[Q] How to get widgets to run from SD card

i got my last question solved but I read somewhere that usin darktremors script would allow me to run widgets from sd card because the system thinks they are still in the correct place.
running GV1.5 partitions fat32/ext3/linux-swap.
I installed the script after mounting /data and /system from the recovery. After that I rebooted and ran the script commands. Moved a widget to sd card and it vanished from screen just like froyo.
what am I doing wrong?
I know you need to move the dalvik-cache for this to work. but recovery can't find sd-ext.

Huh? From what i know widgets will not work if u put them in the micro sd.

Using stock froyo a2sd (apps2fat) will not allow you to run widgets. If you partition your sdcard (ext partition) and use the old style a2sd (apps2ext) using darktremors a2sd package you can run widgets from the sdcard. Along with putting the entire app, not just 1/2 or 1/4 of it, on the sdcard plus all of it's data (optional).
If it's easy for you to understand it as the phone thinking the ext partition is part of the internal memory, that's good enough since it's basically what's going on.

What you did wrong is moving the app to the sdcard. The commands you run in terminal move the apps to the sd ext partition. Specifically this one:
Code:
#su
#cd /system/bin
#a2sd cachesd
It will still show it as installed to the internal memory because it thinks it is. Even in a file explorer under data/app it shows the apps but that's part of the *trick*.
If you go into applications and move it to the sdcard it puts it on the fat32 partition which is where the froyo version puts them - don't do that. That's what you did wrong.

KCRic... huh i didnt know that. Ill try that. Spastic u should try that lol

i installed the busybox 1.18.0.git
wiped everything in recovery and from recovery ran the script. After I rebooted I ran the commands in terminal.
then my phone rebooted...does that mean it worked?

Yeah. You can use titanium backup to make sure. Just open it and you should see a bar at the bottom showing sdext available/free. Also you can use a file explorer - got to /sdext and you should see an app, app-private, dalvikcache, data, and one or two other folders listed. If you do then it worked.
You can also use terminal to have a2sd check and make sure it's working but I don't want to load the thread with commands I'll post them if you want to learn a bit though

Sorry to resurrect this thread, I thought it better than making my own.
I'm running CM 6.1.3 and have an 8GB SD card inside.
1) How do I check how the SD card is formatted? And if it doesn't have an EXT3 partition, how do I partition it property?
and 2) Is there an easy, non-terminal way to send apps to the EXT3 partition, akin to hitting "move to SD card" in android settings. And since, as you said, it moves all the data to the EXT3 partition, not just some, is it best to keep most of my apps there, to free up internal memory as best as possible?
And PS, when I'm partitioning my SD card, will I need to create a SWAP partition? 1GB for an 8GB stick?
Thanks so much.
EDIT: I'm on an X10 if that helps..

Apps2sd

my ROM is a apps2sd ROM. Ext sd is reporting use, i.e. I set 1g of ext and storage says 658mb of ext is free. But in applications my apps give me the choice to Move to SD! ?
I used TB pro to batch move apps to SD but altho my apps now report they are on SD. Ext usage actually went down after the move. Am I confusing Apps on Sd / ext ? So on roms with default apps2sd you ignore in applications that they appear to be on internal mem?

Yes ignore it. You've just moved your apps from ext to fat. Read the root memory faq in my signature

I've some A2SD questions as well. I'm on CM7 with several apps already installed. My 4GB SD card has already been partitioned to 3GB FAT32 and 1GB ext4.
I was getting low memory warnings so I applied the darktremors script (stable, not nightly) expecting it to automatically move my apps to the sd card like your a2sd guide said it would. However, I still got low memory warning, so I manually moved the app to sd card using manage applications. This however moved the apps to the FAT32 partition, and several of my apps suh as my clock widget and swype no longer work.
How to I get my existing apps to move to the SD card's ext4 partition?

