title: Which Okhttp.jar version should I use with retrofit-2.0.1.jar?
body: <p>I'm using the latest version of Retrofit through Gradle, and it works like a charm (<code>compile 'com.squareup.retrofit2:retrofit:2.0.1'</code>).</p>
  
  <p>I wanted to use the .jar version, so I can include the library directly inside my app: I downloaded the <code>retrofit-2.0.1.jar.</code></p>
  
  <p>I got an error on <code>retrofit2.converter.gson.GsonConverterFactory</code> that was not found anymore. I include the <code>converter-gson-2.0.1.jar</code>, but now I have an error with Okhttp at runtime:</p>
  
  <pre><code>java.lang.NoClassDefFoundError: Failed resolution of: Lokio/Okio;
  </code></pre>
  
  <p>I've tried <code>okhttp-3.0.1.jar</code> and <code>okhttp-3.2.0.jar</code>, but none of them correct the error...</p>
  
  <p>Which .jar should I add to have the retrofit2 without any Gradle/maven dependencies?</p>
  
  <p>My phone is on Android L, I think the problem might come from there.</p>
