I'm no developer, scripter, or any type of person with a thorough understanding of software but I will try to offer a suggestion to those who wish to give me the time of day.
After flashing countless ROMs looking for the fastest and most simple platform to use everyday I have discovered a few things that might help if people agree with me or not. After loading every ROM and first booting... I realize that Advanced Task Manager shows the available system memory at less than half and i haven't even started running apps or installing programs yet. Processes start when the phone boots up that are running in background (asleep but still using system resources) and i believe that a fair percentage of them are not required by the everyday user.
Why is Alarm Clock running in the background when i haven't started it? Why is Email client running and i haven't setup exchange or an email account? Messaging, Maps, Settings, Gallery, these all start up without being physically executed and are using resources. If there is a reason for them to be there like not being able to receive SMS if Messaging is not running, then that is fine and im an idiot... But if there is no need to startup the application from boot then why do it?
My second point is when packages are installed as the ROM is flashed, they cant be uninstalled right? well what if we didnt want tethering apps and facebook apps and proprietary software (Moto apps)? Most of these are available in the market and if not, a 5 min Google search will find an .apk on the net anyway.
So how about a bare bones install with the essentials and nothing else? Youtube, Phone, Messaging, Gmail, Contacts, MT Browser , Maps, Calculator... then anything else can be added at the users will.
If anyone else has something to say... or prove me wrong, then please elaborate.
If you delete the alarm clock task, you're likely to sleep into the morning as the alarm won't go off in the morning. Mail is probably needed for pop3 checks (I rely on my google account).
Anyway, I usualy remove the apps widgets from the ZIP which I don't need prior to flashing, resulting in a liter ROM and less processes which I don't need running in background.
I also used to add the apps I use (ASTRO...) directly into /system/app prior to flashing, putting them to the system partition and ... at this point I am not sure.... this leaves one with more space (internal memory) accessible for apps from market (if you do not use APP2SD). I stopped however doing so, as this makes ROM upgrading painful, as you do have to prepare each .zip before flash.
With regard to operating memory you preferably use either Taskkiller or have your systems autokill file optimized as many ROMS do (CursorSense). Refer to http://forum.xda-developers.com/showthread.php?t=622666
I'm not Linux-guy but I know that Android does this to put those programs in memory ASAP because those are usually the first few apps many people use once they boot up their phone -- meaning those apps, when opened, will quickly open and run faster.
Remember, Linux is made to handle all those opened apps and resources; "Unused RAM is useless RAM".

Correct!!
People have to stop comparing Android (linux) with WinMo devices, they handle RAM completely different.

Yes, true.... and well known. However Linux was developped for servers and not mobile phones.
Launching an application into free RAM is slower than pulling it from a suspended state. So much is true.
But first having to free up up RAM (by killing tasks) before launching the application into the freed up RAM is certainly slower than launching into free RAM. Probably that's why guys are tweaking around, as noted in the link of my post above. Also in my opinion the default settings are not optimal, that's why I use tweaked settings. Probably that depends on how you use your phone.
But I agree. Coming from Windows the whole LINUX concept is a f**** nightmare. There are thousands of different methods (Cache/Compcache/ Ext Cache)...
So it's good to have an expert around. Could you please enlight me, whether the system partition is of fixed size or size is been alocated during flashing. In other words, is the Userdata size fixed or depending on the system size? .... and is there a benefit of putting apps to the /system/app as they will go to system parition and I will have more internal storage available?
Thanks in advance.

Your Android Device is divided Into partitions -> (Device memory)
1. Hboot (spl)
2. Radio
3. Data (Where u store ur data apps / passwords / other thing)
4. Cache (temp)
5. System (system dump)
6. Boot (to start the device)
so on
Now partition of memory card is important becoz
1. EXT2/3/4 More Amount of Data Section -> if device memory is less
2. Swap -> To fast up the system
*I m Not best Explaination giving person but i think this is understandable language in which i hav written
I think I side with the OP on this one, I would rather have a rom with less in it and then choose to install Amazon MP3 or whatever by myself. Generally speaking you could argue less apps = better performance, as there will be less happening in the background. That said, I have included Facebook in my rom.

