什么是我的logcat中的错误？

Question

我现在几乎完成了我的游戏,但今天我遇到了一个真正令人讨厌的问题.当我开始游戏并等待几秒钟时,程序会自动关闭.而且我没有表现出来.

这是我的logcat显示的内容:

遗憾的是我没有代码要分享,因为我不知道程序崩溃了.

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();
}

Answer 1

你某处有内存泄漏.请参阅开发人员文档中的此博客文章,以获取可用于跟踪它的工具.另请参阅此博客文章,了解有关避免在Android应用程序中泄漏内存的编程提示.

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. 

看来您的游戏使用了两个多的内存（或）内存泄漏。您可能需要使用本讨论中介绍的一些技术记录过程的内存使用情况，然后从那里获取信息。
