Android :: Allocate Memory To My Application?
Jan 25, 2010
I am getting a "bitmap size exceeds VM budget" error. I have read that there is a 16MB memory limit. In this thread Romain Guy says that "you can only allocate 16 MB of memory for your entire application".
However, my app must be running out of memory long before it reaches that limit. So my question is: how do I allocate memory to my application ... how can I get the allocation to my app increased (within the 16MB maximum)?

I have an app that displays a camera picture as part of it, but if the picture is in memory I get an out of memory exception when an allocation of any size happens no matter what. If the app uses a seekbar in addition to my PictureView the ~900 bytes it allocates are too much. I even tried to load a 16x16 monochrome image on top of the camera pic, but the 256 bytes were too much. I find it extremely unlikely that the object containing the image is precisely the size so that using it alone never causes a crash, but allocating even 256 more bytes exceeds the memory budget. Does anybody know what the problem is?

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?

I captured an image by android G1, now trying to display it as ImageView but it gives me memory allocation exception.
CODE:.............
The default image resolution of G1 camera is 2048 * 1536
I also tried to compress image on selection but still same exception.

Some of you may met the same problem, I was using BitmapFactory.decodeStream, and got this exception: Code...
I know the reason is because the BitmapFactory is trying to decode an uncompressed version of a big image(in my situation, jpg). I can use BitmapFactory.Options.inSampleSize to fix it. but my question is what's the maximum size that VM would like to allocate for loading a image with BitmapFactory? so I can do some scale before it loads.

My application uses a single activity to switch between different views. I premise I'm loading a good amount of bitmaps in one of this view (say the gamescreen view) constructor but I recycle everything on the onDetachedFromWindow method.All the Bitmaps are static and most of them loaded with BitmapFactory. decodeResource method.Furthermore I'm using a gallery wich content is a simple layout with eight imagebuttons.I know all the complications using this widget and all the risks of using static bitmaps, but, I guess my problem does not entail them because my application is running well if I try to switch between these two view (and I've tried to do it about 30 times without crashes!!!) but when I pause and resume the application two times (pause->resume->pause->resume) I run out of memory, and often without the crash message (it just stays on the actual view).

My question may look naive but I do not know how to formulate it more correctly. The problem is that I create and use large simple type arrays in my application.
And I get errors like: ERROR/dalvikvm-heap(1763): Out of memory on a 7907344-byte allocation.
Yes, it's big enough but task management tools claim that my application is using only 30MB of memory, while other at the same time use 50MB and even 110MB (have seen once) and there is still 190MB of free memory in the system (not system applications, just other ordinary applications I have installed). If all applications are provided with the same heap size at startup how can they grow so big?

I am experiencing a memory / resource leak on a T-Mobile G1 device with my application. I installed the "Task Manager" application from Android market and my memory usage is not monotonically increasing. It stays relatively flat over time. Furthermore, none of the other processes are chewing up tons of memory either (really, I can get into this state with just my app running). I am not experiencing this problem on any of the other Android phones (including Eris, Hero, and Droid).
The interesting thing is that if I kill my application, the phone is *still* very slow and sluggish. The only thing that seems to be able to get me out of this situation is a battery pull. If I run my application for about 3 hours, the phone starts to become very sluggish. Even simple operations like hitting the "home" button take many seconds. I'm not sure what to do at this point and am wondering where I can go from here.

I am trying to get the memory usage for every application at different periods of time. I have checked the docs / threads / forums, and i only found that you can get the total available memory value, but i could not find in the sdk an api call for getting the memory used by a single application. I know that one way to do this is by reading the values from /proc/ <pid> virtual file system but this is painful for the device cpu. Can you help me figure out how to solve this problem ? Or does anyone know how settings -> applications -> manager applications read the memory usage values.

how I can find the memory used on my Android application, programmatically. I hope there is a way to do it. Plus I would like to understand how to get the free memory of the phone too.

Is android's memory 16MB limit per Process or Application? If the limit is by process, I can make some services remote. That means the service will be in different processes, and the limit will be 16 x N.

I have a problem with my application, and it's about a Virtual memory error: ERROR/AndroidRuntime(19790): java.lang.OutOfMemoryError: bitmap size exceeds VM budget
The story is like this: I have an activity (let's call it A), the user click on a button from this activity, then i will make an api call somewhere in the internet, and after the result is back i start a subactivity (let's call it B).
In the activity B i have to dinamicaly load some images from the resources folder. I load the images into bitmaps -> drawables -> imageviews. After the user click's on some buttons i have to setResult(..), finish(), and get back to activity A.
The thing is that, goes from activity A to B, then B -> A, then A -> B for a few times, my app crashes with the message above: it doesn't have enough memory to load the interface.
I can not maintain the activity B on the stack because i don't want the user to go to this activity without going through activity A first.

