UpdateAndRelease：GLConsumer未附加到OpenGL ES上下文

Question

当我尝试使用CameraX库打开相机时，我不断地遇到这个错误。相同的代码在其他设备上的运行比Pie少。但不是在馅饼上运行（摄像机未显示）

这是我的代码：我也在我的项目中使用生命数据，它会引起任何问题吗？

  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)
    val qrCodeAnalyzer = QRCodeAnalyzer { qrCodes ->
        qrCodes.forEach {
            Log.d("MainActivity", "QR Code detected: `${it.rawValue}.")`
            val intent = intent.putExtra("RESULT",it.rawValue)
            setResult(Activity.RESULT_OK,intent)
            finish()
        }
    }

    imageAnalysis.analyzer = qrCodeAnalyzer

    // We need to bind preview and imageAnalysis use cases
    CameraX.bindToLifecycle(this as LifecycleOwner , preview, imageAnalysis)

日志：看看我得到的日志

我也有类似的问题。我通过删除并重新添加SurfaceTexture来解决这个问题，如https://stackoverflow.com/A/56121351/11977949所建议的。

应将setOnPreviewOutputUpdateListener更改为：

preview.setOnPreviewOutputUpdateListener {
    val parent = viewFinder.parent as ViewGroup
    parent.removeView(viewFinder)
    viewFinder.surfaceTexture = it.surfaceTexture
    parent.addView(viewFinder, 0)
    updateTransform()
}
