android - flutter :迁移到 androidx

Question

使用android studio时，新建一个项目，添加如下条目:android/build.gradle(依赖项):

classpath 'com.google.gms:google-services:4.3.0'

和android/app/build.gradle(在底部)

apply plugin: 'com.google.gms.google-services'

gradle 构建失败并出现以下错误:

Finished with error: Gradle task assembleDebug failed with exit code 1

当我停止应用 google 服务所需的 google 服务插件时，此错误消失。Flutter 升级到最新版本。

完整的构建文件:

buildscript {
    repositories {
        google()
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.4.2'
        classpath 'com.google.gms:google-services:4.3.0'
    }
}

allprojects {
    repositories {
        google()
        jcenter()
    }
}

rootProject.buildDir = '../build'
subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
}
subprojects {
    project.evaluationDependsOn(':app')
}

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

和:

def localProperties = new Properties()
    def localPropertiesFile = rootProject.file('local.properties')
    if (localPropertiesFile.exists()) {
        localPropertiesFile.withReader('UTF-8') { reader ->
            localProperties.load(reader)
        }
    }

    def flutterRoot = localProperties.getProperty('flutter.sdk')
    if (flutterRoot == null) {
        throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
    }

    def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
    if (flutterVersionCode == null) {
        flutterVersionCode = '1'
    }

    def flutterVersionName = localProperties.getProperty('flutter.versionName')
    if (flutterVersionName == null) {
        flutterVersionName = '1.0'
    }

    apply plugin: 'com.android.application'
    apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"

    android {
        compileSdkVersion 28

        lintOptions {
            disable 'InvalidPackage'
        }

        defaultConfig {
            // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
            applicationId "de.sveri.shopli_new"
            minSdkVersion 16
            targetSdkVersion 28
            versionCode flutterVersionCode.toInteger()
            versionName flutterVersionName
            testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
        }

        buildTypes {
            release {
                // TODO: Add your own signing config for the release build.
                // Signing with the debug keys for now, so `flutter run --release` works.
                signingConfig signingConfigs.debug
            }
        }
    }

    flutter {
        source '../..'
    }

    dependencies {
        testImplementation 'junit:junit:4.12'
        androidTestImplementation 'androidx.test:runner:1.2.0'
        androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
    }

    apply plugin: 'com.google.gms.google-services'

完成setup of the google play services plugin你必须

• 添加 google-services.json 文件。

This file is generally placed in the app/ directory (at the root of the Android Studio app module). As of version 2.2.0 the plugin supports build type and product flavor specific JSON files. All of the following directory structures are valid:

// dogfood and release are build types.
app/
    google-services.json
    src/dogfood/google-services.json
    src/release/google-services.json
