Ứng dụng AChartengine đã dừng đột ngột. Vui lòng thử lại

Question

Tôi chỉ cố gắng sử dụng bản demo achartengine, nhưng mỗi khi tôi nhấp vào một cái gì đó để hiển thị biểu đồ sẽ xuất hiện lỗi "Ứng dụng AChartengine đã dừng đột ngột. Vui lòng thử lại". Có người biết nói cho tôi biết làm thế nào tôi có thể làm? Tôi làm theo các hướng dẫn gợi ý trong trang này http://www.achartengine.org/content/goodies.html và tôi sử dụng một tiêu chuẩn giả lập với mức api 7. Tôi có các lỗi này:

Xem này cho một giải pháp cho điều này: http://groups.google.com/group/achartengine/browse_thread/thread/4cb1efddad3c19d0/2b59e5164e05c469#2b59e5164e05c469

Trích:

Trong Eclipse: -> Nhấp chuột phải dự án của bạn - hãy để xây dựng con đường - chọn Định cấu hình đường dẫn xây dựng -> chuyển đến tab "Đặt hàng và xuất" -> Kiểm tra "achartengine-1.0.0 .jar hộp và sau đó nhấp chuột duy nhất tên của nó -> di chuyển nó lên để bên phải của nó dưới sự phụ thuộc Android (đôi khi điều này có thể tạo sự khác biệt nếu bạn có nhiều Chum)

bấm ok sau đó làm sạch dự án của bạn. (Project -> Clean ...)

Hãy thử chạy lại và xem điều đó có hữu ích không.

Answer 2

nếu bạn muốn biết làm thế nào công việc achartengine sau đó thêm jar achartengine 0.7.0 để libs thư mục và liên kết nó với dự án của bạn cũng có những hoạt động dưới đây.

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++) {
