@andreaowu CI is failing here due to trailing commas which was only introduced in Kotlin recently. We are running an old version of ktlint. I'll put up a PR to fix it

) Copying the snippets from firebase/quickstart-android#1453 to this repo so that they can be added to the docs. Having these snippets on the other repo makes it harder to maintain the samples. Having them on this repo instead should be safer.

The new values need to be applied to the SharedPreferences after they're edited:
Suggested change
| preferences.edit().putLong("lastRefreshDate", updatedTime) | |
| preferences.edit().putLong("lastRefreshDate", updatedTime).apply() |
|

Since this property is only used in this class, we can make it private
Suggested change
| val IS_OPTIMIZE = true | |
| private val IS_OPTIMIZE = true |
|
|
||
| // As an optimization, store today’s date in Android cache | ||
| val preferences = this.getSharedPreferences("default", Context.MODE_PRIVATE) | ||

Don't forget to call apply() after editing your preferences:
Suggested change
| preferences.edit().putLong("lastDeviceRefreshDate", Date().time) | |
| preferences.edit().putLong("lastDeviceRefreshDate", Date().time).apply() |
| import com.google.firebase.messaging.FirebaseMessagingService | ||
| import com.google.firebase.messaging.RemoteMessage | ||
| import com.google.firebase.quickstart.fcm.R | ||
| import java.util.* |
| || lastDeviceRefresh.before(lastGlobalRefresh)) { | ||
| // Get token, store into Firestore, and update cache | ||
| getAndStoreRegToken() | ||
| preferences.edit().putLong("lastGlobalRefreshDate", lastDeviceRefresh.time) |
