Android 用の jar ライブラリを含めるには、次の 2 つの方法が認められています。

  1. libs/プロジェクトのルートにあるフォルダーにライブラリを配置します。
  2. Include the library in your build path. If you choose this route, you will also need to export the library (Under Order and Exports in Eclipse).

ビルドパスを確認してください。ライブラリがビルドパスにない可能性があります。エラーは、クラスが見つからないことを明確に示しています。
