1、查看日志
由于安卓7版本的老旧，存在很多代码上缺陷
这次碰到在安卓7系统上使用自带的原生相机，从拍照切换到视频时出现崩溃，崩溃日志如下

2、分析日志、提取重点
其中造成崩溃的原因主要是如下内容，实际过程中日志更多，需要能提取有效日志进行分析
12-14 10:03:42.547 5483 5483 E AndroidRuntime: Caused by: android.content.res.Resources$NotFoundException: File res/drawable/ic_capture_video.xml from drawable resource ID #0x7f020050

3、寻找解决方法
其实很多原生系统引起的问题，并不是个例，属于历史遗留的潜在bug，不过毕竟是开源，所以很多开发者也会将问题和解决方案在github社区进行提交并解决，本次解决方法，就是在github上查询code发现已经有社区工作者发现了问题并提交了的代码。需要善于利用现有的工具和搜索方法帮助自己找到答案。
