Android :: OutOfMemory With 9M Free Heap Because Of Bitmaps!
Mar 3, 2010
Our app has some memory peaks, which let the heap grow to 13M. After the peak, there's 9M of free heap. Everything's fine until Bitmap objects come into play. Despite having 9M of free heap creating Bitmaps, which have only some 100k, now fail with a OutOfMemoryException!
My theory: Allocation fails if (Java) heap *size* plus external allocations (e.g. Bitmaps) exceed 16M, no matter that there is lots of free memory in the heap. The VM could shrink the heap, but actually does not. Would be quite a flaw in the VM.
Does anyone share this theory?
On the downside of this theory: I do not see anything appropriate (killing the process is probably not) an app developer could do to prevent those OutOfMemoryExceptions given that those memory peaks are legitimate and unavoidable.

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?

I am facing an Out Of Memory Exception while playing with the application for sometime. I looked in to HeapDump using MAT, and also monitored the heap through DDMS. But HeapDump looks good to me and DDMS heap size is well in limit. Still I am getting this Exception.

I really don't know why it's giving me this error... I load an ImageView with an image of 692kb .jpg, using scroll options, so you can scroll it around... the strange it's that when the mobile it's connected to the VM it's less possible to happen. So...how can I prevent this? is there anyway that I can free memory when starting the app? can I tell the system to free memory before loading the image?

I'm having a hard time resolving a crash report. It's an OutOfMemory exception that occurs during the setContentView in the onCreate of my main activity.
I just want to be sure I understood Android LifeCycle well :
1) The onCreate of my main activity is called once and only once during the life time of my application ? Is that correct ?
2) Just like for the big bang, before the oncreate of my activity, nothing exists for that activity, so memory consumption is zero, no objects exists right ?
So what can cause that sometimes, with random framework and devices, I get an OOM exception ? I mean if say my background image is causing this, it should blow up everytime, on every device, shouldn't it ? I mean the result should be reliable.
The background image is a standard jpg : 360*480 weighing 37kb, nothing fancy really :s
The crash report below :

I create Android applications for my job. Eclipse is open all day and I am frequently editing XML files for layouts, etc. I find that creating/editing these XML files pushes up the memory use of Eclipse. Eclipse never seems to release any of the memory and eventually Eclipse tells me that there has been some sort of workbench out of memory error and I have to exit. It will not let me save or do much of anything after this point.
Is there a workaround for this? I don't want to have to exit Eclipse and start it up because of this memory issue. Why won't Eclipse free up its memory use? It just keeps going up. I am still having issues with running out of memory, the eclipse.ini suggestions did not fix it.

memory - after only 2-3 minutes I get Force Close and outOfMemory Error. I have only onCreate (I know, stupid, but I didn't knew for anything else as I started only few weeks ago) and inside I have...
@Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main);
many lines of code...manipulating with SQLite databases...

I have an Android app that in the onCreate() method, preloads a lot of graphics.
When I test my app on my HTC Aria and launch it, it runs fine. However, if I press the back button to exit my app, and then launch the app again, it crashes with an OutOfMemoryError: bitmap size exceeds VM budget. If I then launch the app for the third time (right after it has crashed) it launches fine. Then if I close and re-launch it, it crashes again with out of memory. It continues this every-other-time-crashing pattern forever if I keep trying.
I checked to see what life cycle methods were being called and onStop() and onDestroy() are both being called when I exit the app, yet I have a feeling that something is not yet being cleaned up and that by "crashing" the app when I try to launch it the second time, it somehow free's the memory.
Any thoughts on what could be happening or how to remedy this? Please let me know if you need me to post more info.
Info: My app is fairly simple and only has 1 activity that plays some frame animations.

