Question

我使用.NET Web服务来绑定微调器。一旦我点击微调器，应用程序崩溃并从头开始。这是我的代码：

public void addItemsOnSpinner2() {
    try
    {
        SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
        envelope.dotNet = true;
        envelope.setOutputSoapObject(request);
        HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
        androidHttpTransport.call(SOAP_ACTION,envelope);
        Object soap = (SoapObject)envelope.getResponse();    

        tables = new Table[((SoapObject) soap).getPropertyCount()];
        for (int i = 0; i < tables.length; i++) {
            SoapObject pii = (SoapObject) ((SoapObject) soap).getProperty(i);
            Table t = new Table();
            t.Tableid = pii.getProperty(0).toString();
            t.Tablename = pii.getProperty(1).toString();

            tables[i] = t;
        }
    }
    catch (Exception e) {
        e.printStackTrace();
    }

    spinner1 = (Spinner)findViewById(R.id.spinner1);
    ArrayAdapter<Table> adapter = new ArrayAdapter<Table>(this, R.layout.spinner_layout, tables);
    adapter.setDropDownViewResource(R.layout.spinner_layout);
    spinner1.setAdapter(adapter);

}

以下是错误跟踪：

经过大量研究后我发现了解决方案。 webservice调用或代码没有任何问题。一切都很好，但我使用了以下代码

     StrictMode.setThreadPolicy(new StrictMode.ThreadPolicy.Builder()
     .detectDiskReads()
     .detectDiskWrites()
     .detectNetwork()   // or .detectAll() for all detectable problems
     .penaltyLog()
     .build());
     StrictMode.setVmPolicy(new StrictMode.VmPolicy.Builder()
     .detectLeakedSqlLiteObjects()
     .detectLeakedClosableObjects()
     .penaltyLog()
     .penaltyDeath()
     .build());
    setContentView(R.layout.activity_secondactivity);

我所做的只是评论以下一行

     .penaltyDeath()

只要在android中单击微调器，应用就会重新启动