Not really true, Linux is just the kernel and can be ported to anything, it's been in embedded small devices for years and not just installed on servers.

Thank you very much for the feedback! Most appreciated and helps me to improve my general understanding . I find it really hard to come by information, that is not absolutely basic or high level expert.
Thanks again.
Ive got a clock radio that wakes me up... if i have lagging issues with my phone what i do is use advanced task manager to stop all processes im not using (alarm clock, maps, messaging, email, etc) and everything runs fast again.
No use in reboot cause all the apps start again from boot.
ive tried removing zips from rom before flashing... when i goto upgrade the update stops cause of the missing files > incomplete manifest. is this cause you have to re-zip and sign it?
You can either do that and re-sign the zip file.
OR you could just close this thread and use adb to remove things that you dont want from the ROMs.
PS. root explorer also works wonders.

when i try to remove an app from a ZIP it wont let me flash the ROM. even when i replace an app with a newer version renaming it to match the one im replacing, it still doesnt work. what do i have to edit in order to allow the update to go through?
You need to sign the zip file again. Google signing ROMs, its the first thing that pops up.
Force2SD moves user (not system) apps to SD that the OS normally doesn't allow movement of. Needs root and 2.2.
Source code available.
Official release is now in Market. For test versions, click the source code link.
I added apk file size to the display.
By the way, one reason I like this even for apps that can be moved to SD in normal ways is that it does its scan much faster, at least in my configuration, than apps2sd or Settings|Applications.
And I also added an option to move apks back from SD to internal storage.
is it normal that it only shows userapps? eg. maps, facebook etc does not show up on the list

It doesn't show things in the system partition--those shouldn't be taking space away from user apps. Are these apps in the system partition (/system/app)?
yes, they are in the /system/app folder. are you saying that moving those apps to the sd wouldn't count towards free space on hte device? i am looking for a way to move maps to the sd, as it takes up the most space of all the apps that can't be moved.

Right: the /system/app folder is on a separate partition. Normally, apps install in /data.
This seems like a great tool for full wipes prior to loading a new ROM. Then TiBu would only be needed for the app data correct?

Is there something different to "pm setInstallLocation 2"?
Nice app, it also seems to be working on android gingerbread (NAND HD2) 2.3
Edit: Except for widgets. but that's no problem
Great idea. Downloaded. Moved 2 apps to SD, then checked out list for SD to Phone (nothing moved, just looking around) and got a FC. Will keep for a while to check out future updates.
Ideas for future:
-app icons (so you can tell WHICH angry birds app you're moving )
-file size before / after move
-total available space
-multi-select (something that would GREATLY improve the app over settings)
Keep it up!

thanks for the great app

I don't know if it would work. On my Archos 43 when apps are moved to storage, the OS does not include them in packages.xml when it generates a fresh packages.xml after resetting Android. As a result, storage can contain orphan apps after a reset. Of course, if you restore packages.xml from a backup, that should work.
I just back /data up with tar.

Apps that are moved don't get their on-boot notification. If they absolutely need their on-boot notification to function (e.g., apps that start up some service on boot), they won't work. Likewise, input method apps (e.g., Swype) won't be available after a boot, though you might be able to enable it manually afterwards in the Settings. I wouldn't move Android Market. I did move Amazon App Store and AppsLib with no problems, though. I don't know what happens if you move a browser helper, like a pdf viewer or flash--these might need to register on boot or something like that.
See here for more information: http://developer.android.com/guide/appendix/install-location.html
Moreover, it's probably better not to move tiny apps, because apps moved to storage take longer to have their icons show up in the launcher after a boot. I moved most of my apps that are over 200kb.
If an app doesn't work after being moved, just move it back.

