[Q] Memory management in Android - Galaxy Y GT-S5360 General

does uninstalling an application without clearing its cache and data automatically clears it?
I know that cache can be cleared, want to know about the data of the application

i don't know if it's deteled or not, but data from your old installed application cannot be access by your new installed application, even if they from same version. but, update does not remove your data.

then the data keeps stacking up and consumes more space, isn't there any way to clear the space used by the stranded app data?

cannot be access, can be means it's already gone

they are deleted if you uninstall them with normal way, except the additional data in sdcard. if you have titanium backup, they have 'delete orphan data' option.

Installing custom roms and "low on memory" warning

I decided to try my first custom ROM... (installing virtous) and have a few questions/issues:
1) I started with a Nandroid backup.
2) I did a full titanium backup
3) I used ROM manager to install Virtous (did a full system swipe)...
Ok.. here is where I am having my issues
After the install, I went back to the marketplace and installed titanium backup.
What option should I restore? I would like to get all the widgets and data restored. I tried restore all apps+system data but I am wondering if that is reinstalling the bloatware that virtous removed. If so, what are the correct options in Titanium backup I should use?
Next, I tried to reinstall everything but I got that dreaded low on storage and then out of storage space error. My phone has lots of storage both internal and on the SD card - so the restore (I am guessing) failed at some indeterminate point. Most of my widgets were not loading properly (beautiful widget, pure calendar, multi-icon etc) after the attempted restore.
Regardless, even if I clean-up the widgets, the low memory message persisted so I was left with no choice but to revert to my previous nandroid backup .
So... how do you install a custom rom and easily reestablish your previous state/settings without getting the low/ out of storage warning?
Also, one of my goals is to get a deodexed rom so I can install custom themes (e.g., battery mods, etc). Can I just flash the deodexed stock rom over my current rom (I did not understand deodexed when I first upgraded to froyo) without having to do a swipe? Will I run into any issues?
Thanks
I tried again with less apps/ data and still have no luck.
I did a restore all apps and system data from titanium, got a low storage than out of storage error (the phone has over 60% of its storage available so I know I am nowhere near close to actually using all the storage).
When titanium completed, most apps forced close (gmail, rom manager, etc) so I assume the storage error is impacting the restore.
Back to my nandroid backup again.
If I am running stock Froyo, can I just flash a new sense based froyo without wiping? (trying to find a way to experiment and really want to get a deodexed rom installed)
When new ROM is flashed, in TB, try reinstalling only user apps, not system apps.
Why?
The new ROM you flash and the ROM you are coming from should both have system apps already in them, so why reinstall system apps from the old ROM that most likely exist in the new ROM?
But how do I reestablish the previous settings? Or do I have to reconfigure all my accounts, etc each time I install a new rom.
Thanks
Me too. How to correct?
uncommon 1.1 on my phone is doing same thing. 1.0 had no problem.
Just a theory as I haven't tried to install another ROM...
I noticed the touchdown data file on my phone was quite big (>70mb) - it appears that when touchdown's data file gets very large, the message appears more often (looks likes there is a bug in Android with large data-sets). I cleared touchdown's data and resynced which shrunk the data file to ~12mb. I reinstalled all the apps I removed to try and eliminate the memory error and so far have been running smoothly.
When I have some time, I am going to try another ROM and see if I can restore without any storage issues. I still am curious how everyone resets their settings from ROM to ROM (or do they manually configure everything each time)
After poking around in astro file manager, contacts(cross-linked mess), and uninstalling some rarely used programs all to no avail......
I fixed my "low on program memory" notification by emptying my deleted items in the mail app- a hotmail account that is rarely used.

To be on the safe side, just reinstall only apps, with or without data. There is no real point in wiping days, and yet reinstalling system apps and data. Kind of defeats the purpose. And yes, manually add accounts. Takes more time, but minimizes conflicts. Shouldn't take more than 30 minutes, which is a small price to pay to eliminate potential headaches.

I've run into this as well. In fact it was the original reason I decided to move forward with rooting my phone since I had to wipe it anyway. Has anyone looked into what program monitors this and flags the error? Is memory not being reported correctly, or is there a tolerance that maybe we need to tweak in the code somewhere?

