# 安卓开发环境配置问题
|
|||
|
|
|
|||
|
|
## 一、gradle的问题
|
|||
|
|
|
|||
|
|
由于国内网络环境的问题，导致gradle经常没有办法正常下载，从而难以正常构建Android程序。
|
|||
|
|
|
|||
|
|
## 1.1 gradle下载失败的问题
|
|||
|
|
|
|||
|
|
Android Studio首次创建项目或其他操作时，会更新Gradle，由于一些原因会导致下载失败，就会提示ERROR：Gradle project sync failed。解决办法如下：
|
|||
|
|
1.根据报错提示的链接直接下载gradle-xxxxx.zip，可以通过浏览器在 https://services.gradle.org/distributions/ 下载对应的版本。
|
|||
|
|
|
|||
|
|
|
|||
|
|
|
|||
|
|
如上图所示，可以看到Android Studio正在下载gradle-8.0-bin.zip, 如果反复失败，可以通过上面的网址直接通过浏览器下载(如果不能访问可能需要使用科学上网)，在网页中，我们可以找到对应的下载链接。：
|
|||
|
|
|
|||
|
|
<img src="./Image/image-20231124132430205.png" alt="image-20231124132430205" style="zoom: 50%;" />
|
|||
|
|
|
|||
|
|
2.虽然AndroidStudio Gradle下载失败，但是会在你的C盘创建一个文件夹，如 C:\Users(你的用户名).gradle\wrapper\dists\gradle-6.5-bin\xxxxxxx(最后一级目录，每个人的文件名可能不一样)
|
|||
|
|
|
|||
|
|
<img src="/Image/image-20231124132703141.png" alt="image-20231124132703141" style="zoom:50%;" />
|
|||
|
|
|
|||
|
|
我们将步骤1中下载号的gradle-8.0-bin.zip复制到存在gradle-8.0-bin.zip.lck和gradle-8.0-bin.zip.part文件的文件夹中。
|
|||
|
|
|
|||
|
|
3.修改Android Studio的gradle-wrapper文件
|
|||
|
|
|
|||
|
|
<center>
|
|||
|
|
<img src="./Image/image-20231124133122986.png" alt="image-20231124133122986" style="zoom:50%;" />
|
|||
|
|
</center>
|
|||
|
|
|
|||
|
|
修改的方式如下，不同环境下路径存在不同，根据实际情况调整即可，重要的是要正确映射gradle的位置。
|
|||
|
|
|
|||
|
|
```shell
|
|||
|
|
# Fri Nov 24 11:56:39 CST 2023
|
|||
|
|
distributionBase=GRADLE_USER_HOME
|
|||
|
|
distributionPath=wrapper/dists
|
|||
|
|
# 这是修改后的distributionUrl,把原先的网络地址映射为本地地址，程序通过本地地址下载
|
|||
|
|
distributionUrl=file:///C:/Users/admin/.gradle/wrapper/dists/gradle-8.0-bin/ca5e32bp14vu59qr306oxotwh/gradle-8.0-bin.zip
|
|||
|
|
# 下面是原地址
|
|||
|
|
#distributionUrl=https\://services.gradle.org/distributions/gradle-8.0-bin.zip
|
|||
|
|
zipStoreBase=GRADLE_USER_HOME
|
|||
|
|
zipStorePath=wrapper/dists
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
4.最后，重启AndroidStudio或者点击Sync Now就可以了。
|
|||
|
|
|
|||
|
|
## 二、Maven仓库配置问题
|
|||
|
|
|
|||
|
|
目前最新版本的Android Studio的依赖配置和旧版本不太一样。一般来说，如果采用默认的仓库配置，下载速度过慢同时容易失败。
|
|||
|
|
|
|||
|
|
```shell
|
|||
|
|
# 旧版
|
|||
|
|
pluginManagement {
|
|||
|
|
repositories {
|
|||
|
|
//新增这 4 个
|
|||
|
|
maven { url 'https://maven.aliyun.com/repository/public/' }
|
|||
|
|
maven { url 'https://maven.aliyun.com/repository/google/' }
|
|||
|
|
maven { url 'https://maven.aliyun.com/repository/jcenter/' }
|
|||
|
|
maven { url 'https://maven.aliyun.com/repository/central/' }
|
|||
|
|
google()
|
|||
|
|
mavenCentral()
|
|||
|
|
gradlePluginPortal()
|
|||
|
|
}
|
|||
|
|
}
|
|||
|
|
dependencyResolutionManagement {
|
|||
|
|
repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
|
|||
|
|
repositories {
|
|||
|
|
//新增这 4 个
|
|||
|
|
maven { url 'https://maven.aliyun.com/repository/public/' }
|
|||
|
|
maven { url 'https://maven.aliyun.com/repository/google/' }
|
|||
|
|
maven { url 'https://maven.aliyun.com/repository/jcenter/' }
|
|||
|
|
maven { url 'https://maven.aliyun.com/repository/central/' }
|
|||
|
|
google()
|
|||
|
|
mavenCentral()
|
|||
|
|
}
|
|||
|
|
}
|
|||
|
|
|
|||
|
|
rootProject.name = "helloworld"
|
|||
|
|
include ':app'
|
|||
|
|
# 最新版 maven写法发生了改变 maven { url 'https://jitpack.io' } => maven { url = uri("https://jitpack.io") }
|
|||
|
|
pluginManagement {
|

|

```
