out-of-memory

I develop one android app for book read. The Book pages and audios are download from Amazon Bucket. After downloading it stores on SD Card. I place to two button for next and previous pages. When I display pages It gives me Out of Memory Exception. 11-03 10:59:39.199: E/AndroidRuntime(13566): FATAL EXCEPTION: main 11-03 10:59:39.199: E/AndroidRuntime(13566): java.lang.OutOfMemoryError 11-03 10:59:39.199: E/AndroidRuntime(13566): at android.graphics.BitmapFactory.nativeDecodeStream(Native Method) 11-03 10:59:39.199: E/AndroidRuntime(13566): at android.graphics.BitmapFactory.decodeStream

I have 13255 images, each 240 x 240 pixels wide, the biggest 15,412 bytes in size and the smallest 839 bytes. I am trying to loop through the folder adding each of them to a File[]. Once I have an array of each image I am then placing them inside a BufferedImage[] ready to be looped through and drawn onto a larger single image made up of each individual one. Each image is named in the form of Image x-y.png However, I keep ending up with a java.lang.OutOfMemoryError: Java heap space error. I have no idea why. I have tried altering the size of the memory available to the JVM by adding parameters

I am using Tomcat for deploying a web application withe following PermGen configurations: JAVA_OPTS="-Djava.awt.headless=true -Dfile.encoding=UTF-8 -server -Xms1536m -Xmx1536m -XX:NewSize=256m -XX:MaxNewSize=256m -XX:PermSize=256m -XX:MaxPermSize=256m -XX:+DisableExplicitGC" Please I want to know the following: Is the whole memory used by Tomcat should be 256MB or Tomcat consumes other memory for other reasons ? How can I monitor the memory used by Tomcat to avoid reaching PemGen max size ? Also please be noticed that I have 3 Tomcats with the same previous PermGen configurations, running on

This is a theoretical question . Can a flood of system out on java applet , cause applet to go out of memory ? If yes what would be an easy solution to remove multiple sysout spanning across multiple files ? A single System.out.println(x) can cause an out of memory error, if x.toString() uses too much memory. Can a flood of system out on java applet , cause applet to go out of memory ? It is size of the resulting String which matters, not the number. More messages will be slower, but make no difference to the amount of free memory after a Full GC and that is what counts. 来源： https:/

I wrote a python script which I am using to download a large number of video files (50-400 MB each) from an HTTP server. It has worked well so far on long lists of downloads, but for some reason it rarely has a memory error. The machine has about 1 GB of RAM free, but I don't think it's ever maxed out on RAM while running this script. I've monitored the memory usage in the task manager and perfmon and it always behaves the same from what I've seen: slowly increases during the download, then returns to normal level after it finishes the download (There's no small leaks that creep up or anything

I'm developing web application in jsp/servlet,i had an issue with netbeans and Java. My program needs large data process. So I used -Xmx512m to increase the maximum heap size via Tools -> Servers -> on the Platform tab there is a VM option below Java Platform. Then it works fine.. Now my issue is i'm building the WAR file, directly deployed and run in my another machine Tomcat for demo, here i'm facing the same issue java out of memory error-heap space i also tried with environment variable set CATALINA_OPTS=-Xms512m -Xmx512m this also didn't help me how to resolve this issue?, Please point me
