Apps keep auto-closing.

I've tried many froyo roms and cm7 and apps don't stay open. If I switch from an app for a couple of minutes and then come back to it, it's closed and has to reopen.

Are you sure they're apps that are supposed to save their state? Are you running any sort of task killer or memory "enhancing" software? Do the roms you use have any sort of memory optimization built in?

Android used a similar way of memory management to Windows Mobile.
When your memory usage reaches a level, the system starts to kill background apps. I think there are 4 tiers of killing...

Whats Best way to free up the ram???

Whats best way to free up the more ram? I have root and froze the safe stuff. The lowest I can get free is about 185MB / 328MB.

Rooting and freezing apps doesn't give you more RAM, since there is only 512MB of RAM and the OS takes part of that to run.
You can free up internal app storage space, by deleting bloatware, or cut/paste the bloatware into a folder on the SDcard (I call mine VZWBloat) and that will save you space.
You can run a task killer to kill off apps that you don't need but you have to be careful, Android does need certain apps to be available in the background and it will just reopen automatically and that will put them into a cycle and drain the battery.

Freeing up that much RAM is probably detrimental to the overall efficacy of the memory management system, I've never seen mine at 185MB, and if I did I'd worry something was wrong.
If you really want to free up more RAM, for no benefit whatsoever, use something like Advanced Task Killer and set it to allow killing of the lowest level processes it can, then kill everything. Bam, tons of free'd up RAM. Again, this has pretty much no benefit whatsoever and for a short time will probably make your phone more sluggish and slow.

In Android (Linux) free memory is considered wasted memory.
That said, I remember on my galaxy S that the phone ran snappier when I tweaked the memory management of the phone.
Task killers are generally considered a bad idea on android, so I would avoid using one of them to free up memory. However, there is a poorly named app called auto killer that is actually just an interface to tweaking androids built and memory management. I recommend giving it a try, here's a link: http://market.android.com/details?id=com.rs.autokiller
Note that it is not a task killer per se, it is just a tweak for android phone memory management schemes.
I haven't used it on my droid charge yet, but play with the settings maybe starting with aggressive. Good luck and let us know how it works for you.

I don't have my phone with me right now, but you need to make the folder read/write and then hit menu and multi-select or select multiple. This thread http://forum.xda-developers.com/showthread.php?t=1082588 shows what is ok to freeze, but I am not familiar enough with those to say you can remove all of them. Typically I would look for the Verizon specific apps, games like lets gold, guitar hero etc. If you remove anything related to touch wiz (widgets) you need to remove both of the associated files. I am pulling this from memory on my previous TB.
These are the ones I recognize, but the others in that long list I would like to see better clarification of what they are and how they are tied into the TouchWiz UI so we don't get errors. Please exercise caution when doing this.

BY FAR.... BAR NONE.... The best way to free up memory and keep it free without messing with task killers is to use a program called startup auditor. This app prevents apps from starting up automatically on startup and throughtout the day without interfering with normal app processes. You can shut down or enable any app you want.
Even cooler, if you select the option menu and hit disable all, it only disables programs that won't interfere with the phone operation so it knows which apk's are critical for phone integrity. PRETTY COOL!!!

I wasn't really condoning the use of task killers. I disagree with them 99% of the time (there are some edge cases). I just gave the OP an option if he really, really wanted to for no reason whatsoever.

@OP: I would recommend leaving the pasture gate open.

There is an app called Greenify. Its available on Play store.
Just check it out.
It also helps to maintain the juice of the battery.. !!

To Free Ram
A more easy way to delete a minimum of 1gb of space which by doing so also frees up ram is to delete the dump state log cat. See every time your device has an error or force close issue, date is collected / written to the log file and this can take up ane enormous amount of space which when space is low also means your device user more ram. To do this go to your dial pad and type in *#9900#
This will automatically brings up options and then just choose to delete the dump state/log cat. Let it clear for a few minutes and that's it's. Try seeing how much space you have before and after and you'll realise this is a blessing.

Memory clearing widget?

Hey guys, just looking to see if an app exists.
I use SuperBox to 'clear/free' my memory. I like to keep it at around 230MBs free at all times or so. My question is this: is there an app that exists that does this same thing, in a one-click widget form? Someting I can set as a 1x1 icon on one of my screens to just tap and it will clear the memory? That would be quite convenient, as right now I need to open up SuperBox, navigate to the Memory pane, then click 'Clear Memory'.
Thanks for the suggestions!

es taskmanager.
By default it will clear all apps in the list except a few which are hidden.
You can unhide apps/services by accessing the options menu.
You can also set a kill list only, so when you tap the widget it will only kill apps in your kill list.

