I have the same problem with the Invalid argument error
I think it has something to do with the sdcard writing speed. It says mine is 4mb/sec and the required minimum is 6mb/sec bu Im not sure. Someone with more knowledge should say whats wrong.

NOTE:
This Wont Increase Your Real Ram Because RAM is a Hardware . So It wont show u as 512 MB or 256MB in Task manager.

READ STUFF:

RAM
What is RAM
Random Access Memory (RAM) is temporary data storage that the CPU uses during calculations. The more RAM a device has, the more calculated results the CPU can store - which means less time the CPU has to do the same thing over and over again. In other words, the CPU can check RAM to see if it has already made a particular calculation in the recent past. If it has, it can use the pre-computed results instead of wasting processing time recomputing the same calculation. In short, more RAM means a more efficient (and faster) device.
SWAP

What is SWAP
Swap is, in short, virtual RAM. With swap, a small portion of the hard drive is set aside and used like RAM. The computer will attempt to keep as much information as possible in RAM until the RAM is full. At that point, the computer will begin moving inactive blocks of memory (called pages) to the hard disk, freeing up RAM for active processes. If one of the pages on the hard disk needs to be accessed again, it will be moved back into RAM, and a different inactive page in RAM will be moved onto the hard disk ('swapped'). The trade off is disks and SD cards are considerably slower than physical RAM, so when something needs to be swapped, there is a noticeable performance hit.
Unlike traditional swap, Android's Memory Manager kills inactive processes to free up memory. Android signals to the process, then the process will usually write out a small bit of specific information about its state (for example, Google Maps may write out the map view coordinates; Browser might write the URL of the page being viewed) and then the process exits. When you next access that application, it is restarted: the application is loaded from storage, and retrieves the state information that it saved when it last closed. In some applications, this makes it seem as if the application never closed at all. This is not much different from traditional swap, except that Android apps are specially programed to write out very specific information, making Android's Memory Manager more efficient that swap.

INCREASE RAM USING SWAP FILE .
Many New bees told me the method by Sir CarlDeanCatabay is tougher .

Hi Guys , our Galaxy y is Cursed with a 289MB Ram which is poor for Multitasking and gaming.
Here we are going to see about Creating a swap which will move background running pages to swap file and gives the fore ground running apps a free space to work smoothly.
I have searched the Play Store and found the exact app for this process.
ROEHSOFT RAM Expander (SWAP) APP




Things needed:

1. Root permission
2. A Custom kernel with Swap support. (Check the XDA post of your kernel)
3. No Partition required
4. A Sd card of minimum class 4 ( Tweaked ) [Recommended:For best results , use a higher class Sd card}
5. Before asking doubt's please read the FAQ's section.

Procedure:

1. Install The App (ROEHSOFT RAM Expander (SWAP) )
2. Give Root Permission and Select your language.
3. Use the SWAP FILE Slider and select the amount of partition you want. (may be 100-250 MB)
4. Use SWAPPINESS Slider : By setting the swappiness value, you can control the behavior of the kernel, the higher the value the more is outsourced.(Rec:60)

Final step: Tick AUTO RUN and SWAP ACTIVE and it take some time creatin SWAP file according to size you selected (only for the first time)
That's it....

FAQ's

1.Where wil be the Swap file Created ?
A Swap file will be present in your SD card after creating the Swap. ( Do not Delete it)
2.My SD card Class is low , any solutions ?
*Actually we only tried this app with Class 6 and got good results
*Do me a favour by testing with Class 4 sd card and make a comment here
*soln: Use SD booster app |APK link | Play store link|
3.Whether this method support my kernel ?
*SWAP support is must for this method . Check your kernel thread whether it supports swap or not.
4.Whether my Swap is active or it's fake one ?
Need: Terminal Emulator

1. Go to the terminal emulator
2. type "free" and enter

A] If it looks like this (with zeros in the swap line), you do not have swap:

B] If it looks like this (with anything other than zeros in the swap line), you have swap active:

TroubleShooting:

1. Take a backup of App ( You can use it any time , u want)
2. Uninstall the App
3. Check The Sd card whether the Swap file deleted, if not delete it.
4. A Reboot
5. You are good to go now...

Caution:

1. Dont delete the Swap file before uninstalling the app.

Conclusion

1. Comparing with partion method, this method is quiet easy and Simple.
2. This will help you in Multi tasking.
3. For better Ram management use Tweaks

MUST READ (Senior Members):

U Can try this app but THIS POST IS MAINLY MEANT FOR USERS WHO HAD SUCCESS or TRIED , Sir Carl Dean Cantabay's Method.
So Dont give your bad views on it. CarlDean Catabay's post is a PORTAL thread[popular}
thread link
