Please follow the following instructions before filing a bug:

  1. Github issues under this project are only for sample-related issues. If you have modified the sample code in any way, then this is probably not the appropriate place to report a bug.
  2. If you are trying to report a bug related to the CameraX library then you can do so at the Android Issue Tracker: https://issuetracker.google.com/components/618491.
  3. Include the specific sample where you found the issue, in addition to device model and specific Android build number -- which can be found under Settings > About phone.
  4. Include error logs from logcat, if there are any.
  5. If you can, also attach a bug report-- but please keep in mind that personal information can sometimes be found in those, so double check before attaching.

我这边最近调查了一下，发现安卓Camera2中摄像头有3种：back, front, external。back和front就是前置、后置摄像头，external则是外部摄像头。有的安卓系统把连接的USB摄像头识别为前置、后置，摄像头ID都是数字，而有的安卓系统把USB摄像头识别为External，摄像头ID就是linux中的设备名称，比如/dev/video0。这貌似就跟具体安卓系统编译的时候的一些底层驱动设置有关，具体我也还没有深入了解。

CameraX目前只能识别前置和后置摄像头，因此安卓系统中如果将USB摄像头分类在前置或后置，就可以用CameraX打开

@mrliuzhao Thanks for sharing information. I have posted another issue here that discuss this topic too, you can have a look. So the question turns to how to set USB camera as front or back when compiling AOSP ? BTW, i wonder if android official team whether have plan to support USB camera in the future ? If yes, when is it, Thank you ! @owahltinez

@mrliuzhao @wow @bjain409 It's up to vendors because they customize the camera HAL. Does anyone know the list of Android phones which support USB Cameras?
