App crash on device HTC M8 with OS Lollipop for web service call

Question

App crashing on Android Lollipop when calling web service using ksoap.

Please see error log

java.lang.NoSuchFieldError: No instance field headerOut of type [Lorg/kxml2/kdom/Element; in class Lorg/ksoap2/serialization/SoapSerializationEnvelope; or its superclasses (declaration of 'org.ksoap2.serialization.SoapSerializationEnvelope' appears in /system/framework/wifi-service.jar)

I have tested same app on Nexus 4 emulator of Android version 5.0 and is working fine.

I am using below code for calling webservice

mHttpTransportSE = new AndroidHttpTransport (url);
mHttpTransportSE.debug = true; // this is optional, use it if you don't
mHttpTransportSE.call(Configuration.COM_SOAP_ACTION_AUTHENTICATEUSER, envelope);
result = envelope.getResponse();

I have also change AndroidHttpTransport to HttpTransportSE but not sure for that.
Is this change resolve my problem?
Is any other solution for this problem?

Thank you in advance.

I solved it by changing ksoap2 package name to ksoap2clone. I don't know the solution is good but it's now working. Please share, if you find better solution.
