I get a OutOfMemoryError at BitmapFactory.decodeByteArray when bitmap size is large; Following is the code snippet:
BitmapFactory.Options options = new BitmapFactory.Options(); options.inSampleSize = 8; Bitmap bitmap = null; bitmap = BitmapFactory.decodeByteArray(data, 0, data.length, options);..........
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

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 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

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:

In 2.2, it's now failing sometimes and my catch block no longer catches anything. Why would that be? Is there a better way to avoid a java.lang.OutOfMemoryError?
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 get an OutOfMemoryError in my app after changing the orientation. I have read, that if have to use Context.getApplicationContext() instead of a normal activity context??

I am currently trying to create an Android application that loops Audio from the mic to the earpiece, I can do that perfectly but when I do it over and over again in my application I eventually get an Out Of Memory Error.
Here is the code I use to create the Audio Loop:
CODE:.................
And here is the error I get:
CODE:........................
So the Error specifically focuses on this line in the code
CODE:.................
And it happens after I try to do the Loop several times, so say I start the application and after 10 times starting the loop I get the error.
So I think the buffer is simply becomiing full or something?? Is that correct? If so how would I keep clearing out the buffer?
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?
I am developing a simple app which does a little bit of image-processing. It's divided in two activities; the main one with some display elements and the second one which is used to capture images off the phone's camera.
To discribe my problem: I start the app, capture an image (by starting a new Intent with the subactivity) and all data is displayed correctly. If I capture another image after this, I run in an java.lang.OutOfMemoryError - bitmap size exceeds VM budget
I dont store the captured bitmap, in the second activity I just extract some data from it and pass it to the main-activity; finishing (finish()) the sub-activity afterwards.
when i download large data from website, i got this error information:
I/global (20094): Default buffer size used in BufferedInputStream constructor.
It would be better to be explicit if an 8k buffer is required.

In my app, I am creating a bitmap from its colors code like this :
CODE:...............
And often I get the outofmemoryerror: So how can I use the BitmapFactory optimisation to avoid this problem? because I don't have an input stream or a file, I only have an array containing my pixels.
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.
basically what i'm attempting to do is place several images into 1 zip file, and then read the images back out of the zip file, and draw them onto a canvas using BitmapFactory. This is what my code looks like, but when i debug i only get a source not found error.
Code: try {..............
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);
}
Is the BitmapFactory.decodeStream method thread safe?

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:...

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...........
In my application I am converting base64 string to image.For that I initially converted base 64 file to byte array and later am trying to convert to images.
To convert to Images I am using the below code

FileOutputStream fileOutputStream = null;

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 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 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?
View 9 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.
I'm downsampling an image via BitmapFactory.decode then base64 encoding the bytes to ship to the server. (long story on the latter part of that formula) It seems this process nukes all Exif data in the image data. Am I approaching this the wrong way or is this a fact of life?
