I am facing a problem of Out Of Memory Error that is bitmap size exceeds vm budget while changing the orientation of the Droid mobile (but not in any of other mobiles like Android normal and Android small).I am displaying 10 images in grid view, each one size is less than 20kb. If i insert 6 images then it doesn't arise that error.

View 1 Replies View RelatedPosted my problem here too HERE: A beginner..Im doing a school map app.
First of all I have background with 4 buttons ( level3, level4, level5, level6) I try and click all the buttons, normally after clicking 3 of it, the next one will crash.(each level button goes into a level map, whereby clicking the room image buttons, I will enter into the gallery-imageswitcher)
I have at least 5 imageswitchers in each level maps,so that about over 20 imageswitcher galleries overall.
I did all my stuffs using DRAWABLES instead of BITMAPS.. I have tons and tons of images (because its a school map, show all the photos in my school, and all those backgrounds and imagebuttons)
I did some research, and those who have problems are those using bitmap. Some of the ways that can be solved is system.gc();, and bitmap.recycle...(not so sure how to use it though)
In my main background - starttour.java Code...
PS: I have tons of images in the app; I have at least 5 imageswitcher gallerys in each level, so that kinda adds up to over 20 imageswitchers in my app.
I've problem with memory of the bitmaps, I'm creating a lot of bitmaps and then releasing them by recycle() and after many retries I get:
java.lang.OutOfMemoryError: bitmap size exceeds VM budget
How to get rid of this? The problem is that even if i close the activity (call onDestroy()), in next program run the bitmap memory is still allocated! (I've also android:clearTaskOnLaunch="true" in my manifest). This is horrible. Can anybody help me with that? I suspect that every application using BitmapFactory.decodeResource must get this exception in some call! Do you have any idea what's going on?
It immediately has trouble with memory. In the LogCat this error is displayed, java.lang.OutOfMemoryError: bitmap size exceeds VM budget. I'm using recycle () and System.gc () but I get the same error. My application, is pressing a button switches to the next image and the images are 854x480 Loading images from the SD Card. show the images as follows
Bitmap imageB; ImageView imgV;
imageB = BitmapFactory.decodeFile ("sdcard / img.png"); imgV.setImageBitmap (imageB);
Release is as follow.
@ Override protected void onDestroy () { super.onPause (); imageBG = null; System.gc ();
}
I am doing the following in my app, which at times results in the above error.
Action 1: Button on Main activity calls all pictures using ACTION_PICK (results in a thumbnail view of all pictures on my phone). User picked image (URI) is then passed over to next activity where the image is displayed (ImageView) full screen. When I hit back, I go back to the main activity. If I try to open all pictures and pick a picture again, I get a FORCE CLOSE and the logCat data says "OutofMemoryError: bitmap size exceeds VM budget.
Action 2: I get the same error and FORCE CLOSE when I try to rotate the full-sized picture by changing phone orientation back and forth.
What am I supposed to do to save memory? I can't change the use case of my app... the user has to follow the above steps. How can I free up memory without having to change anything in my app.
In my application i have a functionality where a user can take photo and poet it to a web server or select a photo from galerry and upload.
So initially i used to get below exception for the very* first time* i used to select a photo:
Android: OutofMemoryError: bitmap size exceeds VM budget. then i used:
*options.inSampleSize = 2;*
Now the problem is im still getting the same exception *the only difference is im getting exception after 2-3 times.*
i.e im able to upload 2-3 (one by one) photos and then i get the exception. any suggestions?
While I'm trying to resize a photo (originally on a sd card), grabbed using :
InputStream openInputStream = contentResolver.openInputStream (photoUri);
I got the following stack trace when calling : Bitmap bitmap = BitmapFactory.decodeStream(openInputStream);

