Offline-Mode

For Android and iOS version, springKantar Media Audiences-lib has a feature the so-called "offlineMode". This mode can be switched on and off by using public API: setOfflineMode (boolean offlineMode)KMA_SpringStreams.offlineMode.

If the lib is configured to offlineMode,

...

KMA_SpringStreams library will hold all requests in a local buffer and send them when the device goes back online.

...

KMA_SpringStreams lib checks the

...

internet connection regularly by using the

...

iOS Timer and

...

send the data as soon as possible.

Please notice:

Old requests will be dropped if too many requests pump into local buffer for the limitation in buffer size.
The default buffer size is 500. (Note: in case of streaming requests only the last request of a singular streaming sequence is stored, in other words it allows for 500 views to be stored)
The data will be stored in a local file, so the lib will not lose the requests even if the application terminates
the springKantar Media Audiences-lib tries to send the requests in a fixed rate, 10 seconds by default, and sends them if device is online again

iOS

Identifiers on iOS

...

How the library acts when offline-mode is enabled:

The device will keep trying to empty the ring buffer by attempting to send requests to the measuring system.
When there is a connection, the requests seamlessly pass through the ring buffer.
When there is no connection, the requests will be retained indefinitely.

For more information, check the chapter about offline-mode below.

iOS Identifiers

	Device ID (did)	Advertising ID (ai)	Mac ID (mid)	ID_For_Vendor (ifv)
iOS4	---	---		---
iOS5	---	---		---
iOS6	---
iOS7	---		---
iOS8	---		---
iOS9	—		—

Considering that the Apple private policy is changing all the time, Spring Kantar Media Audiences libs have to adapt different UDIDs for identifying the end user's devices.

...

Note
Please attention: Apple will reject all the applications which retrieve Advertising ID (ai) but with no advertising content provided. So Advertising-Framework is linked as optional in Spring Kantar Media Audiences lib, If the Advertising ID should be used as udid, please import Advertising-Framework into your projects.

Migration to iOS9

URL Scheme White-listing

Starting on iOS 9iOS9, iOS apps will have to declare what URL schemes they would like to be able to check for and open in the configuration files (plist file) of the app as it is submitted to Apple.
So if your application is combining with a specific "Panel App" (e.g. Virtualmeter App), please register the URL scheme in your application, the syntax is as following:

Code Block
<key>LSApplicationQueriesSchemes</key> <array> <string>XX.XXX<string>..ipm</string> //please change .** to the parameters given in your <string>XXXXXPanelApp</string> </array>

library delivery 
         <string>*****PanelApp</string> //please change ***** to the parameters given in your library delivery  
     </array>

App Transport Security (ATS)

Starting from iOS 9.0, App Transport Security (ATS) enforces best practices in the secure connections between an app and its back end.
Migrating from "http" to "https" has to be planed for the more secure communication.
However for this moment, if you decide to enable ATS, a temporary solution can be adapted by adding an exception for Kantar Media Audiences measurement box:

Code Block

<key>NSAppTransportSecurity</key> 
 <dict> 
         <key>NSAllowsArbitraryLoads</key> 
         <false/> 
         <key>NSExceptionDomains</key> 
         <dict> 
             <key>XXXXXXXXX</key> 
<key>*****</key> //please change ***** to the parameters given in your library delivery 
             <dict> 
                 <key>NSIncludesSubdomains</key> 
                 <true/> 
                 <key>NSTemporaryExceptionAllowsInsecureHTTPLoads</key> 
                 <true/> 
                 <key>NSExceptionRequiresForwardSecrecy</key> 
                 <false/> 
             </dict> 
         </dict> 
     </dict>

Note
if ATS is not enabled in your application, as NSAllowsArbitraryLoads = true, then you don't need to modify anything.

Bitcode

BitCode

Bitcode is a new feature on iOS 9, an intermediate representation of a compiled program. Now you have the new Kantar Media Audiences lib with bitcode Bitcode enabled , for your application you have the chance to enable or disable the bitcode Bitcode service.

Android Identifier

Google Advertising ID

Beginning with Spring Kantar Media Audiences lib 1.6.0, GoogleAdvertisingID is adapted to identify the android devices.
In order to achieve this, please import google-play-services_lib to your application.
Follow the tutorial detailed info: http://developer.android.com/google/play-services/setup.html

Install the Google Play Services SDK.
Import the project into your application.

Don't forget to add following items into your project AndroidManifest.xml file:

Code Block
<meta-data

 android:name="com.google.android.gms.version"

 android:value="@integer/google_play_services_version"

/>
