Why show error Cannot serialize?

My webservice;
[WebMethod]
public int insertNhanVien(string[] arr)
{
SqlConnection con = new SqlConnection();
// con.ConnectionString = "Data Source=.\\SQLEXPRESS;Initial Catalog=Bai1;Integrated Security=True";
con.ConnectionString = "server=.\\SQLEXPRESS;database=QLNV;uid=sa;pwd=123456";
con.Open();
int n = 0;
for (int i = 0; i < arr.Length; i++)
{
string[] s = arr[i].ToString().Split(',');
SqlCommand cmd = new SqlCommand();
cmd.CommandText = "Insert Into MUser(Ten,Tuoi) values(" + s[0].Replace("'", "''") + "," + s[1] + ")";
cmd.CommandType = CommandType.Text;
cmd.Connection = con;
n = cmd.ExecuteNonQuery();
}
return n;
}
And code in android:
private boolean insertNhanVient() {
boolean result = false;
try {
String NAMESPACE ="http://tempuri.org/";
String METHOD_NAME ="insertNhanVien";
String URL ="http://localhost:10829/WebSite/Service.asmx";
String SOAP_ACTIONS = NAMESPACE + "/" + METHOD_NAME;
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
String [] arr =new String[3];
arr[0]="le,12";
arr[1]="hoang,33";
arr[2]="nhung,23";
request.addProperty("arr", arr);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
SoapEnvelope.VER11);
envelope.dotNet=true;
envelope.setOutputSoapObject(request);
HttpTransportSE androidhttpTranport = new HttpTransportSE(URL);
try {
androidhttpTranport.call(SOAP_ACTIONS, envelope);
} catch (IOException e3) {
result = false;
} catch (XmlPullParserException e3) {
result = false;
}
Object responseBody = null;
try {
responseBody = envelope.getResponse();
String t = responseBody.toString();
if (t.equals("1")) {
result = true;
}
} catch (SoapFault e2) {
result = false;
}
} catch (Exception e) {
result = false;
} finally {
}
return result;
}
Why show exception: java.lang.RuntimeException: Cannot serialize: [Ljava.lang.String;#4051d0a0 ?

you can't pass whole array.. so you have to use seprator ## in String ..and pass it service... and change on service respectivley.
String commasepratedString="";
for(int i=0;i<arr.length();i++)
{
if(i!=(arr.length-1))
{
commasepratedString=commasepratedString+arr[i]+"##";
}
else
{
commasepratedString=commasepratedString+arr[i];
}
}
request.addProperty("arr", commasepratedString);
and change service code like this way
[WebMethod]
public int insertNhanVien(string commasepratedString)
{
String arr[] = commasepratedString.Split('##');
SqlConnection con = new SqlConnection();
// con.ConnectionString = "Data Source=.\\SQLEXPRESS;InitialCatalog=Bai1; Integrated Security=True";
con.ConnectionString = "server=.\\SQLEXPRESS;database=QLNV;uid=sa;pwd=123456";
con.Open();
int n = 0;
for (int i = 0; i < arr.Length; i++)
{
string[] s = arr[i].ToString().Split(',');
SqlCommand cmd = new SqlCommand();
cmd.CommandText = "Insert Into MUser(Ten,Tuoi) values(" + s[0].Replace("'", "''") + "," + s[1] + ")";
cmd.CommandType = CommandType.Text;
cmd.Connection = con;
n = cmd.ExecuteNonQuery();
}
return n;
}

replace this line
request.addProperty("arr", arr);
with this
request.addProperty("arr", arr[0]);
you cannot pass whole array.you should pass one element of it.
Update
You can add multiple properties like
request.addProperty("prop1", arr[0]);
request.addProperty("prop2", arr[1]);
request.addProperty("prop3", arr[2]);

I need to arrange the barcharts properly in android

Right now i am creating a barchart in android using AChartEngine.After getting run of my application,at-first the emulator is showing like the first below image. But i need to show like the second below image how to do this?
And also i need to change the color for the background and also i wanna change the bar-charts colors,
How to do these things?
I have tried these codes, but not working
renderer.setApplyBackgroundColor(true);
renderer.setBackgroundColor(Color.GRAY);

Hi if you want to change background color for your chart just use these methods
mrenderer.setApplyBackgroundColor(true);
mrenderer.setBackgroundColor(Color.parseColor("#898989")); // here you have to give hexa decimal code
mrenderer.setMarginsColor(Color.parseColor("#898989")); // here you have to give hexa decimal code
If you want to change your bar color means just do like this
int[] colors = new int[] { Color.parseColor("#DAE1EB"), Color.parseColor("#406193")};
int color_length = colors.length;
for (int i = 0; i < color_length; i++)
{
SimpleSeriesRenderer r = new SimpleSeriesRenderer();
r.setColor(colors[i]);
r.setChartValuesSpacing(5);
mrenderer.addSeriesRenderer(r);
}
If you are creating multiple renderer means use different color for the dual bar. If you are creating single bar means give only one color. It will works.

