Question

我有自己的BroadcastReceiver，它发送推送通知。我需要在我的应用程序中为通知提供声音。这是我现在的代码：

public class TimeReceiver extends BroadcastReceiver {

   @Override
   public void onReceive(Context context, Intent intent) {
      Log.d("tag", "onReceive");
      sendNotification(context);;
}

   private void sendNotification(Context context) {
      NotificationCompat.Builder builder = createBuilder(context);
      Notification notification = builder.build();
      notification.defaults |= Notification.DEFAULT_SOUND;
      getNotificationManager(context).notify(1, builder.build());
   }

   private NotificationManager getNotificationManager(Context context) {
      return (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
   }

   private NotificationCompat.Builder createBuilder(Context context) {
      NotificationCompat.Builder builder = new NotificationCompat.Builder(context)
            .setSmallIcon(R.drawable.ic_keyboard_arrow_right_black_24dp)
            .setContentTitle(context.getResources().getString(R.string.title))
            .setContentText(context.getResources().getString(R.string.content))
            .setAutoCancel(true);
      return builder;
   }
}

接收器工作并发送通知，但没有声音。我也尝试过NotificationCompat.Builder的setSound（uri），但它也没用。我做错了什么？

更改此行 -

getNotificationManager(context).notify(1, builder.build())

到 -

getNotificationManager(context).notify(1, notification).

您正在传递旧的通知对象

Android通知声音无效
