概述

Android Studio升级到3.2之后，运行旧项目的时候出现了各种情况，特此记录下。

一、打包选项多了，一般情况下选择APK即可

二、打包发布的时候报错：Caused by: java.net.SocketTimeoutException: Read timed out

错误信息

错误信息

解决方案：

方案一：【管用】

其实就是jcenter仓库被墙了，打开翻.墙软件后，只是尝试打了一下google看看能不能打开来判断有没有翻.墙成功，并没有确定AS翻.墙成功。所以需要实现Android Studio翻.墙。

当它的第三方库已经下载到本地，设置了offline模式后，不用再次访问jcenter就能编译成功。但是如果把本地第三方库的缓存删掉了，那么就需要重新从jcenter下载。

我是用的翻.墙软件是蓝灯。

1、打开lantern，浏览器已经可以翻.墙了，但是as还不行，需要设置“代理全部流量”。

2、打开As，File—>Settings—>Appearance & Behavior–>System Settings–>HTTP Proxy—>Manual proxy configuration 

选择HTTP，host name填127.0.0.1，Port number 填之前你lantern上的端口号。

可以点击“check connection” 测试一下是否FQ成功。比如访问https://jcenter.bintray.com

3、重新打包即可。

参考资料：解决Unknown host ‘d29vzk4ow07wi7.cloudfront.net’. You may need to adjust the proxy settings in Gradle.

方案二：【管用，不过不建议使用】

在项目build.gradler 的jcenter()前添加上mavenCentral();

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    
    repositories {
        google()
        mavenCentral()//解决打包发布的时候报错：Connect to d29vzk4ow07wi7.cloudfront.net:443
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.0'
        

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        mavenCentral()//解决打包发布的时候报错：Connect to d29vzk4ow07wi7.cloudfront.net:443
        jcenter()
    }
}

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

jcenter VS mavenCentral

jcenter()和mavenCentral()是Android Studio中Gradle插件使用的仓库。

Android Studio早期版本使用的是mavenCentral，从某个时候开始切换到jcenter了。

这是因为jcenter在性能和占存储大小方面比mavenCentral更优：

• jcenter是Android的gradle插件使用的新默认存储库。
• jcenter是Bintray中的Java存储库，它是世界上最大的Java和Android OSS库，包和组件的repo。
• jcenter通过CDN服务，使用的是https协议，安全性更高，而Android Studio 0.8版本mavenCentral使用的是http协议
• jcenter是mavenCentral的超集，包括许多额外的仓库
• jcenter性能方面比mavenCentral更优
• mavenCentral会自动下载很多与IDE相关的index，而这些用到的少，且不是必需

摘自《jcenter vs. mavenCentral》

所以对于这个方案：

一、不建议使用，因为目前推荐使用的是jcenter()；

二、jcenter是mavenCentral的超集，而jcenter()中含有的库，在mavenCentral()中未必含有；

其他方案

尝试的方案一【不管用】、打开翻.墙软件，重新打包发布，一般来讲应该就会正常了。（根据信息分析得知是要下载groovy-all.jar文件。）

尝试的方案二【不管用】、如果还是报同样的错误，就采用下面的方案

手动下载groovy-all.jar文件：下载地址（在日志里面找）：https://jcenter.bintray.com/org/codehaus/groovy/groovy-all/2.4.12/groovy-all-2.4.12.jar

然后将groovy-all-2.4.12.jar文件复制到C:\Users\Administrator\.gradle\wrapper\dists\gradle-4.6-all\bcst21l2brirad8k2ben1letg\gradle-4.6\lib中

这个路径如何确定呢？首先在文件管理器的地址栏中输入C:\Users\Administrator

然后确定当前项目用到的gradle版本号，比如我的项目用到的是gradle-4.6，那么就把groovy-all-2.4.12.jar文件放到gradle-4.6-all\bcst21l2brirad8k2ben1letg\gradle-4.6\lib中

参考资料：解决android – Gradle, Groovy-all-2.3.6.jar Not found

三、依赖第三方库，不能使用latest.release作为最新版本号，应该使用实际版本号

比如依赖腾讯的bugly，之前的写法是：

    //Bugly
    compile 'com.tencent.bugly:crashreport:latest.release' //其中latest.release指代最新Bugly SDK版本号，也可以指定明确的版本号，例如2.2.0

现在的写法是：

    //Bugly
    compile 'com.tencent.bugly:crashreport:2.6.6' //其中latest.release指代最新Bugly SDK版本号，也可以指定明确的版本号，例如2.2.0

四、使用svn的话查看提交日志的时候，可能会出现下面的错误提示The working copy is too old(firmat10) to work with client version’1.9.5′

解决方案：

1、升级TortoiseSVN版本到1.10.1以上，去官网下载并安装即可。【步骤1，可以先不用执行，先执行步骤2，根据错误提示进行处理，因为我先执行的步骤1，所以执行步骤2的时候没有报错，所以不清楚是否步骤1必须执行】

查看本地TortoiseSVN版本号：空白处——鼠标右键——TortoiseSVN——About

点击Check For Updates…进行版本检查。

下载地址：https://tortoisesvn.net/downloads.html

下载安装步骤参考《【Android Studio安装部署系列】十九、Android studio使用SVN》

2、在Android Studio的terminal下输入：svn upgrade

3、没有错误代表正常，重新执行svn操作，比如查看提交日志，现在就正常了

五、Sync Project with Gradle Files图标的位置发生了变化，现在的位置如下图所示；其实从3.1.4开始就已经发生变化了
