AlarmManager只播放默认铃声

Question

我正在使用AlarmManager和PendentIntent创建一个警报。警报起作用，并在正确的时间触发。不幸的是，无论我选择哪种铃声，它总是播放默认的铃声。这是我的代码：

public void setAlarm() {
    Cursor cursor = dataBaseHelper.showSpecificTableData(DBFields.TABLE_OF_ALARMS, DBFields.ALARM_STATUS, "On");
    cursor.moveToLast();

    String alpha[] = cursor.getString(cursor.getColumnIndex(DBFields.ALARM_TIME)).split(":");

    calendar.set(Calendar.HOUR_OF_DAY, Integer.parseInt(alpha[0]));
    calendar.set(Calendar.MINUTE, Integer.parseInt(alpha[1]));
    calendar.set(Calendar.SECOND, 0);

    Intent intent = new Intent(AddAlarm.this, AlarmReceiver.class);
    intent.putExtra("AlarmTone", cursor.getString(cursor.getColumnIndex(DBFields.ALARM_TONE)));
    intent.putExtra("AlarmId", cursor.getInt(cursor.getColumnIndex(DBFields.ALARM_ID)));
    intent.putExtra("AlarmName", cursor.getString(cursor.getColumnIndex(DBFields.ALARM_NAME)));
    intent.putExtra("AlarmTime", cursor.getString(cursor.getColumnIndex(DBFields.ALARM_TIME)));
    pendingIntent = PendingIntent.getBroadcast(getApplicationContext(),
            100,
            intent,
            FLAG_UPDATE_CURRENT);

    alarmManager.setExact(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent);
}

我已经使用了调试器，并且知道正确的铃声被作为“ AlarmTone”额外的。

知道为什么选定的铃声不玩
