How to upload .mp4 to server in Android Studio

Question

How do you upload a video (.mp4) file in the raw folder to a server on a button click in java android studio with minSdk 29.

Any help with this would be much appreciated.

This is what I have tried:

private void configureUploadButton() {
        uploadButton = findViewById(R.id.uploadButton);
        uploadButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                // creating a client
                OkHttpClient okHttpClient = new OkHttpClient();

                int videoResourceId = getResources().getIdentifier("name_of_video", "raw", getPackageName());
                Uri fileUri = Uri.parse("android.resource://" + getPackageName() + "/" + videoResourceId);
                Log.i("URI", "File URI: " + fileUri);

                File videoFile = new File(fileUri.getPath());
                Log.i("FILE_TAG", "File: " + videoFile + " Path: " + videoFile.getPath());

                RequestBody requestBody = RequestBody.create(MediaType.parse("video/mp4"), videoFile);
                MultipartBody multipartBody = new MultipartBody.Builder()
                        .setType(MultipartBody.FORM)
                        .addFormDataPart("video", videoFile.getName(), requestBody)
                        .build();

                Request request = new Request.Builder()
                        .url("http://10.0.2.2:5000/upload_video")
                        .post(multipartBody)
                        .build();

                okHttpClient.newCall(request).enqueue(new Callback() {
                    @Override
                    public void onFailure(@NonNull Call call, @NonNull IOException e) {
                        runOnUiThread(new Runnable() {
                            @Override
                            public void run() {
                                Log.i("SERVER_DOWN", "The sever is down: " + e.getMessage());
                                Toast.makeText(Record.this, "server down", Toast.LENGTH_SHORT).show();
                            }
                        });
                    }
                    @Override
                    public void onResponse(@NonNull Call call, @NonNull Response response) throws IOException {
                        runOnUiThread(new Runnable() {
                            @Override
                            public void run() {
                                int responseCode = response.code();
                                String responseMessage = response.message();
                                Log.i("RESPONSE", "Response code: " + responseCode + " Message: " + responseMessage);
                                if (response.isSuccessful()) {
                                    Toast.makeText(Record.this, "Connected to server successfully.", Toast.LENGTH_SHORT).show();
                                } else {
                                    Toast.makeText(Record.this, "Not able to connect to server.", Toast.LENGTH_SHORT).show();
                                }
                            }
                        });
                    }
                });
            }
        });
    }

I don't seem to be accessing the file correctly using the File class. The IOException that I am getting in the onFailure of the okHttpClient call is:

/2131689473: open failed: ENOENT (No such file or directory)

These are the permissions that I have in my Androidmanifest.xml

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.hardware.CAMERA" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>

You will acces app data specific folder through " getExternalFilesDir() " and your application data available in " sdcard =>Android => package.name => file.mp4 "

APIClient.java

public class APIClient {

private static Retrofit retrofit = null;

public static Retrofit getClient(){
    HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
    interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
    OkHttpClient client = new OkHttpClient.Builder()
            .hostnameVerifier(new HostnameVerifier() {
                @Override
                public boolean verify(String s, SSLSession sslSession) {
                    return true;
                }
            })
            .addInterceptor(interceptor)
            .build();

    retrofit = new Retrofit.Builder()
            .baseUrl("http://10.0.2.2:5000")
            .addConverterFactory(GsonConverterFactory.create())
            .client(client)
            .build();

    return retrofit;
}

}

APIInterface.java public interface APIInterface {

@Multipart
@POST("/api/UploadVideo")
Call<VideoUpload> chequeUpload(
                                @Part MultipartBody.Part video);

}

Model Class

public class VideoUpload {

 // Request
@SerializedName("video")
public String video;

// Response
  @SerializedName("Message")
  public String Message;

}

Upload video

video get from " Android " Specific folder sdcard =>Android => package.name => file.mp4

code.

   String root = getExternalFilesDir("/").getPath() + "/" + "Videos/";

   File videoFile = new File(root, "My_video" + ".mp4");

  RequestBody requestFile = RequestBody.create(MediaType.parse("multipart/form-data"), videoFile);

  MultipartBody.Part videoFileBody = MultipartBody.Part.createFormData("video", videoFile.getName(), requestFile);

    Call<VideoUpload> call = apiInterface.videoUploadNow(videoFileBody);

 call.enqueue(new Callback<VideoUpload>() {
        @Override
        public void onResponse(@NonNull Call<VideoUpload> call, @NonNull Response<VideoUpload> response) {
            pDialog.dismiss();
            if (response.isSuccessful()){
                VideoUpload uploadVideo = response.body();
             
             try {
                    JSONObject jsonObjectError = new JSONObject(response.errorBody().string());
                    showMessageInSnackbar(jsonObjectError.getString("Message"));
                } catch (JSONException e) {
                    e.printStackTrace();
                } catch (IOException e) {
                    e.printStackTrace();
                }


            }else{
                try {
                    JSONObject jsonObjectError = new JSONObject(response.errorBody().string());
                    showMessageInSnackbar(jsonObjectError.getString("Message"));
                } catch (JSONException e) {
                    e.printStackTrace();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }

        @Override
        public void onFailure(@NonNull Call<VideoUpload> call, @NonNull Throwable t) {
            if(t instanceof SocketTimeoutException){
                timeOutDialog.show();
            }
            pDialog.dismiss();
        }
    });
