Question

我在android上遇到以下错误：

Out of memory: Heap Size=41159KB, Allocated=33002KB, Limit=49152KB

当我尝试调用构造函数的BitmapFactory.decodeResource方法时：

public class Background {

private Bitmap bitmap;

public Background(Resources resources) {
    bitmap = BitmapFactory.decodeResource(resources, R.drawable.ground);
}

public void render(Canvas canvas, int WIDTH, int HEIGHT) {

    for(int x = 0; x < WIDTH; x += bitmap.getWidth())
        for(int y = 0; y < HEIGHT; y += bitmap.getHeight())
            canvas.drawBitmap(bitmap, x, y, null);

}

}

任何解决方案？

在我尝试这样做之前遇到同样的错误之前：

  socket.on("render", new Emitter.Listener() {
        @Override
        public void call(Object... args) {
            update(args);
            Canvas canvas = getHolder().lockCanvas();
            draw(canvas);
            getHolder().unlockCanvasAndPost(canvas);
        }
    });

使用socket.io我在服务器上创建了渲染循环，向所有客户端套接字发出“render”事件。现在它甚至没有达到应该自我渲染的程度。

所以上面提到了两个问题，任何想法如何解决这个问题？提前谢谢你......

android：largeHeap =“true”只是在10秒后推开这个问题

System.gc（）使它持续更长时间，比如15秒，直到它失败：

虽然我还没有渲染精灵......

在单独的线程中运行渲染循环没有帮助。所以我尽量不画背景和前景但它也失败了。正如我之前所说，当我尝试在服务器上运行渲染循环时，问题似乎出现在Socket.io库中。

如果我将服务器上的FPS更改为等于1，则不会失败!!!

内存不足Socket.IO渲染Android应用程序
