Using SDcard as additional ram?? - Hero CDMA General

is there a way that one can use the space on the sd card as ram? just as windows 7 allows the use of a usb thumb drive to have as additional ram?

an app in the market called droidswap. that will do it for ya.
I use the swap partition from recovery but you can use a swap file also

does this make the phone run any faster?

yes sir, but can compcache is better

Using your SDcard will shorten it's life. Compache set to ~32MB to ~64MB would be your best bet.

using your sd card for swap will eat its brains!!!!!

MicroSD filesystem?

Just upgraded to a 16gb microsd and was wondering what filesystem i should format it to. I know the nexus one itself can format it for me but i just thought i should ask you android veterans out there.
Also, is there any app that can benchmark/check status (health) of a microsd? I know you can do it on a computer but im hoping for an android app
It depends on a few things. If you're unlocked and have a custom ROM like Cyan's, then you can do like 1Gb as ext2/3/4 and use app2sd to install apps to that partition (you can do this from within Recovery, just search for app2sd).
For normal data storage, just do the normal fat32. You can put your music, gps maps, etc on fat32.
fat32 it is then.
I'd use app2sd if i could but unfortunately my card is only a class 2, so i think it would be slow. I dont know how to set that up anyways
you might as well test the cards speed anyway, mine is class 4 and it is actually faster than that
the amount of memory the N1 has most things will be cached or running anyway minimising access to the card.

What's the internal memory good for ?

What good is internal memory on Droid X ? How can you access it and what can you put on there ?
It's faster than SD Card memory because it's built into the phone and doesn't have to pass data as far. You have 8 gigs of it built into the Droid X. I bet you could access it with the Android SDK methods, but I'm not sure if you can put it into mass storage mode like your SD Card.
TL;DR Internal memory faster than SD Card
The internal memory is the default location that all your apps are installed to if you do not choose to use app2sd to run them off of your sd card.

are you sure ? haven't people been complaining of low memory space for apps, like only a few hundred MB.
I have tons of apps and don't use apps2sd for any of them (it gives me nothing but problems). Haven't had a single problem with not enough space.

there's RAM and there's internal memory. RAM is where the ACTIVE apps run, not where they are stored. There is only a few hundred megs of RAM, but thats fine. Internal task killer will start killing them if you managed to drop it below a certain level from running too many apps at once i.e. autokiller settings <> ATK.
What i wish is that apps with libraries could store the library in the internal rather than in the SDcard, it would help with clutter on the SDcard, and probably access faster too...

[Q] Camera won't work, can I get more storage space?

Well, first of all, I'm using the iso installer, and almost everything seems to be working fine except the camera. It just gives a general crash message when I try to use it, or any app that uses it. I think this may have to do with me using a 512 MB storage card (yeah, I know, it's small, but I can't find my other ones). This brings me to my next question:
Since I'm not able to use the "My Storage" on my Omnia, if I use a 16gb SD card, will I be able to use the full storage space?
you cannot use my storage until you are a good in linux - nobody on this forum could not tell me hot to use my storage as fake sd card... but you will be able to use phisical sd card in android without any problem, one thin you can to is installing sd incrase program from market

DarkTremor question

I have 2 questions I am fairly new to the a500 although I have had an evo 4g for years and I have been flashing roms for many more.
I know thebquestion has been asked is there a way to move apps to the sd card. I am wondering if darktremors app2sdgui might work for our tablets and if so how to ise it. I have been seeing threads where people are using 64gb sdxc cards but whats the point if you cant move apps. Im starting to think thosbtablet sucks half the games dont work and you cant freely moves apps.
Anyway my other question is if there is no way to use app2sdgui is there any roms available that allow you to move apps and still have all the tablets good features? I have searched and from what I can tell most roms dont really say they can do it.
Thanks from the bomb

Wrong forum. This should be in the questions section.

