SimpleBaseGameActivity从另一个开始时,我的应用程序出现问题SimpleBaseGameActivity.代码是:
Intent intent = new Intent(MainMenuActivity.this, PacManActivity.class);
intent.putExtra(INTENT_LEVEL_NUMBER, levelNumber);
intent.putExtra(INTENT_WORLD_NUMBER, worldNumber);
startActivity(intent);
它运行良好,但当它加载另一个Activity(PacManActivity)时会抛出异常:
FATAL EXCEPTION: main
java.lang.NullPointerException
at org.andengine.ui.activity.BaseGameActivity.onResumeGame(BaseGameActivity.java:220)

我甚onResumeGame()至没有实现方法,如果我PacManActivity默认启动(配置Manifest.xml),它运行没有任何错误.
有人可以帮我解决这个问题.
