In Android 10 getDeviceID value is null

Question

In android 10, couldn't get device id using permission "READ_PHONE_STATE". I got an error while trying to get deviceID "The user 10296 does not meet the requirements to access device identifiers". I referred the developer site, but couldn't get proper solution. Also "READ_PRIVILEGE_PHONE_STATE" permission also not accessible.

Please prefer any solution to get deviceID from Android 10 mobile's and help me to resolve this issue. Thanks in advance

Answer 1

getDeviceId() has been deprecated since API level 26.

"READ_PRIVILEGE_PHONE_STATE" is only accessible by The best practices suggest that you should "Avoid using hardware identifiers." for unique identifiers. You can use an instance id from firebase e.g FirebaseInstanceId.getInstance().getId();.

Or you can generate a custom globally-unique ID (GUID) to uniquely identify the app instance e.g String uniqueID = UUID.randomUUID().toString();

or the least recommended way

String deviceId = android.provider.Settings.Secure.getString(
                context.getContentResolver(), android.provider.Settings.Secure.ANDROID_ID);

Answer 2

You can also use this one, it's getting token from Firebase:-

String deviceId = FirebaseInstanceId.getInstance().getToken();

and this way is also working:-

String deviceId = UUID.randomUUID().toString();
