相关疑难解决方法(0)

我有一个用Android Studio编写的简单类:

package com.mysite.myapp;

import org.apache.http.client.HttpClient;

public class Whatever {
    public void headBangingAgainstTheWallExample () {
        HttpClient client = new DefaultHttpClient();
    }
}

从这里我得到以下编译时错误:

Cannot resolve symbol HttpClient

不HttpClient包含在Android Studio SDK中？即使不是,我也将它添加到我的Gradle构建中:

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:23.0.0'
    compile 'org.apache.httpcomponents:httpclient:4.5'
}

无论有没有最后一个编译行,错误都是一样的.我错过了什么？
