The java file is:

package com.yworks.android;

import android.app.Activity;
import android.os.Bundle;
import com.yworks.yfiles.ui.GraphControl;
import com.yworks.yfiles.ui.model.GraphExtension;
import com.yworks.yfiles.ui.model.IGraph;

/**
 * Getting Started - 01 Creating the View
 *
 * This demo simply introduces class {@link GraphControl}, the
 * central UI element for working with graphs in @PRODUCT@,
 * and {@link GraphExtension}, which provides convenience
 * methods for working with IGraphs.
 */
public class SampleApplication extends Activity {

  private GraphControl graphControl;
  private GraphExtension graphExtension;

  @Override
  protected void onCreate( final Bundle savedInstanceState ) {

        super.onCreate(savedInstanceState);
        // Sets the content view to the main layout loaded from
        // res/layout/main.xml
        setContentView(R.layout.main);
        // The GraphControl is declared in the loaded layout,
        // so now we can retrieve a reference to it
        graphControl = (GraphControl) findViewById(R.id.graphControl);
        // GraphExtension provides convenience methods
        // which are used in the following demos.
        graphExtension = new GraphExtension(graphControl.getGraph());

    // We'll initialize the app here in the following demos.
  }

  /**
   * Convenience property for getting the GraphControl's Graph
   * @return The GraphControls Graph
   */
  public IGraph getGraph() {
    return graphControl.getGraph();
  }

}

Thanks Regards iambilloo

在您的应用程序目录中创建一个名为“libs”的文件夹，并将您的外部 jar 放在那里。在 Eclipse 中更正 Java 构建路径，然后重建（清理+构建）您的应用程序！我有一个类似的问题，就这样消失了。
