嗨，我想在我正在开发的游戏中构建 Google+ 游戏 API。但是我有一个问题，我不能直接向 API 发送分数，因为游戏没有在 Activity 中运行。所以我想将分数发送到外部类中的函数，所以我尝试了这段代码：
private void updateGameOver(List<TouchEvent> touchEvents) {
int len = touchEvents.size();
for (int i = 0; i < len; i++) {
TouchEvent event = touchEvents.get(i);
Leaboarder lea = new Leaboarder();
lea.sendScore(Counter.getScore());
nullify();
game.setScreen(new MainMenuScreen(game));
return;
}
}
}
但我收到以下错误：
06-27 21:58:30.746: W/dalvikvm(5701): threadid=13: thread exiting with uncaught exception (group=0x40b88300)

我的Leaboarder类：
public class Leaboarder extends Activity implements GameHelper.GameHelperListener {
protected GameHelper mHelper;
protected int mRequestedClients = GameHelper.CLIENT_GAMES;
public static int score = 0;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
int score = getIntent().getIntExtra("score", 0);
sendScore(score);
}
public void sendScore(int score) {
mHelper = new GameHelper(Leaboarder.this);
mHelper.setup(Leaboarder.this, mRequestedClients);
GamesClient mGamesClient = mHelper.getGamesClient();
if (mHelper.isSignedIn()) {
mGamesClient.submitScore("", score);
}
else {
Toast.makeText(getBaseContext(), "Not Loggin - Score saved offline.", Toast.LENGTH_LONG).show();
SharedPreferences pref = getSharedPreferences("offlineScore", 0);
int scoreOLD = pref.getInt("topscore", 0);
if (score > scoreOLD){
pref.edit().putInt("topscore", score).apply();
}
}
}
}
我的问题是如何解决这个问题？
