Question

我正在尝试使用Firebase ML套件扫描QR码，但无法在Android Pie（诺基亚6.1 Plus）上启动相机。但是，相同的代码在Android Oreo Redmi 6 A

上正常工作

这是我的礼物：

implementation "com.google.firebase:firebase-ml-vision:21.0.0"
implementation "androidx.camera:camera-core:1.0.0-alpha05"
implementation "androidx.camera:camera-camera2:1.0.0-alpha05"

我已在清单中赋予了相机所有必需的权限和功能

这是我使用Camera X代码的方式：

      val previewConfig = PreviewConfig.Builder()
                .setLensFacing(CameraX.LensFacing.BACK)
                .build()

      val preview = Preview(previewConfig)


 preview.setOnPreviewOutputUpdateListener { previewOutput ->
                    textureView.surfaceTexture = previewOutput.surfaceTexture
                }


val imageAnalysisConfig = ImageAnalysisConfig.Builder()
                    .build()
                val imageAnalysis = ImageAnalysis(imageAnalysisConfig)

LogCat：

带相机X的Firebase mlKit条形码扫描仪mlKit在android Pie上不起作用
