我用的版本Android Studio Dolphin | 2021.3.1 Patch 1

1.Gradle自身的版本下载慢

解决办法：修改gradle\wrapper\gradle-wrapper.properties中的distributionUrl

将https\://services.gradle.org/distributions为https\://mirrors.cloud.tencent.com/gradle

distributionUrl=https\://mirrors.cloud.tencent.com/gradle/gradle-7.4-bin.zip

2.Gradle下载依赖包慢

解决办法：修改settings.gradle

pluginManagement {
    repositories {
        //下面三个是我们自己加的
        maven { url 'https://maven.aliyun.com/repository/public/' }
        maven { url 'https://maven.aliyun.com/repository/gradle-plugin' }
        maven { url 'https://maven.aliyun.com/repository/central' }
        
        gradlePluginPortal()
        google()
        mavenCentral()
    }
}
dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositories {
        //下面两个是我们自己加的
        maven { url 'https://maven.aliyun.com/repository/public/' }
        maven { url 'https://maven.aliyun.com/repository/central' }
        
        google()
        mavenCentral()
    }
}
rootProject.name = "MyApplication2"
include ':app'
