使颤动通知（通过firebase）弹出到前台（而不仅仅是状态栏中的图标）

Question

我正在尝试为Flutter应用程序实施通知。

在iPhone（左）上，看起来像预期的一样，通知会显示一小段时间，然后自动隐藏。

但是在Android（右侧，Android 9，摩托罗​​拉）上，它只是在状态栏中显示为图标。我如何使其弹出？现在，我必须向下滑动才能看到内容。

通知是通过Firebase及其PHP-Sdk发送的。

$serviceAccount = ServiceAccount::fromJsonFile('....');

$firebase = (new Factory)
    ->withServiceAccount($serviceAccount);
$messaging = $firebase->createMessaging();

$title = 'Test Titel '.date('YmdHis');
$body = 'Meine Nachricht '.date('YmdHis');
$colkey = 'newmessagtenoti';
$count = 23;

$message = new RawMessageFromArray([
        'notification' => [
            // https://firebase.google.com/docs/reference/fcm/rest/v1/projects.messages#notification
            'title' => $title,
            'body' => $body,
        ],
        'data' => [
            'key_1' => 'Value 1',
            'key_2' => 'Value 2',
        ],

        'android' => [
            // https://firebase.google.com/docs/reference/fcm/rest/v1/projects.messages#androidconfig
            'ttl' => '3600s',
            'priority' => 'high',
            "collapse_key"=> $colkey,

            'notification' => [
                'notification_priority' => 'PRIORITY_MAX',
                'visibility' => 'PUBLIC',
                'title' => $title,
                'body' => $body,
                'notification_count' => $count,
            ],
        ],
        'apns' => [
            // https://firebase.google.com/docs/reference/fcm/rest/v1/projects.messages#apnsconfig
            'headers' => [
                'apns-priority' => '10',
            ],
            'payload' => [
                'aps' => [
                    'alert' => [
                        'title' => $title,
                        'body' => $body,
                    ],
                    'badge' => $count,
                    'apns-collapse-id' =>  $colkey,
                ],
            ],
        ],

    ]);

// $firebase->getMessaging()->send($message);
$report = $messaging->sendMulticast($message, $deviceTokens);

echo 'Successful sends: '.$report->successes()->count().PHP_EOL;
echo 'Failed sends: '.$report->failures()->count().PHP_EOL;

if ($report->hasFailures()) {
    foreach ($report->failures()->getItems() as $failure) {
        echo $failure->error()->getMessage().PHP_EOL;
    }
}

我阅读了全部documentation，但即使优先级很高，它也不会变大。

我想我在Android代码中缺少了一些东西。也许在“ AndroidManifest.xml”中？

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.flut7_push">

    <!-- io.flutter.app.FlutterApplication is an android.app.Application that
         calls FlutterMain.startInitialization(this); in its onCreate method.
         In most cases you can leave this as-is, but you if you want to provide
         additional functionality it is fine to subclass or reimplement
         FlutterApplication and put your custom class here. -->
    <application
        android:name="io.flutter.app.FlutterApplication"

                 until Flutter renders its first frame. It can be removed if

                 defined in @style/LaunchTheme). -->
            <meta-data
                android:name="io.flutter.app.android.SplashScreenUntilFirstFrame"
                android:value="true" />
            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>
                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>            
            <intent-filter>
                <action android:name="FLUTTER_NOTIFICATION_CLICK" />

            </intent-filter>            
        </activity>       

    </application>
</manifest>

看起来您正在研究如何在Android上获取heads-up notification。

[我建议使用FCM's "Data message"，然后在您的FirebaseMessagingService.onMessageReceived实现中处理它，然后按照here的说明优先处理/优先处理。
