要使用android 4.0.3中的教程,如果必须使用AsynxTasc,但我仍然不工作？
作者：互联网
我使用了教程http://www.c-sharpcorner.com/UploadFile/88b6e5/how-to-call-web-service-in-android-using-soap/,并为机器人4.0.3做了一些机会！
但它仍然没有！
有人能给我一个正确的解决方案吗？

语法错误,插入“enum Identifier”以完成EnumHeader
令牌“void”,@ expected上的语法错误
结果无法解析为变量FirstScreen.java

解决方法:
您无法访问DoInBackground()方法中的任何UI元素,因为它在自己的线程上运行,而不是在UI线程上运行.你应该用
txtFar.setText(result.getProperty(0).toString());
和
Toast.makeText(getApplicationContext(), "No Response",Toast.LENGTH_LONG).show();
调用onPostExecute或onProgressChanged()方法.
