颤振的本地通知自定义声音不起作用(路径问题) [英] Flutter local notification custom sound doesn't work (path issue)

问题描述

var androidPlatformChannelSpecifics =
                    new AndroidNotificationDetails(
                        "$id",
                        not.columnValue + not.deveui,
                        not.columnValue + not.deveui,
                        sound: "@raw/alarm",
                        importance: Importance.Max,
                        priority: Priority.High);

实际上，它仍然会使用默认的系统声音.

如果放入@raw/alarm.mp3，则会出现以下异常:Unhandled Exception: PlatformException(INVALID_SOUND, The resource %s could not be found. Please make sure it has been added as a raw resource to your Android head project., null)

Actually it still sounds with the default system sound.

If I put @raw/alarm.mp3, I got the following exception: Unhandled Exception: PlatformException(INVALID_SOUND, The resource %s could not be found. Please make sure it has been added as a raw resource to your Android head project., null)

注意:声音:RawResourceAndroidNotificationSound('alarm')，已解决

note : sound: RawResourceAndroidNotificationSound('alarm'), solved

推荐答案

您不需要将'@ raw/'放置到路径中，插件已经在从中获取声音(根据插件来源:FlutterLocalNotificationsPlugin.java函数retrieveSoundResourceUri )，请删除它.

You don't need to put '@raw/' to path, plugin is already taking sounds from it (according to plugin source: FlutterLocalNotificationsPlugin.java function retrieveSoundResourceUri) so remove it.

还请检查声音文件是否包含在内部版本中.通过在原始文件夹中创建具有以下内容的keep.xml

also check that sound file is included in build, ex. by creating keep.xml in raw folder with following content

<?xml version="1.0" encoding="utf-8"?>
<resources xmlns:tools="http://schemas.android.com/tools"
    tools:keep="@drawable/*,@raw/alarm" />
