问题描述

我总是遇到错误

未绑定到有效的相机

Not bound to a valid Camera

尝试实现imageCapture用例时.我要在camerax教程此处的Java中实现该功能.>.

when attempting to implement the imageCapture use case. I'm implementing the feature in Java following the camerax tutorial here.

预览用例已正确绑定，当我启动活动时，我可以访问相机，但是当我点击拍照"时，按钮，出现以下错误:

The preview use case binds correctly and I can access the camera when I launch the activity, but when I tap on the "take photo" button, I get the error below:

Photo capture failed: ${exception.message}

有人遇到类似的问题吗?有指针吗?

Anyone facing a similar issue? Any pointers?
