This section describes how to migrate from the 3.x version of the Windows mobile SDK to the Universal Windows Platform 4.x SDK for Experience Cloud Solutions.

With the move to version 4.x, all functionality is now accessible through static methods. You no longer need to keep track of your own objects.

The following sections walk you through migrating from version 3.x to version 4.x.

You probably noticed a new ADBMobileConfig.json file included with your download. This file contains application-specific, global settings, and replaces most of the configuration variables that were used in previous versions.

Here is an example of an ADBMobileConfig.json file:

{ 
    "version" : "1.0", 
    "analytics" : { 
        "rsids" : "coolApp", 
        "server" : "my.CoolApp.com", 
        "charset" : "UTF-8", 
        "ssl" : true, 
        "offlineEnabled" : true, 
        "lifecycleTimeout" : 300, 
        "privacyDefault" : "optedin", 
        "poi" : [ 
                    ["san francisco",37.757144,-122.44812,7000], 
                    ["santa cruz",36.972935,-122.01725,600] 
                ] 
    }, 
 "target" : { 
  "clientCode" : "myTargetClientCode", 
  "timeout" : 5 
 }, 
 "audienceManager" : { 
  "server" : "myServer.demdex.com" 
 } 
}

The following tables list the configuration variables that you need to move to the configuration file. Move the value set for the variable in the first column to the variable in the second column, and then remove the old configuration variable from your code.

The following table provides a list of variables in the 3.x SDKs and the new name in the 4.x SDKs:

Instead of using the web-focused Track and TrackLink calls, the version 4 SDK uses two methods that make a little more sense in the mobile world:

• TrackState States are the views that are available in your app, such as "home dashboard", "app settings", "cart", and so on. These states are similar to pages on a website, and trackState calls increment page views.

• TrackAction Actions are the things that happen in your app that you want to measure, such as "logons", "banner taps", "feed subscriptions", and other metrics. These calls do not increment page views.

The contextData parameter for both of these methods contains name-value pairs that are sent as context data.

If you've looked at the SDK methods, you are probably wondering where to set events, eVars, props, heirs, and lists. In version 4, you can no longer assign those types of variables directly in your app. Instead, the SDK uses context data and processing rules to map your app data to Analytics variables for reporting.

Processing rules provide the following advantages:

• You can change your data mapping without submitting an update to the App Store.
• You can use meaningful names for data instead of setting variables that are specific to a report suite.
• There is little impact to sending in extra data. These values won’t appear in reports until they are mapped using processing rules.

For more information, see the Processing rules section in Analytics overview.

Any values that you were assigning directly to variables should be added to context data instead. This means that calls to SetProp, SetEvar, and assignments to persistent context data should all be removed and the values added to context data.

Any other data that you were setting on the measurement object, including the variables listed above, should be added to context data instead. That is, the only data sent in with a TrackState or TrackAction call is the payload in the data parameter.

Replace tracking calls

Throughout your code, replace the following methods with a call to trackState or trackAction:

Migrating from 3.x:

• TrackAppState (TrackState)
• TrackEvents (TrackAction)
• Track (TrackAction)
• TrackLinkURL (TrackAction)

Replace the visitorID variable with a call to setUserIdentifier.

Offline tracking is enabled in the ADBMobileConfig.json file. All other offline configuration is done automatically.

Throughout your code, remove calls to the following methods:

Migrating from 3.x:

• SetOnline
• SetOffline

Since the products variable is not available in processing rules, you can use the following syntax to set products:

// create a processing rule to set the corresponding product event. 
// for example, set the Product Views event when context data a.action = "product view" 
var cdata = new Windows.Foundation.Collections.PropertySet(); 
cdata["&&products"] = ";Cool Shoe"; 
ADB.Analytics.trackAction("product view", cdata);

The value of "&&products" (in this example, the value is ";Cool Shoe") should follow the products string syntax for the type of event that you are tracking.
