square - okhttp - OkHttpClient cannot be resolved
提问by charlesfranciscodev
Currently I am working on the Stormy Treehouse Android app. I want to use the square OkHttpClientbut I get an error "cannot resolve symbol okhttp3" when importing the class : import com.squareup.okhttp3.OkHttpClient;. Replacing okhttp3 with okhttp does not fix the error. Thanks for you help.
目前我正在开发Stormy Treehouse Android 应用程序。我想用方OkHttpClient但我得到一个错误“无法解析符号okhttp3”导入类时：import com.squareup.okhttp3.OkHttpClient;。用 okhttp 替换 okhttp3 不能修复错误。谢谢你的帮助。

package com.trainerworkout.stormy;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

import com.squareup.okhttp3.OkHttpClient;
public class MainActivity extends AppCompatActivity {
@Override

String apiKey = "f9d033c3cdeab16b95cecdeb6721a093";
double latitude = 45.5124;
double longitude = -73.5547;
String forecastUrl = "https://api.forecast.io/forecast/" + apiKey + "/" + latitude + "," + longitude;
// Cannot resolve symbol
OkHttpClient client = new OkHttpClient();
super.onCreate(savedInstanceState);

Try Removing your import, and just go to this line
尝试删除您的导入，然后转到这一行
OkHttpClient client = new OkHttpClient();
move your cursor to OkHttpClientand press Alt+Enter, you will see 2 classes to choose import from as you can see in this image:
将光标移至OkHttpClient并按 Alt+Enter，您将看到 2 个类可供选择导入，如下图所示：
So basically there are two types of imports available
所以基本上有两种类型的进口可用
1). import com.squareup.okhttp.OkHttpClient;
1）。 import com.squareup.okhttp.OkHttpClient;
2). import okhttp3.OkHttpClient;
2）。 import okhttp3.OkHttpClient;
and yours is matching none of them, Please try to import the correct one, depending upon your requirements.
并且您的不匹配，请根据您的要求尝试导入正确的。

I too faced same problem, try changing your dependencies in the gradle as following.
我也遇到了同样的问题，请尝试如下更改 gradle 中的依赖项。
**
**
dependencies {
依赖{
compile fileTree(dir: 'libs', include: ['*.jar'])
compile files('libs/okhttp-3.4.2.jar')
compile 'com.squareup.okhttp3:okhttp:3.4.2'
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:25.0.1'
testCompile 'junit:junit:4.12'
}
}

You have to add these two dependencies in your build.gradle(app) :
您必须在 build.gradle(app) 中添加这两个依赖项：
compile 'com.squareup.okhttp:okhttp:2.2.0'
编译'com.squareup.okhttp:okhttp:2.2.0'
compile 'com.squareup.okhttp:okhttp-urlconnection:2.0.0'
编译'com.squareup.okhttp:okhttp-urlconnection:2.0.0'
After that you will be able to install your application perfectly.
之后，您将能够完美地安装您的应用程序。
