It all worked when I tried it, but I did have some issues with the installation. It sounds as though you may have some component(s) missing from your setup. I have to admit that setting up both Android Studio and Eclipse are somewhat less than straightforward, and you have to make some guesses along the way. Have you installed all the correct SDK components as listed in the article?
|
|
|
|
|
I believe I have.
This may be asking a lot, but could you list the steps with links that you installed/downloaded/configured, so I have a baseline and do not have any room for error with guesses?
|
|
|
|
|
Sorry, no, I did not make a note of them. All you can do is try re-installing and carefully following the steps in the tutorial. If it helps there are a number of other tutorials in the same section which might help to clarify things.

Thanks anyway. This is too difficult to do, just to write code (which should be the more difficult part) so I'm not going to waste anymore time on this. I'll stick to Visual Studio and C#, I can't imagine anyone going through this frustration to write Android applications.
|
|
|
|
|
Well you are half right. Yes it is a pain when something goes wrong during installation/setup, but Android is not the only system to have issues like this: have you ever tried to setup SQL server? And, once you have it all set up the actual programming side is not such a struggle, although there is (obviously) a lot to learn.

**********************************************
I. lucky Cases if theif is innocent & swithed on the mobile & start using.
1.Case when internet is on.
I found mobile theft has become more serious problem now a days.
Tracing the lost/stolen devices with already connected with internet & gmail account is easier now.
2.Case when internet is off
Lucky if installed the mobile tracking apps which can be operated with SMS
**********************************************
II. Un-lucky if theif is smart [using the original IMEI]
He will surely switch off the phone, remove the SIM & google to Hard reset the device which swipe all the gmail accounts, fb accounts ,data etc
means the tracing apps already installed or going to be installed using the synced gmails wont work.
In this case mobile tracking can only done by Cyber Police.
But i found in India like country where police will have no interest in tracing the device.
So what an individual do even his device is so smarter but still a it does't recognise his owner.
[i am one of the suffered with lost]
Suggestion:
in this case google/OS providers should add a feature as described below:
1. A google/ facebook/ Iphone account should be synced with IMEI.
so that even if Hard reset the device,its IMEI will not be lost & his all accounts should not be erased.
2. If really owner intention to sell the device to other person,
then device should ask online OTP password sent to his any of the synced device accounts to erase all of his synced accounts from that device.
3. Every SIM change info should be sent to any synced accounts [no disabled option for this feature].
4. Every SIM change info should be sent to if any alternate phone number.
**********************************************
III. Un-lucky if theif is very/too smart [erasing the original IMEI/Flashing the device which replaces the original IMEI]
1. Erasing the original IMEI:
a. I think in this case IMEI change history should be maintained from the device side.
b. Every change should be reported to synced device accounts/ cell alternate numbers.
2. Flashing the device which replaces the original IMEI
a. for flashing device should ask the password otherwise it should not flash.
b. in case if forgetten & needed the password,then user should switch on the device & ask for flash pin from device to be send to any of the synced device account or SMS to his cell number.
**********************************************
Please please please, please let me know if more good suggesions can be added. & implemented.
I strongly suggest both Google or phone manufacturing company should implement this feature

I want to login the soap based webservice from android application but the code is not working i tried too much :

private static String NAMESPACE = "http://tempuri.org/";
//Webservice URL - WSDL File location
private static String URL = "http://www.domain.co.in/Service.asmx";
//SOAP Action URI again Namespace + Web method name
private static String SOAP_ACTION = "http://www.tempuri.org/GetUserDetails";
public static boolean invokeLoginWS(String username,String passWD, String webMethName) {
boolean loginStatus = false;
// Create request
SoapObject request = new SoapObject(NAMESPACE, webMethName);
// Property which holds input parameters
PropertyInfo userName = new PropertyInfo();
PropertyInfo password = new PropertyInfo();
// Set Username
userName.setName("username");
// Set Value
userName.setValue(username);
// Set dataType
userName.setType(String.class);
// Add the property to request object
request.addProperty(userName);
//Set Password
password.setName("password");
//Set dataType

//Add the property to request object
request.addProperty(password);
// Create envelope
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
SoapEnvelope.VER11);
// Set output SOAP object
envelope.setOutputSoapObject(request);
// Create HTTP call object
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
try {
// Invoke web service
androidHttpTransport.call(SOAP_ACTION+webMethName, envelope);
// Get the response
SoapPrimitive response = (SoapPrimitive) envelope.getResponse();
// Assign it to boolean variable variable
loginStatus = Boolean.parseBoolean(response.toString());
} catch (Exception e) {
//Assign Error Status true in static variable 'errored'
CheckDNLoginActivity.errored = true;
e.printStackTrace();
}
//Return booleam to calling object
return loginStatus;
}
}
Please have look at the code and tell me if there is any problem?

You need to use your debugger to collect more information and explain exactly what not working means.

Thanks very much for your reply.it really helped me out.especially the tutorial from http://programmerguru.com/
i am very grateful for the help provided

You see how easy it is to find information through Google.
|
|
|
|
|
yeah it is actually easy but getting the right tutorial and trying to get it work is also another problem.Others post tutorials which are combersome for beginners like us
|
|
|
|
|
Well you have to do what the rest of us do, and search through the ones you find until you find one that suits your level of skill and knowledge. You can't expect other people to make that determination on your behalf.
