Somebody has made the error when updating jForm.java file - the argument ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME
has nothing to do with Filename, and the result is that function GetFileNameByUri does not work anymore.
Restored back to original argument OpenableColumns.DISPLAY_NAME, now function GetFileNameByUri works as expected.
