問，log信息里面那么多還雜，如何去分析我們自己audio模塊。到現(xiàn)在，我也只能說，無它，唯手熟爾（熟練得讓人心疼）…

一般出現(xiàn)問題的時候測試會通過截圖的方式標記時間戳，開發(fā)通過搜索"takescreenshot"可以找到問題時間戳。
如果沒有截圖，也可以通過測試描述的場景自行找到問題時間點。

一開始我都會過濾出audio的log，避免其他模塊的干擾，通過正則表達式可以篩選多個條件：

^(?=.*audio).*$

不過到后期我都懶得篩了，其他模塊有時也有報錯信息可以一并瞄一下…

針對我目前使用的MTK平臺，不同的場景會打出不同的log，通過這些log可以快速找到問題點。

基本通過這些關(guān)鍵詞，就可以初步定位解決一些audio的問題了，之后的復(fù)雜問題，只能說，道阻且長…
