Engineering Portal / Digital / DCR & DTVR / Digital Pre-Certification Checklist App SDK

Pre-Certification Checklist

Before starting the certification process, please verify the following steps have been completed.

  • Your Client Service representative should have already discussed a reporting hierarchy with you -- along with a Parent, Brand, and Sub-brand/Channel
  • Your Integration Engineer should have:
    • provided you with an AppID
    • informed you of our Opt-Out requirement for a WebView inside your apps
  • Retrieving AppSDK logs
    • 'nol_devDebug' : 'DEBUG' should be present in initialization call (see below)
    • Android: use adb logcat (note: requires Android Studio)
    • iOS: idevicesyslog (note: requires XCode)

Test Cases

The following lists the test cases along with expected results:


Note: Due to the variable and unique nature of each application, there may be additional testing required by Nielsen that is not listed here. These tests are completed to ensure the quality of data collected. Please speak with your account manager if you have any questions.

Initialization

The first step in the Certification process is to ensure that the Nielsen SDK is initializing at app startup, and that the global metadata values are present.

Keys Value
appid XXXXX-XXXXXX-XXXXX-XXXXX
appname example app name
appversion 2.0
nol_devDebug debug

iOS Example: 

NSDictionary* appInformation = @
{ // AppID is Nielsen-supplied
	 @"appid": @"XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX",
 	 @"appname": @"Sample App Name",
 	 @"appversion": @"2.0",
 	 @"nol_devDebug": @"DEBUG" // required for testing only
}

Android Example: 

JSONObject appSdkConfig = new JSONObject()
          .put("appid", "XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX")
          .put("appname", "Sample App Name")
          .put("appversion","2.0")
          .put("nol_devDebug", "DEBUG"); // required for testing only
// Pass appSdkConfig to the AppSdk constructor
mAppSdk = new AppSdk(appContext, appSdkConfig, appSdkListener);


Config Ping

Confirm that SDK initialization is occurring at app start-up by presence of configuration ping.

Sample Ping: https://cdn-gl.imrworldwide.com/conf/PXXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX.json?devtypid=iPhone8,2&devid=12b9377cbe7e5c94e8a70d9d23929523d14afa954793130f8a3959c7b849aca8 &devname=My%20iPhone&osver=iOS13.6&sysname=iOS&bid=com.nielsen.com.test.config

App ID Description
PXXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX Should be your App ID for the integration

SDK Event Sequence Check

SDK DCR Video Events

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 for DCR.

Type Sample Code Description
Start of stream mAppSdk.play(); // stream starts
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.playheadPosition(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.playheadPosition(playheadPosition); // position is position of the playhead while the content is being played
Midroll mAppSdk.loadMetadata(midrollMetaDataObject); // midrollMetadataObject contains the JSON metadata for the midroll ad
mAppSdk.playheadPosition(playheadPosition); // position is position of the playhead while the midroll ad is being played
mAppSdk.stop(); // Call stop after midroll occurs
Content Resumes mAppSdk.loadMetadata(contentMetaDataObject); // contentMetadataObject contains the JSON metadata for the content being played
mAppSdk.playheadPosition(playheadPosition); // position is position of the playhead while the content is being played
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.playheadPosition(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 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.

SDK DTVR Events

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 for DTVR

Event Parameter Description
'play' Call when starting or resuming a streaming session.

Note:no longer required for SDK version 7.2 or higher.

'loadMetadata' content/ad metadata object Needs to be called at the beginning of each asset to pass type and adModel.
'sendID3' Used to send the ID3 tag payload retrieved from the stream Needs to be called at the beginning of playback
'stop' playhead position Call when content or ads complete playing and pass playhead position

Note:no longer required for SDK version 7.2 or higher.

play()
  • The play() call is required only once per viewing session (until app or SDK instance is killed)
  • Called just before playback commences for first piece of content
Test Case Param Expected Result Pass/Fail
Play channelname Name of Channel
loadMetadata() for DTVR
Test Param Example Value Accepted Values Pass/Fail
loadMetadata type "content" "content"
adModel "1" "1" for linear ads
sendID3() for DTVR Only
  • sendID3 API is a receiver for timed metadata events (ID3 tags)
Test Case Test Condition Pass/Fail
sendID3() Called approx. 10 second

