Migrating to the Android 4.x Library

This information helps you migrate from the 3.x or 2.x version of the Android library to version 4.x.

In the version 4.x library, the public methods are consolidated into one header. Also, all functionality is now accessible through class level methods, so you do not have to keep track of pointers, instances, or singletons.

The following sections walk you through the migration process:

Events, Props, and eVars

In version 4, you can no longer assign variables such as events, eVars, props, heirs, and lists 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 will not appear in reports until they are mapped using processing rules.

Tip: Values that you assigned directly to variables should be added to the data HashMap.

Remove Unused Properties

The new ADBMobileConfig.json 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" : false,
        "offlineEnabled" : true,
        "lifecycleTimeout" : 5,
        "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.

Moving the configuration file

  1. Move the value that is set for the variable in the first column to the variable in the second column.
  2. Remove the old configuration variable from your code.

Migrating from version 3.x

Move the value from the first column to the variable in the second column.

Remove, no longer used.

useBestPractices

all calls to churn measurement (getChurnInstance)

Remove, replaced by Lifecycle Metrics.

Update Track Calls and Tracking Variables

Instead of using the web-focused track and trackLink calls, the version 4 SDK uses the following methods:

  • trackState 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, such as "logons", "banner taps", "feed subscriptions", and so on that occur in your app and that you want to measure.

The contextData parameter for both of these methods is a HashMap<String, Object> that contains name-value pairs that are sent as context data.

Events, Props, eVars

In version 4, you can no longer assign variables such as events, eVars, props, heirs, and lists directly in your app. The SDK now 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 will not appear in reports until they are mapped using processing rules. For more information, see Processing Rules and Context Data.

Values that you were assigning directly to variables should be added to the data HashMap. This means that calls to setProp, setEvar, and assignments to persistent context data should be removed and the values be added to the data parameter.

AppSection/Server, GeoZip, Transaction ID, Campaign, and other standard variables

Data that you were setting on the measurement object, including the variables listed above, should be added to the data HashMap. The only data that is sent with a trackState or trackAction call is the payload in the data parameter.

Replace Tracking Calls

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

Migrating from version 3.x

  • trackAppState (trackState)
  • trackEvents (trackAction)
  • track (trackAction)
  • trackLinkURL (trackAction)

Migrating from version 2.x

  • track (trackState)
  • trackLink (trackAction)

Custom Visitor ID

Replace the visitorID variable with a call to setUserIdentifier.

Offline Tracking

Offline tracking is enabled in ADBMobileConfig.json, and all other offline configuration is done automatically.

In your code, remove calls to the following methods:

Version 3.x

  • setOnline
  • setOffline

Version 2.x

  • forceOffline
  • forceOnline

Products Variable
