我试图将IntelliJ项目转换为Android Studio的Gradle系统，但我遇到了Apache HttpClient错误?我是否遗漏了一些东西，我得到的错误如下:
Error:(10, 30) error: package org.apache.http.client does not exist

我的建立。Gradle文件有以下依赖项:
dependencies {
compile 'com.google.android.gms:play-services:+'
compile 'org.apache.httpcomponents:httpclient:4.2.6'
compile 'org.apache.httpcomponents:httpmime:4.2.6'
compile files('libs/core.jar')
}
似乎很多人都遇到了类似的问题，但SO和谷歌都没有解决方案，所以我希望这个问题能帮助未来的搜索者。
我建议你用新的HttpURLConnection替换已弃用的apache HttpClient。
这是一个更干净的解决方案，很容易迁移，通常最好坚持最新的SDK更改，而不是试图破解/修补/变通:你通常会后悔:)
步骤1
HttpGet httpGet = new HttpGet(url);
就变成:
URL urlObj = new URL(url);
步骤2
HttpClient httpClient = new DefaultHttpClient();
HttpContext localContext = new BasicHttpContext();
HttpResponse response = httpClient.execute(httpGet, localContext);
InputStream is = response.getEntity().getContent();
就变成:
HttpURLConnection urlConnection = (HttpURLConnection) urlObj.openConnection();
InputStream is = urlConnection.getInputStream();
一步两步
int status = response.getStatusLine().getStatusCode();
就变成:
int status = urlConnection.getResponseCode();

我不得不发帖，因为上面的答案都不完全适合我。
我正在使用Android Studio
classpath 'com.android.tools.build:gradle:1.5.0'
compileSdkVersion 23
buildToolsVersion "23.0.3"
步骤1:下载最新的jar文件(http://www-eu.apache.org/dist//httpcomponents/httpclient/binary/httpcomponents-client-4.5.2-bin.zip)
第二步:复制粘贴.jar文件到你的模块(可以是app或library)中的libs文件夹(如果不存在就创建)
步骤3:右键单击jar并“添加为库”。它会自动将jar文件作为依赖项添加到模块的gradle文件中
第4步:现在你的问题会自动得到解决，但如果你在你的应用程序中使用proguard，它会给你关于重复类文件的警告，不会让你构建。这是一个已知的错误，您需要在您的proguard-rules中添加以下内容
-dontwarn org.apache.commons.**
-keep class org.apache.http.** { *; }
-dontwarn org.apache.http.**
好运！
