java - 当我向排行榜 android 提交分数时应用程序崩溃

Question

我有一个已发布并集成 Android 排行榜的应用程序，但是当我与另一个用户(未在 Playstore 仪表板中添加为测试者的用户)玩游戏时，当我尝试提交分数时，该应用程序崩溃了。该应用程序已经发布，据我所知它应该可以工作!？!有人能告诉我问题出在哪里吗？

这是我的代码:

private void submitScore(final int points) {
        if (getApiClient().isConnected()) {
            Log.d("--", "submiting score " + points);
            PendingResult<Leaderboards.LoadPlayerScoreResult> result = Games.Leaderboards
                    .loadCurrentPlayerLeaderboardScore(getApiClient(),
                            getString(R.string.poeni_tabela),
                            LeaderboardVariant.TIME_SPAN_ALL_TIME,
                            LeaderboardVariant.COLLECTION_PUBLIC);
            result.setResultCallback(new ResultCallback<Leaderboards.LoadPlayerScoreResult>() {
                @Override
                public void onResult(
                        Leaderboards.LoadPlayerScoreResult loadPlayerScoreResult) {
                    Games.Leaderboards.submitScore(getApiClient(),
                            getString(R.string.poeni_tabela),
                            loadPlayerScoreResult.getScore().getRawScore()
                                    + points);
                }
            });
        }
    }

这是日志:

java.lang.NullPointerException

行com.myapp.QuizActivity$9.onResult(QuizActivity.java:611)是这样的代码:

Games.Leaderboards.submitScore(getApiClient(),
                                getString(R.string.poeni_tabela),
                                loadPlayerScoreResult.getScore().getRawScore()
                                        + points);

Answer 1

还有更多的可能性:

Games.Leaderboards is null
loadPlayerScoreResult is null
loadPlayerScoreResult.getScore() is null
loadPlayerScoreResult.getScore().getRawScore() is null

使用调试器来找出发生了什么。
