I am newbie to android development. I am using android studio for developing an app. I know there are lot and lot of questions related to it, i looked into them but my problem still exists. Below are the solutions in which i have looked into.
I clearly looked into them and match with my problem. But still i am unable to solve my issue.
The app is simple that will have a editText a button and a textView. User should enter id in editText and when the button is tapped then the corresponding name should be shown. The button will use a webservice.
For this i created some tables in SQL. And created a webservice in dotnet.
Below is my web service
[WebMethod]
public string findContact(string eid)
{
return getContact(eid);
}
public string getContact(string eid)
{
SqlConnection conn;
conn = ConnectionManager.GetConnection();
conn.Open();
SqlCommand newCmd = conn.CreateCommand();
newCmd.CommandType = CommandType.Text;
newCmd.CommandText = "Select Name from Users where Id=" + eid + "";
SqlDataReader sdr = newCmd.ExecuteReader();
String address = null;
if(sdr.Read())
{
address = sdr.GetValue(0).ToString();
}
conn.Close();
return address;
}
Below is my manifest file
<uses-permission android:name="android.permission.INTERNET"/>
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
Below is my java code
public class MainActivity extends AppCompatActivity {
/** Called when the activity is first created. */
private static final String SOAP_ACTION = "http://tempuri.org/findContact";
private static final String METHOD_NAME = "findContact";// webservice web method name
private static final String NAMESPACE = "http://tempuri.org/";
private static final String URL = "http://192.168.100.9:9698/WebService.asmx";
TextView textView;
Button button;
EditText editText;
String ID;
public static final String LOG_TAG = MainActivity.class.getSimpleName();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
textView = (TextView)findViewById(R.id.webServ);
button = (Button)findViewById(R.id.btnSubmit);
if (android.os.Build.VERSION.SDK_INT > 9) {
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
}
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
SoapObject request = new SoapObject(NAMESPACE,METHOD_NAME);
PropertyInfo propertyInfo = new PropertyInfo();
propertyInfo.type = PropertyInfo.STRING_CLASS;
propertyInfo.name = "eid";
editText = (EditText)findViewById(R.id.enterID);
ID = editText.getText().toString();
request.addProperty(propertyInfo,ID);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.dotNet = true;
envelope.setOutputSoapObject(request);
HttpTransportSE httpTransportSE = new HttpTransportSE(URL);
httpTransportSE.debug = true;
try
{
httpTransportSE.call(SOAP_ACTION,envelope);
Object response = envelope.getResponse();
textView.setText(response.toString());
} catch (XmlPullParserException e) {
textView.setText(e.toString() + " Or enter ID is not valid!");
e.printStackTrace();
} catch (IOException e) {
textView.setText(e.toString() + " IOException Or enter ID is not valid!");
e.printStackTrace();
}
String res = (httpTransportSE.responseDump).toString();
Log.v(LOG_TAG, res);
}
});
}}
When i click on the button i am getting the bellow error.

It hits at the line httpTransportSE.call(SOAP_ACTION,envelope);
I am testing it on the emulator, below is the screen shot of my emulator
I have also checked my Webservice running in web browser, it's working fine. But it's not on the emulator.
Any help would be highly appreciated.
