ライブラリ smslib を Windows マシンにインストールしました。ライブラリのセットアップについては、Web サイト smslib.org のすべての指示に従いました。しかし、SendMessage の例を実行しようとすると、エラーが発生しました。

チェックリスト:-

  • javax.comm.properties を追加し、
  • Win32.dll ファイル (これらはモデムと通信するために必要です)
  • smslib jar
  • 互換性のあるモデムがあることを確認してください。アンドロイドのスマホが動かない。内蔵モデムまたは usb-GSM モデムを備えた特定の古い学校のモデルが必要です。
  • パッケージに他のクラスはありますか?