I don't have a full understanding of all this myself, but I *believe/think* that the A500 is already moving apps to the SD card -- the internal SD card. The 8, 16, or 32gb of memory that came with whatever model of A500 you purchased is considered the internal SD card, whereas the micro sd card slot is considered the external SD card. Your tablet has 1gb of RAM, which in phone terms is thought of as internal or system memory, like your (and my) EVO 4G has 512mb of RAM. Since the EVO doesn't have any internal SD card, in order to run the newer, larger footprint ROMs we have to use an apps2sd type utility to move as much as we can to the external micro SD card in the EVO 4G.
If you're running out of internal memory in your A500, you can move some data that seems to default there. This happens a lot with apps that aren't really designed for tablets because these apps think that your internal storage is your external micro SD card. I moved all my photos, music, and eBooks from internal storage (where they defaulted) to my external micro SD card. Now I'm only using around 4gb out of the total 16gb that came with my model of A500, and I have tons of apps, games, etc installed. Moving the data barely put a dent in my 32gb external micro SD card, which I mostly use for 720p movies/videos.
Anyone please feel free to correct me about Honeycomb tablet memory handling above!
It's a limitation of Honeycomb not the tablet. Hopefully ICS when it's released soon will solve this problem. I don't know why google designed the tablet specific OS Honeycomb like this it was stupid. There are several work around programs like GL to SD that work so so. I had GL to SD installed and it severely slowed down my tablet so I got rid of it. My first A500 I bought was the 8gb version which I returned a week later after buying the 32gb unit. The 8gb just didn't cut it without being able to take advantage of the sd card for game data.

No its not like this. The phones do have internal memory also. The ram has nothing to do with internal memory, even tho some advertise the ram and internal memory as greaterstorage

Thread belongs in q&a section not dev sorry all
Ok sorry but my testing with the gl to sd app...
the order of chaos game i used that app to move it.. The game took forever to load and ping times went so High you could not play the game..
I Have a pny class 10 16 gb sd card.. tested to get about 8.7 mb transfur rate. and that is about average on most so called 10 mb (class10 cards)
my tablet runs very smooth with no apps running in background.
so i DO NOT RECOMEND THESE APPS.. Just my openion dont bash me if yours is diffrent.. i also dont understand how people are filling up the 16 gb tablet.. that alone has to be slowing your tab down...

You're confusing RAM and FLASH storage. Many older Android devices have a very small area reserved for applications and ROMs, it has nothing to do with RAM. RAM is memory where applications are loaded when you wish to execute them and gets erased every time you power off the device, flash storage is where the applications are stored and loaded from.

I've got the 32GB version + 16GB microSDHC and it's already filled to the brim. I just happen to consume lots of media, including comics, movies, music and books.
Also, the tablet doesn't specifically slow down by the amount of files on it, the process of indexing everything can temporarily slow it down but after indexing is done it doesn't consume resources anymore. Using some sort of an application that just loads everything to memory and doesn't care about trying to watch how it uses the memory is has reserved however can and will slow the tablet down, but that's an application issue, not a filesystem or OS issue per se.
So if the internal memory is like is primary I can't see why it wouldnt be easy to make the external micro sd and ext of the internal. Is that possable?

I found this post online for switching internal to external in honeycomb. I'm getting a 64gb sdxc for my 16gb a500 so it should come in handy.
I have had a mod to voold.fstab under previous Android versions so the OS looked at the physical MicroSD as the external card, not the internal 8 gigs in the Adam. Handy because some programs always wants to look for files on the external card. It was quite easy to do the same thing to Honeycomb, and in case anybody else needs it, here's the full code for the file (which is under \ETC, you need Root Explorer or simalar to edit/replace it):
Code:
## Vold 2.0 NVIDIA Harmony fstab
####################### ## Regular device mount ## ## Format: dev_mount <label> <mount_point> <part> <sysfs_path1...> ## label - Label for the volume ## mount_point - Where the volume will be mounted ## part - Partition # (1 based), or 'auto' for first usable par tition. ## <sysfs_path> - List of sysfs paths to source devices ######################
dev_mount microsd /mnt/sdcard auto /devices/platform/tegra-sdhci.2/mmc_ host/mmc1 # todo: the secondary sdcard seems to confuse vold badly dev_mount sdreader /mnt/external_sd auto /devices/platform/tegra-sdhci. 3/mmc_host/mmc2 dev_mount usbdisk1 /mnt/usb_storage auto /devices/platform/tegra-ehci
So the actual changes are in the fourth and third lines from the bottom, changing around a few numbers. You'll see the difference if you open the original. I have saved a copy of it on the SD card, so if (or rather when) the next update comes I can simply copy it to the \ETC directory with Root Explorer and do a reboot, and it's back where I want it.

