[Google Play services](https://developers.google.com/android)\noffers a privacy-friendly option called [*app set ID*](https://developers.google.com/android/reference/com/google/android/gms/appset/AppSetIdInfo).\n\nApp set ID scope\n----------------\n\nThe app set ID can have one of the following defined scopes. To determine which\nscope a particular ID is associated with, call\n[`getScope()`](https://developers.google.com/android/reference/com/google/android/gms/appset/AppSetIdInfo#getScope()).\n| **Caution:** When Google Play services updates from a version that only supports app scope to a version that supports developer scope, the app set ID's value is reset automatically, without any developer action. See [other reasons developers\n| shouldn't rely on a cached value of the app set ID](#dont-rely-on-cached-value).\n\n### Google Play developer scope\n\n| **Note:** The app set SDK attempts to return app set IDs that have the developer scope without any additional developer action, unless the app satisfies the conditions for app scope, described below.\n\nFor apps that are installed by the Google Play store, the app set ID API returns\nan ID scoped to the set of apps published under the same Google Play developer\naccount.\n\nFor example, suppose you publish two apps under your Google Play developer\naccount and both apps are installed on the same device through the Google Play\nstore. The apps share the same app set ID on that device. The ID is the same\neven if the apps are signed by different keys.\n\n### App scope\n\nUnder any of the following conditions, the app set ID SDK returns an ID unique\nto the calling app itself on a given device:\n\n- The app is installed by an installer other than the Google Play store.\n- Google Play services is unable to determine an app's Google Play developer account.\n- The app is installed on a device without Google Play services.\n\nDon't rely on a cached value of app set ID\n------------------------------------------\n\nUnder any of the following conditions, the app set ID for a given set of Google\nPlay store-installed apps on a device can be reset:\n\n- The app set ID API hasn't been accessed by the groups of apps that share the same ID value for over 13 months.\n- The last app from a given set of apps is uninstalled from the device.\n- The user performs a factory reset of the device.\n\nYour app should use the SDK to retrieve the ID value every time it's needed.\n\nAdd the app set ID SDK to your app\n----------------------------------\n\nThe following snippet shows an example `build.gradle` file that uses the app set\nID library: \n\n dependencies {\n implementation 'com.google.android.gms:play-services-appset:16.1.0'\n }\n\nThe following sample snippet demonstrates how you can retrieve the app set ID\nasynchronously using the [Tasks\nAPI](https://developers.google.com/android/guides/tasks) in Google Play\nservices: \n\n### Kotlin\n\n```kotlin\nval client = AppSet.getClient(applicationContext) as AppSetIdClient\nval task: Task\u003cAppSetIdInfo\u003e = client.appSetIdInfo as Task\u003cAppSetIdInfo\u003e\n\ntask.addOnSuccessListener({\n // Determine current scope of app set ID.\n val scope: Int = it.scope\n\n // Read app set ID value, which uses version 4 of the\n // https://en.wikipedia.org/wiki/Universally_unique_identifier.\n val id: String = it.id\n})\n```\n\n### Java\n\n```java\nContext context = getApplicationContext();\nAppSetIdClient client = AppSet.getClient(context);\nTask\u003cAppSetIdInfo\u003e task = client.getAppSetIdInfo();\n\ntask.addOnSuccessListener(new OnSuccessListener\u003cAppSetIdInfo\u003e() {\n @Override\n public void onSuccess(AppSetIdInfo info) {\n // Determine current scope of app set ID.\n int scope = info.getScope();\n\n // Read app set ID value, which uses version 4 of the\n // https://en.wikipedia.org/wiki/Universally_unique_identifier.\n String id = info.getId();\n }\n});\n```"]]
