Context context = getApplicationContext(); CharSequence contentTitle = "Notification Details..."; CharSequence contentText = "Browse Android Official Site by clicking me"; Intent notifyIntent = new Intent(Intent.ACTION_VIEW, 	Uri.parse("")); PendingIntent pintent = PendingIntent.getActivity(SimpleNotification.this, 0, notifyIntent, 	Intent.FLAG_ACTIVITY_NEW_TASK); notifyDetails.setLatestEventInfo 	(context, contentTitle, contentText, pintent); 96 1.4 NotificationManager Step 4: Now the stage is set. Notify. mNotificationManager.notify 	(SIMPLE_NOTFICATION_ID, notifyDetails); mNotificationManager.cancel 	(SIMPLE_NOTFICATION_ID); 97 1.4 NotificationManager Example : Show notification 98 1.4 NotificationManager Example : cont 99 1.4 NotificationManager Example : cont 100 5. Webservice .Net 5.1 Introduction Webservice 5.2 How to create .Net Webservice 5.3 How to config IIS 5.4 KSOAP API 5.5 Android to .Net Webservice 101 5.1 Introduction Webservice Support machine-to-machine collaboration. They can be described, published, located, and invoked over a data network. Web services are used to implement the notion of a service-oriented architecture (SOA). SOA applications are independent of specific programming languages or operating systems. Web services rely on existing transport technologies, such as HTTP, and XML, for invoking the implementation. 102 5.1 Introduction Webservice The interface describing the format of services can be done using the Web Services Description Language (WSDL). According to W3C there are two major types of web services REST-compliant which use XML to represent its Web resources, and offers a "stateless" set of operations; and Arbitrary solutions, in which the service may expose a heterogeneous set of operations. 103 5.1 Introduction Webservice Two widely used architectures supporting Web services are Representational State Transfer (REST) Closely tie to the HTTP protocol by associating its operation to the common GET, POST, PUT, DELETE for HTTP. Remote Procedure Call (RPC). Web services are directly implemented as language-specific functions or method calls. In this category we find 1.Object Management Group's (OMG) Common Object Request Broker Architecture (CORBA), 2.Microsoft's Distributed Component Object Model (DCOM) and 3.Sun Microsystems's Java/Remote Method Invocation (RMI). 104 5.1 Introduction Webservice IIS webserver (RPC discrete function oriented approach) 105 5.1 Introduction Webservice Services are passive server-side pieces of code waiting for incoming messages to do some work. Clients initiate the interaction by sending a message to server-services requesting action. Services expose one or more endpoints where messages can be sent. Each endpoint consists of address (where to send messages) binding (how to send messages ) contract (what messages contain) Clients can use WSDL to know this information before accessing a service. 106 5.1 Introduction Webservice Windows Communication Foundation (WCF) uses the information found in the service contract to perform dispatching and serialization. Dispatching is the process of deciding which method to call for an incoming SOAP message. Serialization is the process of mapping between the data found in a SOAP message and the corresponding .NET objects used in the method 107 5.2 How to create .Net Webservice 1.
