Android : Fix For OutofMemoryError / Bitmap Size Exceeds VM Budget
Jun 16, 2010
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?

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'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 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?

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.

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 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'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...........

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

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.

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).

I am using bitmap image that i have to rotate on fling. its actually a circular image that will act like a spin wheel. so image resolution is like 1000 x 1000 but when i rotate this image and redraw it android give me an exception " java.lang.OutOfMemoryError: bitmap size exceeds VM budget "

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 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.

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?

I am 1) taking a picture and 2) then draw another Bitmap on top of it 3) then I store it
I am doing it as follows and it works on the emulator.
On the device I get a OutOfMemoryError: bitmap size exceeds VM budget android.graphics.Bitmap.nativeCopy(Native Method) android.graphics.Bitmap.copy(Bitmap.java:199) in the line copy the Bitmap to get a mutable Bitmap.
CODE:...........
What I am asking:
a) Is there a better way to do what I am doing? 1) take a picture 2) draw another Bitmap on top of it 3) then I store it
b) What is the best way to create a mutable Bitmap from the picture I just took with the camera?
In my app, resolution is not an issue. If it works better for small photos that would be fine.

I'm having problems with ListViews in my application. I thought everything was fine until I noticed that if I scrolled up and down through the list quickly a number of times, sooner or later the app would crash with an OutOfMemoryError.
When I searched for the error I noticed a number of posts related to loading images. As my list items included a small arrow png, I assumed the problem lay here. However even after removing this and all other drawables I had (gradient background and list separator) the problem still remains.
Here's the stack trace
CODE:...............
I've had a look in DDMS and noticed that the percentage memory used in the heap doesn't go above 70%. Also, doesn't the reported 66K seem like a very small amount to be causing a crash?

I have two questions actually:
Is it better to draw an image on a bitmap or create a bitmap as resource and then draw it over a bitmap? Performance wise... which one is better?
If I want to draw something transparent over a bitmap, how would I go about doing it?
If I want to overlay one transparent bitmap over another, how would I do it?

I have the same problem as described here, but I will supply a few more details. While trying to upload a video in Android, I'm reading it into memory, and if the video is large I get an OutOfMemoryError. Here's my code:
// get bytestream to upload
videoByteArray = getBytesFromFile(cR, fileUriString);
public static byte[] getBytesFromFile(ContentResolver cR, String fileUriString) throws IOException {
Uri tempuri = Uri.parse(fileUriString);
InputStream is = cR.openInputStream(tempuri);
byte[] b3 = readBytes(is);
is.close();
return b3;
}
public static byte[] readBytes(InputStream inputStream) throws IOException {
ByteArrayOutputStream byteBuffer = new ByteArrayOutputStream();
// this is storage overwritten on each iteration with bytes
int bufferSize = 1024;...........................

I get an OutOfMemoryError every time i change the screen orientation and I am having a hard time finding the mistake...
The Activitie's view consists of an ImageView, two Buttons and a Spinner. I don't have static variables and can't imagine where i could leak a context.
Most of the times, the exception is thrown at setContentView (R.layout.upload); sometimes it goes fine until imgUpload.setImageURI(imageURI);
The images i am displaying are form the G1's camera, so about 500kb and 2048x1536pixels
Here is some code:
