[MOD]Cache2SD

despotovski01 · Jul 14, 2011

Hey developers!
We all know that our device has little memory. The Cache partition is only 64MB, of which only 20 are free!

Because of that, I'm going to show you how to use a folder on your SD card to download games and apps from the Android Market, instead of the default one(/cache/download)!

Requirements:
-Terminal Emulator (or ADB Shell)
-Root access

Tutorial:
1. Open Terminal Emulator
2. Type these commands in order:

Code:

su
mkdir /sdcard/cache-download
rm -rf /cache/download
ln -s /sdcard/cache-download /cache/download

3. Enjoy your Cache2SD!

This was tested and it works on SwiftDroid 2.0 RC1

Does this tweak speed up the phone in anyway?

No, but it allows you to download big games from the Market, like Pocket Legends, Drift Mania, etc.

Thanks for sharing!!!

just one question: I can't do this. When i write the third line:

cp -a /cache/download /sdcard/cache-download

terminal says: cp: can't preserve ownership of '/sdcard/cache-download/' : Operation not permited

Can you help me??

You don't have Root permission. Root your phone using SuperOneClick, for example.

I've found a fix: just don't run the line that causes problem and you should be good.

Try this worked for me

mkdir /mnt/sdcard/cache-download
cd /sdcard/cache-download
mkdir download
rm -rf /cache/download
ln -s /mnt/sdcard/cache-download/download /cache/download

You have error because fat32 doesn't support extended attributes (file owner and group). Better solution is to create ext4/2/3 partition on sd card and set it mount point to cache or link it.

Thanks for your suggestion! I'll keep that in mind, but my method works good too.

If cache is just a partition we should be able to repartition internal memory and add 64mb to other one.
