AppSDK()
From Engineering Client Portal
AppSdk()
is the public constructor used for initializing the App SDK Analytics framework.
- The reference to the App SDK object returned by the Appsdk constructor.
- App SDK supports multiple instances (max. four) to measure multiple players simultaneously.
- context, appInfo parameters are mandatory and should not be NULL values.
- The constructor should never return null.
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" : "" + "I" + "",",
while initializing the App SDK object. The permitted values are- 'I' (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.
- 'W' (WARNING): Indicates potential integration / configuration errors or SDK issues.
- 'E' (ERROR): Indicates important integration errors or non-recoverable SDK issues.
- 'D' (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 production evironment.

Notes
JSON object for appInfo
The complete list of arguments that can be passed via the AppInfo JSON schema for the API are as follows: (The appid is provided by the Nielsen Technical Account Manager (TAM). The appid is a GUID data type and is specific to the application.)

JSONObject appSdkConfig = new JSONObject()
.put("appid", "PXXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX")
.put("sfcode", "uat-cert")
.put("custom_key1", "custom_value1")
.put("custom_key2", "custom_value2");
// Pass appSdkConfig to the AppSdk constructor
mAppSdk = new AppSdk(appContext, appSdkConfig, appSdkListener);
}
JSON string format for appInfo
The required items are application ID (appid), designated market area (dma), Nielsen-assigned data node (sfcode), and the country code (ccode).
Note: Notice that all quotes inside the string are escaped with a backslash (\).
"{"appid":"PXXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX,"sfcode":"us"}"
iAppNotifier
Client apps can subscribe to the App SDK event listener to be notified about App SDK events. To implement this feature, create a plain old java object (POJO) that implements the interface com.nielsen.app.sdk.IAppNotifier
. Do not implement with the main activity class as this creates a strong reference and interferes with memory release.
//pass the implementing object to the AppSdk constructor in order to subscribe to the eventlistener:
mAppSdk = new AppSdk(context, appInfo,iappNotifierObject)
Optionally, implement an object derived from the interface, as below. This object will allow listening for events within the App SDK.
public interface iAppNotifier
{
public void onAppSdkEvent(long timestamp, int code, String description);
}
Note that implementing the event listener is optional.
AppSdk events
There are three events currently exposed on the App SDK.
public static final int EVENT_INITIATE = 2000;
- App SDK notifies that it is going to be initialized.
public static final int EVENT_STARTUP = 2001;
- The App SDK has just started up. It will happen only after the App SDK has received a valid config file from Nielsen. This is the location in the code to acquire value of
userOptOutURLString()
.
public static final int EVENT_SHUTDOWN = 2002;
- The App SDK is shutting down. It will happen only when the App SDK is destroyed.
