Android notification setSound is not working

Question

In my hybrid Cordova Android app targeting API 23+ I want to use a custom sound for notifications. To that end I have done the following

• In plugin.xml file for the single custom plugin I use in the app I declare <resource-file src="src/android/res/unysound.mp3" target="res/raw/mysound.mp3" />'.

Opening the APK as a zip archive I see that the mp3 file has in fact ended up in `res/raw/mysound.mp3'. - When building the notification I do the following

    Notification notification = new Notification.Builder(context)     .setDefaults(0) //turns off ALL defaults     .setVibrate(vibrate)  /sets to vibrate     ....     .setSound(uri).build(); 

where

Uri uri = Uri.parse("android.resource://" + ctxt.getPackageName() + "/raw/mysound.mp3"); 

This appears to be the recipe indicated in a number of articles I find on a spot of googling and even in other threads on SO. And yet, when I issue a notification I do not hear the expected sound. What might I be doing wrong?

The answer below does not help since in the context of my hybrid Cordova app with a custom plugin attempting to build the APK throws up an error along the lines of class R not known/found...

Answer 1

below code will help you:

 String CHANNEL_ID="1234";      Uri soundUri = Uri.parse(ContentResolver.SCHEME_ANDROID_RESOURCE + "://"+ getApplicationContext().getPackageName() + "/" + R.raw.mysound);     NotificationManager mNotificationManager = (NotificationManager) getApplicationContext().getSystemService(Context.NOTIFICATION_SERVICE);         //For API 26+ you need to put some additional code like below:     NotificationChannel mChannel;         if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {                 mChannel = new NotificationChannel(CHANNEL_ID, Utils.CHANNEL_NAME, NotificationManager.IMPORTANCE_HIGH);                 mChannel.setLightColor(Color.GRAY);                 mChannel.enableLights(true);                 mChannel.setDescription(Utils.CHANNEL_SIREN_DESCRIPTION);                 AudioAttributes audioAttributes = new AudioAttributes.Builder()                         .setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION)                         .setUsage(AudioAttributes.USAGE_NOTIFICATION)                         .build();                 mChannel.setSound(soundUri, audioAttributes);                      if (mNotificationManager != null) {                     mNotificationManager.createNotificationChannel( mChannel );                 }         }     //General code:      NotificationCompat.Builder status = new NotificationCompat.Builder(getApplicationContext(),CHANNEL_ID);                                status.setAutoCancel(true)                                 .setWhen(System.currentTimeMillis())                                 .setSmallIcon(R.drawable.logo)                                 //.setOnlyAlertOnce(true)                                 .setContentTitle(getString(R.string.app_name))                                 .setContentText(messageBody)                                 .setVibrate(new long[]{0, 500, 1000})                                 .setDefaults(Notification.DEFAULT_LIGHTS )                                 .setSound(Uri.parse(ContentResolver.SCHEME_ANDROID_RESOURCE+ "://" +mContext.getPackageName()+"/"+R.raw.apple_ring))                                 .setContentIntent(pendingIntent)                                 .setContent(views);                                                  mNotificationManager.notify(major_id, status.build()); 

where mysound is my ringtone which is put under res/raw folder.

Note: you have to only put name of ringtone without extension like raw/mysound

Note: In Android Oreo you must change your channel ID to changes take effect. And before Oreo version, using ".setDefaults()" seens prevent custom sound to play.

Answer 2

1. Try clearing data (or fresh install)
2. Trying this again

The settings are set the first time you create the channel and then not modified unless you do it manually by fresh install or clearing data.
