java.lang.IllegalArgumentException：カメラ1の解像度が欠落している推奨解像度マップ

このエラーは、エミュレータでテストしていたCameraX.LensFacing.FRONTを使用しているときに発生します

コード：

PreviewConfig config = new PreviewConfig.Builder().setLensFacing(CameraX.LensFacing.FRONT).build();

    Preview preview = new Preview(config);

    TextureView textureView = findViewById(R.id.textureView);


    preview.setOnPreviewOutputUpdateListener(new Preview.OnPreviewOutputUpdateListener() {

                    ImageCaptureConfig imageCaptureConfig = new ImageCaptureConfig.Builder().build();

setLensFacing(CameraX.LensFacing.FRONT)をImageCaptureConfigに追加すると問題が解決するはずです

Nestosの回答に加えて、これを機能させるには、ImageCaptureConfigとPreviewConfigの両方にsetLensFacing(CameraX.LensFacing.FRONT)を追加する必要がありました。

setLensFacing(..)に渡したUseCaseの構成ごとにCameraX.bindToLifecycle((LifecycleOwner) this, imageCapture, preview)を呼び出す必要があります。
