How to extract the file name from URI returned from Intent.ACTION_GET_CONTENT?

by

developer.android.com has nice example code for this:
https://developer.android.com/guide/topics/providers/document-provider.html

A condensed version to just extract the file name (assuming “this” is an Activity):

public String getFileName(Uri uri) {
  String result = null;
  if (uri.getScheme().equals("content")) {
    Cursor cursor = getContentResolver().query(uri, null, null, null, null);
    try {
      if (cursor != null && cursor.moveToFirst()) {
        result = cursor.getString(cursor.getColumnIndex(OpenableColumns.DISPLAY_NAME));
      }
    } finally {
      cursor.close();
    }
  }
  if (result == null) {
    result = uri.getPath();
    int cut = result.lastIndexOf("https://stackoverflow.com/");
    if (cut != -1) {
      result = result.substring(cut + 1);
    }
  }
  return result;
}
