本文介绍了解析展锐平台Camera开发过程中出现的错误日志的方法。通过编写Java程序来解析特定格式的日志，将一串数字转换为具体的Camera操作，便于开发者快速定位问题。

出发点

在展锐平台开发Camera的时候有时候会遇到报错的情况，log如下：

在log中会出现HIST_ID0_-1_1_803_711_204_711_101_102_204_204_204_204_204_204_461_462_204_502_802_204_204_302_305_802_204_204_204_HEND 这样的一段包含很多数字的信息，这些数字是有含义的，代表报错之前执行的一些Action，有时候可以帮助我们分析错误的原因。

这些数字主要定义在
