NDK versions 16 and below cannot be downloaded

[tumatanquang]

When downloading NDK version 16 or lower, for example:

 - name: Setup Android NDK
  uses: nttld/setup-ndk@v1
  id: setup-ndk
    with:
      ndk-version: r9d
      add-to-path: false

You will receive the error: Error: Unexpected HTTP response: 404.

Do you happen to have an example of what the download links for these old versions look like ?