They need to all be moved to phone.
The apps should automatically move to ext download quick system info to check a2sd is working.
If its not try "a2sd reinstall" from terminal emulator.
Dalvik-cache is not moved by default and takes up a whole load of space so don't forget "a2sd cachesd" too
Sent from my HTC Desire using XDA App

OK, I thought the a2sd would move existing apps as well, didn't know I needed to "a2sd reinstall". Can I do the reinstall through an adb shell or do I need to download a terminal emulator?
I don't have a Class 4 card, it's a generic card and I don't know what class it is, so should I move the dalvik-cache to the cache partition using "a2sd cachepart" rather than "a2sd cachesd"?
Do I need to wipe cache and dalvik-cache before running any a2sd commands such as reinstall and cachesd/cachepart?
Lastly, do I need to reboot the phone after running these commands?
Thanks.

Ive never seen any performance issues even on class 2 cards. Keeping dalvik on NAND may give a miniscule performance increase, but I think its so negligible, you wont notice. But put it where you want. I recommend card though as you need the cache partition for downloads and as it fills with dalvik, it will limit the size of apps you can download from the market.
a2sd reinstall is for if it doesn't work properly. Its always the first thing to try. Then move dalvik. The way dalvik move works is that it wipes dalvik, moves the location then reboots the phone (rebuilding dalvik so expect delays when booting up the first time). For this reason its best to use "terminal emulator" from the market.
Hope this helps.

Alright, thanks! Will try reinstall and moving dalvik cache to the sdcard. Might get a new faster card since 4GB is getting tight anyway.

Tried the reinstall and it seemed to work. I had to move my apps back to the internal memory in 2 batches since I was running out of internal memory. So here's what I did
1. Move batch 1 of apps from sdcard back to internal memory
2. Run a2sd check in adb shell
3. Run a2sd reinstall in adb shell
4. After phone rebooted, checked my storage to find about 50MB of internal space left (woohoo!)
5. Move batch 2 of apps from sdcard back to internal memory
6. checked my storage to find still about 50MB of internal space left. I guess this means a2sd automatically moved them to the sd-ext partition?
When I ran a2sd check in step 2, the output showed that my ext partition type was ext2 rather than ext4 which I formatted the sd-ext partition to. Is this a mistake?
Will try moving dalvik-cache perhaps this weekend.
Are there any benchmarks I can run on the sdcard to make sure it's fast enough for dalvik-cache? Perhaps HDTach/CrystalDiskBench/ATTO/AS-SSD Bench/etc? There aren't any markings on the sdcard that indicates its class. It's a generic HP 4GB sdcard. Will a "dd if=largefile of=/dev/null" for read and a "dd if=largefile1 of=largefile2" for write work?

I've never known a card too slow for dalvik. Just move it. You can move it back again
Sent from my HTC Desire using XDA App

I believe the ext2 is due to some error with a2sd check. I encountered it too when i used the command and i was using an ext4 partition.
As for dalvik, try moving it. If it too slow then move it back.

Sorry, yes its a bug, fixed apparently in the latest BETA.

Don't think I'll be playing with the phone for a while - it's my wife's phone, and it took almost a week for me to figure things out and start from stock to CM7 with A2SD...now it's relatively stable with quite a bit of internal memory available, so I think I'll keep it that way for a while.
Thanks for all the help!

Hello rootsu,
i installed a Data++ rom and now some applications that i install, not from market, disappear after a reboot. From the market it is fine but if i put a .apk in the card and install it, disappear after reboot. Not all of them. Only some of them.
I have a aura sygic gps and this is one of them that disappear after install. The only way that doesn't is to move to the card. And another one, that doesn´te have the option to move to the card, disappear after reboot.
I already wipe dalvik cache, wipe everytnhig, rom install again, etc...
What's the problem? Do you now? I've searched a lot but i cant find anything.

That's a new one on me.
Install, take titanium backup, boot recovery, factory reset, format /data, titanium restore?

