SWT/LogCat中的錯誤？或Android 2.2 AVD

Question

基於提示，我將Android應用的目標從2.3更改爲2.2。

從平底鍋裏進入火中！

現在我的應用程序，甚至會無法打開（在2.2模擬器），我得到這個（似乎是一個SWT的問題，再一個Android/logcat的問題）：

Answer 1

http://www.vogella.de/articles/SWT/article.html似乎是一個可靠的教程。

從這個教程：

import org.eclipse.swt.widgets.Display; 
import org.eclipse.swt.widgets.Shell; 

public class FirstSWTApplication { 

public static void main(String[] args) { 
    Display display = new Display(); 
    Shell shell = new Shell(display); 
    shell.open(); 
    while (!shell.isDisposed()) { 
     if (!display.readAndDispatch()) 
      display.sleep(); 
    } 
    display.dispose(); 
} 

}

請注意，在清單org.eclipse.swt。
