Ich benutze Android Studio, um eine App zu erstellen, die eine GET-Anfrage an einen Server sendet. Mein Code lautet:

import org.apache.http.client.methods.CloseableHttpResponse;  
import org.apache.http.client.methods.HttpGetHC4;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;

public class HTTPHelper
{
    private String base;

    public HTTPHelper (String base)
    {
        this.base = base;
    }

    public String doGet (String path)
    {
        try
        {
            CloseableHttpClient client = HttpClientBuilder.create().build();
            HttpGetHC4 get = new HttpGetHC4(path);
            CloseableHttpResponse response = client.execute(get);

            return "";
        }
        catch (Exception e)
        {
            return null;
        }
    }
}

Das Problem ist, dass Android Studio die Zeile markiert

client.execute(get);

mit einem Fehler:

saying "Kein Zugriff auf org.apache.http.client.HttpClient"

Hier ist meine Gradle-Datei:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.0"

    defaultConfig {
        applicationId "principal.halloween"
        minSdkVersion 16
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:23.0.0'
    compile 'com.pubnub:pubnub-android:3.7.5'

    compile group: 'org.apache.httpcomponents' , name: 'httpclient-android' , version: '4.3.5.1'