Clearing memory doesn't really help your phone to much, it's just gonna restore in a second.

task killers as you all should know are not healthy for android phones. linux pools memory. it manages it on its own.
Here's a good article on this: Android Task Killers Explained: What They Do and Why You Shouldn’t Use Them
In Android, processes and Applications are two different things. An app can stay "running" in the background without any processes eating up your phone's resources. Android keeps the app in its memory so it launches more quickly and returns to its prior state. When your phone runs out of memory, Android will automatically start killing tasks on its own, starting with ones that you haven't used in awhile.
The problem is that Android uses RAM differently than, say, Windows. On Android, having your RAM nearly full is a good thing. It means that when you relaunch an app you've previously opened, the app launches quickly and returns to its previous state. So while Android actually uses RAM efficiently, most users see that their RAM is full and assume that's what's slowing down their phone. In reality, your CPU—which is only used by apps that are actually active—is almost always the bottleneck.

Thus, killing all but the essential apps (or telling Android to kill apps more aggressively with the "autokill" feature) is generally unnecessary. Furthermore, it's actually possible that this will worsen your phone's performance and battery life. Whether you're manually killing apps all the time or telling the task killer to aggressively remove apps from your memory, you're actually using CPU cycles when you otherwise wouldn't—killing apps that aren't doing anything in the first place.
In fact, some of the processes related to those apps will actually start right back up, further draining your CPU. If they don't, killing those processes can cause other sorts of problems—alarms don't go off, you don't receive text messages, or other related apps may force close without warning. All in all, you're usually better off letting your phone work as intended—especially if you're more of a casual user. In these instances, a task killer causes more problems than it solves.

Task killers are useless on anything newer then android 2.1. All they'll do is break some apps. I haven't used these on my phones and don't have issues. If your phone is slow its due to a rogue app.
Edit: somehow missed Norflynns post. That link sums it up perfectly.

^^^ What they said
It's ok to have a task manager to keep an eye on processes and kill troublesome ones, but no point in constantly killing all your processes.

Deleting apps--are there residual files that slow down Android over time?

Deleting apps--are there residual files that slow down Android over time?
On Windows, it is expected that PC users reformat every 6 months because their computers get inevitably slow down as a result of registries left over after uninstalling program as well as left over cache, etc.
Do Android users suffer a similar fate? Or is it clearcut that all apps (what about system apps?) and all their settings and related files are located in a single folder? Will uninstalling an app without any third-party app remove all traces of an app? Will it be as clean as an app dedicated to this purpose like Titanium Backup?
Lastly, are there ever any problems created by apps that claim they can move apps to an SD card? Maybe some files are left behind and not everything is transferred?
Thanks.

I don't know if residual files can slow down your android, but if you are concerned about these, you can download "Clean Master" from the playstore. This app has a utility that scans your phone for residual files, then you can choose what to do with them; keep or delete.

Yea, I have that app and it was why I asked this question. On an unrelated note:
The app Clean Master claims it can extend battery life and device performance by killing apps--even offering a button to kill all apps. I thought killing apps was unnecessary since Android does this automatically when RAM is full and that killing apps manually actually drains battery life. What's the deal? Is swiping an app away from the Recent Apps List the same as killing an app? I currently do this often because the list is usually packed.

swiping away the apps counts as closing the apps. as far as i know, there are also background processes running after you swipe away the apps. My recommendation is greenify ( http://forum.xda-developers.com/showthread.php?t=2155737 ). this app will hibernate your open apps closing the background processes with them. then only thing is that... it requires root.

How to limit RAM usage per application

Is there a way to set hard limits on how much RAM individual Android apps can use? Seems most apps are greedy, and I'm running out of RAM, which makes switching between the apps I am currently using slow.

I used Titanium Backup to freeze all apps I don't use frequently, and now my ram usage is down to about 50%, where it used to be around 90%.
I also use an app called Auto Memory Manager, which controls Android's own memory management. You can tell it to free memory sooner than later, for different types of memory categories. But what made the most difference was freezing apps with Titanium Backup.
I'd still like to know if there is a memory policing app, but the aforementioned are good solutions.