Sample ID3 Tag: www.nielsen.com/X100zdCIGeIlgZnkYj6UvQ==/R8WHe7pEBeqBhu8jTeXydg==/AAICoyitYqlxT7n6aZ0oMCGheFi4CXFp46AMUPZz1lMr_M9tr3_cjee1SHqxrOiVerMDLeyn9 xzocZSKwi746Re8vNOtpNCAZjYABs_J0R25IHpvOc1HS8QHGgD5TgOJeS6gX100zdCIGeIlgZnkYj6UvVJWFNhSVhTiPE0=/00000/46016/00

stop()
  • Indicates one of the following:
  • Playback of content or ad was interrupted
  • Reached end of ad (no parameters or metadata)
Test Case Test Condition Pass/Fail
stop() Called at the end of Ad or interrupt scenario

SDK DCR Static Events

loadMetadata() for App or staticstart() for Browser

Called with correct metadata

Key Description Data Type Value Required? Pass/Fail
type asset type fixed 'static' Yes
assetid Unique ID for each article dynamic custom
(no Special Characters)		 Yes
section section of each site (e.g. section value should be first level in page URL: website.com/section). Limit to 25 unique values dynamic custom Yes
segA custom segment for reporting: Limit to 25 unique values across custom segments (segA + segB + segC) dynamic custom No
segB custom segment for reporting: Limit to 25 unique values across custom segments (segA + segB + segC) dynamic custom No
segC custom segment for reporting: Limit to 25 unique values across custom segments (segA + segB + segC) dynamic custom No

The values passed through the Nielsen keys will determine the breakouts that are seen in reporting. The custom segments (A, B & C) will roll into the sub-brand. To not use custom segments A, B and C, do not pass any value in these keys.

Aggregation Limits There are limits on the number of unique values that can be aggregated on in reporting. The specific limitations by key are:

Key Aggregation Limit
section maximum of 25 unique values (section <= 25)
segA Maximum number of unique values allowed across segA, segB, and segC is 25 (segA + segB + segC<= 25)
segB Maximum number of unique values allowed across segA, segB, and segC is 25 (segA + segB + segC<= 25)
segC Maximum number of unique values allowed across segA, segB, and segC is 25 (segA + segB + segC<= 25)
staticEnd()

Ends DCR static duration measurement of current page/section/asset. Call staticEnd when a new DCR static view event is desired for subsequent loadMetadata call with same section name. The default behavior of AppSDK is to ignore a static loadMetadata call unless the section parameter is different. By calling staticEnd, a new view event can be initiated even in cases where section parameter is the same as previous metaData. This can happen with single-page or single-panel apps.

Test Case Test Condition Pass/Fail
staticEnd() Called when leaving page or using the same section parameter for a different page

Interrupt Scenarios

There are various interrupt scenarios. Test if Applicable

Test Case Description Pass/Fail
Pause / Play
  • Call stop as soon as video is paused and withhold sending the playhead position.
  • Once the video has resumed, call loadMetadata and sendID3 / playheadPosition in that order
Network loss (Wi-Fi / Airplane / Cellular)
  • Call stop as soon as network is lost and withhold sending the playhead position.

Scrubbing

Test Case Test Condition Pass/Fail
Scrub Backward new playhead position is accurate
new playhead continues from new position
Scrub Forward new playhead position is accurate
new playhead continues from new position
Scrub to end final playhead position is passed
end event called at completion of content playback
Scrub past midroll Playhead for content stops

Opt-Out

Users must have access to "About Nielsen Measurement" page. User can click this page from app settings screen.

  • URL to this web page should be called from SDK by invoking optOutURL and opened in 'WebView' / External browser.
  • If the App SDK returns NULL as Opt-Out URL, handle the exception gracefully and retry later.
  • To retrieve the current Opt-Out status of a device, use the optOutStatus method.
Test Case Test Condition Pass/Fail
