Android :: Why Dont Android Applications Provide An Exit Option? stackoverflow.com

Is there something in the Android developer guidelines that disuades developers from providing the option to "exit" (stop running) an application from within the application itself? I love multitasking and all but it's not clear to me why: the vast majority of apps don't have their own Exit functions and hence just keep running forever don't give you a choice about running when you turn on the phone - they just do by default Both of these things lead to memory usage constantly increasing and your device running with this performance burden all of the time despite the fact that you may only want certain apps to run some of the time.

Clearing Data Cache (Non-Programatically)? www.sitepoint.com

I use data caching quite liberally in my .NET application. However, when debugging I often need to clear the data cache for testing purposes, such as when I change something at a lower-layer that I need to re-verify at the UI-level. Is there any way to clear the data cache without actually doing so programmatically, maybe through Visual Studio? I imagine I could place a button in an administrative area of my application, when clicked, would clear all data cache being used by the application, but is that essentially the only other option besides just waiting for the cache expiration timer to expire?

HTC Incredible :: Possible Solution For "low On Space" Notification androidforums.com

A FACTORY RESET is not an option for most people so I've been looking elsewhere for solutions to this annoying notification memory problem. My research has shown me that this error doesn't appear to be the same for everyone. Some people have a problem with the HTC mail app (better settings below) Some people have a problem with the internet browser cache. Some people have a problem with the Peep cache. Some people have too many messages- have to delete Some people have an insanely large call history- have to delete HTC MAIL SETTINGS- these settings changes had a short term affect (one week)SETTING 1 MAIL>Menu>more>Settings>General settings>Temporary attachment storage> SD card SETTING 2 Send & receive> mail size limit> no limit My possible solution- hopefully long term Clear the contact storage cache SETTINGS>APPLICATIONS>MANAGE APPLICATIONS>CONTACT STORAGE>clear cache I'm curious if this solution is longterm or not.

Flex :: Where Are Swf Files Kept After Clearing Browser Cache stackoverflow.com

If I am on a flash heavy website, and I clear my browser cache, the site continues to function. Chances are the entire swf is not loaded into flash's active memory at the time I clear the browser cache (especially for sites that use large rsl libraries such as papervision3d). I can verify this with flash-builder's profiling tools. So, where are the swf libraries kept on disk (or in memory somewhere else?) which allow the site to continue to function?

Which technique is more efficient and optimal in performance and security? and is SQLCache dependency related to SQL database only or can be applicable to other databases like Oracle?

The free memory has gone down by around 15 to 20 MB. Is there some sort of file management issue that "wastes" memory on the Blackberry?

Still, free memory remains below 70 MB.

BB Tour 9630 :: Clear Pushed Content In Browser To 0.0 KB - But Its 0.7-1.4 KB At Reopening Browser forums.crackberry.com

But I dont really recall this on my previous tour. My memory seems to be leaking, but no apps are open other than the default ones. I've cleared the logs and i cleared the browser cache. Now heres my question, every time I clear the pushed content in the browser, it says 0.0 KB, like it should. Now every time I reopen the browser and recheck the cache and all that, i have between 0.7-1.4 KB of pushed content there again. However the content cache and cookie cache are at 0.0 KB and 0 respectively. And i have no subscriptions to anything to cause any pushed content to come, so idk if this is normal or if it isnt. But yeah, I was just wondering because my memory gets smaller, not by much, but it does, and I was wondering if that was the culprit?

Hmmm,,I just looking at applications mem usage, on my Task Manager,And noticed, all of the programs memory usage rises, as their are in use longer,So, i was wondering,Since unloading the app, clears the usage, etc (When done properly)Is there a way to clear the usage (of old data) whilst its in use,Its mainly browsers that keep the MEGA usage (IE does too, but thats another point), So jst wondering <edit>Or, How do i Get the memory usage of my application?If my app reaches something like 50, 000 KB (Leave it on for like 4/5 hours at a time, and that)I will make a "subRoutine" to re-load the application (since it normally fix's memory loss etc)TNX

.NET Application Stopping Event? stackoverflow.com

I have a ASP.NET application which implements a custom in-memory cache. I'm using this as opposed to ASP.NET's caching mechanism as I needed a more complex way to handle what to drop from the cache. Part of this custom cache is a separate thread which occasionally searches for data to drop from the cache whenever it gets too large. What I need to do is signal this cache maintenance thread to stop whenever the ASP.NET application 'exits'. I guess this basically amounts to when the web site is stopped in IIS. Is there a pre-existing event I can utilise to do this?

