Answer 1

Here is the multi part request class.

import java.io.File;
import java.io.IOException;

import org.apache.http.HttpStatus;

import android.content.Context;

import com.esp.ro.util.Config;
import com.esp.ro.util.Log;
import com.squareup.okhttp.MediaType;
import com.squareup.okhttp.MultipartBuilder;
import com.squareup.okhttp.OkHttpClient;
import com.squareup.okhttp.Request;
import com.squareup.okhttp.RequestBody;
import com.squareup.okhttp.Response;


public class MultipartRequest {

public Context caller;
public MultipartBuilder builder;
private OkHttpClient client;

public MultipartRequest(Context caller) {
    this.caller = caller;
    this.builder = new MultipartBuilder();
    this.builder.type(MultipartBuilder.FORM);
    this.client = new OkHttpClient();
}

public void addString(String name, String value) {
    this.builder.addFormDataPart(name, value);
}

public void addFile(String name, String filePath, String fileName) {
    this.builder.addFormDataPart(name, fileName, RequestBody.create(
            MediaType.parse("image/jpeg"), new File(filePath)));
}

public void addTXTFile(String name, String filePath, String fileName) {
    this.builder.addFormDataPart(name, fileName, RequestBody.create(
            MediaType.parse("text/plain"), new File(filePath)));
}

public void addZipFile(String name, String filePath, String fileName)
{
    this.builder.addFormDataPart(name, fileName, RequestBody.create(
           MediaType.parse("application/zip"), new File(filePath)));
}

public String execute(String url) {
    RequestBody requestBody = null;
    Request request = null;
    Response response = null;

    int code = 200;
    String strResponse = null;

    try {
        requestBody = this.builder.build();
        request = new Request.Builder().header("AUTH-KEY", Config.API_KEY)
                .url(url).post(requestBody).build();

        Log.print("::::::: REQ :: " + request);
        response = client.newCall(request).execute();
        Log.print("::::::: response :: " + response);

        if (!response.isSuccessful())
            throw new IOException();

        code = response.networkResponse().code();

        if (response.isSuccessful()) {
            strResponse = response.body().string();
        } else if (code == HttpStatus.SC_NOT_FOUND) {
            // ** "Invalid URL or Server not available, please try again" */
            strResponse = caller.getResources().getString(
                    R.string.error_invalid_URL);
        } else if (code == HttpStatus.SC_REQUEST_TIMEOUT) {
            // * "Connection timeout, please try again", */
            strResponse = caller.getResources().getString(
                    R.string.error_timeout);
        } else if (code == HttpStatus.SC_SERVICE_UNAVAILABLE) {
            // *
            // "Invalid URL or Server is not responding, please try again",
            // */
            strResponse = caller.getResources().getString(
                    R.string.error_server_not_responding);
        }
    } catch (Exception e) {
        Log.error("Exception", e);
        Log.print(e);
    } finally {
        requestBody = null;
        request = null;
        response = null;
        builder = null;
        if (client != null)
            client = null;
        System.gc();
    }
    return strResponse;
  }
}

Hope this help you.

Note : If you are using old OkHttp which is below version 3 then you can use this method.If you are using version 3 or above here is the answer for you.