0. I wonder about the crash. If you have adb set up and can duplicate the crash in the latest version (I posted 0.10), watch with adb logcat to see where the crash happens and send me the log.
1. App icons will really slow down the application list fetching. Maybe I could include app icons in the list for moving to SD, but the list for moving from SD is very slow.
2. The file size I show is the apk file size. This does not change with the move as far as I know.
3. Total available space shows up in the current version.
4. That's more work than I want to do.
Some more answers and comments;
1. I uploaded version 0.10. This fixes hangs in low memory situations due to the package installed broadcast being sent to all apps. The solution is drastic: as soon as the packagemanager reports success, I kill the thread. This may cause some problems. Let me know if it does. Seems to work fine for me, though. Also, version 0.10 lets you conveniently delete apps right from the list--just do a long-hold on the app, and you get an uninstall option.
2. Force2SD works pretty much like pm setInstallLocation 2, except it moves apps individually, after they were installed. I don't want to set all my apps to install automatically in storage. If you want to duplicate its functionality manually, what it does is: pm install -r -s /data/app/filename.apk
3. I don't really want to spend $25 at this point to register with Android Market. Once my open source astronomy app is done, I'll want to do that, I guess.
4. For people who want icons to tell different versions of Angry Birds apart, I have a simple "solution": just move them all to SD--they're large apks, and you'll save a lot of space. (Actually, they can be moved with the standard OS tools.)
As we know, JB and Kitkat ROMs have gotten much larger than their ICS predecessors. Flashing these and some gapps can easily run our device out of space on the system partition. Some apps will not even be installed, others will have errors. Even some hardware may not work correctly. So the ROMs must be trimmed to fit correctly.
In higher-end devices, they will be 1GB of system space. ROM-builders and chefs tend to dump everything on system as a convenience. Flash the ROM, a load of gapps and one has a complete-functioning system. What could be simpler?
For our oldie-but-goodie, we do not have this luxury. Even with micro-gapps consisting of an old Play/phonesky.apk and some framework will run out of space.
Really, anything not needed to get Android up and running does not need to be on system. There are some additional apps that require extra permissions afforded system apps to work. They need be kept there as well. But the others? Install as user apps. Then let link2sd or such symlink them out of the way (data space runs out too easily on our old phones as well!)
I trim the ROMs to bare metal. Not necessary to be so severe however. I ran ICS for a long time with 3 meg on system with no problems.
What do I remove, keep, etc?
1. /system/usr/srec (speech recognition stuff, most likely no longer in use!) I keep a copy on sd-ext and symlink to there. No problems.
2. Ringtones, alarms, sounds -- most of these have already been trimmed off the ROMs by the devs so I leave what they leave. Want more? Place in similarly name folders on the sdcard and Android will find them.
3. Fonts:
Linux, Android, XDA, are international communities. To save a small bit of space, non-Latin fonts have been removed from recent CM-11 and Omni ROMs. I objected, placed revert request on Jenkins. Raise those voices, folks. Many of us regularly use non-Latin fonts and languages. I keep all the fonts. The fairly large "fallback" font is usually missing on ROMs nowadays. Those using CJK languages or getting a lot of '?' in text should put it back.
4. Apps, apps, apps:
Calendar should be installed from Play. Take off ROM.
I install Apollo, Calculator, CMFilemanager, Cameras, Galleries as user apps. Work fine.
If one does not use live-wallpapers, take their apps off.
If one is using Google Search/Now (must be side-loaded as not fully compatable with our device and will not install from Play), the QuickSearchBox is no longer needed in system.
Google Play Services can be installed as a user app and auto-updates as such anyway. A version of Play, older and smaller the better, apparantly must be on system but the full newer versions should be installed as user apps and will be auto-updated as such.
Flash the tiniest gapps one can. Most all gapps such as Maps, Keep, Hangouts, etc., etc., are installable from Play as user apps.
.
5. Keyboards
The LatinIME with all the languages was ridiculously large. Recent ROMs only have English. There are numerous kbs on Play. One only needs a small kb on system to enter Google account on first start if one wiped data. Do not need swipes, handwriting, voice, dictionaries, etc. Since I do not wipe data, I do not even keep the LatinIME. But better to have a kb on the ROM.
Want swipes and languages without the bloat? Try multiling-o. Whole business is 330k and numerous!! languages install as user apps as well and do not eat up data space. Not quite as good as Swype or Swiftkey but pretty close, very light-weight, and very configurable as well. Note that recent paid link2sd versions can symlink app data as well so one can now have one's Swype or Swiftkey and eat it to
Interest in other's ideas and alternatives!
There is now an app on Play just for installing CM apps! Those include Apollo, CMFilemanger, DSPManager, etc. New there is a "CameraNext" which is NOT Focal. Says might not work. Does on my phone.
Anything available from this app can be made a user app, taken off system, symlinked away by link2sd. If the app is on system now, i.e. Camera, Messaging, et al, do not install from the app. Instead, force stop the app (avoid FCs after moving), link2sd convert to user app, create links. When flashing newer ROMs, trim the apps made user apps off the /system/app/ before flashing.
The weakness of this is that if the apps were upgraded, one might miss out. To check, compare apk sizes, dates. If seems like newer version, extract them before trimming and try an adb install -r.
This will gain some /system space and som /data space as well. However, the linked dalviks will be a larger total so will not help prevent link2sd "Achilles heel." More system space enables experimentation, placing something new there that needs to be.