Samsung Galaxy S II :: What Is Happening When "Clear Memory" Is Clicked samsunggalaxysforums.com

In the task manager, if I click "Clear Memory" under RAM tab, it said more than 10 apps closed. But when I click the same button after few mins, it said the same number of application closed again.Actually which applications got closed when I clicked the Clear button first time, and how those apps occupied the memory once again, how do I ensure, my RAM is not used by unused/unwanted apps, where can I see the which applications are using how much memory?

Android :: All Static�s Variables Retaining Values When Launching Again groups.google.com

I have been facing problems to manage statics variables used in my android application. If we exit the application against a particular event (touch or key event -which is must for my app), all the statics variables are retaining the values when I am launching it again. I am invoking Activity.finish() method for termination . I know there is a collection type class available called Bundle and we can use it to save the states of all the statics and get those back when again creating the same activity during relaunch, but it would be a hard task if we want to port some j2me applications to Android because of having thousands of statics variables. Is there any way to kill the application completely including all the statics variable used there? I tried with System.exit(0) and it works well for Android G1 and G2 (tested in firmware 1.6). But in Android Robyn (prototype) the same causes a major defect ("Activity not responding" popup apears just after exit) and I came to know from android dev forum that calling System.exit(0) is not recommended for termination of an activity.

Asp.net - Using RavenDB As A Persistent Cache stackoverflow.com

I have currently have a web application that caches a large amount of data (several hundred thousand entries) in memory for quick lookup and then in SQL Server as a persistent cache. Basically the information consists of geocodes of addresses where the geocode is retrieved via a remote web service which takes time if needed to be called continuously rather than cached. Would using RavenDB (or other suggestions) be a better way of caching this information in a persistent store in terms of both speed and memory?

Strange Error www.codeguru.com

Hello allI developed an application with vb6 an i got a strange error at exit, but only in one situation: if i run the application from VB6 IDE it works and i can exit witout any errors. if i make the executable and i run the application everything works ok, but at unload i get this error: The instruction at "0x66023287" referenced memory at "0x00000000". The memory could not be read.My question is: why i get that error only when i start the application from the executable and when i runt it from vb6 IDE i don't get it???Thanks a lot

Android :: Activity Of Killed Process Still Visible In List After Home Pressed stackoverflow.com

like many others, I want to kill my Android application on "exit" button. Really kill, not just move to background and stop all active code. (I know very well that Android does not like it.) I found Process.killProcess(Process.myPid()); and System.exit(0) which both work fine (I have no problem with activity stack, the "exit" button is in my base Activity.). But there is a problem. When I kill my process and I am back in the shell, I press [Home] button. It shows list of applications that are on the background including my application which has been killed. Is there a way how to do both: 1) kill the process and 2) remove it from the Android application list that is shown after user presses [Home] button? Thanks for all replays (with the exception of that stupid "you should not exit applications explicitly on Android"

Motorola Droid :: Way To Clear Cache For Weather Widget? androidforums.com

Android :: Cant Clear Cache On Some Apps androidforums.com

I have a couple apps I have noticed when I open a file it must cache the file internally, but gives me no way to clear. For example Zumodrive and repligo reader both will show 20+mb in my settings, but clear cache is greyed out and shows 0mb. However when I delete these apps and reinstall them, I get all that internal memory back. I am running a rooted Nexus One.

