DCR Video Android SDK

Engineering Portal / Digital / DCR & DTVR / DCR Video Android SDK

Overview

The Nielsen SDK is one of multiple framework SDKs that Nielsen provides to enable measuring linear (live) and on-demand TV viewing using TVs, mobile devices, etc. The App SDK is the framework for mobile application developers to integrate Nielsen Measurement into their media player applications. It supports a variety of Nielsen Measurement Products like Digital in TV Ratings, Digital Content Ratings (DCR & DTVR), Digital Ad Ratings (DAR), and Digital Audio. Nielsen SDKs are also equipped to measure static content and can track key life cycle events of an application like:

Application launch events and how long app was running
Time of viewing a sub section / page in the application.

Prerequisites

To start using the App SDK, the following details are required:

App ID (appid): Unique ID assigned to the player/site and configured by product.
sfcode: Unique identifier for the environment that the SDK should point to.
Nielsen SDK: The Nielsen SDK package contains a variety of sample players for your reference.

If you do not have any of these prerequisites or if you have any questions, please contact our SDK sales support team. Refer to Digital Measurement Onboarding guide for information on how to get a Nielsen App SDK and appid.

Implementation

This guide covers implementation steps for Android Studio utilizing the Standard Nielsen SDK for DCR.

How to obtain the NielsenAppApi

The Nielsen AppSDK can either be downloaded directly or can be integrated directly within an application through the use of a CocoaPod or Gradle.

Setting up your Development Environment

Configuring Android Development Environment

The Nielsen App SDK (located in the Downloads section of the website) class is the primary application interface to the Nielsen App SDK on Android.
The Nielsen App SDK class is defined as the only public class belonging to the com.nielsen.app.sdk package.

Nielsen App SDK is compatible with Android OS versions 2.3+. Clients can control / configure the protocol to be used – HTTPS or HTTP to suit their needs.

The requirement for the Java AppSdk.jar library and the libAppSdk.so native library will depend on the type of host application that will make use of them.

For Video player applications
- The Android OS hosting the App SDK should use a media player supporting HLS streaming (Android 3.0 and later will support it natively).
- If the player application uses a 3rd party media player implementing its own HLS, then the minimum Android version will be limited to version 2.3, since the SDK depends on Google Play support to work properly.
For Audio player applications
- The Android OS hosting the App SDK should be at version 2.3 and later since the SDK depends on the Google Play support to work properly.

Once SDK is downloaded ensure to unzip the Nielsen SDK and copy the AppSdk.jar in your app (Android Studio) libs folder, then right click the AppSdk.jar and select Add As Library. Ensure the AppSdk.jar file is added in 'build.grade (App Level) file.

App SDK 1.2 provides support for x86, mips, and armeabi-7a architecture.

Google Play Services

Add the Google Play Services in the project, Steps: Android Studio -> File -> Project Structure ->(In module selection) select App -> Dependencies (tab) -> Click "+" button and select "com.google.android.gms:play-services". Ensure it is added in build.gradle (App level) file

Manifest File

Add the following permissions on the project’s AndroidManifest.xml file.

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.INTERNET"/>

For more details to handle runtime permissions in Android versions, please visit [1].

In AndroidManifest.xml under <application> node add the following metadata

<meta-data 
android:name="com.google.android.gms.version" 
android:value="@integer/google_play_services_version"/>

App SDK checks to see if there is a Google service available and updated.
If not available or updated, App SDK will not use this service when executing its functions and will make reference to missing imports and the app will not be compiled.

Library

Nielsen App SDK uses the following packages/classes from the Google Play service.

google-play-services_lib

Classes/package

com.google.android.gms.ads.identifier.AdvertisingIdClient;
com.google.android.gms.ads.identifier.AdvertisingIdClient.Info;
com.google.android.gms.common.ConnectionResult;
com.google.android.gms.common.GooglePlayServicesUtil;
com.google.android.gms.common.GooglePlayServicesRepairableException;
com.google.android.gms.common.GooglePlayServicesNotAvailableException;

SDK Initialization

The latest version of the Nielsen App SDK allows instantiating multiple instances of the SDK object, which can be used simultaneously without any issue. The sharedInstance API that creates a singleton object was deprecated prior to version 5.1.1. (Version 4.0 for Android)

A maximum of four SDK instances per appid are supported.
When four SDK instances exist, you must destroy an old instance before creating a new one.

