Android retrofit 2, select video and upload to server

I'm trying to learn android, I'm ok at it right now not great. Trying to expand my skill set.

So I'm trying to get a video to upload to the server with retrofit. My retrofit works uploading EditText etc.. I'm using the same IP address here as I do there.

In the code the camera works fine records video and renames the video, I believe the select video works fine(not totally sure on that but gallery opens I select a video and it doesn't crash so..., and the PHP allows me to post a video using post man. But when I hit the upload button crash. I'm not sure if the issue is in getting the real path, in the retrofit code, or maybe my file select doesn't work? I need a better coder to help me out here. I been looking on overstack for days. Tried multiple examples. Just not getting it to work.
I can't figure out the error. I tried to throw some toasts in there to see if I am getting an error but I don't ever get a toast. Just a crash.
Here is my code. I'm at least trying, throw me a bone.

Slim/PHP index

$app->post('/saveFile', function(Request $request, Response $response)

$response = array();

if (isset($_POST['desc']) && ($_POST['ID']) && strlen($_POST['desc']) > 0 &&
$_FILES['image']['error'] === UPLOAD_ERR_OK)

$upload = new uploads();

$file = $_FILES['image']['tmp_name'];

$desc = $_POST['desc'];
$ID = $_POST['ID'];

if ($upload->saveFile($ID, $file,
getFileExtension($_FILES['image']['name']), $desc))
$response['error'] = false;
$response['message'] = 'File Uploaded Successfullly';


else
$response['error'] = true;
$response['message'] = 'Required parameters are not available';



echo json_encode($response);


);

function getFileExtension($file)

$path_parts = pathinfo($file);
return $path_parts['extension'];

Your controller method is all wrong, you have to use the Request / Response objects and than return the modified Response; My version is closer to the intended usage, but it is no way perfect, mostly because I don't have the android tools.

I hope it helps, more info here:
Request UploadedFiles HttpStatusCodes

$app->post('/saveFile', function(SlimHttpRequest $request, SlimHttpResponse $response)

$responseData = ;
$responseCode = 400;

/** @var PsrHttpMessageUploadedFileInterface $files */
$files = $request->getUploadedFiles();
/** @var string $postData */
$postData = $request->getParsedBody();

if ( !empty($postData['desc']) && ($postData['ID']) && !empty($files))
$upload = new uploads();

// use this if you are only upload one file
// otherwise loop though them all
$file = reset($files);

$desc = $postData['desc'];
$ID = $postData['ID'];

// this means the file was uploaded ok
if ( $file->getError() === UPLOAD_ERR_OK )
if ( $upload->saveFile($ID, $file, $file->getClientMediaType(), $desc) )
$responseData['error'] = false;
$responseData['message'] = 'File Uploaded Successfully';

$responseCode = 200;


else
$responseData['error'] = true;
$responseData['message'] = 'Required parameters are not available';

$responseCode = 406;


else
$responseData['error'] = true;
$responseData['message'] = 'File upload error: '. $file->getError();

$responseCode = 409;



return $response->withJson($responseData, $responseCode);
);


Uploads edit

class uploads


private $con;

public function __construct()

// you shouldn't need this if you are using Slim
// and you are doing require_once '/vendor/autoload.php' at the beginning of your
// index.php
require_once dirname(__FILE__) . '/DbConnect.php';

$db = new DbConnect();
$this->con = $db->connect();



public function saveFile($ID, PsrHttpMessageUploadedFileInterface $file, $extension, $desc)

$name = round(microtime(true) * 1000) . '.' . $extension;
$filedest = dirname(__FILE__) . UPLOAD_PATH . $name;

$file->moveTo($filedest);

$url = $server_ip = gethostbyname(gethostname());

$stmt = $this->con->prepare("INSERT INTO images (ID, description, url) VALUES (?, ?, ?)");
$stmt->bind_param("sss", $ID, $desc, $name);

return $stmt->execute();




$file

$file->moveTo($filedest)

move_uploaded_file
