Android :: BitmapFactory.Options - Exceeds VM Budget
Nov 5, 2010
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'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);
04-26 14:57:57.213: ERROR/dalvikvm-heap(349): 6291456-byte external allocation too large for this process. 04-26 14:57:57.224: ERROR/(349): VM won't let us allocate 6291456 bytes 04-26 14:57:57.234: DEBUG/skia(349): xxxxxxxxxxxxxxxxxxxx allocPixelRef failed 04-26 14:58:58.005: WARN/dalvikvm(349): threadid=15: thread exiting with uncaught exception (group=0x4000fe68) 04-26 14:58:58.014: ERROR/AndroidRuntime(349): Uncaught handler: thread Thread-19 exiting due to uncaught exception 04-26 14:58:58.153: ERROR/AndroidRuntime(349): java.lang.OutOfMemoryError: bitmap size exceeds VM budget 04-26 14:58:58.153: ERROR/AndroidRuntime(349):at android.graphics.BitmapFactory.nativeDecodeStream(Native Method) 04-26 14:58:58.153: ERROR/AndroidRuntime(349):at android.graphics.BitmapFactory.decodeStream(BitmapFactory.java:304) 04-26 14:58:58.153: ERROR/AndroidRuntime(349):at android.graphics.BitmapFactory.decodeFile(BitmapFactory.java:149) 04-26 14:58:58.153: ERROR/AndroidRuntime(349):at android.graphics.BitmapFactory.decodeFile(BitmapFactory.java:174)
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

Posted 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'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 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.

I am tring to get a image from the images stored on the sdcard of my Android but i am getting a skia error using BitmapFactory When I just take the image directly without using BitmapFactory class I get the image. But the purpose of using BitmapFactory is scaling down the image size by using inSample =4;
but I get skia as the error..................

I'm having issues with BitmapFactory.decodeStream(inputStream). When using it without options, it will return an image. But when I use it with options as in .decodeStream(inputStream, null, options) it never returns Bitmaps. What I'm trying to do is to downsample a Bitmap before I actually load it to save memory.
I've read some good guides, but none using .decodeStream.........................

I have an activity which performs an image search, the results (URLs of thumbnails on the web) are rendered in a GridView. My GridView adapter class delegates creating the actual Bitmaps to an AsyncTask that loops to sequentially fetch the image content from each URL using HTTPClient, and creates the Bitmaps using:
BitmapFactory.decodeStream(entity.getContent()).
I found that the above method sometimes returns "null" silently instead of creating a Bitmap. The occurrences appear to correlate with larger stream sizes (I check this by logging entity.getContentLength()). However, if I put a breakpoint just prior to the decodeStream call & then resume immediately every time I hit it (i.e. pause briefly on each iteration), the Bitmaps are created perfectly every time. All the images are quite small (most <10K), so the download & decodeStream happens fairly quickly. There are never more than 10 images processed in one AsyncTask.

I can't wait to try out the new 1.6 goodies, but first I'm retargeting my existing applications, and I decided to start with Daisy Garden. Changing to android:targetSdkVersion="4" caused the application to segfault on startup and discovered that the BitmapFactory.decodeResource method now performs scaling based on screen density. In this case the behaviour is unwanted - I'm loading a set of masks that are scaled later during composition. So I've quickly inserted the following method, which seems to perfectly mimic the previous behaviour:
private Bitmap loadBitmap(int resId) { BitmapFactory.Options options = new BitmapFactory.Options(); options.inTargetDensity = 1; options.inDensity = 1; return BitmapFactory.decodeResource(context.getResources(), resId, options);
}

I am working on an app that displays photos which are downloaded from Flickr. I obtain a Bitmap object from a byte array, which in turn is read from the relevant Flickr URL, as follows: Bitmap bitmap = BitmapFactory.decodeByteArray(data, 0, data.length); The problem is that the resulting bitmap is pixelated and I can't figure out why. To demonstrate, here is an example of a picture created via BitmapFactory.decodeByteArray versus the original picture obtained directly from the relevant Flickr URL:...

Our Android app does a lot of image decoding. We fetch a lot of images from the internet, local storage caches, etc. Up to now, these images are being decoded on the UI thread (using BitmapFactory.decodeX() methods). It's been causing some timeout crashes because the UI doesn't respond quickly enough to user input.
I could write a little AsyncTask that encapsulates decoding, but I'm not sure that's a good idea. Spawning threads is expensive, and that would be spawning and tearing down a ton of them. So what's the best way to put this on another thread? Do I need to go to the extent of writing a Service? That seems a little heavy-weight. Are there any solutions for this already out there?

For my current application I collect images from different "event providers" in Spain.
However, when downloading images from salir.com I get the following logcat output: 13970 Gallery_Activity
I Fetching image 2/8 URL: http://media.salir.com/_images_/verticales/a/0/1/0/2540-los_inmortale... 13970 ServiceHttpRequest
I Image [url] fetched in [146ms] 13970 skia D --- decoder->decode returned false
Searching for that error message didn't provide much useful results.

why when I load images from files using BitmapFactory.decodeFile and passing in a BitmapFactory.Options with inPurgeable set to true, I still get OutOfMemoryError? For example, doing the following many times, with lots of different resources works fine:
BitmapFactory.Options opts = new Options() opts.inPurgeable = true; bitmap = BitmapFactory.decodeResource(resources, resId, opts);
However, doing the following causes an OutOfMemoryError
BitmapFactory.Options opts = new Options() opts.inPurgeable = true; bitmap = BitmapFactory.decodeFile(myFile, opts);
In reality my code isn't as simple as outlined above. What I'm really trying to do is load a couple of bitmap resources draw them on a bitmap backed canvas, and then write this new bitmap to file, just so it can then be finally re-read into memory with the inPurgeable option set to true (using BitmapFactory.decodeFile).

I'm using the Camera.PreviewCallback.onPreviewFrame to try to generate a bitmap from the byte array passed to that method. If I use BitmapFactory.decodByteArray it returns null. I'm assuming that the array is correctly formatted since the data just comes right from the camera, so what could the problem be?

I 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.
