我的 logcat 中出现什么错误？

Question

我现在快完成我的游戏了，但是今天我遇到了一个真正烦人的问题。当我启动游戏，只等几秒钟，程序就自动关闭。我对此没有任何解释。

这就是我的 logcat 显示的内容：

不幸的是，我没有代码可以分享，因为我不知道程序是否崩溃。

编辑：绘图代码：

@Override
public void screen(float deltaTime) {
    Graphics g = app.getGraphics();

    g.drawPixmap(Assets.background, 0, 0);

    g.drawPixmap(Assets.facebook, 750, 20);

    g.drawText("SNAKE", 10, 150, Color.BLACK, 150, AndroidGraphics.LEFT,
            null, 0);
    g.drawText("START", g.getWidth() / 2, g.getHeight() - 20, Color.BLACK,
            120, AndroidGraphics.CENTER, startRec, 0);
    g.drawText("HIGHSCORE", 20, 275, Color.BLACK, 50, AndroidGraphics.LEFT,
            highRec, 0);
    g.drawText("MORE APPS", g.getWidth() - 20, 275, Color.BLACK, 50,
            AndroidGraphics.RIGHT, moreRec, 0);
    if (Settings.soundEnabled)
        g.drawPixmap(Assets.buttons, new Rect(0, 0, 100, 100), new Rect(0,
                380, 100, 480));
    else
        g.drawPixmap(Assets.buttons, new Rect(100, 0, 200, 100), new Rect(
                0, 380, 100, 480));
}

drawText方法：

@Override
public void drawText(String text, int x, int y, int color, int size,
        int position, Rect bounds, int rotation) {
    if (position == LEFT)
        paint.setTextAlign(Paint.Align.LEFT);
    else if (position == CENTER)
        paint.setTextAlign(Paint.Align.CENTER);
    else if (position == RIGHT)
        paint.setTextAlign(Paint.Align.RIGHT);
    else
        return;
    paint.setColor(color);
    Typeface typeface = Typeface.createFromAsset(assets, "typewrite.TTF");
    paint.setTypeface(typeface);
    paint.setTextSize(size);
    if (bounds != null) {
        Rect rec = new Rect();
        paint.getTextBounds(text, 0, text.length(), rec);
        bounds.bottom = y;
        bounds.top = y - rec.height();
        if (position == CENTER) {
            bounds.left = x - rec.width() / 2;
            bounds.right = x + rec.width() / 2;
        } else if (position == RIGHT) {
            bounds.left = x - rec.width();
            bounds.right = x;
        } else if (position == LEFT) {
            bounds.left = x;
            bounds.right = x + rec.width();
        } else
            return;
    }
    canvas.save();
    canvas.rotate(rotation, x, y);
    canvas.drawText(text, x, y, paint);
    canvas.restore();
}

你的某个地方有内存泄漏。请参阅开发人员文档中的此博文，了解可以使用的工具追踪它。另请参阅这篇博文，了解避免 Android 应用程序内存泄漏的编程技巧。

Answer 2

~ Channel is unrecoverably broken and will be disposed!  

01-22 16:21:21.443: INFO/ActivityManager(73): Low Memory: No more background processes. 

看起来你的游戏使用了两次内存（或）内存泄漏。您可能需要使用 这个讨论并从那里获取。

通过单步调试，我得到了详细错误：您必须在...中提供layout_height属性。它确实适合我的情况。
