title: How to send string array data with okhttp MultipartBuilder data
body: <p>I am an android developer. I develop an application. I have a problem. I want to send string array data with okhttp multipart data. But I can not do it. Because "addFormDataPart" method is required string variable. I can not use that method(addFormDataPart). I want to send string array data. What can I do? </p>
  
  <p>Please help me.</p>
  
  <p>My source code:</p>
  
  <pre><code>private void String sendData(String serverURL, String[] arrayData){
  RequestBody requestBody;
  requestBody = new MultipartBuilder()
                          .type(MultipartBuilder.FORM)
                          .addFormDataPart("arraydata", arrayData)
                          .build();
  }
  </code></pre>
