Android Get real path

[danten]

Hello to everybody,
I need to get a real path to the file as ParamStr (1).
Now I get the file path as follows: /external/file/11608
I need to get the file path: /external/documents/mytext.txt

My code:

Delphi-Quellcode:

procedure TfrmMain.FormCreate(Sender: TObject);
var
  intent: JIntent;
  param_intent: Jnet_Uri;
  param_str: String;
begin

  intent := SharedActivity.getIntent;
  if intent <> nil then
  begin
    if TJIntent.JavaClass.ACTION_VIEW.equals(intent.getAction) then
    begin
      param_intent:= intent.getData;
      param_str:= JStringToString(param_intent.getEncodedPath.toString);
      Label4.Text := param_str;
    end;
  end;
end;

Thank you
