Android模擬器強制關閉

-2

我的Android模擬器強制每次我嘗試運行它時都會退出程序。我不知道爲什麼，請幫助我！Android模擬器強制關閉

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

}

這裏是logcat的錯誤：

這裏是代碼爲我的構造函數：

/**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;

我也得到一個錯誤說：

[2011-07-02 20時08分08秒 - 模擬器] 2011-07-02 20：08：08.156 模擬器[14734：903]警告一次：此應用，或者其使用庫，是使用NSQuickDrawView，已棄用。應用程序應停止使用的QuickDraw，並轉移到石英

這裏是我的船的構造

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

如果您讓代碼更具可讀性，即修復代碼標記，它確實會幫助我們。 – ambagesia

顯示LogCat輸出... –

似乎你在AstroidWorld構造函數中有一個NPE，請粘貼相關代碼。 – MByD

我的猜測是，在船舶的構造函數，你沒有顯示，該線在哪裏你創建一個FromFile的新實例，你將一個空值傳遞給FromFile的構造函數。 FromFile的構造函數需要一個String。你甚至可能試圖向它傳遞一個字符串，但無論它到達那裏可能實際上是空的。

FromFile的構造函數將值放入HashTable中，並且該值爲null，而不是它所期望的值。這就是我無法看到這裏所需的一切。

我在哪裏可以將.png文件放入項目中？我編輯了這篇文章，以便您可以看到我的造船構造函數。 –
