+# Adobe Experience Platform Identity for Edge Network Extension - Android

+
+### setAdvertisingIdentifier
+
+When this API is called with a valid advertising identifier, the Identity for Edge Network extension includes the advertising identifier in the XDM Identity Map using the _GAID_ (Google Advertising ID) namespace. If the API is called with the empty string (`""`), `null`, or the all-zeros UUID string values, the GAID is removed from the XDM Identity Map (if previously set).
+
+The GAID is preserved between app upgrades, is saved and restored during the standard application backup process, and is removed at uninstall.
+
+> **Warning**  
+> In order to enable collection of the user's current advertising tracking authorization selection for the provided advertising identifier, you need to install and register the [AEPEdgeConsent](https://aep-sdks.gitbook.io/docs/foundation-extensions/consent-for-edge-network) extension and update the [AEPEdge](https://aep-sdks.gitbook.io/docs/foundation-extensions/experience-platform-extension) dependency to minimum 1.3.2.
+
+> **Note**  
+> These examples require Google Play Services to be configured in your mobile application, and use the Google Mobile Ads Lite SDK. For instructions on how to import the SDK and configure your `ApplicationManifest.xml` file, see [Google Mobile Ads Lite SDK setup](https://developers.google.com/admob/android/lite-sdk).
+
+> **Note**  
+> These are just implementation examples. For more information about advertising identifiers and how to handle them correctly in your mobile application, see [Google Play Services documentation about AdvertisingIdClient](https://developers.google.com/android/reference/com/google/android/gms/ads/identifier/AdvertisingIdClient).
+
+#### Java
+
+##### Syntax
+
+```java
+public static void setAdvertisingIdentifier(final String advertisingIdentifier);
+```
+- _advertisingIdentifier_ is an ID string that provides developers with a simple, standard system to continue to track ads throughout their apps.
+
+##### Example
+
+```java
+...
+@Override
+public void onResume() {
+    super.onResume();
+    ...
+    new Thread(new Runnable() {
+        @Override
+        public void run() {
+            String advertisingIdentifier = null;
+
+            try {
+                AdvertisingIdClient.Info adInfo = AdvertisingIdClient.getAdvertisingIdInfo(getApplicationContext());
+                if (adInfo != null) {
+                    if (!adInfo.isLimitAdTrackingEnabled()) {
+                        advertisingIdentifier = adInfo.getId();
+                    } else {
+                        MobileCore.log(LoggingMode.DEBUG, "ExampleActivity", "Limit Ad Tracking is enabled by the user, cannot process the advertising identifier");

+
+            } catch (IOException e) {
+                // Unrecoverable error connecting to Google Play services (e.g.,
+                // the old version of the service doesn't support getting AdvertisingId).
