Google play game has stopped after update score to leaderboard

问题

When I update my score to the leaderboard, and then I open the leaderboard, Google play game has stopped. Can anyone help me with this?

I update the score with this code:

Games.Leaderboards.submitScore(myclient, 
                    getString(R.string.number_guesses_leaderboard),  
                    HighScore); 

I use this to open the leaderboard:

startActivityForResult(Games.Leaderboards.getLeaderboardIntent(
                myclient,getString(R.string.number_guesses_leaderboard)), 
                    0);
