ksoap2 android web services complextype byte[]

ksoap2 android web services complextype byte[] - java

I have a web service that receives an object of complexType Pic,
Pic.java
public class Pic implements KvmSerializable{
private double latitude;
private double longitude;
private long time;
private double accuracy;
private String name;
private byte[] imageInByte;
public byte[] getImageInByte() {
return imageInByte;
}
public void setImageInByte(byte[] imageInByte) {
this.imageInByte = imageInByte;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public double getLatitude() {
return latitude;
}
public void setLatitude(double latitude) {
this.latitude = latitude;
}
public double getLongitude() {
return longitude;
}
public void setLongitude(double longitude) {
this.longitude = longitude;
}
public double getAccuracy() {
return accuracy;
}
public void setAccuracy(double accuracy) {
this.accuracy = accuracy;
}
public long getTime() {
return time;
}
public void setTime(long time) {
this.time = time;
}
#Override
public Object getProperty(int arg0) {
switch(arg0){
case 0:
return latitude;
case 1:
return longitude;
case 2:
return time;
case 3:
return accuracy;
case 4:
return name;
case 5:
return imageInByte;
}
return null;
}
#Override
public int getPropertyCount() {
return 6;
}
#Override
public void getPropertyInfo(int arg0, Hashtable arg1, PropertyInfo arg2) {
switch(arg0){
case 0:
arg2.type = PropertyInfo.STRING_CLASS;
arg2.name = "latitude";
break;
case 1:
arg2.type = PropertyInfo.STRING_CLASS;
arg2.name = "longitude";
break;
case 2:
arg2.type = PropertyInfo.LONG_CLASS;
arg2.name = "time";
break;
case 3:
arg2.type = Double.class;
arg2.name = "accuracy";
break;
case 4:
arg2.type = PropertyInfo.STRING_CLASS;
arg2.name = "name";
break;
case 5:
arg2.type = MarshalBase64.BYTE_ARRAY_CLASS;
arg2.name = "imageInBytes";
default:
break;
}
}
#Override
public void setProperty(int arg0, Object arg1) {
// TODO Auto-generated method stub
switch(arg0){
case 0:
latitude = Double.parseDouble(arg1.toString());
break;
case 1:
longitude = Double.parseDouble(arg1.toString());
break;
case 2:
time = Long.parseLong(arg1.toString());
break;
case 3:
accuracy = Double.parseDouble(arg1.toString());
break;
case 4:
name = arg1.toString();
break;
case 5:
imageInByte = Base64.decode(arg1.toString(), Base64.DEFAULT);
break;
default:
break;
}
}
}
I send it to a webservice by registering in the envelope doubles and marshalBase64. So far everything runs smoothly although in the web service once i get the object the method picture.imageInByte() returns null. I am not sure of what is happening because i could pass just a byte[] variable like this and write the file to disk. But i only passed a byte[] not a complex object with a byte[] inside.
What is the problem?

The way i solved was by altering the web service to receive 2 parameters instead of one.
like this:
public void receivePicture(Pic picture, byte[] image){
}
where picture is the information i need about the image itself and image is the actual image file.
I know this is somehow a hack and not exactly the good solution i was looking for but it works.

Firebase : Data not stored in the correct format

Please understand my scenario before marking it as a duplicate. I've searched for a while but didn't find the answer on the site.
I am sending data to Firebase through a fragment using setValue(Modelclass object) but the data is not stored in the format as it was supposed to be.

Data should be stored as in model class as:
UID
firstName :
lastName :
regNo :
gender :
campus :
dept :
program :
semester :
routeTitle :
routeId:
Rather, it is stored as:

It doesn't matter the order of the fields in your "StudentModel" class, because when you are adding a new instance of the class to the Firebase Realtime Database, all the fields are automatically ordered alphabetically. Besides that, the order of calling the setters on your "studentModel" object, doesn't matter too. The Firebase Console, always orders the fields alphabetically. See, the field starts with the letter "c", the second one with "d", and so on till the end, where the last field starts with "s". Unfortunately, this order cannot be changed in the Firebase Console. If you want, you can change the order in your class to be alphabetical and match the order in the database, that's fine, but it doesn't make any sense in my opinion.

