How can I get the filename of a treeUri object?

I want to load a BGRABitmap with the data of the chosen file.

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure
TAndroidModule1.AndroidModule1ActivityResult(Sender: TObject; 
requestCode: integer; resultCode: TAndroidResult; intentData:
jObject);var  treeUri: jObject;  arrayData: TDynArrayOfString; 
listData: TstringList;  count, i: integer;  contentText: string;  
outFileName, outUriValue: string;begin   if resultCode = RESULT_OK
then   begin       if intentData = nil then      begin       
 ShowMessage('Sorry... data nil received...');         Exit;     
end;       treeUri:= IntentManager1.GetDataUri(intentData);      
//ShowMessage('dataUri = ' +
IntentManager1.GetDataUriAsString(intentData) );       if treeUri =
nil then      begin         ShowMessage('Sorry... Uri nil
received...');         Exit;      end; //      ShowMessage('treeUri ='
+Self.UriToString(treeUri));      
//Self.TakePersistableUriPermission(treeUri); //so, you don't need a
new request for user when app resume from background       if
requestCode = 111 then  //create file      begin       
 ShowMessage('Success! Created File!');          //Add content...    
   Self.SaveTextToUri('1. Hello Android 11 World!' + sLineBreak,
treeUri);      end;       if requestCode = 222 then  //open file     
begin          ShowMessage('Success! Open File!');        
 //contentText:= Self.GetTextFromUri(treeUri); //get content       
 //ShowMessage(contentText);          //Add content..       
 //Self.SaveTextToUri(contentText + '2. New Text Content!' +
sLineBreak , treeUri);           // or....       
 //IntentManager1.SetAction(iaView);       
 //IntentManager1.SetDataAndType(treeUri, 'text/plain');       
 //IntentManager1.StartActivity();          //or if mimetype is
"image/*"       
 ImageView1.SetImage(Self.GetBitmapFromUri(treeUri));        
 width:=imageview1.GetBitmapWidth;       
 height:=imageview1.GetBitmapHeight;          bmp :=
TBGRABitmap.Create(width, Height);       
 bmp.LoadFromFile(Self.UriToString(treeUri));       
 //ShowMessage('LoadFromFile : treeUri ='
+Self.UriToString(treeUri));          Self.Refresh;                  
 //or         //IntentManager1.SetAction(iaView);       
 //IntentManager1.SetDataAndType(treeUri, 'image/*');       
 //IntentManager1.StartActivity();       end;       if requestCode =
333 then  //open directory tree      begin         arrayData:=
Self.GetFileList(treeUri, '.txt'); //filter by file extension        
//or        //arrayData:= Self.GetFileList(treeUri); // no filter    
   listData:= Self.ToStringList(arrayData, ' ');         count:=
listData.Count;        for i:= 0 to count-1 do        begin         
listData.GetNameValue(i , outFileName, outUriValue);         
//ListView1.Add(outFileName);         
//ListView1.SetItemTagString(outUriValue, i); //hiden information    
  end;         SetLength(arrayData, 0);        listData.Free;      
end;   end;end;

OK,

Found a solution :

function GetBitmapFromUri
