应用工作在模拟器，但不是在设备

Question

我有这个班我的应用程序：

1. NewsApp.java
2. ScreenApp.java
3. Item.java
4. ui/TableList.java

该应用程序检索列表来自web服务（.net）的链接，我使用KSoap库（作为参考项目）。

我用JDE 4.5开发，因为与Eclipse我不能使用的方法“setRowHeight（索引，INT）” ListField类的，那么我就需要用JDE 4.5

好吧，我编译应用程序（F7键），然后在模拟器（F5键）中运行。 在模拟器中，转到图标应用程序，并尝试打开...没有发生...应用程序未打开...很奇怪...没有错误消息（ScreenApp.java第57行）...但.. 。如果我再多几分钟...我看到错误信息（ScreenApp.java第57行）...我想也许是因为应用程序尝试连接...

后来...我想是因为不存在在模拟器中的互联网连接（我看到模拟器顶部的EDGE ...很奇怪），我停止模拟器，打开MDS，并再次运行模拟器（F5键），现在工作...列表显示正确.. 。我可以打开黑莓浏览器中的链接。现在

...我把所有编译后的文件在同一目录下，创建一个ALX文件：

1. NewsApp.alx 并在设备上安装此应用，工程安装好了，我去的应用程序列表上设备（8520），打开应用程序，我看到连接消息（ScreenApp.java第57行）; 我不明白为什么？在这个电话（8​​520）我有我的运营商的EDGE连接，我有WIFI活动...我可以浏览任何网页（默认浏览器）...但我的应用程序不能从webservice检索信息... :(

有人帮帮我好吗？

您需要在网址的结尾，当在设备上运行的应用程序。

对于离，在无线网络的情况下，就需要追加使用不同的连接参数; interface = wifi“ at the end of the URL。

详细代码是：您需要根据设备网络调用getConnectionString（）来获取连接sufix。我希望这会解决你的问题。
