如何处理内存不足的错误？ [英] How to handle out of memory error?

问题描述

我使用下面的code显示位图在我的ImageView。 当我尝试加载的大小，例如大于1.5MB的形象它给我的错误。 任何一个建议我的解决方案？

 尝试{

                         URL aURL =新的URL（myRemoteImages [VAL]）;
                         URLConnection的康恩= aURL.openConnection（）;

                         conn.connect（）;
                         InputStream的是= NULL;
                         尝试
                         {
                             是= conn.getInputStream（）;
                         }赶上（IOException异常E）
                         {


                             返回0;

                         }
                         诠释一个= conn.getConnectTimeout（）;
                         的BufferedInputStream双=新的BufferedInputStream（是）;

                         位图BM;
                         尝试
                         {
                             BM = BitmapFactory.de codeStream（之二）;
                         }赶上（例外前）
                         {
                             bis.close（）;
                             is.close（）;
                             返回0;
                         }
                         bis.close（）;
                         is.close（）;
                         img.setImageBitmap（BM）;

                    }赶上（IOException异常E）{
                        返回0;
                    }

                    返回1;

解决方案

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

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

I am using following code to display bitmap in my ImageView. When I try to load image of size for example bigger than 1.5MB it give me error. Any one suggest me solution?

  try {  

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

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


                             return 0;

                         }
                         int a=  conn.getConnectTimeout();
                         BufferedInputStream bis = new BufferedInputStream(is);  

                         Bitmap bm;
                         try
                         {
                             bm = BitmapFactory.decodeStream(bis);
                         }catch(Exception ex)
                         {
                             bis.close(); 
                             is.close();  
                             return 0; 
                         }
                         bis.close();  
                         is.close();  
                         img.setImageBitmap(bm);

                    } catch (IOException e) {  
                        return 0;
                    }  

                    return 1;

Log cat:

解决方案

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

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