Android模拟器强制关闭

-2

我的Android模拟器强制每次我尝试运行它时都会退出程序。我不知道为什么，请帮助我！Android模拟器强制关闭

public class AsteroidsToo extends Activity { 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    new AsteroidWorld(3).bigBang(this); 
    }

}

这里是logcat的错误：

这里是代码为我的构造函数：

/**Represents the World*/ 
class AsteroidWorld extends VoidWorld{ 
    Ship sh; 
    ArrayList<Bullet> b; 
    ArrayList<Asteroids> a; 
    int score; 
    int HighScore; 
    State state; 
    int lives; 
    double timer; 

    public AsteroidWorld(int lives) { 
     super(); 
     this.sh = new Ship(300.0,300.0,0.0,0.0,90.0); 
     this.b = new ArrayList<Bullet>(); 
     this.a = new ArrayList<Asteroids>(); 
     this.score = 0; 
     this.HighScore = 0; 
     this.timer = 3.0; 
     this.state = new Lose(); 
     this.lives = lives;

我也得到一个错误说：

[2011-07-02 20时08分08秒 - 模拟器] 2011-07-02 20：08：08.156 模拟器[14734：903]警告一次：此应用，或者其使用库，是使用NSQuickDrawView，已弃用。应用程序应停止使用的QuickDraw，并转移到石英

这里是我的船的构造

/**Represents the Ship in the game*/ 
class Ship extends FloatObject{ 
Image SpaceShip = new FromFile("spaceship.png"); 
double angle; 
double speed = 2;

如果您让代码更具可读性，即修复代码标记，它确实会帮助我们。 – ambagesia

显示LogCat输出... –

似乎你在AstroidWorld构造函数中有一个NPE，请粘贴相关代码。 – MByD

我的猜测是，在船舶的构造函数，你没有显示，该线在哪里你创建一个FromFile的新实例，你将一个空值传递给FromFile的构造函数。 FromFile的构造函数需要一个String。你甚至可能试图向它传递一个字符串，但无论它到达那里可能实际上是空的。

FromFile的构造函数将值放入HashTable中，并且该值为null，而不是它所期望的值。这就是我无法看到这里所需的一切。

我在哪里可以将.png文件放入项目中？我编辑了这篇文章，以便您可以看到我的造船构造函数。 –
