android-studio - 将 android studio 更新到版本 3.4 后 Gradle 失败

Question

我今天更新了 Android studio，我的 flutter 项目不再工作了。 Gradle 失败并显示以下消息:

---

我已经尝试在最新版本的 studio 中创建一个新的 flutter 项目并且构建正常。

问题似乎与我在我的项目中使用 google play 服务和 firebase 这一事实有关。我根据 IDE 的提示将谷歌服务更新到最新版本 (4.2.0) 并升级到 3.4.0

我在 android/app/build.gradle 中将 compiledSDKVersion 从 27 更新为 28

我已经将 android/gradle/gradle-wrapper.properties 中的 gradle 版本从 4.10.2 更新到 5.1.1，因为存在不兼容性，我被提示更新。

我已经完成重构>迁移到 AndroidX... 并包括:

android.useAndroidX=true
android.enableJetifier=true

在 gradle.properties 文件中

我已经尝试通过“文件>使缓存无效并重新启动...”来清除缓存

我试过 flutter clean 和 flutter doctor -v 没有显示任何问题:

C:\Projects\firebase_setup_app>flutter clean

Deleting 'C:\Projects\firebase_setup_app\.dart_tool\'.

我还更新了 android/build.gradle 依赖项:

   dependencies {
        classpath 'com.android.tools.build:gradle:3.4.0'
        //classpath 'com.android.tools.build:gradle:3.2.1'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath 'com.google.gms:google-services:4.2.0'
    }

android/app/build.gradle依赖如下:

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
    implementation 'com.google.firebase:firebase-core:16.0.1'
}

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

我的 pubspec.yaml 包含以下插件:

environment:
  sdk: ">=2.0.0-dev.68.0 <3.0.0"

dependencies:
  flutter:
    sdk: flutter

  # The following adds the Cupertino Icons font to your application.
  # Use with the CupertinoIcons class for iOS style icons.
  cupertino_icons: ^0.1.2
  google_sign_in: ^4.0.1+3
  firebase_auth: ^0.8.4+5
  firebase_core: ^0.3.4
  #firebase_core: any
  firebase_database: ^2.0.3

有任何建议请解决，不胜感激!

Answer 1

我认为您的问题出在 androidX[正如我在错误中看到的那样]，而且您使用的是 firebase_auth: ^0.8.4+5 .

1.使用最新版本的android studio

1. 在 android studio 中打开您的 flutter 项目，转到 Refactor，选择 Migrate to androidX。
2. 当系统提示在新选项卡中打开窗口时[在新的 android studio 窗口中打开]，这将在此窗口中打开您的 android 应用程序文件夹，再次选择迁移到 android X。该过程完成后，导航到底部并选择重构。再次为您的应用午餐
