androidstudio配置：

异常：Failed resolutionof:Lokhttp3/OkHttpClient;

解决方法：添加依赖项：

compile files('libs/okhttp-3.3.1.jar')
compile 'com.squareup.okhttp:okhttp:2.0.0'

异常：Failed resolutionof:Lokio/ForwardingTimeout;

解决方法：添加依赖项：

compile files('libs/okio-1.6.0.jar')

异常：Duplicatefiles copied in APKMETA-INF/maven/com.squareup.okio/okio/pom.properties

还需要build.gradle添加：

packagingOptions {
    exclude 'META-INF/NOTICE.txt'
  exclude'META-INF/LICENSE.txt'
    exclude 'META-INF/DEPENDENCIES.txt'
    exclude 'META-INF/NOTICE'
    exclude 'META-INF/LICENSE'
    exclude 'META-INF/DEPENDENCIES'
    exclude 'META-INF/dependencies.txt'
    exclude 'META-INF/maven/com.squareup.okhttp/okhttp/pom.xml'
    exclude 'META-INF/maven/com.squareup.okhttp/okhttp/pom.properties'
    exclude 'META-INF/maven/com.squareup.okio/okio/pom.xml'
    exclude 'META-INF/maven/com.squareup.okio/okio/pom.properties'
}

简单封装：

https://github.com/neil2hw/OkHttpManager/blob/master/OkHttpManager.java

使用例子：

OkHttpClient client = new OkHttpClient();

URL url = null;
try {
   url = new URL("http://blog.csdn.net/gaolu");
   Request request = new Request.Builder().url(url).build();

   Response response =client.newCall(request).execute();
   String aaa = response.body().string();
   Log.e("aaa",aaa);
} catch (MalformedURLException e1) {
   e1.printStackTrace();
} catch (IOException e1) {
   e1.printStackTrace();
}

使用例子：

String url ="http://www.csdn.net/";

OkHttpUtils

.get()

.url(url)

.addParams("username", "hyman")

.addParams("password", "123")

.build()

.execute(newStringCallback()

{

@Overridepublicvoid onError(Request request, Exception e)

{

}

@Overridepublicvoid onResponse(String response)

{

}

});
