HttpClient 不会在 Android Studio 中导入 [英] HttpClient won't import in Android Studio

问题描述

我有一个用 Android Studio 编写的简单类:

I have a simple class written in Android Studio:

package com.mysite.myapp;

import org.apache.http.client.HttpClient;

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

由此我得到以下编译时错误:

and from this I get the following compile time error:

无法解析符号HttpClient

HttpClient 不是包含在 Android Studio SDK 中吗?即使不是，我也将它添加到我的 Gradle 构建中，如下所示:

Isn't HttpClient included in the Android Studio SDK? Even if it is not, I added it to my Gradle build like this:

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

有没有最后编译行，错误都是一样的.我错过了什么?

With or without the last compile line, the error is the same. What am I missing?

推荐答案

HttpClient is not supported in sdk 23. 您必须使用 URLConnection 或降级到 sdk22 (编译 'com.android.support:appcompat-v7:22.2.0')

HttpClient is not supported any more in sdk 23. You have to use URLConnection or downgrade to sdk 22 (compile 'com.android.support:appcompat-v7:22.2.0')

如果您需要 sdk 23，请将其添加到您的 gradle 中:

If you need sdk 23, add this to your gradle:

android {
    useLibrary 'org.apache.http.legacy'
}

您也可以尝试将 HttpClient jar 直接下载并包含到您的项目中或使用 OkHttp 代替

You also may try to download and include HttpClient jar directly into your project or use OkHttp instead
