constants.installationid: how to "implement it on your own"

blyler · March 15, 2021, 7:05pm

Please provide the following:

SDK Version: 40
Platforms(Android/iOS/web/all): all

Hi, in the documentation for constants under installationid it says:

This property is deprecated and will be removed in SDK 44. Please implement it on your own using expo-application’s androidId on Android and a storage API such as expo-secure-store on iOS and localStorage on Web.

I see so many people asking about a way to identify which device the user is on, so why not have a way to identify the device? I need one in my app. Also, how do you implement it on your own with a storage api? What methods of the storage api generate a unique deviceid? I looked through the Secure Store documentation and I don’t see any methods that generate device id’s. So, not only is installationid being removed, but there’s no assistance, i can find, about how to implement it on your own.

The 4 methods I see in the SecureStore package are: isAvailableAsync(), getItemAsync(), setItemAsync(), and deleteItemAsync(). Which of those can generate a device id or installation id?

Based on [repo] Deprecate installationId by sjchmiela · Pull Request #10997 · expo/expo · GitHub, the code from expo/getInstallationIdAsync.ts at master · expo/expo · GitHub (and .android.ts and .web.ts) could probably help. But I would also appreciate a more official guide on how to do this!

I am looking for the samething.

This property is deprecated and will be removed in SDK 44. Please implement it on your own using expo-application’s androidId on Android and a storage API such as expo-secure-store on iOS and localStorage on Web.

Application.androidId
Android only. The value of Settings.Secure.ANDROID_ID. This is a hexademical string unique to each combination of app-signing key, user, and device. The value may change if a factory reset is performed on the device or if an APK signing key changes. For more information about how the platform handles ANDROID_ID in Android 8.0 (API level 26) and higher, see Android 8.0 Behavior Changes. On iOS and web, this value is null.
Note: In versions of the platform lower than Android 8.0 (API level 26), this value remains constant for the lifetime of the user's device. See the Android_ID official docs for more information.
E.g., "dd96dec43fb81c97"

Application.getIosIdForVendorAsync()
iOS only. Gets the iOS "identifier for vendor" (IDFV) value, a string ID that uniquely identifies a device to the app’s vendor. This method may sometimes return nil, in which case wait and call the method again later. This might happen when the device has been restarted before the user has unlocked the device.
The OS will change the vendor identifier if all apps from the current app's vendor have been uninstalled.
Returns
A Promise that resolves to a string specifying the app's vendor ID. Apps from the same vendor will return the same ID. See Apple's documentation for more information about the vendor ID's semantics.
Examples
await Application.getIosIdForVendorAsync();
// "68753A44-4D6F-1226-9C60-0050E4C00067"

My guess is that the documentation is telling us to use those 2 methods for identifying uniquely the device and then using expo-secure-store/local storage to save and remember those. I am not so sure why we should remember them, do they change? According to the documentation they don’t change.

Hi guys, I’m with the same problem, I just did the update to the SDK41 and the warning of the installationId deprecation appeared, it would be desirable to have an official document on how to make a proper implementation for this, for now what can help us are these links :

github.com

expo/expo/blob/master/packages/expo/src/environment/getInstallationIdAsync.ts

import * as Application from 'expo-application';
import uuidv5 from 'uuid/v5';

let installationId: string | null;
const UUID_NAMESPACE = '29cc8a0d-747c-5f85-9ff9-f2f16636d963'; // uuidv5(0, "expo")

export default async function getInstallationIdAsync() {
  if (installationId) {
    return installationId;
  }

  const identifierForVendor = await Application.getIosIdForVendorAsync();
  const bundleIdentifier = Application.applicationId!;

  // It's unlikely identifierForVendor will be null (it returns null if the
  // device has been restarted but not yet unlocked), but let's handle this
  // case.
  if (identifierForVendor) {
    installationId = uuidv5(`${bundleIdentifier}-${identifierForVendor}`, UUID_NAMESPACE);
  } else {

export default async function getInstallationIdAsync() {
  // Already cached value
  if (installationId) {
    return installationId;
  }

  try {
    // No cached value, fetch from persisted storage
    installationId = localStorage.getItem(INSTALLATION_ID_KEY);
    if (installationId) {
      return installationId;
    }
  } catch (error) {
    // If we weren't able to fetch one (for whatever reason)

good call! we should create something for this.

the basic steps are:

install some persistence library (eg: async storage)
install some library to generate uuids (eg: uuid)
on app start, check if a uuid has been saved to storage. if so, read it and make it available somewhere convenient to use wherever you need it. if not, generate the uuid with and write it to storage, then make it available.

Simple, but not the best solution for Constants.installationId deprecation warning is the following:

import getInstallationIdAsync from 'expo/build/environment/getInstallationIdAsync';

yes, please!

jorgem · April 15, 2021, 3:40pm

I have updated to sdk 41 and I find the same problem and I don’t know how to solve it.

dariocostanzo · April 16, 2021, 1:03pm

I think I will go for the same solution