The following table contains the list of arguments that can be passed via the AppInfo JSON schema.

The appid is provided by the Nielsen Technical Account Manager (TAM). The appid is a GUID data type and is specific to the application.

Parameter / Argument	Description	Source	Required?	Example
appid	Unique id for the application assigned by Nielsen. It is GUID data type.	Nielsen-specified	Yes	PXXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX
appname	Name of the application	Client-defined	Optional; automatically detected in SDK 6.0.0.4 and above	Nielsen Sample App
sfcode	Nielsen collection facility to which the SDK should connect. DTVR "us" Digital Audio "drm" DCR "dcr"	Nielsen-specified	Yes	dcr-cert
containerID	View ID of the UI element used as player view in application for Viewability	Client-defined	Optional	"1234567"
nol_devDebug	Enables Nielsen console logging. Only required for testing	Nielsen-specified	Optional	"DEBUG"

Debug flag for development environment

Player application developers / integrators can use Debug flag to check whether an App SDK API call made is successful. To activate the Debug flag, Pass the argument @"nol_devDebug":@"INFO", in the JSON string . The permitted values are:

INFO: Displays the API calls and the input data from the application (validate player name, app ID, etc.). It can be used as certification Aid.
WARN: Indicates potential integration / configuration errors or SDK issues.
ERROR: Indicates important integration errors or non-recoverable SDK issues.
DEBUG: Debug logs, used by the developers to debug more complex issues.

Once the flag is active, it logs each API call made and the data passed. The log created by this flag is minimal.

Note: DO NOT activate the Debug flag in a production environment.

Sample SDK Initialization Code

AppSDK() is no longer a singleton object and should be initialized as below.

Initialization of App SDK object through a JSON object

  

try
{
  // Prepare AppSdk configuration object (JSONObject)
  JSONObject appSdkConfig = new JSONObject()
          .put("appid", "PDA7D5EE6-B1B8-XXXX-XXXX-2A788BCXXXCA")
          .put("sfcode", "dcr")
          .put("containerID": "2131558561")
          .put("nol_devDebug", "DEBUG"); // only for debug builds

// Pass appSdkConfig to the AppSdk constructor
mAppSdk = new AppSdk(appContext, appSdkConfig, appSdkListener);
}
catch (JSONException e)
{
  Log.e(TAG, "Couldn’t prepare JSONObject for appSdkConfig", e);
}

Here, appContext is the App context object and appSdkConfig is JSON object for holding the parameters (appid, sfcode) the App passes to the Nielsen App SDK via a JSON string. The appid is obtained from Nielsen operational support and is unique to the app.

The integration of Nielsen App SDK will depend on type of client app.

Ensure that SDK files (AppSdk.jar and libAppSdk.so [App SDK 1.2 Only]) are included under the App’s project and the App SDK is linked to the App (the setting to link App SDK to the App can be found on property page of the App’s project).

APP SDK Error & Event Codes

To view the Error and Event codes for iOS and Android, please review the App SDK Event Code Reference page.

Configure Payload

Handling JSON Metadata

All the SDK methods handles only two types of objects: NSString, NSDictionary. The parameters passed must be either a JSON formatted string or a NSDictionary object. The JSON passed in the SDK must be well-formed.

NSDictionary object
- If an object of unexpected type is passed to the method, the error message will be logged.
- If string has invalid JSON format, the error message will be logged.
JSON value must be string value.
- This includes boolean and numeric values. For example, a value of true should be represented with "true", number value 123 should be "123".
- All the Variable Names like appid, appname, sfcode, dataSrc, title, type etc. are case-sensitive. Use the correct variable name as specified in the documentation.
JSON string can be prepared using either raw NSString or serialized NSDictionary.

JSONObject contentMetadata = new JSONObject()
//SDK Metadata
    .put("type", "content")
    .put("assetid", "vid345-67483")
    .put("program", "Program Name")
    .put("title", "Program S3, EP1")
    .put("length", "3600")
    .put("segB", "CustomSegmentValueB")  //optional
    .put("segC", "CustomSegmentValueC")  //optional
    .put("isfullepisode", "yes")
    .put("airdate", "20161013 20:00:00")

stop

public void stop()

end

When content stop is initiated and content cannot be resumed from the same position (it can only be restarted from the beginning of stream).

public void end()

Example Ad Object

// create ad object
"ad": {
  "type": "preroll",
  "assetid": "AD-ID123"
}

Configure API Calls

Sample API Sequence

A Sample API sequence could follow this flow:

