Mike, Something in your original post (which I hadn't previously read) might be a clue. You said that this often happens after orientation changes. Orientation changes must be accelerating whatever memory leak you have because they cause your activity to be shutdown and restarted. Make sure in your onPause code you're doing any necessary cleanup and double check anything you might be doing with static members.

[android-developers] Re: Allocation too large for this process
Justin, with the BitmapFactory.Options way, I'm getting this problem even when not changing orientation a single time. It's known that the Gallery leaks, I demonstrated that to Romain in a different post, so I know that my bitmaps will never be deleted (presumably), but Romain suggested using BitmapFactory.Options to reduce the amount of leaked memory (and to reduce the app's memory hunger in general, regardless of any leaks). However, the downsizing of the bitmap didn't help at all.

Use a smaller image. A 700KB JPEG is fairly massive. Bear in mind that JPEG files have to be decompressed when they get turned into a bitmap. Apparently the uncompressed form of your image exceeds a limit on how big an individual memory allocation can be. Furthermore, a 700KB JPEG has *got* to have a resolution bigger than what the G1 can handle. If you intend to show the whole image via some sort of panning mechanism, consider splitting the image up into discrete tiles, akin to what Google Maps does. -- Mark Murphy (a Commons Guy) http://commonsware.com Android Training on the Ranch! -- Mar 16-20, 2009 http://www.bignerdranch.com/schedule.shtml --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Allocation too large for this process
Any ideas? I've created a little test app that's nothing more than a Gallery with an adapter that creates an ImageView and populates it through new BitmapDrawable(BitmapFactory.decodeFile(filename)), with always the same filename. Every time a new view is created, the data object size increases by 2KB or so. What is classified as a data object and how can I track them? Likewise, the 1-byte array heap also goes up by 32KB every time, as do the 4-byte arrays (by 4KB). And finally, how is the 16MB heap an application has split up? In the constructor of my test app, Runtime.getRuntime().freeMemory() returns ~760KB. -Mike On Nov 16, 12:34 pm, EboMike [EMAIL PROTECTED] wrote: I'm reading JPGs off the storage device, and they are typically 1024x768 since they came straight from a server.

Yeah, I could have the server crunch the image to 480x320 first, but I'd like to reserve the option to add a zoom function later. Besides, it DOES work most of the time, and if I really have a 16MB heap, there shouldn't be any issues whatsoever. By the way, it does seem like there might be a leak - in the data object row in the Heap DDMS view, I seem to be leaking 10KB or so with every image. How can I track down what's going on there?

16 MB is the maximum limit of the heap. Your app can use at most 16 MB. The heap in your application will grow as more memory is needed.

[android-developers] Re: Allocation too large for this process
I'm reading JPGs off the storage device, and they are typically 1024x768 since they came straight from a server. The VM typically errors out allocating ~1MB of memory. (One time, it errored allocating 30KB even though the gc freed up 900KB just prior to that). Yeah, I could have the server crunch the image to 480x320 first, but I'd like to reserve the option to add a zoom function later. Besides, it DOES work most of the time, and if I really have a 16MB heap, there shouldn't be any issues whatsoever. By the way, it does seem like there might be a leak - in the data object row in the Heap DDMS view, I seem to be leaking 10KB or so with every image. How can I track down what's going on there? Like I mentioned earlier, my BitmapDrawables are deleted properly according to the allocation tracker. -Mike On Nov 16, 12:02 pm, Romain Guy [EMAIL PROTECTED] wrote: What is the size of the Bitmap you are trying to create?