I have a bitmap that I load from the SD card by allowing the user to choose a picture to display. Once the bitmap is created, I set the Bitmap in an ImageView:
CODE:.........................
This works fine. But, if I change the screen orientation from portrait to landscape, and back again a few times, I always get an OutOfMemory exception.
In onPause, I call mBitmap.recycle(), and then on onResume, I call the above code again to create the bitmap and set the ImageView. Since I'm recycling the image each time, how can I get an OutOfMemory error?
In any case, since that failed, I found a post that said to try using onRetainNonConfigurationInstance() and getLastNonConfigurationInstance(). See post http://stackoverflow.com/questions/3250987/save-cache-when-rotate-device/3252547#3252547. I changed my code to work this way, and I still get an error. Changing the code, I had the call to getLastNonConfigurationInstance() in onCreate(), and removed all code in onPause and onResume. provide some way to simply load an image, and then be able to pause and resume the Activity without running out of memory?

I have an application which fetches data from server and shows it in different lists in my application. I used the adb shell procrank command to find out the memory usage of my application It takes 10 mb for the UI (I have a single Activity ,but many layout files), And the data which comes from the server is stored in memory arrays for logical representation on UI (As well as database)and it takes 6 mb of the memory .So application's runtime size reaches to 16 mb and then many a times its crashing after that with OutOfMemoryException. Another major problem is that later for the next client release , the data comming from the server will be around 12 mb.. :( :( So i need to do a major restructuring in the App.I beleive that i cannot increase my App size from 16 mb to more So my question here is , can i have two seperate applications , one of which will fetch the data from the server and keep it in memory as well as database and another App will be used for showing the UI and it will do an inter Application communication to fetch the data and display it on the UI in this App. So the 1st App wil be a backgrond App which will handle Server communication as well as data storage , the second App will start this 1st App .

I am writing a clock widget that uses customised bitmaps (so the widget loads the bitmap from the sdcard) Just have a couple of questions regarding how updates work:
1. if i want to display seconds on the clock widget will the widget load the bitmaps off the disk every second or can they be cached somehow so it doesn't reload off the disk each time. or If it does reload a bitmap each second, would this use a lot of power?
2. If i load the customised number bitmaps into a static array and then pass them as bitmaps to the widget would this use less power than just loading off the SD card?

I have following example code:
Character c = CharacterFactory.getCharacter(CharacterEnum.SpecialCharacter); //factory has applicationContext reference to get bitmaps from R. ... Paint bitmapPaint = new Paint(); ... View::onDraw(Canvas canvas) ... canvas.drawBitmap(c.bitmap(), 0, 0, bitmapPaint);
For some reason (must be something simple) I do not see the bitmaps at the 0,0 of the canvas. Inspecting the bitmap and etc does not show anything obvious (nulls), I must have missed something. Is there something I should be paying particular attention to while drawing bitmaps?

I want to load bitmaps into ImageViews in Android, but I don't want to use the R.drawable syntax because I have a lot of images with a standard naming convention so it's much easier to get the image with some logic. For example, all my images are named:
img1.png
img2.png
img3.png
So if a user selects a value, let's say x, I show "img" + x + ".png" in the ImageView. Looks like Bitmap.decodeFile is what I need, but I need to know the syntax of how to get to my drawables folder since that's where the images are. Or if there's perhaps a better way.
I realize I could do this with a switch statement instead of concatenating the image name but that would be a lot of lines since I have so many images.

I am struggling to get Bitmaps blurred using Android.
I have seen a lot of information about using a simple kernel like
0 0 0 5 0 0 0
0 5 18 32 18 5 0
0 18 64 100 64 18 0
5 32 100 100 100 32 5
0 18 64 100 64 18 0
0 5 18 32 18 5 0
0 0 0 5 0 0 0
My problem is that I am really not sure how to multiply this with my Bitmap in an efficient way. Should I go through every pixel and image.getPixel(x, y)
while storing those values to a new array (so I don't have to get those values over and over again) and then go through the array and for each value add up the surrounding values multiplied by the corresponding field in the kernel divided by 1068 (in the case of the above kernel (= all entries summed up))?
Is there any better way to do this? Is there a simple solution for the borders?
Or is there even something available in the Android SDK I missed?