How do I find out how much memory my openGL application is using at any given moment, including sounds, textures, and everything else? I've been wrestling with DDMS for hours and all it seems to show me is basic object allocation counts. I must be missing something, but I haven't had any luck searching. LONG VERSION: I've got an otherwise operational beta Android game which crashes out after a while on my device (Droid X). I'm fairly sure my problem is that my textures are not being properly cleared from memory. I'd like to confirm this fact before I start blindly making changes. My game does fairly frequent level transitions. During these transitions I typically dump a texture file, wait a bit, then load a new one.
Over time the application performance degrades. After 10 or so transitions frame rate starts to take a nose dive. 10 or so more and it usually dies. Prior to dying I see log messages like this: 08-23 12:26:58.038: DEBUG/Cursor(1265): fillWindow is not executed because Cursor object is closed. 08-23 12:27:27.186: INFO/ActivityManager(1239): Low Memory: No more background processes. And then eventually: 08-23 12:27:46.952: INFO/ActivityManager(1239): Process com.thup.lunchbox (pid 4927) has died. There are no specific error messages of any sort. I've got lots of ideas for things to try to fix this (e,g, glDeleteTextures), but I really want a way to measure before I start trying to fix.

Ive had an HTC G1 and I now have the Samsung Behold II. Theres a problem I've noticed on both phones. Lets say I have 60mb of flash memory and I download an app that is 5mb. That would put me down to 55 if my 2nd grade math serves me correctly. Now if I were to uninstall this app, my phone will only go back up to 58mb. Even after restarting the phone 10 times, taking the battery out or doing whatever, it remains at 58mb of memory.
I want to know why does this happen? And is there any way to recover that lost storage? I just find it a bit crappy management of memory. Because this problem can be more drastic, I downloaded a 20mb app which sucked balls, to which I quickly uninstalled. I only got 12mb of the 20 back. Thats 8mb lost somewhere. Again, I'm looking for at the very least an explanation

When I install my application with Eclipse ADT (by simply run and choose device that appears in the list) through USB onto device, sometimes I noticed it consumes internal memory (storage) space even though application is already loaded on the device (exactly same version - just some minor code changes)As my application size getting big, this is really annoying because eventually it will use up all initial storage space of ~70MB and I have to factory reset in order for me to continue testing my application on real device.I did little investigation and find out this seems to happen when
1) load/run application onto device for first time with USB
2) disconnect USB
3) restart Eclipse
4) connect device and try to load/run application onto device
5) internal memory goes down by application size ...
and it does NOT seem to happen as long as I keep USB connection and Eclipse still recognize the device. I'm just guessing here, but maybe does Eclipse ADT creates temporary file of some kind that's get left behind when I disconnect USB? I'm running RC30 so I don't have root access and can't check system files/folders but is there any way to look for these temp files (if any) and clear out either from Eclipse, or using adb shell command?So for now, I leave my device connected to Eclipse all the time but I want to use it as phone as well as sometimes I want to show to my friends to get some feedback etc it would be really nice if I can somehow load application onto device, disconnect and keep testing/using phone.Has anyone experience this issue? If so, is there any walk around to this problem? Or could you point me out what I'm doing wrong here? I tried few things myself, such as close Eclipse right after I launch my application on device, disconnect USB etc but nothing seem to work.

I am making an app for Android, in my Activity I need to load an array of about 10000 strings. Loading it from database was slow, so I decided to put it directly into one .java file (as a private field). I have about 20 of these classes containing string arrays and my question is, are all the classes loaded into memory after my application is started? If so the Activity in which I need these strings would be loaded quickly, but the application as a whole would have a slow start...
Is there other way, how to very quickly load an 10000 string array from a file?
UPDATE:
Why I need these strings? My Android app allows you to find "journeys" in Prague's public transit - you choose departure stop, arrival stop and it finds your journey (have a look here). My app has a suggestions feature - you enter leter "c" as your departure stop and a suggestions ListView appears with stops starting with "c". For these suggestions I need the strings. Fetching the suggestions from database is slow (about 400ms on G1).

I was curious how to read the available memory in the process manager screen. I don't know what the x+x in x also x in x means. I don't want to install an app that eats up memory to see how much memory is being used. I'm not trying to control how it uses memory but, I do like to see how much memory there is available after I install and run new apps and/or widgets so I can try and only use lighter apps when possible.

I have made a game with just one activity.. I just replace the views when I want to change screen. The game runs fine for a really long time inspite of what ever I do within the game.
But once I close the main game, by calling finish on the only activity in the application, and then when I start again, within the next 30 secs it crashes telling VM budget exceeded..
When I don't have a dispose() or a delete method in JAVA.. how the, am I supposed to remove the objects used in memory.. moreover I have android:launchMode="singleInstance" in my manifest

Can you pls let me know how much is the free memory for application, it says it has 1.5 GB internal memory but I wanna know exactly how much is the free memory left for application installation
Settings -> SD Card and phone storage -> scroll down and see Internal phone storage...how much you see there pls
the original desire has only 140 MB for app installation which was pathetic
