我正在从 Firebase 向我的 Android 应用程序发送推送通知,但它只在收到通知时播放默认声音。
我在 fcm 通知对象中设置了自定义声音参数 {“sound”:”notificationsound.mp3”}
并且该文件存在于 res/raw 文件夹中,根据 (https://firebase.google.com/docs/cloud-messaging/http-server-ref )
但它仍然在所有应用程序状态(背景、前景和已终止)上播放默认声音。
这是我在 Android 上发送通知的请求正文:
{
"to" : “some id”,
"notification": {
"title":"asdasd",
"body":"sdsad",
"click_action" : "MAIN",
"sound":"notificationsound.mp3"
},
"data": {
"title" : "Something",
"body" : "Important",
"type" : "message"
},
"priority": "high"
}
如何播放自定义通知声音。
最佳答案
我也在寻找android中firebase通知的自定义声音的解决方案,我已经通过Notification Channel解决了这个问题。
我创建了一个带有自定义声音的通知 channel ,该声音在应用程序后台状态下收到通知后播放。
您可以引用以下通知 channel 的链接。
https://medium.com/exploring-android/exploring-android-o-notification-channels-94cd274f604c
https://developer.android.com/training/notify-user/channels
您需要将您的 mp3 文件放在 /res/raw/ 路径中。
请找到代码。
NotificationManager notificationManager = (NotificationManager) getActivity().getSystemService(NotificationManager.class); // If you are writting code in fragment
或
NotificationManager notificationManager = (NotificationManager) getSystemService(NotificationManager.class); // If you are writting code in Activity
createNotificationChannel 函数
private void createNotificationChannel() {
Uri sound = Uri.parse(ContentResolver.SCHEME_ANDROID_RESOURCE + "://" + context.getPackageName() + "/" + R.raw.sample); //Here is FILE_NAME is the name of file that you want to play
// Create the NotificationChannel, but only on API 26+ because
// the NotificationChannel class is new and not in the support library if
(Build.VERSION.SDK_INT >= Build.VERSION_CODES.O)
{
CharSequence name = "mychannel";
String description = "testing";
int importance = NotificationManager.IMPORTANCE_DEFAULT;
AudioAttributes audioAttributes = new AudioAttributes.Builder()
.setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION)
.setUsage(AudioAttributes.USAGE_ALARM)
.build();
NotificationChannel channel = new NotificationChannel("cnid", name, importance);
channel.setDescription(description);
channel.enableLights(true); channel.enableVibration(true);
channel.setSound(sound, audioAttributes);
notificationManager.createNotificationChannel(channel);
}
};
createNotificationChannel();
要实现这一点,您需要在 firebase 通知请求对象中传递 android_channel_id 属性。
{
"notification": {
"body": "this is testing notification",
"title": "My App",
"android_channel_id": "cnid"
},
"to": "token"
}
