文件google-services.json丢失。没有它，Google Services插件将无法运行。 （对于firebase ml套件）

Question

我已经看到一些与此错误相关的类似问题。但是我无法解决问题。 我正在使用Firebase ml套件来识别图像中的文本。我已将google-services.json文件添加到应用程序目录中，但仍然遇到相同的错误。如果有人可以解决此问题，请告诉我。

我遇到以下错误：

File google-services.json is missing. The Google Services Plugin cannot function without it.

我对项目的build.gradle：

buildscript {
    repositories {
        google()
        jcenter()

    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.3.1'
        classpath 'com.google.gms:google-services:4.0.1'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        jcenter()

    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

我的应用程式build.gradle：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 27
    defaultConfig {
        applicationId "app.shakil.com.datafactor"
        minSdkVersion 19
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

（我认为）原始海报回答了这个问题： “是的，我找到了答案。我将json文件放错了位置。尝试将json文件放在正确的目录中。我只是将json文件从项目级别移到了应用程序级别。– Sakhawat Hossain 19年10月22日，9：30”。