Android calculator app decimal results

I'm Mikamocha, and I just started programming Android apps. I have problems in my first calculator app (the results). What I mean is so that 2+2 will be 4 instead of 4.0, 5-2 will be 3 instead of 3.0, etc.
package com.yeshua.mikamocha.myxcalculator;

Thanks.

You should use NumberFormat.
For example:
public static void main(String[] args) {
System.out.println(format(14.0184849945)); // prints '14.01'
System.out.println(format(13)); // prints '13'
System.out.println(format(3.5)); // prints '3.5'
System.out.println(format(3.138136)); // prints '3.13'
}
public static String format(Number n) {
NumberFormat format = DecimalFormat.getInstance();
format.setRoundingMode(RoundingMode.FLOOR);
format.setMinimumFractionDigits(0);
format.setMaximumFractionDigits(2);
return format.format(n);
}

you are using float datatype for result instead of use int type and parse operation value in int.
result = (int)(NumAf + NumberBf);

For Ref. DecimalFormat
Change as follows as you are using float as result you are getting decimal so use int,
private int result=0;
//and
result =(int) (NumAf + NumberBf);
OR
float one= 2.0;
float two= 2.5;
//DecimalFormat format = new DecimalFormat();
//format.setDecimalSeparatorAlwaysShown(false);
DecimalFormat format=new DecimalFormat("#,###.#");
System.out.println( format.format(one) );//prints 2
System.out.println( format.format(two) );//prints 2.5

Error Parsing XML response attributes with ksoap2 returns ClassCastException

I'm trying to figure out how to cast the response of the consume of a webservice, when casting the response envelope.bodyIn to my extended class object "BiometricConfigurationResponse" i'm getting this error:
java.lang.ClassCastException: org.ksoap2.serialization.SoapObject cannot be cast to org.tempuri.BiometricConfigurationResponse
The service is responding well and if i not cast it i get the dump right.
Any ideas?
This is what i'm doing:
BiometricConfigurationResponse response= null;
SoapObject obj = new SoapObject (wsNameSpace, methodName);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.implicitTypes = true;
envelope.dotNet = true;
envelope.setOutputSoapObject(obj);
envelope.addMapping(wsNameSpace, "BiometricConfigurationResponse", new BiometricConfigurationResponse().getClass());
HttpTransportSE androidHttpTransport = new HttpTransportSE(wsURL);
androidHttpTransport.debug = true;
try {
String soapAction=wsNameSpace + methodName;
androidHttpTransport.call(soapAction, envelope);
System.out.println(androidHttpTransport.requestDump);
response = (BiometricConfigurationResponse)envelope.bodyIn;
}
catch (Exception e) {
e.printStackTrace();
}
And this is my custom class

