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?

Caching Over Distributed Application On Servers? stackoverflow.com

I have tried SQLCache dependency before and i have heard about Memcached, Velocity and Enterprise cache so which one will be more efficient and optimal for this case? and i have another solution to create webservice method on each application and when the cache is cleared in one application it will request the webservice method on the other application to clear cache there. 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? Note: I am using load balancer to distribute requests coming for the application among the 2 server

BB Bold 9700 :: Applications Taking Up Too Much Memory? forums.crackberry.com

Is there a direct relationship between the size of the applications being loaded on the Blackberry and the amount of free memory? I had around 90 MB of free space on the device, and then proceeded to load a handful of applications. I haven't done the exact math, but I think I loaded around 5 MB of applications. 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? I have tried all the usual tricks to free up memory - running Memory Cleaner, running Memory Booster, clearing all cached items in various applications, pulling the battery. Still, free memory remains below 70 MB.

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?

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?

At the moment it appears to be on the phone memory - which is filling up rapidly - and i've got 23Gb spare on the mass memory, would be much better to have the cache there (rather than clearing it every so often)

My wifi connection to my ipad2 is getting slower and slower, and is becoming more noticeable when connecting to the apps store. Could it be something to do with the cache or memory?

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.

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.

Web Forms :: Caching When Cached Size Exceed Memory Size? forums.asp.net

As I know, by default Cache is stored in the memory and to the disk at the same time DiskCacheable=true).When the cached response is removed from the output cache due to memory pressure, it still remains on disk allowing a much larger set of pages to be cached. In addition, disk cached pages survive application restarts. And this is already in ASP.NET 2.0.I dont't know in which order the caches are removed from the memory and readen from disk instead? I would like to achive, that caches with the minimal trafic, or the longest last used, would be removed first from the memory. Is there some settings to do that, or even by default works that way?

.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?

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?

Caching User Control And Clearing That Cache Programmatically? stackoverflow.com

I'm trying to cache user controls and on some pages i want to cache single objects. There are multiple ways of implementing caching, and my head is breaking over it. The way I see the caching options now: You have the PartialCaching option which is set to cache the control for 30 minutes, and after that it clears itself... You have the varyByParam to identity the page by its querystring paramaters... or other vary options But i just cant find an appropriate way to add caching to a control, and be able to clear the caching programmatically when i update one of the objects used in the control from the backend. You can do HttpContext.Current.Cache.Insert(), which accepts a key on which you can destroy the caching item later by using remove... This can save objects in cache but can you use options like varyByParam? My questions are burnt down to two: Is there a way to clear the caching on specific user controls from the code? If yes, can this be done according to the varyby options? How would the object caching respond to logged in users or anonymous users using Insert()? EDIT: I'm caching multiple things.... And I'm really flabbergasted in which choice to make referring to caching. Can the Cache.Insert be varied by Parameters? The main problem is peopling editing things from the backend, which needs to trigger an event that reinstantiates or clears all caching items referring that object.

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.

BB Curve 83xx :: Any Way To Switch Storage To SD? forums.crackberry.com

I've recently come back to the Blackberry product line from a WM6 device, and I'm having to learn how to do some tweaking to get the device to work with my usage. Right now, my pain point seems to be the lack of storage memory on the device's main memory and I would like it to use the SD Card I've put in more heavily. On WM5/6 you can pretty much hack everything to use the storage card, including document folders, browser cache, email storage, etc. Right now, I have to remove one application to install another, and I'm running the minimum email storage (15 days), cleared cache, etc and its a pain. Does anyone have any recommendations and possibly links to guides that explain how to get the device to use the storage card and not the physical memory for many of the more heavier use functions such as email, browser downloads, browser cache, etc?

State Management :: Deleting Data In Cache Memory? forums.asp.net

I have a webpage which displays some data along with a banner. The banner image is stored in the database with parameters "Pagename" and "form". The application has been coded in such a way that when the page loads , a function checks for the banner in cache memory first with the parameters "pagename" and "form". It the banner does not exist, the new banner is retrieved from the database and is added to the cache memory. Next time when the same page is called, the banner is displayed from the cache memory avoiding the DB to be hit everything to get the banner. Now, I do not want a specific banner to be displayed on the page. I have removed that banner from the DB but the banner still gets displayed as this banner is still there in the cache memory. Is there any way to delete the banner which exists in cache memory without making any code changes?

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"

General :: Deleted Files - Free Memory Didn't Increase? forums.androidcentral.com

I have a Samsung Galaxy Tab 7.7, though I've seen people post about the problem with other devices, so I think this is an "Android" problem. I just got the tablet about a week ago, but this is by no means my first tablet, or Android device. I don't want to root or anything -- I'm happy with the stock device, along with the apps I install and the files I download to it. I've got a 64GB microSD card (also Samsung brand), formatted as FAT32, and it works just fine. So, I was filling the tablet up with media files, and I was downloading video files to it. It has 16GB of internal memory, and I figured I would fill up a bit more than half of that with some of my bigger video files. I downloaded a few files, then figured I could download a bit more, and downloaded a couple more. Then I looked at the free memory, and it was down to 3GB free -- "whoops, too much." So, I deleted the two files, which were about 3GB together. AND THE FREE MEMORY DIDN'T INCREASE ONE BIT. And I've been trying to "get my memory back," ever since. So, here are a couple of screen shots I can show you: First up is the usual Storage view: OK, so what the heck is that 3.36GB in "Miscellaneous files?" That's roughly the size of the two files I deleted, so let's go in and take a closer look: So, it's in the "System memory" up at the top. So, what is "System memory," and what could be taking up that kind of space? Some kind of "cache" that kept the two files I deleted in memory, perhaps? So, from here, it's pretty simple: What is in that "System memory," and how do I clear it out? It's NOT any "application cache" -- I've used apps that clean out the application cache, but they didn't touch this "System memory." I've tried the "Wipe cache partition" from the recovery menu, and that didn't touch this "System memory." I sure haven't seen any apps that can do it. Or, is having a big wad of whatever in the "System memory" pretty typical, and thus it doesn't have anything to do with the fact I deleted those files and the free memory didn't increase? I doubt that, because I've seen quite a few screen shots of the Miscellaneous files screens that other folks have posted, and I have NEVER seen a "System memory" item at the top like I have. At this point, I'm expecting that I'm going to have to do a full reset to the factory build, just to free up this big wad of unused memory. Of course, I would rather not do that, but if I'm going to do it, it would be "better sooner than later."

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.

Sprint HTC Hero :: Need To Make My Hero Faster? androidforums.com

Well, I was playing with my phone today and I might have made it a faster in a few minutes. This is what I did Home - Menu -settings - Applications - Manage Applications. In this menu it shows how much memory each program is using (?), not really sure, but if you click on the program you can clear out the cache and also clear the data of the program. I cleared out all of the data and cache from the programs that I dont use (sprint TV, NFL crap, footprints, etc...). It seems like its running faster, might help for people that have been using the phone for a long time and have a build up of data just sitting there doing nothing? Let me know if this works for anyone else!

Android :: OutOfMemory While Editing XML In Eclipse stackoverflow.com

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.
