Java 内存不足Socket.IO呈现Android应用程序

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);

}

}

我使用socket.io在服务器上创建了渲染循环，该循环向所有客户端套接字发出“render”事件。现在它甚至还没有达到应该渲染自己的程度

上面提到了两个问题，有没有办法解决？？？ 提前谢谢你

android:largeHeap=“true”只是在10秒后才将这个问题推到一边

gc（）使其持续时间更长，如15秒，直到出现以下故障：

虽然我还没有渲染精灵

编辑3

在单独的线程中运行渲染循环没有帮助。所以我试着不画背景和前景，但也失败了。正如我前面所说的，当我试图在服务器上运行渲染循环时，问题似乎出现在Socket.io库中

若我将服务器上的FPS更改为等于1，它不会失败

在它看来，这是一个巨大的循环语句，您正试图实现。你想要达到的目标是什么？首先，canvas.drawBitmap（位图，x，y，null）；可能被调用的次数太多了。我试图在5000x5000世界中绘制500x500图像两次，但如果我每秒调用render 30次，则socket.io库似乎存在问题。嗯？这是在主线程上发生的还是在单独的线程中运行？Main:D我应该在单独的线程上运行它吗？这会解决问题吗？？？如果是的话，那么我应该非常感谢你…在一个单独的线程上运行可能会有所帮助，但问题似乎是你试图做太多来实现你的目标。特别是两张图片。你到底想画什么？