Unable to pass multiple values from one screen to the multiple textview boxes of the another screen in android

I am trying to consume a web service from android by the method SOAP.
Here my problem is,actually i am getting two values from that web service namely "OrderNo" and "FreightRate" and i am trying to show these values in each Text-view boxes of the next screen but i am getting nothing on the text view boxes,
How to achieve this concept?Suggestions please..
NOTE :- I can able to show only any one values in the text view box of the another screen if i consume any one values like "orderNo" or "FreightRate". But unable to show two values simultaneously in separate text-view boxes of the another screen.

Thanks for your precious time!..

Maybe this is not your problem but, in your main activity you're trying to send both values with your intent but you are adding them using the same key. In your example you are always sending value y because you're overwriting the x value.
in.putExtra("gotonextpage",x);
in.putExtra("gotonextpage", y);
If I understand your problem correctly, you need to use two different keys for your values, when sending them with the intent, and extracting them.
in.putExtra("gotonextpageX",x);
in.putExtra("gotonextpageY", y);
x = extras.getString("gotonextpageX");
y = extras.getString("gotonextpageY");
Another way to do it is
x = getIntent().getStringExtra("gotonextpageX");
y = getIntent().getStringExtra("gotonextpageY");

I found what was wrong, thanks to someone.
1) I have used:
AndroidHttpTransport androidHttpTransport = new AndroidHttpTransport(SOAP_ADDRESS);
Instead it should be:
HttpTransportSE httptransport = new HttpTransportSE(SOAP_ADDRESS);
2) I have used:
PropertyInfo pi = new PropertyInfo();
pi.setName("fname");
pi.setValue(firstname);
pi.setType(int.class);
Request.addProperty(pi);
Instead it should be:
request.addProperty("fname", String.valueOf(firstname));
For the other text fields as well

You return the Method type as String & concert it Datatable to Json as String that is good way to do & easy
//Converting table to json
public String ConverTableToJson(DataTable dtDownloadJson)
{
string[] StrDc = new string[dtDownloadJson.Columns.Count];
string HeadStr = string.Empty;
if (dtDownloadJson.Rows.Count > 0)
{
for (int i = 0; i < dtDownloadJson.Columns.Count; i++)
{
StrDc[i] = dtDownloadJson.Columns[i].Caption;
HeadStr += "\"" + StrDc[i] + "\" : \"" + StrDc[i] + i.ToString() + "¾" + "\",";
}
if (HeadStr.Length > 0)
{
HeadStr = HeadStr.Substring(0, HeadStr.Length - 1);
StringBuilder Sb = new StringBuilder();
Sb.Append("{\"" + dtDownloadJson.TableName + "\" : [");
for (int i = 0; i < dtDownloadJson.Rows.Count; i++)
{
string TempStr = HeadStr;
Sb.Append("{");
for (int j = 0; j < dtDownloadJson.Columns.Count; j++)
{
TempStr = TempStr.Replace(dtDownloadJson.Columns[j] + j.ToString() + "¾", dtDownloadJson.Rows[i][j].ToString());
}
Sb.Append(TempStr + "},");
}
Sb = new StringBuilder(Sb.ToString().Substring(0, Sb.ToString().Length - 1));
Sb.Append("]}");
return Sb.ToString();
}else

}

The error you are getting aint an error at all. At least, thats the behavious I saw at my own application using a setup that was quite like the one you have there. Have you tried casting the response to a SoapObject? You can then call the .getPropertyCount() method on that SoapObject to start looping trough the content of the response. Quick example:
//Create a Transport object makes the webservice call
HttpTransportSE httpTrans = new HttpTransportSE(URL);
httpTrans.call(SOAP_ACTION, env);
//Cast the object to SoapObject
SoapObject storages = (SoapObject)env.getResponse();
//Loop trough the result
for(int i = 0; i < storages.getPropertyCount(); i++) {
//Get a SoapObject for each storage
SoapObject storage = (SoapObject)storages.getProperty(i);
}
Seeing the response you got, you might have to dig a few levels deep to get the data you need tho. Either 6 or 7 levels deep. If it is an option, I would change the response you get from the webservice so that it is easier to parse.
