I am downloading a audio file from server on sd card. It is showing me OutOfMemoryException. This is my code.. --------------------------- package com.android;

I have a large bitmap (say 3888x2592) in a file. Now, I want to resize that bitmap to 800x533 and save it to another file.I normally would scale the bitmap by calling Bitmap.createBitmap method but it needs a source bitmap as the first argument, which I can't provide because loading the original image into a Bitmap object would of course exceed the memory (see here, for example).Is there a way to read a large image file with 10MP or more and save it to a new image file, resized to a specific new width and height, without getting an OutOfMemory exception?I also tried BitmapFactory.decodeFile(file, options) and setting the Options.outHeight and Options.outWidth values manually to 800 and 533, but it doesn't work that way.
View 4 Replies View RelatedI have a problem with a strange out of memory exception that only occurs on some devices (mostly HTC Desire). It happens there every time a user starts a certain activity (no matter how - there are two paths to that activity) and i'm really puzzled as to why (i checked for leaks and couldn't find any)...
The error is either thrown when calling setContentView or shortly after.
This is the code block that throws the error:
CODE:.........
As i said - the error is usually thrown when calling setContentView or when calling getMonthTimeStamps()
getMonthTimeStamps is a helper function which creates a list of dates available in the internal database. It creates a couple of (small objects) and returns an ArrayList.
Here is the function:

I'm not claiming that my code is flawless or perfect, but i really don't understand why this error is thrown. The XML-layout doesn't contain any references to images and not very complicated (textview, spinner, tablelayout).

Just got myself a new 16gb memory card, and want to put in my rooted Hero with Elelinux 1.6, but having trouble.Heres what I've done so far:
* I copy/pasted everything from my old membery card onto my pc desktop.
* Put new mem card into my hero - sorted out the partitions (in case I go back to 2.1 and need app2sd)
* Formatted the sd card within Android
* copy/pasted everything from my pc desktop onto my new memory card
The problem is, none of my installed apps/widgets are there. I tried to install Titanium from the marketplace, but for some reason wasn't able to - it just sort of hung on the download screen, (even though I didn't actually choose to download it?)
I'm developing an image editor for Android. When I do some operations with small pictures (600x600 - 1024x768), the program work well. But when I do some operations with big pictures, I always obtain an OutOfMemory Error. I read read many post trying to have the image in memory. Also I looked at the Android's Gallery, trying to simulate the effect of loading the image with lower quality and get the complete quality after a while. But I doesn't get to work with large images.
I thought of using the parameter inSampleSize but I raised the problem of having to perform operations on the image and save it with the original size, so it no longer serves me. The only thing I've done is use the parameter inJustDecodeBounds and display an error to the user if the image exceeds the available memory.
Is there any possibility of working with large images with no memory problems? I need urgent help.
I've got this problem: When my program using too much memory, it die. Is there an exception or something else to warn me? How can I catch it?

I call camera.release and camera.stoppreview in surfacedestroyed function, but that doesnt help.
What is the right way to release all resources? Could somebody please show his working surfacechanged, surfacecreated and surfacedestroyed functions? I have empty onPreviewFrame function, should i put something there?

View 6 Replies View RelatedI have a scrollable map app which for now has a huge bitmap. It loads fine on startup, but when it looses foreground status and the user brings it backs again im getting an out of memory error. In onPause it trashes the bitmap using recycle, and marks it as null. The onResume checks to see if map==null and will load the bitmap back again, which is crashing the program despite me recycling the bitmap...Here are some bits of code. All of the other references to Bitmap map first check if it is null before loading/drawing..............
View 1 Replies View RelatedI'm developing an android word game app that needs a large (~250,000 word dictionary) available.
I need:reasonably fast look ups e.g. constant time preferable, need to do maybe 200 lookups a second on occasion to solve a word puzzle and maybe 20 lookups within 0.2 second more often to check words the user just spelled.
Lookups are typically asking "Is in the dictionary?". I'd like to support up to two wildcards in the word as well, but this is easy enough by just generating all possible letters the wildcards could have been and checking the generated words (i.e. 26 * 26 lookups for a word with two wildcards). as it's a mobile app, using as little memory as possible and requiring only a small initial download for the dictionary data is top priority.
My first naive attempts used Java's HashMap class, which caused an out of memory exception. I've looked into using the SQL lite databases available on android, but this seems like overkill.
I read that people moved Avatar from the microSD card to the internal memory so they can put in their 8GB microSD. How was this done?

so the problem is: if the image size is too big - it'll got an exception (out of memory exception)
what i want is, to handle even if the handset got the lower spec hardware, it doesn't go to that exception (but it'll take a longer time to process the image) is it possible to do that?

