无法在Android Studio中解析符号HttpGet，HttpClient，DefaultHttpClient

问题描述：

我是我的应用程序中的android新手，正在与服务集成，因此当我导入所有这些jar文件时.它给出了一个错误:

Hi I am new for android in my app I am integrating with services so when I import all these jar files. It gives an error :

无法解析符号HttpGet，HttpClient，DefaultHttpClient.

Cannot resolve symbol HttpGet,HttpClient,DefaultHttpClient.

import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.DefaultHttpClient;

我的构建gradle:-

dependencies {

    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.0.1'
    compile 'com.android.support:design:23.0.1'
    compile 'org.apache.httpcomponents:httpcore:4.4.1'
    compile 'org.apache.httpcomponents:httpclient:4.5'
}

答

HttpClient在API级别22中已弃用，并在API级别23中已已删除.您必须使用URLConnection.

HttpClient was deprecated in API Level 22 and removed in API Level 23. You have to use URLConnection.

如果您仍然需要23，请将其添加到gradle ::

If you anyway need in 23, add this to your gradle::

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

注意:相反，我建议使用 OkHttp .

NOTE: Instead, I would recommend using OkHttp.