I've been trying to make a simple live wallpaper out of a boot animation. So basically i have about 50 .pngs in my drawable folder. I'm able to set the animation to about 10-20 frames and it works great. But once i set it to about 30 frames...I get an OutOfMemory Error. I was hoping maybe someone could take a look at my code and maybe give an example of how I could achieve more frames? That would help so much i've been looking at this for hours > <

I am trying to set a different wallpaper for every home screen, but I get OutOfMemory issues. I have 5 Bitmaps which I am trying to overlay on a wallpaper Bitmap which is 5 times the display width. Using the code below I get OOM. The problem seems to be the first line of code which creates the large wallpaper Bitmap. My question is whether there is a way to do this (i.e. some way that takes up less memory, or someway to allocate more memory?).

I am working on an application that downloads images from a url. The problem is that only some images are being correctly downloaded and others are not. First off, here is the problem code:
public Bitmap downloadImage(String url) {
HttpClient client = new DefaultHttpClient();
HttpResponse response = null;
try {.......................................
So what I have is a method that takes the url as a string argument and then downloads the image, converts the HttpResponse stream to a bitmap by means of the BitmapFactory.decodeStream method, and returns it. The problem is that when I am on a slow network connection (almost always 3G rather than Wi-Fi) some images are converted to null--not all of them, only some of them. Using a Wi-Fi connection works perfectly; all the images are downloaded and converted properly. Does anyone know why this is happening? Or better, how can I fix this? How would I even go about testing to determine the problem?

How can one track memory consumption in Android? The Android "Heap" view in Eclipse and java.lang.Runtime methods seem failing for my purpose. I tried to figure out how much memory my app consumes in order to make decisions for future directions. Most of the memory goes into Bitmap objects. Just to test memory consumption I created huge bitmaps in a Loop and logged the java.lang.Runtime memory values: created bitmap (610k free, 2371k total, 16384k max) created bitmap (615k free, 2371k total, 16384k max) created bitmap (615k free, 2371k total, 16384k max) created bitmap (615k free, 2371k total, 16384k max)
Nothing seems to hapen, but on the fifth Bitmap: java.lang.OutOfMemoryError: bitmap size exceeds VM budget at android.graphics.Bitmap.nativeCreate(Native Method) at android.graphics.Bitmap.createBitmap(Bitmap.java:343) at de.greenrobot.colorball.GameView.init(GameView.java:86)
This seems confusing at first. Is java.lang.Runtime the right place to check application memory stats in Android at all? Are Bitmaps allocated outside the app's heap? How can I track it?

I'm running into OutOfMemoryErrors when allocating bitmaps. This is not something I can reproduce with emulators, and has been reported by a few beta testers with the HTC Incredible. I'm not sure I can solve this directly, and my best hope is to follow best practices for bitmaps and memory thereof. But looking for those best practices based on groups archives left me with more questions than answers. If anyone has a chapter about this in their book, I will buy the book. Here are the things I've mulled over so far:
1. I have a bitmap for a drawing buffer. It is about 3-4 megabytes on some devices. This is the biggest bitmap I have, and without it, I wouldn't be able to much of anything useful in my app. I am assuming that it would not be useful to use inPurgeable if this is a bitmap that is drawn into. Is this true?
2. Next biggest in the hierarchy are some bitmaps that are about 22K bytes and 256K unpacked. Since I believe about 25 of these might be used at one time, I have a cache with a size of 25. I am careful to use BitmapFactory.Options.InPurgeable, so I believe that could make them take only 22K each, but I don't see that as guaranteed. Maybe they are taking 256K each, which would put me in the danger zone. As they are cycled out of the cache, I call bitmap.recycle(). I think this a good practice. Is it?
3. Next are some resources with icon size 32x32 pixels. There are about 50 that could be used or reused. If I use code like this:
Drawable s = mCtx.getResources().getDrawable(R.drawable.symbol_icon);
Where s is a local variable to rendering. Suppose I call this 37 times. Am I to assume that Android will do something smart like create only one bitmap for this resource even if it is used 37 times? Or am I to assume that Android will do something stupid like create 37 bitmaps and keep references in an obscure location that will prevent garbage collection? Do I need to get more access to these bitmaps and do something smart myself?
4. Finally are some other icons used for menus and ImageButtons. Most are declared in layout files - so I don't touch the bitmaps directly.
I'd like to make my memory usage more efficient, but don't want to spend time on things that will amount to shuffling chairs on the Titanic. And how do I best measure this usage? Interestingly enough, I've tried using the Allocation Tracker and it says I haven't allocated a single bitmap. In light of the above, I don't think that's right.

