Save offline music to external SD card with Google Music 4.0? - Android Q&A, Help & Troubleshooting

I downloaded the leaked google music app from ICS, and it works great.
My only caveat is that when I choose to make something available offline, it goes straight to my internal storage (Motorola Atrix).
I have a 32gb microSD card with a dedicated folder for music. Is there a way I can get the offline songs onto there?
I currently use PlayerPro from the market, and I wanted to use the Google cloud for "wirelessly syncing" my music.
Any ideas?

Nobody was able to figure it out?

---

Does any other music player sync with google?

Wouldn't it be possible to somehow mount a folder that is located on the sd-card and link it to /sdcard/Android/data/com.android.music/cache just like it is done with the apps2ext hacks on low memory devices?
Would the file system of the sd-card then have to be ext instead of fat32?
Maybe someone who has more practical knowledge of the matter could look into this. I can only theoretically assume how it might work

---

I did some further research and found this post.
It describes how to mount an external sdcard to to /sdcard instead of sdcard. But would this also work with a subfolder of /sdcard?

---

I fiddled around myself a bit.
So here is what I did:
format sdcard as ext2
manually mount sdcard since it won't automatically when ext:
Code:
mkdir /Removable/MicroSD
mount -r -w -t ext2 /dev/block/vold/179\:9 /Removable/MicroSD
mkdir /Removable/MicroSD/GoogleMusicData
Then move all data from /sdcard/Android/data/com.google.android.music/cache to /Removable/MicroSD/GoogleMusicData/cache
I did this with root explorer since I'm not too much of a terminal h4xx0r.
Delete the folder /sdcard/Android/data/com.google.android.music/
Link the new Folder on external MicroSD Card to the original location via this terminal command:
Code:
ln -s /Removable/MicroSD/GoogleMusicData /data/media/Android/data/com.google.android.music
Since /sdcard is already a link like the one we are setting up here, it is not possible to link to this linked location (/sdcard/Android/data/com.google.android.music).
Instead we have to link to the origninal destination of /sdcard which is /data/media.
Now the microSD card is accessible for root explorer. It shows read and write access.
But google music won't find it. It says that it doesn't have enough space to stream music so I figure that it somehow doesn't have access to the sd card.
What could be the issue here?
Also instead of 28GB free memory root explorer shows me only 364,44MB free memory. the command "df" in terminal however confirms 28GB of free memory.
Help please?
EDIT:
I thought that a reboot might do it. But it doesn't. Instead it gets rid of all the hacking I've done in terminal. So I guess I would have to place a script in /etc/init.d for the link to be set everytime I reboot, right?

Another Fix (no sdcard formatting needed)
This is a fix i figured out piecing together other peoples attempts.
Use this as a script
mount -o bind sdcard2/android/data/com.​google.android.music sdcard/android/data/com.​google.android.music
Alternately you can change the first location to the location of your choosing as long as it resides on the external as card.
Ex.
Mount -o bind sdcard2/music sdcard/Android/data/com.​google.Android.music
will bind:
sdcard/Android/data/com.​google.Android.music (google's forced save location)
to
sdcard2/music
Go to google music (play music now) settings and clear any music that is currently saved to your device.
this only applies to music made available offline. If you do not clear it before running the script the music will exist on your internal sdcard but not be accessible.
open script manager and find the script you made
Select it and make sure to click set on boot and superuser
Run Your script.
That is it now your default save location for google music is bound to the location on the external sdcard. the device will see the location as its default but really be saving to the external sdcard.
You can check this by going to google music. Selecting "make available offline" and look at the free space. It should shoe the space available on your external sdcard.
TLR Version (noob version)
I was getting a lot of questions about the preliminary steps here (i.e. rooting, writing script, etc) so i decided to attach the noob version in case anyone needs verification on how to accomplish these steps.
HOW DO I ROOT?
So, Rooting gives you full access and control over your phone. instructions for how to root are device specific. so i would start by searching XDA for "YOUR DEVICE one click root"
ex. samsung galaxy s2 one one click root
some devices are easier to root than others. i cannot provide steps for your particular device, but through XDA, and google you CAN find everything you need.
some devices have one click root tools, some do not, so the rooting process is more in depth for those devices.
rooting instructions are so device specific i could not find a generic set of instructions, and don't want to mislead anyone by linking them to a set of instructions not ​compatible with their device.
There is a risk of bricking your device (making it inoperable) while rooting, although the risk is minimal... almost non existent if you carefully follow instructions. I have rooted 5 seperate devices without bricking any, and, in most cases even if bricked the device can still be restored.
there are additional benefits to rooting, such as overclocking
for example my Galaxy S2 normally runs at 1.5 GHZ, i have increased the speed to 1.8GHZ
(NOTE** Without XDA DEVELOPERS i would have rooted 0 devices, and probably bricked at least one, so thank you to all of you out there who have helped me, I hope this method will help some of you in return.)
NOW THAT YOU ARE ROOTED...
INSTALL SCRIPT MANAGER..
First, to install script manager just go to google market (Play Store) and search for script manager
INSTALL ES FILE EXPLORER..
To make a script go to google market (Play Store) and find ES File Explorer
WRITE SCRIPT..
Open es file explorer when install completes.
in es file explorer click the menu button, and select "new"
when prompted select "File"
name your file something you'll remember
Ex.MusicScript
Click your new file
when prompted select "Text"
type this EXACTLY how you see it
Mount -o bind sdcard2/music sdcard/Android/data/com.​​google.Android.music
press back and when prompted to save click yes
MAKE DESTINATION FOLDER..
now on es file explorer click "Favorites" (the star)
a new menu will pop up, at the top you willsee a picture of a phone with "/" underneath it click the phone
this will take you to the root directory
click the folder Sdcard2
click the menu button, and select "new"
when prompted select "Folder"
Name the folder music
Your script and destination music location are created
EXECUTE SCRIPT..
now open script manager
find your script which should be located in the directory /mnt/sdcard and the file name you chose earlier
select the script
open as script/executable
make sure script is selected not executable
click the buttons for "Su" and "Boot"
click save
Go to google music (play music now) settings and clear any music that is currently saved to your device.
this only applies to music made available offline. If you do not clear it before running the script the music will exist on your internal Sdcard but not be accessible.
now reboot the script will run at boot a prompt will appear asking for superuser rights, click yes and remember this selection (it may say something different than remember this selection whichever option resembles remember needs to be selected.)
YOU'RE DONE!!!
your music should now save to sdcard2/music but the device will still think it is saving to the default sdcard/Android/data/​com.​google.Android.music
You can check this by going to google music. Selecting "make available offline" and look at the free space. It should shoe the space available on your external sdcard.
So try your hardest to figure out how to root using google, and if your not confident enough to attempt it this fix may not be for you.
if you have tried everything you can and are still stuck message me back, including what device you have, and i will see if i can find a link to the rooting instructions for your particular device.
I assume no responsibility if you damage your device... These steps do work, and if followed will fix your music issues as well as introducing you to a world of additional benefits of being a rooted user.

Hey FuzzyMeep Two! Thanks for the great tutorial.
It worked, with some minor adaptions:
1.) The script should read "mount -o ...". Note that there's no space between '-' and 'o'. You got that right in the first script though
2.) On GalaxyS2 with JellyBean/4.1.1 the correct paths are storage/sdcard1 (external) and storage/sdcard0 (internal).
regards,
Patrick
