out-of-memory

问题 I made a custom file manager, and it is working fine. but it is loading and scrolling very slowly and suddenly there was outofmemory error. I am adding images on the side of the text view package com.example.fileexplorer; import java.io.ByteArrayOutputStream; import java.io.File; import java.util.ArrayList; import android.app.Activity; import android.content.Context; import android.graphics.Bitmap; import android.graphics.BitmapFactory; import android.graphics.Color; import android.graphics

问题 I have an Activity with a grid layout where display images from SD folders. When I select a folder, all images are added to a String list (clean when folder is changed), and images construction is in getView() method, using these strings from the list. It works properly for 5 or 6 times (images from folder are displayed), but then I change the folder and I get an 'outofmemoryerror' in the getView() from the custom BaseAdapter (see code line), but I don't understand my leak problem... Images

问题 While loading .gapp files from disc using PersistenceManager.loadObjectFromFile I got the, "Exception in thread "main" java.lang.OutOfMemoryError: Java heap space" Error. I increased the heap size to a maximum of 2048M and got the issue fixed. Is there a better alternative way to solve this issue when loading a large set of .gapp files. 回答1: I think not, if you are using the default garbage collector. It needs the max heap size parameter for its work. Note that the memory is really needed.

问题 Actually this is what i am trying to do Ad=<100820x20164 double> and b= <100820x1 double> also Ad is sparse matrix and b is non-sparse .Below is the original Problem and i try to change the statement A=V'*V + y_0*y_0'; using the block processing technique as you told me , now the problem is on the assignment statement mentioned below. V=Ad; b_1=b; x_0=ones(size(V ,1) ,1); y_0=V'*x_0; A=V'*V + y_0*y_0'; b=V'*b_1 + dot(x_0,b_1)*y_0; %%%%%%%%% Modified using block processing below %%%%%% V=Ad; b

问题 I have been using normal matrices from numpy to store a Matrix for a physics project. The size of the matrix is determined by the physical system. So for instance if the system has parameters: L=4 and N =2, then the matrix is of dimension 4C2 = 6, so the matrix is a 6x6 matrix. This is fine except for now I need larger size i.e 20C10 = 184,756. So the matrix required is now a 184756x184756 matrix, which when I try to create an empty matrix of this size gives me a memory error. (with 16GB of

问题 Here's my problem: I have a JasperReport ( mainReport ) with one subreport ( subReport ) which, at the same time, have one subreport ( subSubReport ). My problem comes when I try to execute it from my web app. Those reports are extracted from an Oracle database, thus I'm passing an InputStream as "path" for them. Since I've been testing "paths" as InputStream (obtained from the same database) I know it works when I have a simple mainReport -> subReport hierachy... that's why I'm pretty sure

问题 I've got the following code which is designed to read a directory and compress it into a tar.gz archive. When I deploy the code onto the server and test it with a batch of files, it works on the first few test batches, but after the 4th or 5th batch, it starts consistently giving me java.lang.OutOfMemoryError: Direct buffer memory even though the file batch size stays the same and the heap space looks fine. Here's the code : public static void compressDirectory(String
