android - Flutter:gradle build failed with error "A problem occurred evaluating root project ' android' > 配置项目 ':app' 时出现问题。”

Question

我的 flutter 应用程序在模拟器上运行良好，通过 USB 连接时在我的 android 上运行良好，但在从 Play 商店更新时在打开之前崩溃。对所有尝试过更新的人都这样做。所以我想我会尝试重建为 apk 并从 firebase 发行版安装。
如果我作为 appbundle 或 apk 运行，flutter build 工作正常，但仅在 apk --split-per-abi 上失败。
我不确定这个错误是否与它崩溃的原因有关，或者它是否是一个新问题。
这是我在运行 flutter build -v apk --split-per-abi 时遇到的错误

我似乎一直遇到与此相关的其他问题，这些问题是由 gradle 版本或谷歌服务版本引起的。我尝试了几个不同的版本。目前使用 https://services.gradle.org/distributions/gradle-6.5-all.zip 和

classpath 'com.android.tools.build:gradle:4.1.0'
classpath 'com.google.gms:google-services:4.1.0'

我还检查了错误消息中的文件，第 646 行包含: abiVersionCode * 1000 + variant.versionCode我已经运行了 flutter clean ，这是我的 flutter doctor -v 输出:

Answer 1

在 上更改 gradle 的版本安卓/build.gradle 文件到 3.5.0。

buildscript {
repositories {
    google()
    jcenter()
}

dependencies {
    ...
    classpath 'com.android.tools.build:gradle:3.5.0' // Use this version
}
}

在 android/gradle/wrapper/gradle-wrapper.properties ，您的 distributionUrl 还应该具有以下 gradle 版本。

gradle-5.6.2-all.zip

这样您就不会遇到任何其他问题。
最后，运行这些命令

rm -rf android/.gradle
rm -rf $HOME/.gradle # This is for Mac users
flutter build apk --target-platform android-arm,android-arm64,android-x64 --split-per-abi

它应该像一个魅力!稍后在事情变得不太成熟和稳定时更新 Gradle。
