Question

我目前正在使用Firebase消息传递云为我的应用推送通知。我正在尝试为推送通知发出自定义通知声音。我相信可以通过在有效负载中放入“ sound：blabla.mp3”来实现，但是我如何在dart页面中定义声音？

Answer 1

AndroidNotificationDetails androidNotificationsDetails = AndroidNotificationDetails(
       'your other channel id',
       'your other channel name',
       'your other channel description',
        importance: Importance.Max,
        priority: Priority.Max,
        enableLights: true,
        playSound: true,
        sound: RawResourceAndroidNotificationSound('notification'),
);

注意：你应该在android/app/src/main/res/raw/notification.mp3中添加notification.mp3文件，不要忘记指定playSound：

playSound: true,

这在前台/后台和应用程序关闭时对我有用。

Answer 2

您可以简单地通过调用声音并在firebase configure方法中播放声音来实现此目的。

class Class:
    def action(self, accounts):
        for account in accounts[9:]:
            try:
                self.browser.get(account)
                time.sleep(5)
                like_button = self.browser.find_element_by_xpath(
                                    u'//button[contains(@class, "Heart")]').click()
                self.count_actions()
                print(self.counter_var)
                yield  # Added.
            except selenium.common.exceptions.NoSuchElementException:
                break

    def count_actions(self):
        self.counter_var += 1

    def main(self):
        while True:
            searched_category = random.choice(pool_categories)
            accounts = self.load_category(searched_category)
            for _ in self.action(accounts):  # Iterate through account checks.
                if self.counter_var < self.max_var:  # Too many actions?
                    break

此操作无效，因为如果应用程序在后台运行，则文件不会播放

要为两个Android都创建自定义通知声音，您需要为您的应用程序预定义通知频道。我使用Flutter Local Notifications插件来做到这一点。您可以在其中为您的Android通知频道指定参数，例如

var androidPlatformChannelSpecifics = AndroidNotificationDetails( 'your other channel id', 'your other channel name', 'your other channel description', sound: RawResourceAndroidNotificationSound('slow_spring_board');

注意：slow_spring_board.mp3存储在应用程序的android\app\src\main\res\raw部分中。调用RawResourceAndroidNotificationSound()

时不要包含文件扩展名

还有其他步骤才能为iOS设备设置它（不支持mp3）。完成所有步骤后，您可以开始处理云消息传递部分，在其中必须参考通知通道ID和声音文件。我建议在该代码中包括音频文件扩展名。

You must create notification channel first with following code

Application.kt

import android.app.NotificationChannel;
import android.app.NotificationManager;
import android.content.Context;
import android.graphics.Color;
import android.os.Build;

import io.flutter.app.FlutterApplication
import io.flutter.plugin.common.PluginRegistry
import io.flutter.plugins.GeneratedPluginRegistrant
import io.flutter.plugin.common.PluginRegistry.PluginRegistrantCallback
import io.flutter.plugins.firebasemessaging.FlutterFirebaseMessagingService
import io.flutter.plugins.pathprovider.PathProviderPlugin;

import io.flutter.plugin.common.MethodChannel
import android.content.ContextWrapper
import android.content.Intent
import android.content.IntentFilter
import android.os.Build.VERSION
import android.os.Build.VERSION_CODES
import android.net.Uri;
import android.media.AudioAttributes;
import android.content.ContentResolver;

class Application : FlutterApplication(), PluginRegistrantCallback {
    override fun onCreate() {
        super.onCreate()
        this.createChannel()
        FlutterFirebaseMessagingService.setPluginRegistrant(this)
    }

    override fun registerWith(registry: PluginRegistry?) {
//        createChannel();
        FirebaseCloudMessagingPluginRegistrant.registerWith(registry);
    }

    private fun createChannel() {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            // Create the NotificationChannel
            val name: String = getString(R.string.default_notification_channel_id)
            val channel = NotificationChannel(name, "default", NotificationManager.IMPORTANCE_HIGH)
            val soundUri = Uri.parse(ContentResolver.SCHEME_ANDROID_RESOURCE + "://"+ getApplicationContext().getPackageName() + "/raw/sample");
            val att = AudioAttributes.Builder()
                    .setUsage(AudioAttributes.USAGE_NOTIFICATION)
                    .setContentType(AudioAttributes.CONTENT_TYPE_SPEECH)
                    .build();
            channel.setSound(soundUri, att)

            val notificationManager: NotificationManager = getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
            notificationManager.createNotificationChannel(channel)

            /*
            val id = mapData["id"]
            val name = mapData["name"]
            val descriptionText = mapData["description"]
            val sound = "sample"
            val importance = NotificationManager.IMPORTANCE_HIGH
            val mChannel = NotificationChannel(id, name, importance)
            mChannel.description = descriptionText





            // Register the channel with the system; you can't change the importance
            // or other notification behaviors after this
            val notificationManager = getSystemService(NOTIFICATION_SERVICE) as NotificationManager
            notificationManager.createNotificationChannel(mChannel)
            completed = true
             */
        }
    }
}

And android manifest.xml

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

    <uses-permission android:name="android.permission.INTERNET"/>

    <!-- io.flutter.app.FlutterApplication is an android.app.Application that

         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

    <application
        android:name=".Application"
        android:label="test App"
        android:icon="@mipmap/ic_launcher">

            <!-- This keeps the window background of the activity showing

            <meta-data
                android:name="io.flutter.app.android.SplashScreenUntilFirstFrame"

            </intent-filter>
        </activity>
        <!-- Don't delete the meta-data below.
             This is used by the Flutter tool to generate GeneratedPluginRegistrant.java -->
        <meta-data
            android:name="flutterEmbedding"
            android:value="2" />

        <meta-data
            android:name="com.google.firebase.messaging.default_notification_channel_id"
            android:value="@string/default_notification_channel_id"/>


        <meta-data android:name="com.google.firebase.messaging.default_notification_icon" android:resource="@drawable/ic_appstore" />

        <meta-data
            android:name="com.google.firebase.messaging.default_notification_color"
            android:resource="@color/colorPrimary" />
    </application>


</manifest>


finally you must put your notification sound.wav file in res/raw

that's it

Answer 5

可以通过flutter_local_notifications插件实现。

首先，您应该为 Android 和 iOS 定义渠道：

const androidPlatformChannel = AndroidNotificationDetails(
  'ANDROID_CHANNEL_ID',
  'Name',
  'Description',
  color: Color.fromARGB(255, 0, 0, 0),
  importance: Importance.max,
  sound: RawResourceAndroidNotificationSound('notification_sound'),
  playSound: true,
  priority: Priority.high,
  showWhen: false,
);

const iOSPlatformChannel = IOSNotificationDetails(
  sound: 'notification_sound.aiff',
  presentAlert: true,
  presentBadge: true,
  presentSound: true,
);

const platformChannel = NotificationDetails(
  android: androidPlatformChannel,
  iOS: iOSPlatformChannel,
);

然后显示通知：

await flutterLocalNotificationsPlugin.show(
      id,
      title,
      body,
      platformChannel,
      payload: notification.payload,
    );

重要提示！notification_sound.aiff 文件应该用 XCode 复制
