Notification sound from URI parse does not work

问题:

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;
 }

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.

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.

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

package com.example.memoryGuide;

Any ideas why the sound never plays?

回答1:

use

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

Note one thing.

String android.content.ContextWrapper.getPackageName()

returns the package name of your android aplication. And

package com.example.memoryGuide;

shows the package name of your source package name.

If this one work for you. Please vote up..........

Just put your sound file in Res\raw\siren.mp3 folder ::

Then put this code..This will definitely work for you.

For Custom Sound ::

 notification.sound = Uri.parse("android.resource://"
            + context.getPackageName() + "/" + R.raw.siren);

For Default Sound ::

notification.defaults |= Notification.DEFAULT_SOUND;

For Custom Vibrate ::

  long[] vibrate = { 0, 100, 200, 300 };
     notification.vibrate = vibrate;

For Default Vibrate ::

notification.defaults |= Notification.DEFAULT_VIBRATE;

I was having a similar problem while testing on API 23. While I do not know the cause of the problem, I did manage to find a workaround that got the job done.

In one of Google's examples, a notification is constructed thusly:

// Get a notification builder that's compatible with platform versions >= 4
NotificationCompat.Builder builder = new NotificationCompat.Builder(this);

// Define the notification settings.
builder.setSmallIcon(R.drawable.ic_launcher)
        // In a real app, you may want to use a library like Volley
        // to decode the Bitmap.
        .setLargeIcon(BitmapFactory.decodeResource(getResources(),
                R.drawable.ic_launcher))
        .setColor(Color.RED)
        .setContentTitle(notificationDetails)
        .setContentText(getString(R.string.geofence_transition_notification_text))
        .setContentIntent(notificationPendingIntent);

// Dismiss notification once the user touches it.
builder.setAutoCancel(true);

// Get an instance of the Notification manager
NotificationManager mNotificationManager =
        (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

// Issue the notification
mNotificationManager.notify(0, builder.build());

Notice the class NotificationCompat.Builder. For some reason which is beyond me, this did not play any sound other than the default one. In other words, only this worked:

// Define sound URI
Uri soundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION); // Default
...
builder.setSound(soundUri); //Set the sound to play

But this didn't:

Uri soundUri = Uri.parse(ContentResolver.SCHEME_ANDROID_RESOURCE + "://" + 
                           getPackageName() + "/" + R.raw.name_of_sound);

After simply replacing the builder class with Notification.Builder (available for API >= 11) the "this didn't" section above started working as expected.

Conclusion: use this if you're willing to sacrifice (or are not interested in) compatibility with API < 11.
