Android Gradle Apache HttpClient 不存在？

Question

我正在尝试将 IntelliJ 项目转换为 Android Studio 的 Gradle 系统，但我遇到了 Apache HttpClient 错误？我错过了什么吗，我得到的错误如下:

Error:(10, 30) error: package org.apache.http.client does not exist
Error:(11, 30) error: package org.apache.http.client does not exist

我的 build.gradle 文件有以下依赖:

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 或 Google 都没有解决方案，所以我希望这个问题能对 future 的搜索者有所帮助。

Answer 1

如果您使用 target sdk as 23 在您的 build.gradle 中添加以下代码

android{
    compileSdkVersion 23
    buildToolsVersion '23.0.1'
    useLibrary  'org.apache.http.legacy'
}

并将您的构建脚本更改为

classpath 'com.android.tools.build:gradle:1.3.0'