I have a ton of videos that were transferred from my old phone to my Eris, and they must have been saved to the phone's built in memory. I want to transfer them to the card so I can put them into my computer. Does anyone know how to do this? I have been unable to sync using the cord because of a driver issue.

View 3 Replies View RelatedI am trying to implement the functionality to resume a large file download, but have not found how to start downloading from a position that is not at the beginning of an InputStream.I am currently using the InputStream.skip() method to go to the position where I want to resume the download, but have found that this method actually reads all the data over the network and then throws it away.I would appreciate some help in learning the correct way to start reading from the resume offset of the internet file being downloaded, so that I can avoid wasting the phone network bandwidth, and also avoid the extra time delay caused by re-downloading all the data that was already previously downloaded.

View 1 Replies View RelatedMy application needs to intensively manipulate (read-write) on some structured text data.The size of the data is significant 1Mb. And there is initial data available for the user to start with.My idea is to put this data as a file in the .apk. Then, on initial application launch to read this data and populate Android SQLite database with it. Then just work with this database. But after the database is populated the data file is no longer needed. And I'd like to remove it to free some memory. Alternate approach is to work with this data file instead of SQLite database. But I assume SQLite would work a magnitude faster then i/o on my data file..

Yesterday i streamed a few tracks whilst testing an FM transmitter for my nexus 5.everything worked perfectly but today i went out and about and as another test i turned off WiFi and mobile data and then went into play music and all those tracks i streamed yesterday played !!!! .
i checked the tracks and none of them were down as being stored for offline access on my nexus 5.
i checked my music folder .....nothing there
then i checked my apps and found that play music was taking up nearly a Gigabyte in data storage.i cleared all the app data and cache went back into play music and had to reestablish my google account and found that now none of the tracks were playable until i switched wifi back on.
this shouldnt be happening... unless i select the download link in a track to keep it on my phone the music should just stream.
I've been trying to diagnose a memory leak in an Android application I'm writing. I got a heap dump loaded into Eclipse, but the results I'm seeing are very curious. There are some 20,000 instances of an exception (specifically, LDAPException from the UnboundID LDAP library) in the heap with no inbound references.
That is, they show up at the root of the dominator tree. The OQL SELECT objects e FROM com.unboundid.ldap.sdk.LDAPException e WHERE (inbounds(e).length = 0) returns over 20,000 results, totalling to nearly all of the heap. And yet, the GC runs before the heap dump and I can see that it's running in the console, repeatedly, during the execution of the leaky code. If these instances have no inbound refs, what could be keeping them alive?
I also tried doing a "shortest paths to GC" query. It shows one LDAPConnectionReader row retaining 2 instances, and ~20k LDAPException @ <addr> unknown rows with various hex addresses.
Update: I haven't had time to further diagnose this since posting it, and the bounty I posted is ending before I likely will. I'm awarding it as best I can now, lest the points go to waste. Thanks to everyone who looked into this! I will come back later and update again with the results of further diagnosis, when life is a little less hectic.
I have just bought a new 32 GB SD card. Made a folder on my PC and copied the content of the original SD card to folder. New folder on PC says contents 950 mb. Original SD card in Desire is 2.6 GB used space. What have I missed. Is there a better way to transfer content of Old SD card to new. What is RAW format? (Format of old SD card in phone.)

View 4 Replies View RelatedI had yesterday received the Samsung Galaxy I7500 from Optus, and have today been playing around with it.
Right now, I am attempting to transfer files to the phone from the PC via the USB cable, so that I can have custom ringtone & notification sounds.
I have mounted the device using the phone so I can access the internal memory via Windows Explorer, and have made the 2 folders (notifications + ringtones), however when I transfer the file, it STARTS to transfer then the device disconnects and I get the following error message:
Error Msg.jpg
I have noticed that the first 5 or 10 seconds of the music transfer successfully before it gets cutoff...
I have tried to use NPS to try transfer the file (using the Media Manager), which appears to transfer the file fine, but those songs I transfer across does not even appear in the "Music" Application that the phone came with.
I have also tried to transfer (via Windows Explorer) other file types eg a PDF file but they also cause the device to disconnect...
I am using Windows 7 Professional 64 bit edition - I do not know if this is causing some sort of problem with the device?
I have a class that extends View. I override the onDraw method and allow the user to draw on the screen. I am at the point where I want to save this view as an image. I Can use buildDrawingCache and getDrawingCache to create a bitmap that I can write to the SD card. However, the image is not good quality at a large size, it has jagged edges. Since I have a View and I use Paths I can transform all by drawing to a bigger size. I just don't know how to make the Canvas bigger so when I call getDrawingCache it doesn't crop all the paths I am just transformed. What is happening is I transform all my paths but when I write the Bitmap to file I am only getting the "viewport" of the actual screen size. I want something much bigger.
