我创建了java soap web服务并尝试将其与android app连接。我创建了一个表im databse作为登录并给出了字段。问题是我的android应用程序代码不是连接并获取数据。它显示没有错误的xml登录页面加载但没有按钮中的操作。如果我检查logcat没有错误。我已经发布了代码和logcat请尽快帮助我。

答案 0 :(得分：1)
显然，您没有看到任何错误，因为您在catch子句中没有任何代码。要查看可能错误的详细说明，请以这种方式修改代码（在DDMS中添加logcat过滤器 MyApp ）：
try {
androidHttpTransport.call(SOAP_ACTION, envelope);
SoapPrimitive response = (SoapPrimitive)envelope.getResponse();
TextView result = (TextView) findViewById(R.id.tv_status);
result.setText(response.toString());
}
catch(Exception e){
Log.i("MyApp", e.getMessage());
}
答案 1 :(得分：0)
请不要那样做
catch(Exception e){
}
因为那个
你的logcat是空的您可以使用
catch (Exception ex) {
ex.printStackTrace();
}
代替
答案 2 :(得分：0)
您需要检查您的logcat。首先包括 - Log.i("MyApp", e.getMessage()); in your catch and then you see the error and post your logcat to see what error you get