State Management :: Session And Application Cache Items Disappear? forums.asp.net

i've been coding an asp.net site using VS2005 for about one month. my site uses both application cache and session cache to save data. the syntax i use for application cache is : HttpApplicationState appState = Application; appState["someKey"] = "somevalue"; and for session cache i use : HttpContext.Current.Session["someKey"] = "Somevalue"; my site is deployed on three standalone servers - each server runs a diffrent instance of the site. two of the servers work just fine, the third has a stange problem - and also has the least free memory space. in this server items start dissapearing from both the session and application cache - note that i set no expiration date to the cache items. does anyone know why this could happen? seems to me there is perhaps some memory limit for cached items setting that i am missing.

Does any one know a code to clear excels cache or memory? I have used cutcopymode = false but that does not do the trick.

Nokia :: N85 Phone / Memory Full discussions.europe.nokia.com

I've seen people discuss this problem before, but no answer is ever found.I have 50 MB memory free in my N85; just in case, I cleared browser cache, cleared out old messages, old email, etc. (and, in any case, I keep ALL such things on the memory card, not in main memory, so it shouldn't matter).I have phone memory coming out of my ears.BUT... whenever I I go to the phone log, and try to look at "missed messages", it says "Log: Memory Full: Close some applications and try again".I am running almost no apps at the time, and the phone reports lots of free memory, both on the phone and on the card.This appears to be a long-time S60 bug that nobody has ever found a solution to.Anybody have a solution that I don' t know about, aside from trying to reset the phone to factory defaults or reformat?

Android :: Clear Maps History Programmatically? stackoverflow.com

I want to programmatically clear the history of the android maps (and navigation) application. I know there is a way to clear the browser history via Browser.clearSearches(getContentResolver()); And the corresponding permission: com.android.browser.permission.WRITE_HISTORY_BOOKMARKS and this works fine (2.2.). I couldn't find any way to clear the Maps-History though. Clearing the google/history online doesn't help either. There are some apps in the market that promote to do that, so there must be an API for it, but i really couldn't find it yet. I also messed around a bit with CLEAR_APP_CACHE and CLEAR_APP_USER_DATA but seems like they are signed/root-only permissions and delte too much anyways.

HTC Magic :: Memory Leak - Phone Extremely Slow androidforums.com

I don't know if it's just me, but my HTC Magic becomes very laggy after few minutes of use. Cleaning the Market and Navigator's cache and stopping all background tasks with TaskPanel Lite helps, but then after few minutes of use it becomes extremely laggy again. Don't know what to do. Note: When I clear all the background tasks and cache, TaskPanel indicates that the phone available memory is from 20 -> 24mb (seems to be to few) but after some minutes of use it goes to 3 -> 5 mb of available memory.

Red Hat / Fedora :: "Unknown Error 513 In Pthread_create After Several Hours Of Running A Gstrea? www.linuxforums.org

I am using Gstreamer for creating one of my video streaming application. My application creates multimedia session and then stream around 200 video sessions (a very processor intensive job).In doing so, the no. of threads created is around 1500 and I have given around 1536 KB as my stack size for each of these threads. I have one Quadcore(intel Xeon) system of around 8 GB of RAM(64 bit) with RHEL 5.5(kernel - 2.6.18-92.el5). After few hours of testing I see that my overall memory(RAM) is eating up. I did checked the memory and I saw that my cache size is growing. So far so good, as I can understand that system does cache instead of leaving some RAM free. My problem comes, when I see that after almost 20-25 hours of testing, RAM is continuously being eaten up and maximum part of that is going into cache. If I leave the system for few more hours I see whole of my memory is consumed up and now my swap started getting used. If I check the cache now, I clearly see most of RAM is now in form of cache. I still didn�t stop my application and allowed it run for few more hours and after sometime I see that process give segmentation fault while creating the pthread (create_pthread::unknown error 513).I also tried to observe the �core� file of application created in this way , but it doesn�t� show anything. One thing I must mention that, in �top� I see almost constant values of resident memory, virtual memory and shared memory. There is no increase of memory usage here. So here I can assume that my application is not leaking the memory. I also observed that if I kill my application any time during this, the memory doesn�t go into free pool. Anyone, here can give any pointer for this kind of behavior. Is it can be because of some kernel BUG which is not freeing the memory to application usage.
