public class SampleApplication extends Activity {

  private GraphControl graphControl;
  private GraphExtension graphExtension;

  @Override
  protected void onCreate( final Bundle savedInstanceState ) {

        super.onCreate(savedInstanceState);

アプリディレクトリに「libs」という名前のフォルダを作成し、そこに外部jarを配置します。EclipseのJavaビルドパスを修正してから、アプリを再構築（クリーン+ビルド）してください！私はこのようになくなった同様の問題を抱えていました。
