Java 内存不足异常

我是android新手。我正在做sd卡的图像列表。下面的代码告诉我错误“614416字节分配的内存不足”

类别：

class AsyncImageLoaderv  {
    int width;
    int height;
    float aspectRatio;
    int newWidth;
    int newHeight;

    public Bitmap loadDrawable(final String imageUrl,
            final ImageCallback imageCallback) {
        final Handler handler = new Handler() {
            @Override
            public void handleMessage(Message message) {
                imageCallback.imageLoaded((Bitmap) message.obj, imageUrl);
            }
        };
        new Thread() {
            @Override
            public void run() {
                try {
                    Log.d("ur", imageUrl);
                    Bitmap drawable = BitmapFactory.decodeFile(imageUrl);
                    width = drawable.getWidth();
                    height = drawable.getWidth();
                    aspectRatio = (float) width / (float) height;
                    newWidth = 98;
                    newHeight = (int) (98 / aspectRatio);
                    Bitmap.createScaledBitmap(drawable, newWidth, newHeight,
                            true);
                    Message message = handler.obtainMessage(0, drawable);
                    handler.sendMessage(message);
                    //this.sleep(1000);

                } catch (Exception e) {
                    Log.e("thread stellent", e.toString());
                }
            }
        }.start();
        return null;
    }

    public interface ImageCallback {
        public void imageLoaded(Bitmap imageBitmap, String imageUrl);
    }
}

正如我在该问题中回答的那样：

位图无法保存重量级图片。阅读这篇文章，可以减小图像的大小。

检查图像是否沉重……此错误表明您正在尝试加载沉重的图像。您正在将图像加载到内存中，然后缩放图像。您应该使用采样中的

inSampleSize

对其进行缩放。有许多重复的问题显示了如何解决这个问题。和android文档。

class AsyncImageLoaderv  {
    int width;
    int height;
    float aspectRatio;
    int newWidth;
    int newHeight;

    public Bitmap loadDrawable(final String imageUrl,
            final ImageCallback imageCallback) {
        final Handler handler = new Handler() {
            @Override
            public void handleMessage(Message message) {
                imageCallback.imageLoaded((Bitmap) message.obj, imageUrl);
            }
        };
        new Thread() {
            @Override
            public void run() {
                try {
                    Log.d("ur", imageUrl);
                    Bitmap drawable = BitmapFactory.decodeFile(imageUrl);
                    width = drawable.getWidth();
                    height = drawable.getWidth();
                    aspectRatio = (float) width / (float) height;
                    newWidth = 98;
                    newHeight = (int) (98 / aspectRatio);
                    Bitmap.createScaledBitmap(drawable, newWidth, newHeight,

    }

    public interface ImageCallback {
        public void imageLoaded(Bitmap imageBitmap, String imageUrl);
    }