So of course as many do when rooting want to remove unused system apps to free up storage and memory. I just rooted my Nexus 5 for first time after side loading 5.1. So now I would like to uninstall a few things but have some questions. First off the main things I want to take off are...
Google Hindi Input
Google Korean Input
Google Pinyin Input
iWnn IME
That's it for now but that alone frees up around 100mb. So that is precious space for me since I only have 16gb Nexus. I already have titanium back up installed and es file explorer with root access. With all that into consideration my questions are as follows
1.) Will uninstalling those 4 prevent those languages from being able to be translated in chrome? Or does Chrome control that?
2.) Since they are just languages I assume they will have no effect on system functionality other than not being able to type those languages, correct?
3.) Most importantly will removing those effect any future updates when I have to flash a system update? I'm guessing not but just want to make sure.
4.) Lastly are there any other apps others recommend uninstalling that are not vital system apps? I was also thinking about uninstalling the email exchange and email apps. But really worried that would effect the system if other parts of the system rely on those.
I tried searching for a thread on this and found one from over a year ago but did not want reserect one that old. It also didn't answer these specific questions was mostly about what apps others have uninstalled on their phones.

1. You are not uninstalling a language, you are remove the keyboard used to input it
2. Yes, you just will not be able to type with them
3. If you use the silly OTA method, yes, as they changed the script to check the sum of the entire partition rather than individual parts. The recommended update method now is to simply flash system.img, boot.img, cache.img, radio.img and bootloader.img (skip userdata.img unless you want to wipe data), as it wouldn't check the partition.
4. You can remove those if you wish.
Thanks! I am going for it now. It is going to feel good with that extra space.

Keep in mind that the space freed by deleting system files can only be used for other system files. The size of the /system partition doesn't change with the size of the rom..

That extra space has nothing to do with your 16GB storage. The system partition isn't located on storage, but the data is. So best off all is to use all system. You can do it with make some apps (like Google Messenger) system ones.
Though for now, i still didn't figure it out, how to integrate system apps updates.
To save space odex as many apps as you can and move to system. As the post above says the system space is ringfenced and is seperate. I've taken out google launcher, keyboard etc and put nova etc in the system part. That does save space as does odexing apps.

You don't need to odex them. You have just to create folder in /system/app and move .apk there.
How to uninstalling system app?Uninstalling an app that you have installed on your Android device from Google Play is simple — but what if you didn’t install it? What if the app you’re trying to remove is one of thosethat came pre-installed on your device,provided by the manufacturer, your mobile network, or as a part of Android itself?Removing unwanted system apps fromAndroid can be tricky, but it is not impossible.Why You Might Want To Remove These AppsBefore you start deleting apps, however, you should spend a few moments considering just why you want to get them off your phone.
For instance, it might be that they are cluttering up your home screen. If this is the case, then long tapping and dragging to theRemovebox at the top of the screen should get them out of the way.On the other hand, these apps might be considered “bloatware” and take up valuable resources. Pre-installed games might take up space on your phone’s storage, while Internet-connected apps could be eating into your monthly allowance. Such apps might even berecording and/or uploading informationthat you would prefer they didn’t.And then there’s the impact on your battery life.Unfortunately, removing these apps isn’t as easy as it could be. It really depends upon whether your Android device is rooted or not.
