Attempted to load class "Media" from namespace "Application\MediaBundle\Entity" - php

Question

I want to add a profile picture to my admin class, but i got this error :
Attempted to load class "Media" from namespace "Application\MediaBundle\Entity".
Did you forget a "use" statement for e.g. "Sonata\MediaBundle\Model\Media", "Sonata\MediaBundle\Tests\Entity\Media", "Sonata\MediaBundle\Tests\Document\Media" or "Sonata\MediaBundle\Tests\PHPCR\Media"?
I searched a lot but no solution.
this is my code
user entity
> /**
> * #var \Application\Sonata\MediaBundle\Entity\Media
> * #ORM\ManyToOne(targetEntity="Application\Sonata\MediaBundle\Entity\Media",
> cascade={"persist"}, fetch="LAZY")
> */
> protected $media;
>
> /**
> * Set media
> *
> * #param \Application\Sonata\MediaBundle\Entity\Media $media
> * #return User
> */
> public function setMedia(\Application\Sonata\MediaBundle\Entity\Media $media = null)
> {
> $this->media = $media;
>
> return $this;
> }
>
> /**
> * Get media
> *
> * #return \Application\Sonata\MediaBundle\Entity\Media
> */
> public function getMedia()
> {
> return $this->media;
> }
user admin
/**
* #param \Sonata\AdminBundle\Form\FormMapper $formMapper
*
* #return void
*/
protected function configureFormFields(FormMapper $formMapper)
{
$formMapper
->with('General')
->add('username')
->add('email')
->add('enabled')
->add('firstname')
->add('lastname')
->add('plainPassword', 'password', array(
'required' => (!$this->getSubject() || is_null($this->getSubject()->getId())),
))
->add('media', 'sonata_media_type', array('provider' => 'sonata.media.provider.image', 'context' => 'engine', 'data_class' => 'Application\Sonata\MediaBundle\Entity\Media', 'required' => false))
->end();
}
