Template:Android SDK Initialization

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)

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

Parameter / Argument	Description	Source	Required?	Example
appid	Unique Nielsen ID for the application. The ID is a GUID data type. If you did not receive your App ID, let us know and we will provide you.	Nielsen-specified	Yes	PXXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX
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("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) 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).