Thanks, rootsu.
And when i go to install again, say that this will replace another application.
I already made a backup, when i have stock, and restore it and happens the same.
What to do?
Edit: I do a backup, only the application, with titanium, and when restore it and say error and dont restore the application.

The cache system space is from sdcard memory or memory phone?
Thanks

Although I am not rootSU, I feel free to answer:
I am pretty sure it uses space of SD Card. Using internal memory would be a little strange, especially we are talking about 160 MB here.

Moving Apps 2 SD

I managed to get my phone rooted and installed nlooooo's 2.3 ROM with the help of a bunch of kind users from here. I'm now having trouble moving some apps to the sd card. I mainly want to move facebook, handcent, maps, es file explorer. Tried moving them through the 'Manage Applications' menu but the 'move to sd card' button is greyed out. I have A2SDGUI installed (came with the ROM) but not sure if and how I can use it to move these apps.
Any ideas?

no need to open another thread on another common issue...
going to link you to another guide, should explain a bit more why you shouldnt need to move apps. you should have read it after being pointed to it previously
as long as you've created your sd partition properly, the script should automatically move them. A2SDGUI app should also let you know.
i also recommend to install 'diskusage', it'll let you browse all your partitions so you can see how space is being used. you may find that your apps are already on sd partition

Just had a look at the guide. Do I need to follow the 5 steps underneath "Assuming you are rooted"? I was under the impression that the ROM I installed already includes Apps2SD functionality.
A2SDGUI says "Apps are on SD" when I open it, however, when I went to 'Manage Applications' I managed to move some apps to the SD card manually, meaning that they aren't all on the SD card.
I've installed diskusage and can confirm that the apps I mentioned in my previous post aren't on the SD Card.

to be honest, i don't think you've read all of the guide, otherwise you wouldnt be asking these questions. read the whole thing, underneath where you referred to. then start at the top and read the whole thing a few more times (trust me i did this several times before i understood)...you can repeat this for many internet guides lol
i've read through your other 'insufficient memory' thread, so have assumed that you've created your sd-ext partition properly using 4ext.
if A2SDGUI reports "Apps are on SD" i'm nearly certain it's already working, it means the apps are on the partition (which is why you made it in the first place).
basically, all your used memory (apps, dalvik cache, data) has to be stored somewhere. when you open diskusage, select the sd-ext option to browse it. the app is quite useful for looking at /data (your 'internal memory') and /system too.
the reason why you might not be able to move some apps depends on the rom, these are likely system apps. you can't move these to sd, and you won't free up any internal memory even if you could move them

If you have problems using my rom you should ask me for help.
Rom has Darktremor a2sd script included and A2SDGUI app should work. However, sometimes it can happen that after a fresh install A2SDGUI doesn't so you have to do the following:
-install Terminal app
-type su (and grant superuser rights)
-type a2sd reinstall and let it finish and reboot your phone. Reboot can last a little bit longer.
After that try to use A2SDGUI, and move apps and dalvik to sd-ext.
Read this thread, there you have all explanations about how to use a2sd.

There's a big difference between apps you moved manually from app management and apps you moved with a2sd. The first one are moved to fat32 partition of your sd card while the second are moved to sd-ext.
You shouldn't do that because you brake symlinks created by a2sd. Go to A2SDGUI and choose move dalvik and rebuild, or execute the same command via terminal.

Sometimes A2SDGUI gets bugged. You can try to uninstall it with Titanium backup (clear data first) and to install it from market, to store it to internal memory, not on system partition.
However terminal is everworking solution...

your internal memory is the /data option.

Does the command 'a2sd reinstall' move apps from the internal memory to the sd card or simply reinstalls a2sd functionality? If the latter, what command should I use to move the apps?
Nevermind, I googled it and discovered it moves both current and future non-system apps to the SD Card.