Yep, makes sense now that you both mentioned it. Sorry about that. So, it would seem to me that HC actually isn't using any A2SD solution, it's just that tablets typically have significantly greater internal storage and Google didn't expect anyone to really need it. If that's the case then it at least makes a little sense to me that HC doesn't have that built-in and than not many devs seem to be working on this type of project, especially for an A500 which can so easily use external USB storage for the usual storage hogs like media files.
i cannot see why people are so hellbent on apps2sd. seriously, i cannot. well, okay. i admit that it /does/ free up space on your internal apps partition.... but i can't see the point of wasting space on your external SD card.
the apps partition on the iconia tab is roughly 1GB. that's not too bad, unless you've got HD games and crap. i remember Sonic CD and Gameloft's NOVA 2 download stuff to the internal storage; which doesn't clutter up your app partition (the game is like 5mb for sonic cd and like 20mb for nova 2 on the apps partition, the rest is loaded from internal SD).
also, the tablet doesn't suck, if you're having issues with games, they aren't optimised for the advanced hardware that is used in the Iconia Tab. this is tablet hardware, not a smartphone logic board with a few addons and a sexy HD screen. the app developer hasn't taken the time to develop for tablets, most likely.
i guess less is more for me, but w/e.
How does apps2sd actually work? I haven't paid any attention to what filesystem format the internal SD is, but wouldn't just symlinking files work? Or does the Android kernel support loopback filesystems? I'm just wondering, perhaps I'll dig some details myself just for the sake of curiosity and see if I can come up with a solution.
Apps2SD works by moving programs residing in /data/app to the SD card. This can be accomplished in two ways:
1. Classic Apps2SD - This form is mainly used for Android units prior to Froyo, but can be used on Froyo and Gingerbread (and I presume Honeycomb and ICS, but I have never tested it with those Android platforms). By using a Linux partition that is formatted on your external SD card, the /data/app directory is symlinked to that partition. This tricks Android into thinking it is still storing applications in your Internal memory when, in reality, the programs are being stored on your SD card. The upside to this format is that any program can be moved over (and it is done automatically). The down side is that you will need to create two partitions on your SD card (one Linux partition for Apps2SD and one FAT32 partition for SD card storage) and your kernel must be able to run scripts on boot.
2. Secure Apps2SD - Starting with Froyo, Google implemented their version of Apps2SD. Their version moves your programs to a secured area of your SD Card and creates binding mounts to the actual programs themselves so that Android can run them off the FAT32 SD Card. The advantage of this is that no special formatting or programming is needed to implement this, as it is part of Android. The downside to this is that, without special programs, not ever application can be moved to the SD card (the program must be recompiled using at least the Froyo SDK...however, this issue is becoming less noticeable as more programs are being compiled using either the Froyo SDK or Gingerbread SDK).
The Acer Iconia A500 uses neither of these methods. The tablet is equipped with 8, 16 or 32GB of internal storage. Your applications are still stored on the /data partition, but your SD Card is nothing more than a FUSE mount to /data/media, which means both data and apps have access to the full 8, 16 or 32GB of internal storage, so there's no compelling reason that I can think of that you would need Apps2SD on this tablet. If you want your tablet to treat the external SD card as the actual SD card rather than internal storage, you would be better off changing the symlink to /sdcard from /mnt/sdcard to /mnt/external_sd (note that, when you do that, you won't be able to move files from your computer to the tablet by simply mounting the SD card, as the FUSE mount is not pointed to the external SD card, but to internal memory...you will either need a creative solution to change the FUSE mount to /mnt/external_sd on boot or you'll need to use ADB).

[Q] RAM Memory Help !!!

Guys! i might wanna ask something about RAM/Memory because it always gets higher, i mean sometime 167 default up-to 220.
is this normal?
and also i don't know what their been talking about SWAP PARTITION. what is that ?
i'm hopeless, NOOB!!!
Link to swap partition - http://forum.xda-developers.com/showthread.php?t=1659231. Swap is a way to use your sd card's space as ram. Instructions in that thread only.
About your ram, end all active applications frequently and delete system apps which you don't use often. In addition to this, if you use an external launcher, make sure it takes less space on your phone.

its normal.. try uninstalling some useless apps that is running on background...
DONT use SWAP it reallly degrades ur sdcard...

You can use swap with sd cards class 6 or 10, but not everytime.
I am using swap partition for 4 months, and my sd card is not degraded.
