Android 使用universalimageloader下载图像时发生java.lang.OutOfMemoryError

我有用于GridView的自定义适配器，其中显示来自服务器的数据， 我成功地显示了数据，但当我多次滚动gridview时，它给了我错误java.lang.OutOfMemoryError，我的logcat错误如下：

对于显示图像，我使用通用图像加载器

ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder(context)
    .build();
    ImageLoader.getInstance().init(config);  


DisplayImageOptions options = new DisplayImageOptions.Builder()
    .showImageOnLoading(R.drawable.ic_stub)
    .showImageForEmptyUri(R.drawable.ic_stub)
    .showImageOnFail(R.drawable.ic_stub)
    .resetViewBeforeLoading(false)
    .delayBeforeLoading(1000)
    .cacheInMemory(true)
    .cacheOnDisc(true)
    .considerExifParams(false)
    .imageScaleType(ImageScaleType.IN_SAMPLE_POWER_OF_2)
    .bitmapConfig(Bitmap.Config.RGB_565)
    .imageScaleType(ImageScaleType.EXACTLY)
    .displayer(new SimpleBitmapDisplayer())


    .handler(new Handler())
    .build();  

ImageLoader.getInstance().displayImage(image_url_string,
            image_coupon, options);

请帮我解决这个错误。谢谢。

在这里，我建议您在创建新实例之前删除旧实例，因为每次创建新实例时，旧实例都不会释放以前的内存，所以当您的设备内存在一些尝试后变低时。它会导致内存不足错误。所以只需清除以前的实例和内存。

您需要在创建新实例之前删除旧实例。

我第一次在UIL中看到OOM。请您解释一下，您是在谈论ImageLoader的实例吗？如果是，那么我如何删除旧实例？在ImageLoader类中创建一个方法，然后在getInstance（）方法中将返回的对象allready分配给null。调用GC方法和垃圾收集器方法，并在需要时调用它
