java.lang.OutOfMemoryError：位图大小超过虚拟机预算是多少？ [英] java.lang.OutOfMemoryError: bitmap size exceeds VM budget?

问题描述

朋友，

我用下面的code，显示位图在屏幕上，有下一个和previous按钮来更改图像。

i am using following code to display bitmap on screen and having next and previous buttons to change images.

和获得内存不足的错误

新的code

HttpGet httpRequest = null; 


                             try { 
                                     httpRequest = new HttpGet(mImage_URL[val]); 
                             } catch (Exception e) { 
                                 return 0;
                             } 


                             HttpClient httpclient = new DefaultHttpClient(); 
                             HttpResponse response = (HttpResponse) httpclient.execute(httpRequest); 

                             Bitmap bm;
                             HttpEntity entity = response.getEntity(); 
                             BufferedHttpEntity bufHttpEntity = new BufferedHttpEntity(entity); 
                             InputStream is = bufHttpEntity.getContent(); 
                             try
                             {
                                 bm = BitmapFactory.decodeStream(is);
                                                                              }catch(Exception ex)
                             {
                             }
                             is.close(); 

旧code

URL aURL = new URL(mImage_URL[val]);  
                             URLConnection conn = aURL.openConnection(); 

                             conn.connect();  

InputStream is = null;
                             try
                             {
                                 is= conn.getInputStream();  
                             }catch(IOException e)
                             {
                             }
BufferedInputStream bis = new BufferedInputStream(is);  
 bm = BitmapFactory.decodeStream(bis);
 bis.close();  
 is.close(); 
 img.setImageBitmap(bm);

和它给我的错误去codeR->德code返回false。

and it was giving me error decoder->decode return false.

在大小大于400KB的图像。

on images of size bigger than 400kb.

所以谷歌搜索后，我有了新的code的答案 老code没有给我出内存不足的错误对这些图像，但德codeR->德code返回false，所以我选用新的code。

so after googling i got new code as answer the old code was not giving me out of memory error on those images but decoder->decode return false, so i choosed new code.

任何一个指导我该如何解决，哪些是为了显示实时图像的最佳方法？

any one guide me what is the solution and which is the best approach to display live images?

推荐答案

您应该取消code与inSampleSize选项，以减少内存消耗。 <一href="http://stackoverflow.com/questions/477572/android-strange-out-of-memory-issue/823966#823966">http://stackoverflow.com/questions/477572/android-strange-out-of-memory-issue/823966#823966

You should decode with inSampleSize option to reduce memory consumption. http://stackoverflow.com/questions/477572/android-strange-out-of-memory-issue/823966#823966

另一种选择inJustDe codeBounds可以帮助你找到正确的inSampleSize值的http://groups.google.com/group/android-developers/browse_thread/thread/bd858a63563a6d4a

Another option inJustDecodeBounds can help you to find correct inSampleSize value http://groups.google.com/group/android-developers/browse_thread/thread/bd858a63563a6d4a
