Setting notification sound volume

I am using a NotificationChannel to define my app's notification. I set it's sound with the following code :

AudioAttributes.Builder constructeurAttributsAudio=new AudioAttributes.Builder();
constructeurAttributsAudio.setUsage(AudioAttributes.USAGE_NOTIFICATION_EVENT);
canalNotification.setSound(Uri.parse(ContentResolver.SCHEME_ANDROID_RESOURCE    + "://" + contexte.getPackageName() + "/raw/cloche"),constructeurAttributsAudio.build());

When the notification appears, the sound is correctly emitted, but it's volume is set at the maximum and doesn't take into account the sound level set for notifications by the user. Does anyone know how I can have my app set the notification sound level to the value choosen by the user?

Edit #1 : if I copy the code to execute it in the app's body (triggered by a Button click) instead of in the onReceive method of my BroadcastReceiver, the notification sound is correctly emitted at the sound level chosen by the user for notifications.

Edit #2 : strangely, the notification sound level is correct when the app is executed on the emulator! Could the reason be a parameter in the phone's configuration? (They both run under Android 9).

Solution

  • Uninstalling and reinstalling the app solved the problem!
