App crashes when I submit score to leaderboard android

I have an app that I have published and integrated android leaderboard, but when I play the game with another user(user not added as tester in the playstore dashboard) the app is crashing when I try to submit the score. The app is already published and as I know it should work!?! Can someone tell me what can the problem be?

Here is my code:

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);
                }
            });
        }
    }

And here is the log:

java.lang.NullPointerException
at com.myapp.QuizActivity$9.onResult(QuizActivity.java:611)

The line com.myapp.QuizActivity$9.onResult(QuizActivity.java:611) is this code: 

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

OK, I've found the answer to my question thanks to @Jens. Seems like loadPlayerScoreResult.getScore().getRawScore() is null. This I suppose is because the player haven't submited any score yet so in that case you just add the initial score, and next time if its not null - and it should not be, you can sum old points with the new ones.

here is the code that im using now in the submitScore method above:

if (loadPlayerScoreResult.getScore() != null) {
                        Games.Leaderboards.submitScore(getApiClient(),
                                getString(R.string.poeni_tabela),
                                loadPlayerScoreResult.getScore().getRawScore()
                                        + points);
                    } else {
                        Games.Leaderboards.submitScore(getApiClient(),
                                getString(R.string.poeni_tabela), points);
                    }

There are more possibilities:

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

Use a debugger to find out what is happend.
