从Internet加载图像时,位图大小超过了VM预算?

我正试图在ImageView中显示来自Internet的图像。

这就产生了以下错误,任何人都会引导我在这里犯什么错误

公共位图displayLiveImage(字符串imagesrc) { 位图BM; 尝试{

                             URL aURL = new URL(ImageSrc);  
                             URLConnection conn = aURL.openConnection(); 

                             conn.connect();  
                             InputStream is = null;
                             try
                             {
                                 is= conn.getInputStream();  
                             }catch(IOException e)
                             {
                                 return null;
                             }

                             BufferedInputStream bis = new BufferedInputStream(is);  

                             bm = BitmapFactory.decodeStream(bis);  
                             bis.close();  
                             is.close();  

                        } catch (IOException e) {  
                            return null;
                        }  

                        return  bm;

    }