Type	Sample code	Description
On App Start	`[nielsenMeter loadMetadata: contentMetadata];`	// contentMetadata Object contains the JSON metadata for the impression
Start of stream	`[nielsenMeter play: channelName];`	// channelName contains JSON metadata of channel/video name being played
Start of stream	`[nielsenMeter loadMetadata: contentMetadataObject];`	// contentMetadataObject contains the JSON metadata for the content being played
Content	`[nielsenMeter setplayheadPosition: position];`	// playheadPosition is position of the playhead while the content is being played
End of Stream	`[nielsenMeter end];`	// Content playback is completed.

SDK Events

Event	Parameter	Description
'loadMetadata'	content/ad metadata object	Needs to be called at the beginning of each asset
'setPlayheadPosition'	playhead position as integer VOD: \|\| current position in seconds Live: current Unix timestamp (seconds since Jan-1-1970 UTC) Note: 'setPlayheadPosition' has to be called every second	Pass playhead position every second during playback
'stop'	playhead position	Call when content or ads complete playing and pass playhead position
'end'	playhead position in seconds	Call when the current video asset completes playback and pass the playhead position. Example: At the end of the content stream, if the user switches to another piece of content, when the browser is refreshed or closed.

Note: For livestream, send the Unix timestamp; for VOD send the time in seconds as integer. The final playhead position must be sent for the current asset being played before calling stop, end or loadmetadata,.

Life cycle of SDK instance

Life cycle of SDK instance includes four general states:

Initial state – The SDK is not initialized and hence, not ready to process playing information. Once the SDK is moved out of this state, it needs instantiation of the new SDK instance in order to get the instance in the Initial state.
Idle state – The SDK is initialized and is ready to process playing information. Once Initialized, the SDK instance is not processing any data, but is listening for the play event to occur.
Processing state – The SDK instance is processing playing information. The play and loadMetadata calls move the SDK instance into this state. In this state, the SDK instance will be able to process the following calls.
1. setplayheadPosition – Call this API every one second when playhead position timer is fired. If a LIVE event, use the current Unix timestamp (seconds since Jan-1-1970 UTC).
2. stop – Call this API when the playback is paused, switches between content and ad (within the same content playback) or encounters interruptions.
3. end – SDK instance exits from Processing state when this API is called.
Disabled state – The SDK instance is disabled and is not processing playing information. SDK instance moves into this state in one of the following scenarios.
1. Initialization fails
2. appDisableApi is set to true

Note: For API Version 5.1 and above, App SDK will fire data pings and continue measurement even after the user has opted out from Nielsen measurement on a device. The data ping will be marked as opted-out ping.
Note: In case of any interruptions during playback due to alarm, calendar, call, flight mode, Wi-Fi toggle, channel change, etc., call stop to stop the measurement.

As soon as the playback resumes, call play, loadMetadata and playheadPosition

API Call Sequence

Use Case 1: Content has no Advertisements

Call play() with channelName JSON as below.

{
   "channelName": "TheMovieTitle"
}

Call loadMetadata() with JSON metadata for content as below.

{
  "type": "content",
  "assetid": "vid345-67483",
  "program": "ProgramName",
  "title": "Program S3, EP1",
  "length": "3600",
  ...
}

Call setPlayheadPosition() every one second until a pause / stop. Use the sample API sequence below as a reference to identify the specific events that need to be called during content playback without ads.

Type	Sample code	Description
Start of stream	`mAppSdk.play(channelName);`	// channelName contains JSON metadata of channel/video name being played
Start of stream	`mAppSdk.loadMetadata(contentMetaDataObject);`	// contentMetadataObject contains the JSON metadata for the content being played
Content	`mAppSdk.setPlayheadPosition(playheadPosition);`	// position is position of the playhead while the content is being played
End of Stream	`mAppSdk.end();`	// Content playback is completed.

Use Case 2: Content has Advertisements

Call play() with channelName JSON as below.

{
   "channelName": "TheMovieTitle"
}

Call loadMetadata() with JSON metadata for ad as below.

{
   "type": "preroll",
   "assetid": "ad=123"
}

Note: In case the individual ad details are not available, send ad pod (presence) details through the loadMetadata and playhead position through playheadPosition.

Call setPlayheadPosition() every one second until a pause / stop / another loadMetadata() is called. Playhead should be passed for the entire duration of ad pod, if the ad pod details are passed as part of loadMetadata().