Do you know an alternative way to resize a picture ? without calling BitmapFactory ? and without getting such an exception ? Thanks in advance for your help Anthony
I'm using ListView to display images which I provide through an ImageAdapter class. it works great on my device (and on many other devices which I tested it on), but somehow when I'm using the emulator and I'm long-pressing the up/down button - I'm getting an outOfMemory error after 10-15 seconds.
I tried clearing cache, canceling cache, etc. - nothing helped.
I know this crash is pretty rare (i couldn't reproduced it on any "real" device), but I can see on DDMS that "GC freed" are getting bigger during that long press and I can't find a way to clear them.
I've been reading about performance issues decoding Bitmaps and have received the OutOfMemoryError "Bitmap exceeds VM budget" issue when I would expect to not be out of memory and read online that this is a common problem referred to as a bug in the framework by many devs. Typically, I get the error mentioned above on my second pass. Let's say I load a somewhat sizable Bitmap successfully and then recycle it and even set the ref to null. When I call this same method a second time that does the work of loading my Bitmap(s) into memory...
I've read on previous posts here and elsewhere online that there are a few things that can be done with BitmapFactory.Options (for instance, providing an input buffer explicitly). But, before proceeding blindly in using what I've found, I'm hoping someone with more knowledge of these classes can shed a little more light...........
I'm writing game with a large amount of .png pictures. All worked fine. Than I added new activity with WebView and got memory shortage. After that I made some experiment - replace game .png images with ones that just fully filled with some color. As result memory shortage had gone.
But I suppose that Bitmap internally hold each pixel separately so such changes should have no effect. Maybe this because of initial images have alpha channel and my test images have not it?
But actually question is: Will decreasing .png images files sizes make some effect on decreasing usage of VM application heap or not?
I have a very large image and I only want to display a section the size of the display (no scaling), and the section should just be the center of the image. Because the image is very large I cannot read the entire image into memory and then crop it. This is what I have so far but it will give OutOfMemory for large images. Also I don't think inSampleSize applies because I want to crop the image, not lower the resolution.
Uri data = getIntent().getData();
Input Stream is = getContentResolver().openInputStream(data);
Bitmap bitmap = BitmapFactory.decodeStream(is, null, null);
Any help would be great?
So I'm loading images from a web service, but the size of the images are sometimes smaller or bigger than other images and the visualization looks silly when I put them in a ListView in android. I'd like to fix the size of my ImageView so that it only shows a portion of the image if it's larger than a preset amount. I've tried everything I can think of setting the setMaxWidth/setMaxHeight, setting the scale type to centerCrop, using ClipableDrawable wrapping my BitmapDrawable, setting using Drawable.setBounds(). I've tried setting in the XML and programmatically, but neither worked. I'm very surprised setting max width/height didn't do anything. Below is the XML I'm using ImageView definition in my layout file
View 1 Replies View RelatedHad my Legend for about a month and a half now and I've started getting 'low phone memory' errors. Looked in the memory lists and it says the only 'biggies' are maps at 4mb each (and there's 4 of them?) and 'HTC mail' at 116mb. I only have my hotmail account, texts, and Gmail and they're all empty. Not really got that many applications installed (4 or 5) and had to remove some just to get the phone to stop reminding me. I've emptied the drafts, trash and cache and it made little to no difference.

View 1 Replies View RelatedI have the following code which I tried to build a Bitmap from an input stream and I want my output bitmap to be 20 x 20:
BitmapFactory.Options opts = new BitmapFactory.Options(); opts.outHeight = 20; opts.outWidth = 20;
InputStream stream = // an input stream to my image Bitmap bm = BitmapFactory.decodeStream(stream, null, opts);
But when I tried it, I do get a bitmap from the inputstream, but it does not scale it to 20x20 which I specified in the BitmapFactory.Options.
How can I determine/calculate the byte size of a bitmap (after decoding with BitmapFactory)? I need to know how much memory space it occupies, because I'm doing memory caching/management in my app. (file size is not enough, since these are jpg/png files).

