在使用AlarmManager构造intent，设置定时广播闹钟，在时间到达后，广播接收到的bundle为空

• 开发过程中，使用AlarmManager时遇到了一个问题至今网上没有明确原因：

  构造intent，设置定时广播闹钟，在时间到达后，广播接收到的bundle为空

    private void setMessageEndTrigger(MessageRecommend requireMessage) {
        Intent startMessage = new Intent(MESSAGE_START_ACTION);
        Bundle bundle = new Bundle();
        bundle.putSerializable(MESSAGE, requireMessage);
        startMessage.putExtras(bundle);
        PendingIntent intent = PendingIntent.getBroadcast(mContext,
                MESSAGE_WHAT, startMessage, PendingIntent.FLAG_CANCEL_CURRENT);
        if (requireMessage == null) {
            LogUtil.debug(TAG + "TimingMessage end is cancel");
            mAlarmManager.cancel(intent);
            return;
        }
        long endTime = TimeParseUtil.parseLong(requireMessage.getEndTime());
        mAlarmManager.setExact(AlarmManager.RTC_WAKEUP, endTime, intent);
    }

    private void checkStartMessage(Intent intent) {
        // rec是空的
        MessageRecommend rec = (MessageRecommend) intent.getExtras().get(MESSAGE);
        if (!mAreaManager.checkArea(rec.getProvinceName(), rec.getCityName())) {
            LogUtil.warning(TAG + "the city is change");
            return;
        }
        if (!mAccountManager.getAccountId().equals(rec.getAccount())) {
            LogUtil.warning(TAG + "the Account is change");
            return;
        }
        sendOperatorMessage(rec);
    }

• 第一种解决：将bundle使用putExtra方法设置Key和Value，放弃putExtras方法直接put进bundle

    private void setMessageStartTrigger(MessageRecommend requireMessage) {
        Intent startMessage = new Intent(MESSAGE_START_ACTION);
        Bundle bundle = new Bundle();
        bundle.putSerializable(MESSAGE, requireMessage);
        startMessage.putExtra(MESSAGE, bundle);
        PendingIntent intent = PendingIntent.getBroadcast(mContext,
                MESSAGE_WHAT, startMessage, PendingIntent.FLAG_CANCEL_CURRENT);
        if (requireMessage == null) {
            LogUtil.debug(TAG + "TimingMessage start is cancel");
            mAlarmManager.cancel(intent);
            return;
        }
        long startTime = TimeParseUtil.parseLong(requireMessage.getStartTime());
        LogUtil.debug(TAG + "TimingMessage start time" + startTime);
        mAlarmManager.setExact(AlarmManager.RTC_WAKEUP, startTime, intent);
    }

• 广播接收时使用先去调用getBundleExtra方法获取bundle，在通过bundle的getSerializable方法获取对象

    private void checkStartMessage(Intent intent) {
        MessageRecommend rec = (MessageRecommend) intent.
                getBundleExtra(MESSAGE).getSerializable(MESSAGE);
        if (rec == null) {
            LogUtil.debug(TAG + "start time Message is null ");
            return;
        }
        LogUtil.debug(TAG + "start time Message: " + rec.toString());
//        if (!mAreaManager.checkArea(rec.getProvinceName(), rec.getCityName())) {
//            LogUtil.warning(TAG + "the city is change");
//            return;
//        }
        if (!mAccountManager.getAccountId().equals(rec.getAccount())) {
            LogUtil.warning(TAG + "the Account is change");
            return;
        }
        sendOperatorMessage(rec);
    }

• 第二种解决：

  可以把传递的参数都转成String传，对象也通过Json转成字符串来传。