"Low on space" on rooted phone, ics installed

Sorry to ask the same question again, but I can't find a direct comparison with my issue on here (not that I can recognise anyway, I realise it's probably my lack of knowledge however!)
So, just installed ICS. I chose to have both apps and cache on sd when installing. I have only installed a few apps and already I'm "low on space". I noticed the space drop significantly when I restored my sms messages so maybe that's the problem, but don't understand why the messages aren't being stored on the sdcard as requested. I have previously set up an ext partition (ext3 I think, but I'm not sure how to check).
I'm hoping this is just a setting I'm missing as it seems insane to be out of space so quickly.

Which ROM are u using? You probably didn't activate a2sd script. Run the terminal and type:
1. su
2. a2sd install
3. (Y)es to moving Dalvik cache to sd-ext
4. (N)o to moving app-data to sd-ext
5. (Y) to reboot
And also I suggest you to create ext4 partiton instead of ext3.

Delete your sms again and download quick system info pro and note down ext free space from the first screen. Install another app from play store and check your free space again - if it goes down your a2sd works.
If that is working ok you might just have to limit the number of sms you keep. What HBoot are you on? Maybe that's why you don't have much space for messages.

I've checked that in TE, I'm assuming that a2sd works:

What's bugging me is that when I'm going to Manage Applications I've screen where on start I see how many free memory I have:
Code:

...and after few second free space is larger than @ start:
Code:
i46.tinypic.com/x5avy9.png
Is this normal behaviour? Phone is taking the first calculation (when opening Manage Applications) as a free space, not that after few seconds. That is confusing me.
Is this indicating that there is something wrong with a2sd?

Using S2E - how to move certain apps to internal storage? Alternatives?

Hi
I have CM7 on my Desire with the S2E app to move applications/data to a 1gb ext4 partition.
This has worked fine for months but there has always been an issue with some some apps (Gmail, Facebook) hanging and giving a FC - which is probably down to the (slow) class 4 SD card I have.
So, is it possible to manually move Gmail/Facebook apps back to the internal memory while keeping S2E installed?
If not, what are my alternatives for moving only select apps/data to the ext4 partition?
If I uninstall the S2E app, what happens to all the apps installed on ext4? Or simply, what is the best way to remove S2E?
Any help/advice is much appreciated!
Thanks.

With S2E its basically all or nothing. I'm using a class4 card as well and have no issues with Facebook or Gmail force closing on me. It really depend on what you move to the SD-EXT. I had S2E move everything except Application Data and Dalvik Cache.
The rule here is, the more system related stuff you move to the sd ext, the more information it needs to pull out from the sd card. If your sd card speed is not up to the task, thats where you get reboots or FC's.

Have you tried fix_permissions from terminal or recovery? That sometimes helps with FC issues.

You might create a folder on the original /data partition, move all app-relevant files and create symlinks on /sd-ext/data - the opposite of what Link2SD is doing...

a2sd / link2sd s2e
hi i am using cm9 on my desire and i am wondering witch script/app is working best for increasing internal memory.
i was using a script a year ago (can't remember the name) but all my apps were freezing for a 2-3 seconds. i now installed link2sd with no issues but i can't understand what;s the diff with others, maybe s2e witch support CM is better? any help suggestion?

S2E and a2sd are mounting single folders from /sd-ext/ on top of the corresponfing /data/ folders, e.g. /sd-ext/app/ on /data/app/, i.e. the files go to the SD card instead of to the internal memory. Its called "bind mount".
Link2SD uses symbolic links instead of mounting folders, i.e. you can select which app/data/dalvik-cache goes to the SD card.
Both (bind mount and symbolic links) are cheap operations, once you open a file (read or write) one additonal step (the redirection) is needed. I don't understand why int2sd should be faster (something like "writes directly to the card"!?)...
One reason for read performance issues might be the missing "noatime,nodiratime" mount options - without them, each read operation on files and directions results in a write operation for updating the access time.

S2E is the easiest to install and use. You don't need to flash a separate script just install the app from the market and it is ready to go. If you have a working solution for a2sd already however I would leave it as is unless you are having problems.
