Android Question Get path/filename from STREAM for FTP

I haven't used intents or data streams before, so this is a little new to me. Basically I want to be able to share pictures from gallery via FTP. I have managed to get my app to show in the Share list on gallery and it loads the desired activity when I share. I have logged the starting intent and it's extras and here is an example

** Activity (shareftp) Create, isFirst = true **
** Activity (shareftp) Resume **
(Intent) Intent { act=android.intent.action.SEND_MULTIPLE typ=image/* flg=0x1 cmp=barxdroid.fotop/.shareftp (has clip) (has extras) }
Bundle[{android.intent.extra.STREAM=[content://media/external/images/media/6616, content://media/external/images/media/6615], exit_on_sent=true}]
The server error usually happens when the server security software "decides" that the text is a SQL injection. You can upload the text as a file instead.

You can get the path to the actual file with the code I posted here: http://www.b4x.com/android/forum/threads/uri-content-media-to-real-file.13473/#content
Bundle extras = getIntent().getExtras();
if(extras !=null){String datas= extras.getString("EXTRA_ID");
if(datas!=null){// do stuff}
Dim jIntent As JavaObject = StartingIntent
Dim bundle As JavaObject = jIntent.RunMethod("getExtras", Null)
Dim links() As String = bundle.RunMethod("getStringArrayExtra", Array As Object("android.intent.extra.STREAM"))
For Each link As String In Links
 Log(link)

I tried changing 'getStringArrayExtra' to 'getParcelableArrayListExtra' and bascially the same error but referencing getParcelableArrayListExtra.

any other ideas?


   if (Intent.ACTION_SEND_MULTIPLE.equals(action)) && Intent.hasExtra(Intent.EXTRA_STREAM)) {
    ArrayList list = intent.getParcelableArrayListExtra(Intent.EXTRA_STREAM);
    for (Parcelable p : list) {
        Uri uri = (Uri) p;
        /// do something with it.
If StartingIntent.Action = "android.intent.action.SEND_MULTIPLE" AND StartingIntent.HasExtra("android.intent.extra.STREAM") Then
 Dim jIntent As JavaObject = StartingIntent
 Dim List1 As List = jIntent.RunMethod("getParcelableArrayListExtra", Array As Object("android.intent.extra.STREAM")
 For Each u As Uri In List1
  Log(u)
End If
Awesome, that part is working. Now when I pass a uri to the function copied from http://www.b4x.com/android/forum/threads/uri-content-media-to-real-file.13473/#post-76176

I get an error as the Cursor is not initializing. 

I'm assuming it is to do with this line

in that I am looking at a 'stream'. Tried changing _data to _stream and _STREAM. No joy. Feeling such a n00b....

    Try a different approach.
    

    Use File.Copy("ContentDir", YourUri, File.DirInternalCache, "sometempfile") 'ContentDir is a special alias
    

    Now upload the temporary file.
   
   
    OK, things took a little twist. The first bit of code that I reported as working, worked fine when sharing multiple images, but the list was not initialized if just 1 image was shared.
    

    In the end I managed to put together a little library that takes care of both.
    

    Not sure if the lib will be of use to anyone else and I struggled with what to call it.
    

    Currently lib called UriTools:
    

    2 methods
    

    getRealPathFromUri - returns a full path from uri. Left public for just in case.
    

    getPathsFromIntent - pass an intent with uri(s) as extras. Extracts uri(s) and then uses above method to convert the uri(s) to paths. Returns a List of Full Paths.
    

    If anyone thinks it would be a good idea to upload, just shout. Also, if you have a better name........
   
   I use your UriTools library.
   

   I have found a problem with Android 6.0 and Gallery.
   

   getPathsFromIntent fails with Gallery, but works fine with others apps.
   

   With Gallery it detect multiple items, when I share a single item, and crash with a "null object reference"
   

   listaA= ut.getPathsFromIntent (in)
        If listaA.IsInitialized Then
            For Each pfile As String In listaA
                Utilidades.AlmacenaAdj (pfile)
            VisibleTab (1)
        End If
