[問題]用AndroidAPP呼叫WebService

[aallens (ALLENS)]

各位大大好~
小弟想試著用AndroidAPP寫一個呼叫自己另外用.Net架設的WebService
但是似乎都沒有反應~
不知道是否哪邊出問題了?
下面的Code e.getMessage()都是空值~
所以我才又加一行~把button.text="xxx"
最後運行結果~Button的text都會變成xxx~表示真的有進入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~終於找到問題了!!!
Android 3.0以上~
要在OnCreate加上下面的資訊

        @SuppressLint("NewApi")        //這一行要加
        @TargetApi(Build.VERSION_CODES.GINGERBREAD) //這一行要加
        @Override

    protected void onCreate(Bundle savedInstanceState) {

        //這一整段都要加
         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());
        //--------------------------------------
}
