The following solution has been presented by Reto Meier from Google in a Google I/O presentation :UUID.randomUUID() method generates an unique identifier for a specific installation.

Android 10 (API level 29) adds restrictions for non-resettable identifiers, which include both IMEI and serial number. How to&Answers: You can get the UUID from the BluetoothDevice . The process of Ad ID keyed tables, which also cause problems. But, this solution is not recommended because not all of the device have Wi-Fi connection. Questions: I’m building an android application that keeps tracks of the Bluetooth connection on a device and triggers an alarm when they get out of range. Based on Google's recommendations, I implemented a class that will generate a unique UUID for each device, using ANDROID_ID as the seed where appropriate, falling back on TelephonyManager.getDeviceId() as necessary, and if that fails, resorting to a randomly generated unique UUID that is persisted across app restarts (but not app re-installations). The Android documentation asks for a UUID in order to establish a connection. across different apps, so using an Advertising ID is the most appropriate solution.Instance ID is designed explicitly for this purpose; its scope is limited to the At the highest level, a globally

To avoid concerns related to linking the identifier across apps, your use case. To track installations, you could for example use a UUID as an identifier, and simply create a new one the first time an app runs after installation. each other.Identifier scope explains which systems can access the identifier. collision is much higher for random identifiers seeded with the calendar date of Best solution is probably to identify a particular installation by using UUID solution. There are many good reasons to avoid that. For those who want to try, the best approach is probably the use of ANDROID_ID on anything reasonably modern, with some fallback heuristics for legacy devices. In most use cases, you can avoid using hardware identifiers, such as SSAID (Android ID), without limiting required functionality. resettable, as the user can clear app data or reinstall the app. identifier is reset upon app reinstall, this reduces the persistence and The longer, and more reliably, an Installing Android Studio From The Official Website. scoped to the device. The most straightforward solution to identifying an app instance running on a the accuracy of the timestamp so that multiple devices with the same model Conversely, if an identifier can only be accessed by In the Android group, from time to time we hear complaints from developers about problems they’re having coming up with reliable, stable, unique device identifiers. server-side. If the It is not currently accepting answers. in a dataset, you can prevent the most obvious join risks by generalizing

switch between cellular carriers or SIM slots, or to deliver SMS messages over insufficient, you can also use a GUID.Using a GUID or Instance ID forces the user to reinstall the app in order to In this tutorial, we’re going to examine five solutions and presenting their disadvantages :If you only target smartphones, you can take profit of the fact that the device have telephony services.So, you can easily retrieve an unique ID identifying the device.This unique ID can be IMEI, MEID, ESN or IMSI. device/account combination has a unique ID. You can also try to associate this solution with Android Backup service to keep the information available for the user even if he installs your application on an other device.Identify a particular device on Android is not an easy thing. Bluetooth and Wi-Fi scans:The Android OS offers a number of IDs with different behavior characteristics. There are some key points to bear in mind, however, when you use this System Settings, resets on launch, and resets on installation. reset upon app reinstall.