After several days of research i understood that WSDL autogenerated code parse Properties but not Atrributes. So what i did was this:
First i generate the stub code from my WSDL in this website: http://www.wsdl2code.com/pages/home.aspx
My webservice name is "nutriment" son when you call it in MainActivity you have to do this:
nutriment nws= new nutriment();
BiometricConfigurationResponse respuesta = nws.GetBiometricConfiguration();
Log.i(TAG, String.valueOf(respuesta.coderAlgorithm));
Log.i(TAG, String.valueOf(respuesta.templateFormat));
But it responses 0 in all cases because the WDSL stub files are parsing PROPERTIES NOT ATRIBUTES, so when you open the serialization generated file you'll got something like this:
import org.ksoap2.serialization.KvmSerializable;
import org.ksoap2.serialization.PropertyInfo;
import java.util.Hashtable;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapPrimitive;
public class BiometricConfigurationResponse implements KvmSerializable {
public int coderAlgorithm;
public int templateFormat;
public BiometricConfigurationResponse(){}
public BiometricConfigurationResponse(SoapObject soapObject)
{
if (soapObject == null)
return;
if (soapObject.hasProperty("coderAlgorithm"))
{
Object obj = soapObject.getProperty("coderAlgorithm");
if (obj != null && obj.getClass().equals(SoapObject.class)){
SoapPrimitive j =(SoapPrimitive) obj;
coderAlgorithm = Integer.parseInt(j.toString());
}
else if (obj!= null && obj instanceof Number){
coderAlgorithm = (Integer) obj;
}
}
if (soapObject.hasProperty("templateFormat"))
{
Object obj = soapObject.getProperty("templateFormat");
if (obj != null && obj.getClass().equals(SoapPrimitive.class)){
SoapPrimitive j =(SoapPrimitive) obj;
templateFormat = Integer.parseInt(j.toString());
}else if (obj!= null && obj instanceof Number){
templateFormat = (Integer) obj;
}
}
}
#Override
public Object getProperty(int arg0) {
switch(arg0){
case 0:
return coderAlgorithm;
case 1:
return templateFormat;
}
return null;
}
#Override
public int getPropertyCount() {
return 15;
}
#Override
public void getPropertyInfo(int index, #SuppressWarnings("rawtypes") Hashtable arg1, PropertyInfo info) {
switch(index){
case 0:
info.type = PropertyInfo.INTEGER_CLASS;
info.name = "coderAlgorithm";
break;
case 1:
info.type = PropertyInfo.INTEGER_CLASS;
info.name = "templateFormat";
break;
}
#Override
public void setProperty(int arg0, Object arg1) {
}
#Override
public String getInnerText() {
// TODO Auto-generated method stub
return null;
}
#Override
public void setInnerText(String arg0) {
// TODO Auto-generated method stub
}
}
The trick is to modify the parsing so instead of get the properties(e.g.):
if (soapObject.hasProperty("coderAlgorithm")){
Object obj = soapObject.getProperty("coderAlgorithm");
if (obj != null && obj.getClass().equals(SoapObject.class)){
SoapPrimitive j =(SoapPrimitive) obj;
coderAlgorithm = Integer.parseInt(j.toString());
}
else if (obj!= null && obj instanceof Number){
coderAlgorithm = (Integer) obj;
}
}
Get the ATTRIBUTES (e.g.):
if (soapObject.hasAttribute("coderAlgorithm")) {
Object obj = soapObject.getAttribute("coderAlgorithm");
if (obj != null && obj.getClass().equals(SoapObject.class)){
SoapPrimitive j =(SoapPrimitive) obj;
coderAlgorithm = Integer.parseInt(j.toString());
}
else if (obj!= null && obj instanceof Number){
coderAlgorithm = (Integer) obj;
}
else if (obj!= null && obj instanceof String){
coderAlgorithm = Integer.parseInt(obj.toString());
}
}

The variables such as uaero and uagri are boolean fields of objects. I have a quite a few objects in this class. The variables such as ListOfMajors.aerospace and ListOfMajors.agricultural are boolean values from another class which are set to true if a checkbox is clicked. All of these pairs of variables correspond with each other and would like the variable match set to true if both of the other variables are true. As of right now, the code doesn't seem to working as match doesn't appear to be changing to true. What should I do to get this to work?

Your cases are probably not doing what you think .. since there is no break a case position 0 will set all of the variables to true (or false)
switch(position){
case 0: aerospace = true; break;
case 1: agricultural = true;break;
case 2: biomed = true;break;
case 3: chem = true;break;
case 4: civil = true;break;
case 5: computer = true;break;
case 6: electrical = true;break;
case 7: physics = true;break;
case 8: environment = true;break;
case 9: industrial = true;break;
case 10: materials = true;break;
case 11: mechanical = true; break;
}

Can't make instance from java class

I write code for MSN application , and this application connection with server ASP.NET
this code run perfectly in my computer , but when I run this code in other computer
it is giving me runtime error in this line
new SigninPerson(s1,s2);

}
it is make new for SigninPerson and don't give me run time
I am trying to found the problem long time but I can't find any wrong
please , anyone can help me
because I must send my application in the morning

You should change this line:
SigninPerson SIPerson = null;
new SigninPerson(s1,s2);
to:
SigninPerson SIPerson = new SigninPerson(s1,s2);

It'll give you a NullPointerException as you declared a reference for the SigninPerson, but you never assigned it to a new object of this class as #SOfanatic recommended for you ( +1 for him).
SigninPerson SIPerson = null;// << here assign SIPerson to new SigninPerson
//....
p.setValue(SIPerson);
p.setType(SIPerson.getClass());