I have an application that receives information from a database, and is used to visualize 2D bitmaps onto a GLSurfaceView. The information received will determine the x-position of the bitmap, and which bitmap image to use (there are 4 different bitmaps in my res folder to choose from).
Below are the three classes that are being used. The Activity sets the Shapes objects that need to be drawn by passing an ArrayList to the GLLayer class. This ArrayList is passed to the instance of ShapeStorage class via another setList method. This class is responsible for drawing when they are received.
The problem that I'm having is the following. Suppose I receive one object (let's say that it's a square at it's located at x=1). Some time goes by, and I receive another shape (this time, it's a triangle, and it's located at x=-1). However, when this new shape appears on the screen, the old bitmap's appearance changes to a triangle, and the new one becomes a square. In other words, the objects themselves are at the correct position that they are supposed to be at, but the bitmap being associated with them has changed. Does anyone know what the possible cause of this can be? I'm still a newbie to OpenGL-ES, and while this code looks very convoluted, it just involves setting a bunch of various properties for the View. code...

I have two bitmap overlapped .The top bitmap is transparent and when user touch to screen i copy pixels from another bitmap to top bitmap.My goal is to give to users the feeling of erasing image with touching to see another image.However it is not working properly especially when user drags his finger too fast on the screen.I made a few tests and i beleive drawing bitmaps to the canvas every time cause the lag but i don't know how to fix it.

I definitely have a memory leak problem and i'm trying to figure out there. After 6-10 config changes i'm getting out of memory in regards to BitmapFactory. I'm kind of suspect that this is going on within adapter. I have a listview . ListItems are an thumbnail image ( ImageView ) and TextView for text.
Here is the getView code.
CODE:..................
And get ThumbnailBitmap() is basically BitmapFactory.decodeByteArray ..
Is it possible that i'm leaking drawables ? Heap is not increasing by the way .

I sometimes get bug reports that are caused by an OutOfMemory error. It happens when creating a bitmap, but I am pretty sure that it is not the bitmap size that is the real problem, because the instantiation of those images happens > 100.000 times a day without an error report. Those png images are of 4K size (on disk) anyway.
Those bug reports are very infrequent, but still I would love to get rid of them. I can't reproduce the memory growing over 10 MBs (actually way less) when using the app myself and monitoring the memory consumption in DDMS. I also, at no point in time, cache something or hold on to more than one item (article in my case) at a time, except in one list. There the list caches the visible components, which cannot amount to much too and is default functionality from the Android framework.

I have a list of 70 text items with image icons(which are stored in drawables folder).
If I launch application the first time and scroll the list slowly - the exception doesn't occur.
When the application is launched the first time and I scroll the list with 'fling' action the following exception occurs:

After that, if I kill the application with DDMS, start it again and scroll it with 'fling' action, exception doesn't occur. So the exception arises only if application is installed and launched the first time.

I have to manage several Bitmap in a ListView where each row is composed by one thumbnail and one textview. This ListView can be very long, over 500 rows...
There are two problems I have to solve:
1) it is better if I cache all the bitmaps, maybe using SoftReferences in a HashMap. I've tried this way, but I noticed a strange behavior with the SoftReferences. It seems that the GC clean them too fast. Why?
2) In order to implement the cache correctly I'd also like to understand which is the best practice you suggest me to realize a "image lazy loading". For example... I'm thinking to load all the data for first and then to load only the thumbnails, but only those really visible on the device screen at the and of the scroll action.
