pick image from android gallery

Hello. I'm searching a way to load image from android gallery. I'm found that: http://answers.unity3d.com/questions/537476/open-gallery-android.html

but it is just open gallery. After a little work I simple modified it:

  public void OpenAndroidGallery()
     {
         #region [ Intent intent = new Intent(); ]
         //instantiate the class Intent
         AndroidJavaClass intentClass = new AndroidJavaClass("android.content.Intent");
         
              //instantiate the object Intent
              AndroidJavaObject intentObject = new AndroidJavaObject("android.content.Intent");
         #endregion [ Intent intent = new Intent(); ]
 
 
         #region [ intent.setAction(Intent.ACTION_GET_CONTENT); ]
         //call setAction setting ACTION_SEND as parameter
         intentObject.Call<AndroidJavaObject>("setAction", intentClass.GetStatic<string>("ACTION_GET_CONTENT"));
         #endregion [ intent.setAction(Intent.ACTION_GET_CONTENT); ]
 
 
         #region [ intent.setData(Uri.parse("content://media/internal/images/media")); ]
         //instantiate the class Uri
         AndroidJavaClass uriClass = new AndroidJavaClass("android.net.Uri");
 
         //instantiate the object Uri with the parse of the url's file
         AndroidJavaObject uriObject = uriClass.CallStatic<AndroidJavaObject>("parse", "content://media/internal/images/media");
 
         //call putExtra with the uri object of the file
         intentObject.Call<AndroidJavaObject>("putExtra", intentClass.GetStatic<string>("EXTRA_STREAM"), uriObject);
         #endregion [ intent.setData(Uri.parse("content://media/internal/images/media")); ]
         
              //set the type of file
              intentObject.Call<AndroidJavaObject>("setType", "image/jpeg");
 
         #region [ startActivityForResult(intent , 1); ]
         //instantiate the class UnityPlayer
         AndroidJavaClass unity = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
 
         //instantiate the object currentActivity
         AndroidJavaObject currentActivity = unity.GetStatic<AndroidJavaObject>("currentActivity");
         
              //call the activity with our Intent
              currentActivity.Call("startActivity", intentObject);
         #endregion [ startActivityForResult(intent , 1); ]
     }

Now it open gallery and I can choose image. Look at the last region. But how I can use it as a texture for example? How catch uri of image?

I think I can use some of unity assets, but now I try to implement it without assets. And I hope it would be interesting for other beginners.
