Android : Out Of MemoryError With Bitmap / Working With Large Images With No Memory

Jul 22, 2010

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.

Android : Out Of MemoryError with Bitmap / working with large images with no memory


Android : Out Of MemoryError - Bitmap Size Exceeds VM Budget

Dec 18, 2009

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.

Android : Java.lang.Out Of MemoryError / Bitmap Size Exceeds VM Budget

Apr 26, 2009

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

Android : Crop Bitmap Without Reading Entire Bitmap / Cannot Read Image Into Memory

Jul 21, 2010

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?

Android : How Might One Create A Large Bitmap In Droid

Aug 10, 2010

I am trying to build an Android application which can take several photos taken by the camera, and merge them into one giant image. For example, I might take three photos and arrange them in a vertical stack for output as a single image. Ideally, I'd like to be able to keep the images at the original size. Unfortunately, using Bitmap.createBitmap() causes an OutOfMemoryException before even approaching the size of one photo of camera dimensions. Is this possible? Or do I just need to resort to scaling the photos before trying to merge them into a single Bitmap?

Android :: Work With Large Bitmap - Rotating And Inserting To Gallery

Feb 19, 2010

I need to take a picture with the camera and, if depending on the picture size, rotate it before saving it into the gallery. I'm using

Intent imageCaptureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
imageCaptureIntent.putExtra(MediaStore.EXTRA_OUTPUT, uri);
startActivityForResult(imageCaptureIntent, IMAGE_CAPTURE);

To take the pic and save it to a temporary file. Then

Bitmap bmp = BitmapFactory.decodeFile(imagePath);
String str = android.provider.MediaStore.Images.Media.insertImage(cr, bmp, name, description);
To save it. This is the code i have tried to use to rotate the bitmap.............

Android :: Decode Large Resolution Images?

May 5, 2009

I want to decode high resolution pics something like 8 mega pixel images and view it. when I try to decode them I get out of memory exception. Decoding of single 8 mega pixel also fails . From the Imagamanager code and other post I could use BitmapFactory.Options inJustDecodeBounds I could get a scaled down version of the Image . code...

Is there any way to decode part of the Image and fill it on the screen and by scrolling decode other region of the image and display it.

Android :: Store.Images.Media.get Bitmap Returns Error

Aug 31, 2010

ContentResolver cr = getContentResolver(); Uri pic = Uri.parse("content://media/external/images/media/3");
Bitmap bm = Media.getBitmap(cr,pic); The above code is written in onCreate method of my Activity class. It throws the following error:
08-30 12:27:22.352: WARN/System.err(245): java.io.FileNotFoundException: No content provider: [content://media/external/images/media/3]
What could be wrong? The file in question is there because I launched Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.INTERNAL_CONTENT_URI) in another method and got back the Uri of the picked image from the returned intent.

Android :: Resize Large Bitmap File To Scaled Output File

Jul 26, 2010

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.

Android : Anyway To Pre Allocate Memory For A Bitmap?

Sep 27, 2010

Is 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?

Android :: Out Of Memory Error On Large Bitmaps And Activity Life Cycle

Jul 24, 2010

I 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..............

Android :: Store A Large Dictionary With Low Memory Footprint - Fast Lookups?

Feb 16, 2010

I'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.

Android : Looking At Heap Bitmap Memory Per Session?

Feb 26, 2009

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?

Android : How To Guestimate Available Bitmap Memory On A Device

May 13, 2009

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?

Android :: Out Of Memory On Bitmap But There Is Free Heap Space

Aug 10, 2010

I 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?

Android : Profiling Bitmap Memory Usage To Optimize?

Jan 15, 2010

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.

Android : Bitmap Memory Handling With ImageView.setimage

Jun 4, 2010

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.

Android : Is Decreasing Size Of .png Files Have Some Effect To Resulted Bitmap In Memory

Apr 8, 2010

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?

General :: Google Play Music - Hogs Large Chunks Of Memory Storage?

Nov 26, 2013

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.

Android :: Scrolling Large Image - Working Good But Slow

Nov 12, 2009

For a project, I'm displaying an image with sizes 800 x 600 and I've implemented my custom scrolling (horizontal and vertical) - which is works fine. However, my problem is that it's not fast enough. If you continuously move your finger on screen for instance, scrolling is not responding fast enough. There is a lag and you need to wait (say 400-500ms) for new scrolled image to be loaded. Now below I described how I implemented scrolling and my question is that
- How can I make it faster, if possible - Is there any other better way to implement this.

My custom scrolling solution:
* I have a Main activity, SurfaceView and a thread
* In main activity, I'm using GestureDetector and override onScroll method.
* In onScroll method of activity, I'm passing values to SurfaceView's "handleScrolling" method.
* In "handleScrolling" method, I'm calculating proper values and using "newImage = Bitmap.createBitmap(myImage, starX, stopY, SCREEN_WIDTH, SCREEN_HEIGHT)"; to create a new, "scrolled" image.
* Then in thread loop, I'm drawing this "newImage" to canvas.

Android :: Out Of Memory Calling MediaStore.Images.Media.get Bit ­map

Apr 15, 2010

After I've used a MediaStore.ACTION_IMAGE_CAPTURE intent to take a photo, when I try to retrieve the captured image, I sometimes get an out of memory error as shown below. The odd thing is the huge size of the memory trying to be allocated is always reported as 10,077,696 (x99c600). However, the image file is much smaller, typically around 750,000 bytes.Any suggestions on how to get around this problem? I'm testing this on a Nexus One with firmware version: 2.1-update1 and Build number: ERE27. Code...