Ad Content

    long pos = mAdPlayer.videoPosition() / 1000;
   if (mAppSdk != null)
   {
     mAppSdk.setPlayheadPosition(pos);
   }

Note: The playhead positions for ad and content should be maintained separately.

The sample API sequence can be used as a reference to identify the specific events that need to be called during content and ad playback.

Type	Sample code	Description
Start of stream	`mAppSdk.play(channelName);`	// channelName contains JSON metadata of channel/video name being played
Start of stream	`mAppSdk.loadMetadata(contentMetaDataObject);`	// contentMetadataObject contains the JSON metadata for the content being played
Preroll	`mAppSdk.loadMetadata(prerollMetadataObject);`	// prerollMetadataObject contains the JSON metadata for the preroll ad
	`mAppSdk.setPlayheadPosition(playheadPosition);`	// position is position of the playhead while the preroll ad is being played
	`mAppSdk.stop();`	// Call stop after preroll occurs
Content	`mAppSdk.loadMetadata(contentMetaDataObject);`	// contentMetadataObject contains the JSON metadata for the content being played
	`mAppSdk.setPlayheadPosition(playheadPosition);`	// position is position of the playhead while the content is being played
	`mAppSdk.stop();`	// Call stop after the content is paused (ad starts)
Midroll	`mAppSdk.loadMetadata(midrollMetaDataObject);`	// midrollMetadataObject contains the JSON metadata for the midroll ad
	`mAppSdk.setPlayheadPosition(playheadPosition);`	// position is position of the playhead while the midroll ad is being played
	`mAppSdk.stop();`	// App moves to background(midroll pauses)
	`mAppSdk.loadMetadata(midrollMetaDataObject);`	// App moves to foreground (midroll resumes)
	`mAppSdk.setPlayheadPosition(playheadPosition);`	// playheadPosition is position of the playhead while the midroll ad is being played
	`mAppSdk.stop();`	// Call stop after midroll occurs
Content (End of stream)	`mAppSdk.loadMetadata(contentMetaDataObject);`	// contentMetadataObject contains the JSON metadata for the content being played
	`mAppSdk.setPlayheadPosition(playheadPosition);`	// position is position of the playhead while the content is being played
	`mAppSdk.stop();`	// Always call stop irrespective of postroll is followed or not
End of Stream	`mAppSdk.end();`	// Call end() at the end of content
Postroll	`mAppSdk.loadMetadata(postrollMetaDataObject);`	// postrollMetadataObject contains the JSON metadata for the postroll ad
	`mAppSdk.setPlayheadPosition(playheadPosition);`	// position is position of the playhead while the postroll ad is being played
	`mAppSdk.stop();`	// Call stop after postroll occurs

Note: Each Ad playhead should reset or begin from 0 at ad start. When content has resumed following an ad break, playhead position must continue from where previous content segment was left off.

Handling Foreground and Background states

Foreground/Background state measurement is a requirement of Nielsen AppSDK implementation which is especially crucial for static measurement. It may be implemented in multiple ways for Android. This includes

Enable the Nielsen SDK to measure background/foreground state by makingthe relevant update to the AndroidManifest.
Integrate Nielsen’s SdkBgFgDetectionUtility class within your Custom Application Class.
Custom implementation of the required methods within your application.

ForeGround/Background Measurement via AndroidManifest

The simplest way to measure the app background/foreground state is to add the following application tag to the Manifest XML. Integrating this into the Manifest XML will enable the SDK to measure app state directly. This approach is supported for Android 4.0 and up only; it requires that the application class is not in use for some other purpose.

<application android:name="com.nielsen.app.sdk.AppSdkApplication">

Using the Android SdkBgFbDetectionUtility Class

For developers who are already using the application class, it is recommended that background/foreground state is implemented using the SdkBgFgDetectionUtility class. The SdkBgFgDetectionUtility class is compatible with Android 4+ and has been made available to Nielsen clients. (You will need to copy/paste the code provided into a file).

Manual Background/ForeGround State Management

In cases where the developer is not able to use the AndroidManifest.xml solution nor the Nielsen provided SdkBgFgDetectionUtility class the developer will need to manually identify the change of state through the application and call the respective API (appInForeground() or appInBackground()) to inform the SDK regarding the change of state from background to foreground or foreground to background.

The SDK is informed about app state using the below methods.

