Those who are looking for Kotlin solution, can use this utility class. Here is the detailed article I have written on the topic. It uses OKHTTP3. Upload File to Server in Android Kotlin

package com.mvp.handyopinion

import android.app.Activity
import android.app.ProgressDialog
import android.net.Uri
import android.util.Log
import android.webkit.MimeTypeMap
import android.widget.Toast
import okhttp3.*
import okhttp3.MediaType.Companion.toMediaTypeOrNull
import okhttp3.RequestBody.Companion.asRequestBody
import java.io.File

class UploadUtility(activity: Activity) {

    var activity = activity;
    var dialog: ProgressDialog? = null
    var serverURL: String = "https://handyopinion.com/tutorials/UploadToServer.php"
    var serverUploadDirectoryPath: String = "https://handyopinion.com/tutorials/uploads/"
    val client = OkHttpClient()

    fun uploadFile(sourceFilePath: String, uploadedFileName: String? = null) {
        uploadFile(File(sourceFilePath), uploadedFileName)
    }

    fun uploadFile(sourceFileUri: Uri, uploadedFileName: String? = null) {
        val pathFromUri = URIPathHelper().getPath(activity,sourceFileUri)
        uploadFile(File(pathFromUri), uploadedFileName)
    }

    fun uploadFile(sourceFile: File, uploadedFileName: String? = null) {
        Thread {
            val mimeType = getMimeType(sourceFile);
            if (mimeType == null) {
                Log.e("file error", "Not able to get mime type")
                return@Thread
            }
            val fileName: String = if (uploadedFileName == null)  sourceFile.name else uploadedFileName
            toggleProgressDialog(true)
            try {
                val requestBody: RequestBody =
                    MultipartBody.Builder().setType(MultipartBody.FORM)
                        .addFormDataPart("uploaded_file", fileName,sourceFile.asRequestBody(mimeType.toMediaTypeOrNull()))
                        .build()

                val request: Request = Request.Builder().url(serverURL).post(requestBody).build()

                val response: Response = client.newCall(request).execute()

                if (response.isSuccessful) {
                    Log.d("File upload","success, path: $serverUploadDirectoryPath$fileName")
                    showToast("File uploaded successfully at $serverUploadDirectoryPath$fileName")
                } else {
                    Log.e("File upload", "failed")
                    showToast("File uploading failed")
                }
            } catch (ex: Exception) {
                ex.printStackTrace()
                Log.e("File upload", "failed")
                showToast("File uploading failed")
            }
            toggleProgressDialog(false)
        }.start()
    }

    // url = file path or whatever suitable URL you want.
    fun getMimeType(file: File): String? {
        var type: String? = null
        val extension = MimeTypeMap.getFileExtensionFromUrl(file.path)
        if (extension != null) {
            type = MimeTypeMap.getSingleton().getMimeTypeFromExtension(extension)
        }
        return type
    }

    fun showToast(message: String) {
        activity.runOnUiThread {
            Toast.makeText( activity, message, Toast.LENGTH_LONG ).show()
        }
    }

    fun toggleProgressDialog(show: Boolean) {
        activity.runOnUiThread {
            if (show) {
                dialog = ProgressDialog.show(activity, "", "Uploading file...", true);
            } else {
                dialog?.dismiss();
            }
        }
    }
