这是我的logcat，问题是应用程序强制关闭，我想旋转导致此问题的行或方法。我是新来的android所以不能理解logcat的一个字。在此先感谢应用程序强制关闭

有点解释不会伤害（你的应用程序是什么，它什么时候发生等）。执行Manualloc.getCountries（第243行）时可能会引发NullPointerException，可能是在onCreate中。请发布方法代码getCountries – Guillaume 2012-01-16 12:23:37

看看你的Manualloc类中的第243行。在任何人都能正确回答这个问题之前，你需要用关于代码的其他信息来清楚地说明你的问题。 – 2012-01-16 12:24:09

感谢哥们，真的很急，所以不能发布完整的问题。但我整理出来了。该方法是从Web服务获取数据，我读的XML是带有一个null值的元素。已经排序。但是如果我困扰你，真的很抱歉。再也没有...... – samir 2012-02-02 12:08:13

你在270行中获得的方法的getCountries空指针异常，在课堂上Manualloc，您可以通过调试一下就行了对象为null检查存在，并相应地工作。

明白了jitendra。我试图从xml格式的web服务访问一个空对象。它是无效的。我将它分配给textview。 – samir 2012-02-02 12:09:12
