I just tried to use achartengine demo, but every time I click on something to show the chart appears an error saying \"The application AChartengine has stopped unexpectedly.

Answer 1

if you want to know how achartengine work then add the achartengine 0.7.0 jar to libs folder and link it with your project also have these below activity.

public class GeneratedChartDemo extends ListActivity {
  private static final int SERIES_NR = 2;

  private String[] mMenuText;

  /** Called when the activity is first created. */
  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    // I know, I know, this should go into strings.xml and accessed using
    // getString(R.string....)
    mMenuText = new String[] { "Line chart", "Scatter chart", "Time chart", "Bar chart" };
   setListAdapter(new SimpleAdapter(this, getListValues(), android.R.layout.simple_list_item_1,
        new String[] { "name"}, new int[] { android.R.id.text1 }));
  }

  private List> getListValues() {
    List> values = new ArrayList>();
    int length = mMenuText.length;
    for (int i = 0; i < length; i++) {
      Map v = new HashMap();
      v.put("name", mMenuText[i]);
      values.add(v);
    }
    return values;
  }
