我用的是deepar(https://developer.deepar.ai/)结合Flutter。我正在为android创建一个Flutter插件。我使用jetpack支持库camerax访问摄像头。该库提供了一个名为“ImageAnalysis”的用例(https://developer.android.com/training/camerax/analyze). 我试着把这个和迪帕结合起来。我希望通过摄像头与deepar一起显示的遮罩作为资产在应用程序包中。当我调用“switcheffect”时，应用程序崩溃。
Flutter插件
Flutter插件的体系结构遵循Flutter文档中的建议。

class ExamplePlugin : FlutterPlugin, ActivityAware {
    private var flutterPluginBinding: FlutterPluginBinding? = null
    private var activityPluginBinding: ActivityPluginBinding? = null
    // overrides are implemented but left out for simplicity
}
class PluginViewFactory(
    private val flutterPluginBinding: FlutterPlugin.FlutterPluginBinding, private val activityPluginBinding: ActivityPluginBinding
) : PlatformViewFactory(StandardMessageCodec.INSTANCE) {

    override fun create(context: Context?, id: Int, args: Any?): PlatformView {
        return PluginView(flutterPluginBinding, activityPluginBinding, context, id, args)
    }
}
class PluginView(
    flutterPluginBinding: FlutterPluginBinding,
    activityPluginBinding: ActivityPluginBinding,
    private val context: Context?,
    id: Int,
    args: Any?
) : PlatformView, MethodChannel.MethodCallHandler, PluginRegistry.RequestPermissionsResultListener,
    AREventListener {
    private val activity = activityPluginBinding.activity
    // I left out some code for simplicity

创建processcameraprovider

private fun startCamera() {
        val cameraProviderFuture = ProcessCameraProvider.getInstance(activity)
        cameraProviderFuture.addListener({
            cameraProvider = cameraProviderFuture.get()
            bindPreviewAndAnalysis(cameraProvider)
        }, ContextCompat.getMainExecutor(activity))
    }

绑定图像预览和图像分析用例

private fun bindPreviewAndAnalysis(cameraProvider: ProcessCameraProvider?) {
        // Preview
        val imagePreview = Preview.Builder()
            .build()
            .also {
                it.setSurfaceProvider(previewView.surfaceProvider)
            }

        // Analysis
        val cameraPreset = CameraResolutionPreset.P1280x720
        val width: Int
        val height: Int
        val orientation: Int = getScreenOrientation()
        if (orientation == ActivityInfo.SCREEN_ORIENTATION_REVERSE_LANDSCAPE || orientation == ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE) {
            width = cameraPreset.width
            height = cameraPreset.height
        } else {
            width = cameraPreset.height
            height = cameraPreset.width
        }
        arrayOfNulls<ByteBuffer>(NUMBER_OF_BUFFERS).also { buffers = it }
        for (i in 0 until NUMBER_OF_BUFFERS) {
            buffers[i] = ByteBuffer.allocateDirect(width * height * 3)
            buffers[i]?.order(ByteOrder.nativeOrder())
            buffers[i]?.position(0)
        }
        val imageAnalysis = ImageAnalysis.Builder().setTargetResolution(Size(width, height))
            .setBackpressureStrategy(ImageAnalysis.STRATEGY_KEEP_ONLY_LATEST).build()
        cameraExecutor?.let {
            imageAnalysis.setAnalyzer(
                it,
                { image ->
                    val byteData: ByteArray
                    val yBuffer: ByteBuffer = image.planes[0].buffer
                    val uBuffer: ByteBuffer = image.planes[1].buffer
                    val vBuffer: ByteBuffer = image.planes[2].buffer
                    val ySize: Int = yBuffer.remaining()
                    val uSize: Int = uBuffer.remaining()
                    val vSize: Int = vBuffer.remaining()
                    byteData = ByteArray(ySize + uSize + vSize)

                    //U and V are swapped
                    yBuffer.get(byteData, 0, ySize)
                    vBuffer.get(byteData, ySize, vSize)
                    uBuffer.get(byteData, ySize + vSize, uSize)
                    buffers[currentBuffer]?.put(byteData)
                    buffers[currentBuffer]?.position(0)
                    if (deepAR != null) {
                        deepAR?.receiveFrame(
                            buffers[currentBuffer],
                            image.width,
                            image.height,
                            image.imageInfo.rotationDegrees,
                            cameraSelector == CameraSelector.DEFAULT_FRONT_CAMERA,
                            DeepARImageFormat.YUV_420_888,
                            image.planes[1].pixelStride
                        )
                    }
                    currentBuffer = (currentBuffer + 1) % NUMBER_OF_BUFFERS
                    image.close()
                })
        }

        try {
            cameraProvider?.unbindAll()

            cameraSelector?.let {
                cameraProvider?.bindToLifecycle(activity as LifecycleOwner,
                    it, imagePreview, imageAnalysis)
            }
        } catch (e: Exception) {
            Log.e(TAG, "Use case binding failed", e)
        }
    }

使用deepar开关效果

private fun changeMask(mask: String) {
        try {
            val loader = FlutterInjector.instance().flutterLoader()
            val path = loader.getLookupKeyForAsset("assets/masks/$mask", "my_plugin_name")
            val maskFd: AssetFileDescriptor = activity.assets.openFd(path)
            deepAR?.switchEffect("masks", maskFd.createInputStream())
        } catch (exc: Exception) {
            Log.e(TAG, "Could not change mask", exc)
        }
    }

错误
调用“switcheffect”时，应用程序崩溃，出现以下错误：

附加说明
我在android仿真器（api级别30）和真正的android设备（pixel 2，android 11）上运行带有Flutter插件的Flutter应用程序时看到了这个错误。在调试模式和发布模式下运行Flutter应用程序时，我看到了这个错误。
欢迎提供任何帮助或建议。我刚开始从事flutter和android开发，所以我很有可能错过了一些重要的方面。
我还在deepar的github回购协议中发布了这个问题：https://github.com/deeparsdk/quickstart-android-java/issues/30
