應用程序AChartengine意外停止。請重試

Question

我只是試圖用achartengine演示，但我每次點擊的東西顯示在圖表上會出現一個錯誤，說「AChartengine意外停止的應用程序，請重試」。有人知道告訴我，我該怎麼辦？我跟着http://www.achartengine.org/content/goodies.html此頁面上提示的說明，我用API 7級仿真器的標準我有這些錯誤：

爲解決這一看到這個： http://groups.google.com/group/achartengine/browse_thread/thread/4cb1efddad3c19d0/2b59e5164e05c469#2b59e5164e05c469

在Eclipse： - >右鍵單擊您的項目 - 去構建路徑 - 選擇配置構建路徑 - >進入「排序和導出」選項卡 - >檢查「achartengine-1.0.0的.jar框，然後只需點擊一下，它的名字 - >動它，以便其Android的依賴關係右下（有時這 可以有所作爲，如果你有多個JAR）

單擊確定，然後清理項目。 （項目 - >清除...）

嘗試再次運行一下，看看有沒有什麼幫助。

，如果你想知道如何achartengine工作那麼achartengine 0.7.0 jar添加到庫文件夾並將其與您的項目鏈接也有以下活動。

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