Adobe Launch Extensions
Adobe Launch Extensions are building blocks for mobile application development. The necessary functionality can be implemented independently and put to separate Extensions, but make them able to communicate using Events. These Extensions are live in adobe launch environment and can be used by clients who develop their mobile applications using adobe launch mobile property.
Nielsen AppSDK Extension
Nielsen provides the Adobe Launch Extension based on AppSDK for measuring the video/audio content. It has the name Nielsen AppSDK Extension and is available for android and iOS mobile platforms.
Extension Installation and Configuration
Nielsen has developed Extensions to simplify adding Nielsen measurement into your video stream. The first step is to create and publish a property which is outlined in the Getting Started Guide.
Install the Extension
Nielsen provides three Adobe Launch Extensions that can be integrated to an html page containing any number of video players. It allows clients to add the reporting functionality to their site by putting several lines of JavaScript code into the page.
BSDK extension
BSDK extension integrates the Nielsen BSDK, initializes BSDK instances that can be used by any other extension or from the client’s page directly.
VJS (VideoJS) extension
VJS extension subscribes to standard media events fired by VideoJS player, processes data provided by the user and taken from player, and calls BSDK API (trackevent).
IMA extension
IMA extension subscribes to events fired by the IMA plugin, processes data provided by the user and taken from IMA, and calls BSDK API (trackEvent).
Build the Extension
After the Extension is configured, it can be “built” under the “library” on the Publishing page with other “libraries”.
Add a New library
Select to add a new library
Set the name, chose Environment (Production, Staging, Development):
Save and Build
Add all changed resources. When you get the Extension configured, it will appear in the list of changed resources. Select the Latest revision and press “Select & Create a New Revision” button:
Confirm
Once built, it will appear in the list of Development libraries:
Multi-instance support
The user’s page can contain several players. The user creates BSDK, VJS and IMA extension instances for each player. They should be bound by any string identifier, e.g. a player name. This value must be set in "sdk_instance_name" field of “ext_opt” object for all extensions to bind them.
Prerequisites
Before you begin, ensure that you have an Appid. This is a Unique ID assigned to the player/site and configured by product. If you do not have an AppID , please review the OnBoarding Guide.
