问题 Does camerax provide api for lens facing changes callback? After switching the lens facing camera I want to be notified when it has finished changing and the camera is ready to use. Currently I'm using this dependencies of camerax implementation "androidx.camera:camera-lifecycle:1.0.0-beta01" implementation "androidx.camera:camera-view:1.0.0-alpha08" implementation "androidx.camera:camera-extensions:1.0.0-alpha08" 回答1: Sounds like you need a signal for when the camera starts emitting frames.

问题 I was trying to follow the "Getting Started with CameraX" codelab from google and I tried to do it in Java instead of Kotlin but when I ran it and tried to take a picture it gave me an error that says not bound to a valid camera. I can't find where the error is in the code.

Since I (or someone else) might need it in a future, I decided to post here as a question and post and answer to it for reference and scrutiny. Feel free to add better answer if you have one. The relevant code is: class ImagePickerActivity :
