URI解析发出的通知声音不起作用 [英] Notification sound from URI parse does not work

问题描述

关于Stackoverflow至少有7个与此相关的问题，我已经多次尝试了每个建议和解决方案，但没有一个起作用.这是我最近的尝试:

There are at least 7 questions on Stackoverflow related to this, I have tried every single suggestion and solution multiple times and none of them have worked. Here is my latest attempt:

private Notification createNotification() {
       Notification notification = new Notification();


       if(notifyImage=="food")
         {
           notification.icon = R.drawable.food;
           notification.sound = Uri.parse(ContentResolver.SCHEME_ANDROID_RESOURCE + "://com.example.memoryGuide/raw/start");
         }
       else
       {
           notification.icon = R.drawable.bar; 
           notification.sound = Uri.parse(ContentResolver.SCHEME_ANDROID_RESOURCE + "://com.example.memoryGuide/raw/start");
       }


       notification.when = System.currentTimeMillis();
       notification.flags |= Notification.FLAG_AUTO_CANCEL;
       notification.flags |= Notification.FLAG_SHOW_LIGHTS;
       notification.defaults |= Notification.DEFAULT_VIBRATE;
       notification.defaults |= Notification.DEFAULT_LIGHTS; 
       notification.ledARGB = Color.WHITE;
       notification.ledOnMS = 1500;
       notification.ledOffMS = 1500;
       return notification;
 }

您可以看到我尝试过两次都无法使用的声音，但是图标可以正常工作.我不知道是否缺少任何东西才能使它正常工作，但是我正在使用的所有代码都在我的帖子中.

You can see the two times I try and use a sound which never works, but the icons work perfectly. I do not know if I am missing anything in order to get this to work, but all of the code I am using is in my post.

我的声音文件在res/raw/start.mp3中，按一下按钮就可以使声音起作用，所以声音很好.

My sound file is in res/raw/start.mp3, I can get this sound to work when pressing a button, so the sound is fine.

我认为程序包名称正确，我的应用程序位于每个类的顶部:

I think the package name is right, my application at has this at the top of each class:

package com.example.memoryGuide;

有什么想法为什么声音永远不会播放?

Any ideas why the sound never plays?

推荐答案

使用

notification.sound = Uri.parse(ContentResolver.SCHEME_ANDROID_RESOURCE
        + "://" + getPackageName() + "/raw/start");

请注意一件事.

字符串android.content.ContextWrapper.getPackageName()

返回您的Android应用程序的包名称.还有

returns the package name of your android aplication. And

打包com.example.memoryGuide;

package com.example.memoryGuide;

显示源软件包名称的软件包名称.

shows the package name of your source package name.
