Android :: Application Uninstalled Resulting Loss Of Memory
Feb 14, 2010
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 know about the ROM memory leak when you shut off the phone while BT is trying to connect, but I havent seen anyone talking about loss of RAM. you get it back after the phone is rebooted, but I noticed with taskpanel x and now with auto task killer. (I did a factory reset and attempted to use the phone w/o a task manager/killer and it was unbearable) I start the phone and had about 97 in the beginning with taskpanel x, everytime it would "kill all" the available memory would be lower, eventually in the 50's with everything killed and Id restart the phone and then Id be back in the 90's. now with auto task killer Im looking at 54.4 available when I wake the phone up, just restarted it and I have 76. does anyone else have this problem? I was hoping the 2.0 release would also come with a fix for this, but with noone talking about it, Im assuming its not being worked on, maybe its just my phone...

I've had unaccountable SD card memory loss since the update. Is it the upgrade or one of the apps I've downloaded since then. It seems to happen when I use picsaypro and an online animator even if I don't save anything.

I have noticed that I only have around 25 to 30mbs of available space on my internal phone memory. This ROM has a2sd how is this possible? Some of my application will not update now like handcent. Doesn't the phone run into problems when the memory gets that low?

I've down loaded quite a few apps that I have since uninstalled. I noticed that they are still listed on the My Downloads list with an option to reinstall. My question is, are these apps gone or are they still taking up some of the precious memory? If they are, is there a way to free upmore space by completely removing them?

I have a copy of settings.apk in my PC. How can i reinstall it again (Due to no USB debugging, I cannot connect to ADB as well).

There are certain apps that will not let your phone sleep as I noticed yesterday (TRAPSTER) and so I ended up uninstaling it because it kept my home screen up and it never went to black. I didn't want my battery to run down so I got rid of it but as I sit here thinking about it, couldn't I have gone into my Application settings and turned that app off until I wanted to use it again?

As you may all know Desire has nearly 150mb internal memory for applications so I'm doing my best to use it wisely,
My problem occured when I start to install and uninstall many applications just for testing. I've seen that every installed and uninstalled application leaves some files that fills up this 150mb.
At my phone I had, CoPilot live + Several games + Google Earth. Now I've none and but when I try to install CoPilot or Google Earth I'm facing the fact that there is no space left.
I think applications might be leaving installer file behind when applications installed through HTC Sync, this might be the only logical reason.

I am trying to do what I think is a fairly simple task to authenticate a user on my server. I am using AsyncTask as a private subclass of my Activity, however when I try to populate the user object after authenticating it keeps setting it to null. Is there something strange in how the onPostExecute() method is called that is causing this? I originally had the AsyncTask as its own class but ran into the same problem, so I am try to solve this using a private subclass.

When you do a Thread.currentThread().getId(), is the resulting thread id scoped per process or scoped to the current Activity/Service?

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).

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)?

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.
