Question

我不明白为什么我在创建这样的pendingIntent实例时会出现NullPointerException：

 @Override
protected void onActivityResult(int requestCode, int resultCode, Intent intent) {


    if(requestCode == REQUEST_CODE && resultCode == RESULT_OK) {

        Alarm alarm = (Alarm) intent.getSerializableExtra(AlarmAdapter.ALARM_INSTANCE);
        int position = intent.getIntExtra(AlarmAdapter.ITEM_POSITION_ADAPTER, 0);

        PendingIntent pendingIntent = PendingIntent.getActivity(getApplicationContext(), position, intentListAlarmActivityToWakeUpActivity, 0);

        //setAlarm(alarm.getHourOfAlarm(), alarm.getMinutesOfAlarm(), position);
        mListOfAlarm.get(position).setData(alarm);
        mAlarmAdapter.notifyDataSetChanged();

    }
}

PendingIntent.getActivity（...）返回null ... 以下是Android Studio中的堆栈跟踪：