View 2 Replies View RelatedIs there any way to pre allocate the memory required for a bitmap. Android's memory model is making it very difficult for me to cache images I need to cache.
It would seem the problem is because the VM heap rarely shrinks itself, so I would like to just allocate memory for bitmaps ahead of time? but I can not figure out how to do this?
Ok I am at the end of my rope. I am doing some image processing. I have a large image file which I open and create a smaller bitmap from. At the end of processing I call recycle on everything. I null everything. I run GC manually.
I then try edit another image and I get an out of VM memory error. Bitmap exceeds etc etc.
I am looking at the heap and the secone edit doesn't seem to cause it to increase at all.
What else can I do. Surely google cannot possibly be suggesting that we can open one large bitmap per session and thats it?
Part of my application allows the user to color-correct images. When i open an image for editing, i'd like to know what, more or less, the available bitmap memory is for the device that the app is running on.
For the G1, the limit is use is about 6MByte (about a full-size image that can be taken by the phone (3MPixels) with 16 bit color ==> 6MByte). If i try to open anything larger, i often get an out-of- memory exception. Limiting it to 6MByte reduces these OOM exceptions by a great deal. However, i can see future devices having more memory available because (as one of the reasons) they can take larger pics (e.g. 5MPixel or something).
Right now, my app just uses a hard-coded limit of 6*1024*1024. Is there a way to make this variable, to future-proof this by examine the device my app is running on. If so, how?
I have an ImageView that contains a bitmap. Now the bitmap can change size within a known range. This makes the surrounding views to relocate which I want to prevent. I've tried setting margins and padding for the ImageView but without success.
View 1 Replies View RelatedI have a list view that display about 25 images with size 60x60 pixels. I dowload this images from internet and I store in an arraylist as Bitmap. I need to save it in a arraylist because a listview will recycle views and so I need, wenn the user scroll, to display the image in the new view WITHOUT downloading again from internet
But after some time I got
java.lang.OutOfMemoryError: bitmap size exceeds VM budget
It seams that I got this exception about after loading 20 images ...
Reading in forum I have read about memory heap.
I try to check the memory heap usage with: Debug.getNativeHeapAllocatedSize and Debug.getNativeHeapSize()
When the exception occours both are about 4M.
But android has more than 4M?
When the application start the values are a little less to 4M so it seams is not a big memory usage or memory leak.
To be sure I want to call : ActivityManager.getMemoryClass() but this method is and instance method and I can't find the object to invoke!
But this method say, that al min should an application have 16M!
Any help? I have seen many topics in google ... but all speak about recycle. But if I recycle a bitmat ... then should I download again from internet?
Should I store the image on flash memory or sd card instead an arraylist in memory?
My game - Tower Raiders - is continually floating fairly close to running out of bitmap memory. Unfortunately, I haven't found good information on profiling bitmap memory usage so that I can optimize / make informed decisions / add new content if it allows / etc.
I'm aware that bitmap memory is not heap memory, as it's allocated natively. But that it is accounted for somehow in the VM and influences garbage collection. Maybe it's an oversimplification of how bitmap memory works - but I'd like to find a tool etc or some way of determining I as the game is running right now, there are no more than X bytes of usable bitmap memory remaining.
So, if anyone has any advice etc that would help me in these respects I would greatly like to hear about a workflow for this.
I've read a lot of previous messages on this topic but couldn't find universal agreement on the whole. I can't reproduce this in house, but a customer got an OutOfMemoryError when using an icon chooser dialog.
This dialog is much like the Grid1 example - only it's in a dialog.
The bitmap memory seems to run out after running the dialog a few times for a customer, resulting in java.lang.OutOfMemoryError: bitmap size exceeds VM budget. Should I try to call recycle on the bitmap from an ImageView when I reuse the view? Or would the ImageView do that anyway?
But even if I do that, that's only a small portion of the bitmaps because most of them are seen without scrolling. The Adapter and the GridView are both local variables and therefore shouldn't be referenced after the dialog is dismissed.
I do believe that it should be possible to use many bitmaps in an app - Google Maps does it, Picture Gallery does it. But maybe I need to learn more rules. Some say you should call bitmap.recycle, some say you shouldn't have to. Many say calling gc.collect will make it worse, etc.
I have a large bitmap that i would like to keep in memory when the qwerty keyboard is visible. My app is always in landscape, so this is the only configuration change that will cause a reDraw.

View 5 Replies View RelatedI'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.
