我使用Parse作为后端制作了一个应用程序.我能够收到通知,但是当我点击它时,应用程序崩溃了.

这是java和XML文件.

我在我的应用程序中有这个功能来制作排行榜.执行时,它永远不会到达for循环,我无法更新我的排行榜.是否有更好的实施方案？

public void updateLeaderboard(final Context context) {
        Log.d("Leaderboard ", "Updating");
        ParseQuery<ParseObject> query = ParseQuery.getQuery(KEY_USER_CLASS);
        query.addDescendingOrder(KEY_LAST_LEVEL);
        query.addAscendingOrder(KEY_CROSSED_AT);
        query.whereNotEqualTo(KEY_ADMIN, true);
        query.whereEqualTo(KEY_EMAIL_VERFIFIED, true);
        query.findInBackground(new FindCallback<ParseObject>() {

            @Override
            public void done(List<ParseObject> users, ParseException e) {
                Log.d("Leaderboard ", "done() caled");
                if (e == null) {
                    Log.d("Leaderboard ", "inside if");

                    for (int i = 0; i < users.size(); i++) {
                        ParseObject user = users.get(i);
                        Log.d("Leaderboard ",
                                "Updating user " + String.valueOf(i + 1));
                        user.put(KEY_RANK, i + 1);
