Error java.lang.outofmemory (web services) on android

Question

I use simple web services to access data from a database that resides on a server. I am using android api10, but when I run the code, I get the error java.lang.OutOfMemoryError .

My code is:

 package com.android.webservicesdemo; import java.util.ArrayList; import java.util.HashMap; import org.ksoap2.SoapEnvelope; import org.ksoap2.serialization.SoapObject; import org.ksoap2.serialization.SoapSerializationEnvelope; import org.ksoap2.transport.HttpTransportSE; import android.app.Activity; import android.os.Bundle; import android.view.View; import android.widget.Button; import android.widget.EditText; import android.widget.TextView; import android.widget.Toast; public class androidactivity extends Activity { /** Called when the activity is first created. */ private static String SOAP_ACTION1 = "http://tempuri.org/getAllDealsbyCategorySer"; private static String NAMESPACE = "http://tempuri.org/"; private static String METHOD_NAME1 = "getAllDealsbyCategorySer"; private static String URL = "http://dosha.dotnetgeekz.com/ServerServices.asmx?WSDL"; static final String KEY_DEAL = "deals"; // parent node static final String KEY_ID = "id"; static final String KEY_HEADLINE = "DealHeadline"; static final String KEY_CATEGORY = "DealCategory"; static final String KEY_PRICE = "BuyPrice"; ArrayList<HashMap<String, String>> menuItems = new ArrayList<HashMap<String, String>>(); Button btnFar, btnCel, btnClear; EditText txtFar, txtCel; TextView textView2; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.mains); btnFar = (Button) findViewById(R.id.btnFar); txtFar = (EditText) findViewById(R.id.txtFar); textView2 = (TextView) findViewById(R.id.textView2); btnFar.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { // Initialize soap request + add parameters SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME1); // Use this to add parameters request.addProperty("category", txtFar.getText().toString()); // Declare the version of the SOAP request SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); envelope.setOutputSoapObject(request); envelope.dotNet = true; try { HttpTransportSE androidHttpTransport = new HttpTransportSE(URL); // this is the actual part that will call the webservice androidHttpTransport.call(SOAP_ACTION1, envelope); // Get the SoapResult from the envelope body. SoapObject result = (SoapObject) envelope.bodyIn; if (result != null) { // Get the first property and change the label text textView2.setText(result.getProperty(0).toString()); } else { Toast.makeText(getApplicationContext(), "No Response",Toast.LENGTH_LONG).show(); } } catch (Exception e) { e.printStackTrace(); } } }); } } 

Mistake:

Answer 1

Is it possible your SOAP response is too large?

 08-31 11:36:06.660: E/AndroidRuntime(334): at org.ksoap2.serialization.SoapObject.toString(SoapObject.java:646) 08-31 11:36:06.660: E/AndroidRuntime(334): at com.android.webservicesdemo.androidactivity$1.onClick(androidactivity.java:84) 

Probably called line below

 textView2.setText(result.getProperty(0).toString()); 

The top line also mentions that the line length can be 2813318.
