Android奇怪的ArithmeticException：除以零

Question

我在我的活动中的一些设备上得到了ArithmeticException（除以0）。这是我得到的堆栈跟踪

java.lang.ArithmeticException: divide by zero

我的包名是 com.afre.quirky ，我收到错误的活动是 GameActivity

奇怪的是，我在极少数设备上遇到此错误（HTC Desire 700就是其中之一）而且，堆栈跟踪并未显示GameActivity中的确切行，其中I＆ ＃39;我得到了错误。除此之外，我在该活动中没有任何除法任务，其中除数可以为零。

这是我的GameActivity代码

public class GameActivity extends AppCompatActivity {
    private GameView gameView;

    public static int SCREEN_HEIGHT;
    public static int SCREEN_WIDTH;

    ImageView image;
    ImageView demo;
    ImageView loading;
    TextView loadText;

    RelativeLayout mLayout;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_game);

        mLayout = (RelativeLayout) findViewById(R.id.gameLayout);
        image = (ImageView) findViewById(R.id.color);
        demo = (ImageView) findViewById(R.id.demo);
        loading = (ImageView) findViewById(R.id.loading);
        loadText = (TextView) findViewById(R.id.loadText);

        setWidthAndHeight();
    }

    void setWidthAndHeight() {

        Display display = getWindowManager().getDefaultDisplay();
        DisplayMetrics size = new DisplayMetrics();

        int navBarHeight = 0;
        Resources resources = getResources();
        int resourceId = resources.getIdentifier("navigation_bar_height", "dimen", "android");
        if (resourceId > 0) {
            navBarHeight = resources.getDimensionPixelSize(resourceId);
        }

        boolean hasPhysicalHomeKey = KeyCharacterMap.deviceHasKey(KeyEvent.KEYCODE_HOME);

        if(Build.VERSION.SDK_INT >= 17) {
            display.getRealMetrics(size);
            SCREEN_WIDTH = size.widthPixels;
            SCREEN_HEIGHT = size.heightPixels;
        }
        else if(hasPhysicalHomeKey) {
            SCREEN_WIDTH = new DisplayMetrics().widthPixels;
            SCREEN_HEIGHT = new DisplayMetrics().heightPixels;
        }
        else {
            SCREEN_WIDTH = new DisplayMetrics().widthPixels;
            SCREEN_HEIGHT = new DisplayMetrics().heightPixels + navBarHeight;
        }
    }
}