[Q] Cache & Data

So, my GVoice app stopped working about a week ago. It would just crash on load. I went to clear the cache for it, and it was at 1.17GB. It wouldn't clear, I couldn't delete it with temproot. I renamed the folder, and that fixed it. The data is still there though.
The next day I went into my app management, and my browser, facebook, and a couple other apps have around 500-800MB. Again, I hit clear data/clear cache, it doesn't give me an error, but it also doesn't clear it.
Any idea whats going on? This happening to anyone else? I have run the cache cleaner from recovery as well. I just updated tot he new OTA, problem is still there. Everything seems to run fine though.
Sounds like something you did in one of your applications or in the settings is "Protecting" the cache. My best suggestion when all else fails is backup using titanium backup and then do a restore to factory settings and data in both bootloader and in recovery. Backup the sd card and wipe it as well, then just put personal data back to your sd card and restore with titanium, and all problems should be resolved

[Q] App suddenly disappear!

I have a few apps suddenly disappear when I try to install it back it is like updating the app saying all data will save but the app just won't install. I check under data the app's data still exist but when I delete those data hoping the app will install again but just won't work. Is there a way to fully remove app's data & everything so I can install the app again?

Love ur Desire and Prevent Lags

Lag is typically a result of Android working really hard to do all the things you want at the same time. You may be right that an application may be hogging the CPU or even the RAM. Try to keep the number of applications/processes you do to a minimum (e.g load a web page, while sending an email, while opening contacts, etc.).
If you want to attempt to resolve the problem let's first assume that it's an application that's causing the problem.
Go to Settings (from Home Screen) --> about phone --> and check to see if any applications are on the list. If the application has a decent amount of battery usage from it (>5%) you may want to investigate the app further.
Then go to Applications (from settings) --> running services. This will let you know what apps have been stored in memory (RAM) and how much space they're taking up. When an application takes up more RAM then it should, it can cause our phone to work harder to get rid of apps not in use (this is how Android multi-tasks).
Ok let's assume this isn't an apps fault it may be time to clean your system cache. Have you ever noticed when you get a new computer, it's super fast, but as the years go on, your PC gets slower and slower. Sometimes things get stored in a cache which can slow down the system. To clear the cache on your android all you have to do is reset your phone to factory defaults. WARNING THIS WILL DELETE ALL OF YOUR APPLICATIONS you can of course re-download them, however it's not guaranteed that any of the information you have saved in the apps will persist. Anything saved on your SD card will remain unaffected.
Once you get everything downloaded and back to normal, you should notice your phone is pretty zippy again. However reseting your phone can be a pain and should only be done if you really can't pinpoint an application(s) that is responsible.

This is wrong my friend, you can clear cache from recovery and it does nothing to apps installed. No need to wipe phone.
Yep iv`e just cleared /system, /boot, cleared cache and Dalvik cache, flashed AIO 3.0.4 and all my apps are still there.
I do find stopping certain apps (which i rarely use) after boot does help a tad...

No.
When you go from 2.x to 3.x you need to perform a full wipe. Just system cache and dalvik cache is not good enough.
You can, however, sync your phone with google, make a titanium backup, use the app backup/restore scripts from InsertCoin (search for them) before and after flashing the new ROM, in order to minimize the amount of setup you have to do afterwards.

"Other" under app storage takes a lot of space

Hi all.
After trying to install some apps, I recieved messages regarding full storage, preventing me from installing the apps that I wanted, although I had over 200mb available under the app storage!
So I downloaded several cleanup apps and deleted some old apps, but still in the "other" section under app storage, there is 5GB of unknown data (screenshot attached).
I've tried finding out what eating my storage space using some disk mapping apps, but hasn't been able to find out what it is (when I map the app storage, it only shows the apps themselves and the free storage, and not the 5GB).
I'm guessing maybe some of it includes the system data, but didn't think that it will take that much storage space, and also if it is system data, it's weird to me that it's under the app storage section.
I also tried googling it up and looking it up in the forums, and I did find several people having the same situation, although no solution found.
Please note that I'm not rooted.
I would be really glad if someone knows what's causing this, and if there is a solution.
Thanks!
Try to backup your data and then restore to the default settings
Not really

This doesn't fix anything. This was also the advice of the HTC support. Unfortunately they also don't know that a factory reset will not clear that space.
Minimal "Other" will take a little under 5 GB. So don't reset for nothing.
Now i just rooted my HOX and still looking into this (playing with link2SD, might be a fix).
Apps are installed under /data and has a total capacity of 2.11 GB
I have the same problem on my phone. Any "fix" for this, other then factory reset?
(I have the latest update available, running stock os.
