Question

我只有SDK28模拟器有一个奇怪的问题。在旧版本上一切正常。

借助于前台服务，我正在启动一个通知，该通知应该同时具有声音和振动。我的问题是28SDK仿真器上没有声音，也没有“振动（根据logcat）”

private void setNotification(final Context context, long ID){

    NotificationCompat.Builder builder = new NotificationCompat.Builder(context);

    builder.setPriority(NotificationCompat.PRIORITY_HIGH);
    builder.setContentIntent(pendingIntent);
    builder.setAutoCancel(true);
    PendingIntent tmp = PendingIntent.getActivity(context, 0, new Intent(), PendingIntent.FLAG_UPDATE_CURRENT);
    builder.setFullScreenIntent(tmp, true);

    final NotificationManager manager = (NotificationManager) context.getSystemService(NOTIFICATION_SERVICE);
    if(manager != null) {
    String channelName = "ChannelName";
        mChannel = new NotificationChannel(channelName, channelName, NotificationManager.IMPORTANCE_HIGH)  Uri notification = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_ALARM);
                ringtone = RingtoneManager.getRingtone(getApplicationContext(), notification);
                AudioAttributes audioAttributes = new AudioAttributes.Builder()
                        .setFlags(AudioAttributes.USAGE_ALARM)
                        .setUsage(AudioAttributes.USAGE_ALARM)
                        .build();
                mChannel.setSound(notification, audioAttributes);

        long[] vibrationPattern = new long[]{0, 300, 700, 300, 700};
                mChannel.enableVibration(true);
                mChannel.setVibrationPattern(vibrationPattern);

        builder.setChannelId(channelName);
        Notification notification = builder.build();
        startForeground((int) ID, notification);
    }
}

我不能简单地从28SDK仿真器上的扬声器听到声音。另一方面，该振动作为错误记录在logcat上：

1919-11280 / system_process E / VibratorService：vibratorOn命令失败（1）。

在其他模拟器上，振动记录为成功，但显然未在模拟器上显示。

谢谢！

SDK 28仿真器上没有警报声或振动
