Ошибка в SWT / LogCat?или Android 2.2 AVD

0 голосов
/ 25 ноября 2011

Исходя из подсказки, я изменил цель моего приложения для Android с 2.3 на 2.2.

Из сковороды и в огонь!

Теперь мое приложение не будет дажеоткрыть (в эмуляторе 2.2), и я получаю это (кажется, проблема SWT, а затем проблема Android / LogCat): 

eclipse.buildId=M20110909-1335
java.version=1.7.0_01
java.vendor=Oracle Corporation
BootLoader constants: OS=win32, ARCH=x86_64, WS=win32, NL=en_US
Framework arguments:  -product org.eclipse.epp.package.java.product
Command-line arguments:  -os win32 -ws win32 -arch x86_64 -product org.eclipse.epp.package.java.product

http://www.vogella.de/articles/SWT/article.html, похоже, хороший учебник.

Из этого урока: 

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();
}

}

Не забудьте включить в манифест org.eclipse.swt.