[android-developers] Re: Allocation too large for this process
Thank you for your clarification, Romain! That is very helpful. I was initially using a fixed final Drawable array for my switching background images, and did not find any reason for memory leaks while I did not have to wait long for hitting the heap limit, but I am aware that it is easy to overlook such things. Even though my PNG background images together take only about 35 KB on disk, the decompressed versions will of course eat a lot more. Yet after moving over to using a final Bitmap array for the same image set I had far less memory related problems, and to further minimize memory usage I later changed to loading images one by one by doing a BitmapFactory.decodeResource (getResources(),) dynamically, only for the active background image. DDMS currently indicates zero leakage for my app, but I do not know how this was for my older breaking versions, because (at that time being unfamiliar with DDMS) I initially had trouble getting the heap info display to update. I hope Mike can do some allocation tracking like you indicate, and playing with some alternative implementations may help narrow down the possible causes of his problems, which may be entirely different from mine (and the one in the other thread). Thanks On Nov 15, 10:01 am, Romain Guy [EMAIL PROTECTED] wrote: Applications have a hard limit of 16 MB. As for the other bug you mention, it has nothing to do with memory usage; the implementation of BitmapFactory that reads images from URL will fail over slow connections. Besides, when you load a Drawable from the resources, it simply calls the BitmapFactory to decode the resource anyway. If you hit an out of memory exception, your app *is* using too much memory (which you might very well be leaking, it's not that hard, especially if you use static fields in your code.) You can use DDMS and its allocation tracker, as well as its various GC/heap monitors to see when and how your application is allocating so much memory. I have run myself into this issue several times over the past 18 months and every time, the application was leaking something (especially on screen rotation.) --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Allocation too large for this process
I forgot to mention that on the emulator I never had memory trouble even with my older versions: my app would run for over 1,300 iterations without ever crashing whereas the G1 would crash with some OutOfMemoryError within 10 to 20 iterations. However, the camera part is of course very different for emulator and G1, so I cannot exclude the possibility that in my case the main problems originated there since it is now known that G1 camera programming must be done with white gloves. I did and do not have a G1 to look at possible memory leaks on the physical device. On Nov 15, 10:30 am, blindfold [EMAIL PROTECTED] wrote: Thank you for your clarification, Romain!

[android-developers] Re: Allocation too large for this process
Hi Romain, I don't know what you're doing with the Camera but a picture coming from the Camera uses several MB of memory so... In part for this reason I normally use the camera preview mode, which on the T-Mobile G1 takes only 3 * 480 * 320 / 2 ~= 230 KB per image, so no memory problem there, and even when expanding this into an integer pixel array for further image processing it would still be a manageable 480 * 320 * 4 ~= 614 KB. However, for my purposes I need only 64 x 64 pixel views, such that sub-sampling during YUV411 decoding and prior to further image processing keeps the extra memory use (on top of G1's hard-coded 230 KB preview data) far below this 614 KB (namely just 64 * 64 * 4 ~= 16 KB). The uncompressed still images from takePicture() are indeed several MB by default because of G1's 2048 * 1536 pixel snapshots, or about 6 MB when mapping to an RGB_565 bitmap. In fact it is one of the still unanswered questions which still image resolutions are supported by the G1. There is of course the heap-devouring 2048 * 1536, and experimentally it was determined that 480 * 320 also works (I tested that yesterday together with another developer who has a G1), but we have no comprehensive and authoritative list of supported resolutions to make proper trade-offs with memory use, while Android (SDK 1.0 r1) has no API for querying the camera about supported resolutions. The latter makes that Android-based camera applications cannot be made future-proof for when other Android phones with other cameras hit the market. I find this a serious concern as I have expressed on multiple occasions. Thank you for your further explanation about the internals of Drawable. I cannot be sure if my getting rid of using Drawable was indeed the reason that all my heap problems vanished, but your explanation further encourages me not to touch it with a stick unless I fully understand what I am doing - or what Android is doing. :-) Peter On Nov 15, 8:10 pm, Romain Guy [EMAIL PROTECTED] wrote: I don't know what you're doing with the Camera but a picture coming from the Camera uses several MB of memory so... One issue with Drawable is that they have a Callback pointer to a View. That means if you keep your Drawable in a static field (directly or indirectly), you forever keep a reference to a View. And that View has a reference to the Context (your Activity), which has references to all the widgets and resources on the current screen. That makes it very easy to blow up the heap :) --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Allocation too large for this process
Hey blind, you're right, I'm using Drawables -- BitmapDrawables, to be precise. This is for an ImageSwitcher, so I need a Drawable of some sort (since I'm loading jpeg images off the storage device, so I can't use resources). I've tried BitmapFactory.decodeFile() instead of BitmapDrawables constructor that takes a String, but I get the same result, except that the OutOfMemoryException is now in BitmapFactory.decodeFile() itself instead of a cryptic callstack like before.

[android-developers] Re: Allocation too large for this process
Easier said than done. An end-user of my app immediately got an OutOfMemoryError on a real G1 (not the emulator) when capturing just s single image from the camera at 2048 x 1536, the only specified resolution that I could find on the web for the T-Mobile G1. Do you know of any lower still image resolutions supported by the G1, Romain? Thanks!
