Java 启动android应用程序从php文件读取SQL数据时出错

java php android sql-server web-services

Java 启动android应用程序从php文件读取SQL数据时出错,java,php,android,sql-server,web-services,Java,Php,Android,Sql Server,Web Services,我有一个使用php文件读取SQL Server中外部数据的程序。我制作了两个菜单项，比如新闻从MySQL获取数据和禁止列表从SQLServer获取数据。新闻菜单和禁止列表使用相同的代码。新闻菜单运行完美，没有任何错误，但当我运行禁止列表，程序自动关闭这样我我在logcat上看到了这样的错误 06-08 05:54:58.335 1276-1276/net.dragon_dev.www.dzoneconnect E/AndroidRuntime﹕ FATAL EXCEPTION: main
