Hey @alorma @Sloy I managed to get it compiled against Android 12. However, there are some tests that were failing in previous builds and they are ok running locally. It seems to be trying failing due to the material components. Would this be considered a blocker for this if these tests are not passing?
No view matching ((an instance of android.widget.TextView and view.getText() with or without transformation to match: is "Hi! I'm the second screen!" or (view.getParent() is assignable from class <class com.google.android.material.textfield.TextInputLayout> and (view is an instance of android.view.ViewGroup and has descendant matching an instance of android.widget.TextView and view.getText() with or without transformation to match: is "Hi! I'm the second screen!")))) was found

If they didn't work on previous versions, it won't be a blocker to this PR. Don't worry! 😆 But feel free to open an issue, now that you've seen which tests didn't pass. Just to know the homework we have to do 😃

About my feedback, it's just a comment. I love having as simpler as possible Activities, so any code we could remove, I love the idea. That's why I think we could leave the CameraActivity as it was if we can, to keep this PR minimal.

Hey @rocboronat I've reverted the camera activity changes and created an issue for the failing tests. #456
