Android Intent problem

Hey guys,
I'm having problem on scanning media, after capture screenshot from unity with Vuforia QCAR.
I manage to capture and move the file to a folder, but unable to make it appear in gallery.

I'm not familiar with NDK or programming outside Unity.
I have two (2) javascript (.js),
> Screenshot.js (Assets/Scripts)
> RescanMedia.js (Assets/Plugins/Android)

So my Screenshot does the usual stuff,
>Application.CaptureScreenshot("file.png");
>check for file existent on Application.persistentDataPath
>move to a folder (mnt/sdcard/Pictures/ABC)
>RescanMedia.ScanNow("file://mnt/sdcard/Pictures/ABC/file.png");

This is the RescanMedia.js

Code (csharp):

1.  
2. #pragma strict
3.  
4. #if UNITY_ANDROID
5. static function ScanNow(uriString : String) {
6. print("here1");
7. var uriClass = AndroidJavaClass("android.net.Uri");
8.  
9. print("here2");
10. var uri = uriClass.CallStatic.<AndroidJavaObject>("parse", uriString);
11.  
12. print("here3");
13. var intent = AndroidJavaObject("android.intent.action", "android.intent.action.media_mounted", uri);
14.  
15. print("here4");
16. var unityPlayerClass = AndroidJavaClass("com.qualcomm.QCARUnityPlayer.QCARPlayerActivity");
17.  
18. print("here5");
19. var currentActivity = unityPlayerClass.GetStatic.<AndroidJavaObject>("currentActivity");
20.  
21. print("here6");
22. currentActivity.Call("sendBroadcast", intent);
23. }
24. #endif
25.  

So basically, I'm trying to replicated this line of code to rescan my file.png

Code (csharp):

1.  
2. sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED, Uri.parse("file://" + Environment.getExternalStorageDirectory())));
3.  

And I get this error on logcat

Code (csharp):

1.  
2. .
3. ..
4. ...
5. here3
6. JNI ERROR (app bug): accessed stale weak global reference 0x13 (index 4 in a table of size 0)
7. VM aborting
8. ...
9. ..
10. .
11.  

I still using the Android manifest provided by QCAR. Do I need to make any changes in there?
If anyone have know how to make the picture appear in gallery, I would appreciate a tentative guide.

cheers,

Is ok for now..
I get things work fine.

Code (csharp):

1.  
2. Debug.Log("**create activity instance");
3. AndroidJavaClass classPlayer = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
4. AndroidJavaObject objActivity = classPlayer.GetStatic<AndroidJavaObject>("currentActivity");
5.        
6. Debug.Log("**create Uri class");
7. AndroidJavaClass classUri = new AndroidJavaClass("android.net.Uri");
8.        
9. Debug.Log("**create Intent object");
10. AndroidJavaObject objIntent = new AndroidJavaObject("android.content.Intent", new object[2]{"android.intent.action.MEDIA_MOUNTED", classUri.CallStatic<AndroidJavaObject>("parse", "file:///mnt/sdcard/TestFolder/SubFolder/" + filename)});
11.        
12. Debug.Log("**call sendBroadcast");
13. objActivity.Call ("sendBroadcast", objIntent);
14.  

 

does any one can convert this code to javascript ?

 

This works great! Thanks!
