Sorry if this sound newb but.. =[

Im working with an application which need to load a large amount of images onto a textview, i didnt use webview becuz sometimes it doesnt lead to mobile view so i decide to parse the content and use html.fromHtml to show it to the Textview.

Problem is: if i load a page is luckily there not much images, it run pretty smooth. otherwise it get the error like below...

anyone know if theres a way that i can dispose the source from the system memory after it finished reading the image?...or...any other way will fix my problem?

i used the source from here Android ImageGetter images overlapping text

查看这篇文章，它使用从 SD 卡/图库中获取图片的示例来了解如何对图像进行下采样，从而避免此问题。这是一个很容易解决的问题。
