标题[问题]用AndroidAPP呼叫WebService
时间Wed Jun 4 08:26:40 2014
各位大大好~
小弟想试着用AndroidAPP写一个呼叫自己另外用.Net架设的WebService
但是似乎都没有反应~
不知道是否哪边出问题了?
下面的Code e.getMessage()都是空值~
所以我才又加一行~把button.text="xxx"
最後运行结果~Button的text都会变成xxx~表示真的有进入exception~
Code如下：
public void doSomething(View v)
{
Button btn = null;
btn=(Button)findViewById(R.id.button1);
String NAMESPACE = "
http://tempuri.org/";
String URL = "
http://127.0.0.1:2282/service1.asmx";
String SOAP_ACTION = "
http://tempuri.org/HelloWorld";
String METHOD_NAME="HelloWorld";
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.dotNet=true;
envelope.setOutputSoapObject(request);
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
try
{
androidHttpTransport.call(SOAP_ACTION, envelope);
SoapPrimitive result = (SoapPrimitive)envelope.getResponse();
btn.setText(result.toString());
}
catch(Exception e)
{
e.printStackTrace();
btn.setText(e.getMessage());
btn.setText("xxx");
}
}
---------------------------------------------------------------------
找了一整天~终於找到问题了!!!
Android 3.0以上~
要在OnCreate加上下面的资讯
@SuppressLint("NewApi") //这一行要加
@TargetApi(Build.VERSION_CODES.GINGERBREAD) //这一行要加
@Override
protected void onCreate(Bundle savedInstanceState) {
//这一整段都要加
StrictMode.setThreadPolicy(new StrictMode.ThreadPolicy.Builder()
.detectDiskReads()
.detectDiskWrites()
.detectNetwork() // or .detectAll() for all detectable problems
.penaltyLog()
.build());
StrictMode.setVmPolicy(new StrictMode.VmPolicy.Builder()
.detectLeakedSqlLiteObjects()
.penaltyLog()
.penaltyDeath()
.build());
//--------------------------------------
}
