嗨,我刚刚在android中尝试使用parse Api.并在logcat中获得以下错误.

这是我的代码:

 ParseQuery<User> query = ParseQuery.getQuery("User");
            query.whereEqualTo("phone", phone);

            try {
                List<User> all = query.find();
                Log.v("Size of users are",all.size()+"");
                if (all.size() != 0) {
                    foundUser = true;
                    a = all.get(0);
                }
            } catch (ParseException e) {
                e.printStackTrace();
            }

这是我的logcat中的错误:
