Order push notifications are sent without android.priority, so they are held while the device is in Doze

この issue は、ファイル Fleetbase\Support\PushNotification::createFcmMessage() を指しています。まず、コードベース内でこのメソッドを見つけてください。現在のメッセージ構築と、Android の優先度設定に関する Firebase Cloud Messaging (FCM) のドキュメントを確認します。修正には、カスタムペイロードに 'priority' => 'high' を含む 'android' 配列を追加することが含まれます。変更後にプッシュ通知を送信し、Doze モードのデバイスに迅速に届くことを確認してテストしてください。

Summary

Fleetbase\Support\PushNotification::createFcmMessage() builds the FCM message without an Android priority (android.priority). In practice the device treats order pushes (OrderAssigned, OrderDispatched, …) as normal priority, and Android holds normal-priority messages while the device is in Doze. A driver whose phone has been locked and stationary for a while does not get the "order dispatched" push until they unlock, move or charge the phone.

Impact

Drivers miss or get late order notifications. This is the most important push the Navigator app receives. The behaviour is intermittent, so it is easy to misdiagnose:

• With the phone locked for a short time (light Doze), pushes arrive.
• After ~30–60 min locked and stationary (deep Doze), they don't. They show up all at once when the phone is plugged in or unlocked.

Firebase accepts the message in both cases (a message id is returned), so nothing on the server side reports an error.

Versions

Fleetbase v0.7.63 (core-api v1.6.62), laravel-notification-channels/fcm 4.5.0, kreait/firebase-php 7.24.1. Device: Xiaomi phone with HyperOS, app battery setting "No restrictions".

Reproduction

1. Log a driver into the Navigator app on an Android phone, then lock the phone and leave it stationary, unplugged, for ~60 min.
2. Dispatch an order assigned to that driver. The push is accepted by FCM but is not displayed.
3. Plug in the charger or unlock the phone: the push appears.

Controlled test on the same phone, after ~60 min locked and two minutes apart:

• A message identical to createFcmMessage()'s output was not delivered.
• The same message with android.priority = high was delivered immediately.

With the phone locked for only ~20 min, both were delivered.

Suggested fix

Set the Android priority explicitly in createFcmMessage():

->custom([
    'android' => [
        'priority'     => 'high',
        'notification' => [
            'color' => '#4391EA',
            'sound' => 'default',
        ],
        'fcm_options' => [
            'analytics_label' => 'analytics',
        ],
    ],
    // apns unchanged
])

High priority is appropriate here: these are user-visible notifications about time-sensitive work, which is the use case FCM documents for high priority.