AppLaunchMeasurementManager.appInForeground(getApplicationContext());
AppLaunchMeasurementManager.appInBackground(getApplicationContext());

Within the lifecycle of individual activities, onResume() and onPause() are best suited to providing indication of the app state.

Correct measurement of the foreground/background state is crucial to Static App measurement within Nielsen Digital Content Ratings (DCR).

Interruptions during playback

As part of integrating Nielsen App SDK with the player application, the Audio / Video app developer needs to handle the following possible interruption scenarios:

Pause / Play
Network Loss (Wi-Fi / Airplane / Cellular)
Call Interrupt (SIM or Third party Skype / Hangout call)
Alarm Interrupt
Content Buffering
Device Lock / Unlock (Video players only, not for Audio players)
App going in the Background/Foreground (Video players only, not for Audio players)
Channel / Station Change Scenario
Unplugging of headphone

In case of encountering one of the above interruptions, the player application needs to

Call stop immediately (except when content is buffering) and withhold sending playhead position.
Start sending pings – 'loadMetadata' and 'playheadPosition' for the new viewing session, once the playback resumes.

Please see the Interruption Scenarios Page for more details

Pre-Certification Checklists

After the application is ready to be sent for Nielsen Certification, please go through the Digital Pre-Certification Checklist App SDK and ensure the app behaves as expected, before submitting to Nielsen.

Privacy and Opt-Out

There are currently 3 flavors of the Nielsen SDK:

Global Android SDK Opt-out - managed by Opt out of Ads Personalization setting on device (preferred approach).
Global Android SDK No Ad Framework Optout - Direct call to SDK. Can be used without Google Play Services or when using the noAd version of the SDK.
Global Android SDK No ID Optout - Direct call to SDK. Should be used for Kids Category.

Global Android SDK Opt-out

OS-level Opt-out method available on Nielsen Android when the Google Play services APIs have been setup in your project.

The Nielsen SDK automatically leverages the Android's Opt out of Ads Personalization setting. The user is opted out of demographic measurement if the OS-level Opt out of Ads Personalization setting is enabled. As a publisher, you cannot override this setting.

Webview Element

It is a requirement to display a WebView element whose loadUrl is set to the value obtained from optOutURL. If using the Global Android SDK, this optOutURL informs the user how to deactivate/activate “Out of Ads Personalization”.

If you are implementing on Android TV or Fire TV here are your Opt Out verbiage options : https://engineeringportal.nielsen.com/docs/DCR_Video_%26_Static_CTV_Device_SDK_Privacy

Retrieve current Opt-Out preference

Whether the user is opted out via OS-level Opt-out or via App-level Opt-out, the current Opt-Out status as detected by the SDK is available via the getOptOutStatus() property in the Nielsen Android SDK API. appSdk.getOptOutStatus()

Global Android SDK No Ad Framework Optout

The No Ad Framework Optout can be used when the host application does not leverage Google Play Services such as when using the noAd version or the NoID version.

Nielsen Android SDK 5.1.1.18 and above will check for OS-level opt-out first, if available. The user will be opted out if indicated at the OS-level OR the App-level.

The No Ad Framework Optout method works as follows:

Get the current Nielsen opt-out URL via userOptOutURLString()
Display a WebView element whose loadUrl is set to the value obtained from userOptOutURLString()
Detect if the WebView URL changes to a special URL that indicates Opt-in, or Opt-out and close the WebView
- Opt-out if the WebView URL = nielsenappsdk://1
- Opt-in if the WebView URL = nielsenappsdk://0

Pass the detected URL to the userOptOut() function

Example:

appSdk.userOptOut("nielsenappsdk://1");  // User opt-out

Global Android SDK No ID Optout (Kids_Category)

If you are building an app that will be listed in the Kids Category:

Ensure that you are using the NoID version of the Nielsen SDK Framework.
Immediately following the initialization of the Nielsen SDK ensure you call the userOptOut API with Opt out selection:

appSdk.userOptOut("nielsenappsdk://1");  // User opt-out

OptOut Example Code

Below you will find some sample code for the:

Global Android SDK - managed by Opt out of Ads Personalization setting on device (preferred approach).
Global Android noAd Framework - Use if Google Play APIs are unavailable or running noAd version.
It is currently not required to display an OptOut page for the NoID/Kids Build of the SDK.

