使用MLKIT条形码扫描仪的错误

Question

我正在使用Firebase的条形码扫描仪，但是我总是会遇到三个错误，我不知道它们是否可以影响我的应用程序

Failed to open file '/data/data/com.example.veggystock/code_cache/.overlay/base.apk/assets/mlkit_barcode_models/barcode_ssd_mobilenet_v1_dmp25_quant.tflite': No such file or directory

我的代码以使用UPC处理图像是这样

        scanner.process(image)
            .addOnSuccessListener { barcodes ->
                for (barcode in barcodes) {
                    val rawValue = barcode.rawValue.toString()
                    Log.d("RAWVALUE ->>>", rawValue)

                    CoroutineScope(Dispatchers.IO).launch {
                        val apiCall = getRetrofit(urlBaseUpc).create(ApiService::class.java)
                            .foodDatabase("parser?app_id=$appIdDatabase&app_key=$appKeyDatabase&upc=$rawValue")
                        //&health=vegetarian
                        if (apiCall.isSuccessful) {
                            apiCallBody = apiCall.body()!!
                            if (apiCallBody.listHints.isNotEmpty()) {
                                apiCall2 =
                                    getRetrofit(urlBaseNutrition).create(ApiService::class.java)
                                        .foodAnalysis("nutrition-data?app_id=$appIdNutrition&app_key=$appKeyNutrition&ingr=${apiCallBody.listHints.first().food.id}")
                                //&nutrition-type=cooking
                                runOnUiThread {

                                        apiCall2Body = apiCall2.body()!!

                                        if (apiCall2Body.healthLabels.contains("VEGAN")) {
                                            alertBuilder(

                                                "${apiCallBody.listHints.first().food.label} is Vegan"
                                            )
                                        } else {

                                            )
                                        }
                                    } else {
                                        Log.e("PROBLEM ->>", "API CALL NOT SUCCESFUL")
                                    }
                                }
                            } else {

                            }
                        }
                    }
                }
            }
            .addOnFailureListener {
                Log.e("PROBLEM ->>>>>>", "BARCODE NOT RECOGNIZED")
            }

Answer 1

这些资产/mlkit_barcode_models/*。tflite tensorflow Lite模型缺少。
如果它仍然检测到条形码，则可能是由于Playser-Services-Mlkit-Barcode-Scanning。

---

a）用于将模型与您的应用程序捆绑（较大的软件包）：

implementation 'com.google.mlkit:barcode-scanning:17.0.2'

b）用于使用Google Play服务中的模型（下载点播）：

implementation 'com.google.android.gms:play-services-mlkit-barcode-scanning:18.0.0'

扫描条形码在Android上。