Global OptOut Example

The below code is an AndroidX example of displaying the Nielsen Privacy page to the user. Please see the next section if using the No Ad Framework build

public class OptOutActivity extends AppCompatActivity implements IAppNotifier {

    WebView webView;
    AppSdk appSdk;

    @Override
    public void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_optout);
        webView = (WebView) findViewById(R.id.webView);
        webView.getSettings().setJavaScriptEnabled(true);

        webView.setWebViewClient(new WebViewClient() {
            @SuppressWarnings("deprecation")
            @Override
            public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
                Toast.makeText(OptOutActivity.this, description, Toast.LENGTH_SHORT).show();
            }
            @TargetApi(android.os.Build.VERSION_CODES.M)
            @Override
            public void onReceivedError(WebView view, WebResourceRequest req, WebResourceError rerr) {
                // Redirect to deprecated method, so you can use it in all SDK versions
                onReceivedError(view, rerr.getErrorCode(), rerr.getDescription().toString(), req.getUrl().toString());
            }

        });
        String url = appSdk.userOptOutURLString();   // Request Optout URL from NielsenSDK
        webView.loadUrl(url);                         //Display to the user in a Webview
    }
    @Override
    public void onBackPressed() {
        super.onBackPressed();
        mSdkInterface.getSDK(appSdk);
    }
    @Override
    protected void onDestroy() {
        super.onDestroy();
        if (appSdk != null)
        {
            appSdk.close();
            appSdk = null;
        }
    }

The below code is an AndroidX example of displaying the Nielsen Privacy page to the user with the No Ad Framework SDK Build.

public class OptOutActivity extends AppCompatActivity implements IAppNotifier {

    WebView webView;
    AppSdk appSdk;

    @Override
    public void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_optout);
        webView = (WebView) findViewById(R.id.webView);
        webView.getSettings().setJavaScriptEnabled(true);

        webView.setWebViewClient(new WebViewClient() {
            @SuppressWarnings("deprecation")
            @Override
            public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
                Toast.makeText(OptOutActivity.this, description, Toast.LENGTH_SHORT).show();
            }
            @TargetApi(android.os.Build.VERSION_CODES.M)
            @Override
            public void onReceivedError(WebView view, WebResourceRequest req, WebResourceError rerr) {
                // Redirect to deprecated method, so you can use it in all SDK versions
                onReceivedError(view, rerr.getErrorCode(), rerr.getDescription().toString(), req.getUrl().toString());
            }

  
            @Override
            public boolean shouldOverrideUrlLoading(WebView view, String url) {

                if(url.contains("nielsen")){
                    // If url value = "nielsenappsdk://1 it means the user selected Opt Out
                    // If url value = "nielsenappsdk://0" it means the user selected Opt-In
                    appSdk.userOptOut(url);
                }
                return true;
            }

        });
        String url = appSdk.userOptOutURLString();   // Request Optout URL from NielsenSDK
        webView.loadUrl(url);                         //Display to the user in a Webview
    }
    @Override
    public void onBackPressed() {
        super.onBackPressed();
        mSdkInterface.getSDK(appSdk);
    }
    @Override
    protected void onDestroy() {
        super.onDestroy();
        if (appSdk != null)
        {
            appSdk.close();
            appSdk = null;
        }
    }
}

Retrieve current Opt-Out preference

Whether the user is opted out via OS-level Opt-out or via App-level Opt-out, the current Opt-Out status as detected by the SDK is available via the getOptOutStatus() property in the Nielsen Android SDK API. appSdk.getOptOutStatus()

Going Live

Following Nielsen testing, you will need to:

Disable Debug Logging: Disable logging by deleting {nol_devDebug: 'DEBUG'} from initialization call.
Notify Nielsen: Once you are ready to go live, let us know so we can enable you for reporting. We will not be able to collect or report data prior to receiving notification from you.

Going Live

Following Nielsen testing, users need to make one update to the initialization call to ensure that the site is being measured properly.

Debug Logging: Disable logging by deleting {nol_sdkDebug: 'DEBUG'} from initialization call.

Note: before going live you have to inform Nielsen team - this is necessary, because Nielsen team has to adjust internal configuration parameter to enable data collection. Without that notification no data will be collected and no data will be reported.

Sample Applications

The below sample applications have been designed to show the API's functionality and are broken into two distinct categories:

Basic - To show the functionality of the Nielsen API using a standard no-frills player.

Advanced - Nielsen API integrated into a custom video player is bundled with the SDK.
