[Q] Offline Google Music when changing ROMs?

When I flash a new ROM and tell Google Music to download some music for offline, is it overwriting the old music I had told the previous ROM to download for offline? Does that make sense? I just don't want 10 copies of each song because I update ROMs fairly frequently.
Thanks.

That's a good question.. I guess the only way to know would be to download some, find the directory they are saved in, then switch ROMs and check the directory for duplicates.

I would imagine google music keeps a record of what it has downloaded and doesn't scan the directory. When you change ROMs this list gets wiped too and thus it redownloads the songs. Of course I could be wrong but I would imagine backing up google music data with TiBu and restoring it might fix the issue?

Each time when you flash a rom or remove the google account from the music app, the system automatically erases everything(music, album art, etc) back to the stone age. So each time when you flash, you gotta download everything again. It's a PITA for me because I have about 10gb of music in my playlist.

Yeah, I'm currently redownloading my 15GB of music with google music. I might just find the directory with all the files and move it, then use a different player or something. I can't deal with redownloading this every time I flash a new CM10 nightly.

/android/com.music or something similar.

[Q] Can't access my old files after switching ROM from AOKP to CM

Initially I thought this was a problem with Google Play / Apollo, but I realize now that when I plug in my phone via USB, I can't see any of the many, many folders and files present on /sdcard that I could see previously.
If I copy a "new" mp3 onto my Galaxy Nexus, it's recognized just fine by both Google Play and Apollo. However, none of my old mp3s (or files, for that matter) are recognized. They were placed in /sdcard/Music, a folder that I cannot see when I plug in my phone, only from the file manager running on the phone. The issue persists if I move an "old" mp3 from my music folder out into the sdcard root, it's still not recognized. This makes me think this might be permission related, but the file manager says that all files are readable and writable.
I've tried running "fix permissions" in both ROM manager and the CWM recovery, but it makes no difference. Any idea what has happened, and how to fix it so that I can use all my old files again?
edit If it's any help, I just ran ls -al in a terminal emulator and I can't see any difference at all between folders I can and cannot see. Example: I can see /sdcard/media just fine, because I created that folder from Explorer in Windows. Music in that directory works. I cannot see /sdcard/music. Here's the permissions:
Code:
drwxrwxr-x root sdcard_rw 2012-09-18 media
drwxrwxr-x root sdcard_rw 2012-09-16 music
This is a bit confusing.
When I try pulling and pushing a file with adb like so:
Code:
adb pull file.tar
adb push file.tar file2.tar
I get
Code:
failed to copy 'file.tar' to 'file2.tar': Read-only file system
I've tried remounting /sdcard in root terminals both on the phone and via adb, but I get mount: Operation not permitted. I'm thinking this might be because /sdcard isn't the actual path but I've tried /storage/sdcard0 and /mnt/sdcard as well and I get the same error.
Thanks in advance for any suggestions.
(This question was also posted on android.stackexchange)

adb push /sdcard/file2.tar
also, cm doesnt have root access enabled by default for adb.
/sdcard/ is already rw, otherwise apps couldnt place anything there. nor could we.

Didn't realize I needed an absolute path, thanks! I now managed to push the file, but it does not show up under the "Galaxy Nexus" unit in My Computer. It does show up when I do an ls in adb shell though. Any ideas?

try disabling mtp on the device; or rebooting, if you want to stick with mtp. maybe it has to refresh file list?

Switching from MTP to PTP does nothing, the same files are shown ("new" files). I'd like to stress that if I take a picture for example, that pictures does show up both with MTP and PTP. New files work fine. It's the old files that I can see in the file explorer in the actual phone that just refuse to show up when I connect to my computer, and they are obviously also not recognized by apps in the phone (such as Apollo or Google Play).
I realize that I could work around this issue by just removing everything from my sd card and then putting it back, but I really want to figure out how this can even happen.

I'm no expert by far, but it sounds like when you changed ROM the"index"file for mtp isn't updates. Have you tried to run the media scanner?

If I've understood correctly, power cycling the device should trigger the media scanner. I just tried restarting, and it made no difference. (I've restarted the device several times since this problem occurred).
Opening the Gallery app still only shows me two pictures (I've taken two photos since the ROM flash), interestingly the thumbs are for other pictures lying around and after a while Gallery crashes. I use QuickPic more often though and that app behaves well, and shows all photos.
edit As a final resort, I tried doing a full wipe and reinstalling CM10 M1 completely, without restoring any settings or apps from any old installations. The issue still persists! Any files created with my now "old" CM10 installation no longer appear, even when they are moved within a folder where other "new" files are shown and working. This is starting to annoy me, but since this obviously is a bug in CM10 M1 I see no point in trying to spend time solving it, I'm just going to switch back to AOKP. Thank you for any answers and attempts at solving this.
edit2 Formatting /sdcard in CWM recovery fixed this, even though it might not be the most elegant solution.

Have you seen this?http://forum.xda-developers.com/showthread.php?p=30288268
Basically what it suggests is that you go to apps via settings, find the "Media Storage" app (it's a system app) Clear data/cache, then reboot. This was my problem.

Google Music to external sd?

Cant get google music to save all my songs locally, have tried to create a link to the external sd which shows up with my 24gb free, but it always fails and says "cannot download music at this time, will try again later"
Any suggestions?

Are you downloading to your computer and your phone is connected via USB? If so, download it to a folder on your computer, then drag and drop it into the folder you want it to be in on the phone.

I was hoping to just have my music download from play music. I know i could download it to computer and put it on my phone. But i was hoping to have it all come from google music so i can have my new stuff upload without having to manually ad d it to my phone.

Have you tried Directory Bind?

You may have too many devices on your account. This happened to me and it wouldn't let me save locally. Just had to go into my account and delete a few old devices. Worked fine after that.

Probably should have mentioned that I have googled and tried everything I could think of. I only have two devices authorized, and I have plenty of storage availible. I guess im trying to find somone who has downloaded all their music to their external card. I have roughly 13gb of music and 24gb free space on my card

This worked perfectly for me. Let me know if you have any questions or help getting it working. Basically it uses root explorer to create a symlink. Note that the directions will actually delete you google music cache and offline music. So you'll have to recache/download everything. If you don't want to do that you can always copy the files folder to the sd card, then do the clear data, and then create the symlink. Let me know if you need more precise help.

Thanks. It starts to download music then says cant download right now. Any ideas why? The link is created properly.
This whole time it has been getting stuck on a couple songs, currupted files I would assume. All is well now.
So just for reference if I flssh a new rom and create the link I wont have to redownload it all?

How fast is your card? I am using the Sandisk Ultra UHS-I 64gb and had no problems downloading any music. I am unsure why you are getting the error downloading files. When you go into Music and click on 'choose on device music', do you see the free space for your external SD card? If you do it should have worked properly. I've read in other forums that they recommend that you don't let your screen go to sleep when music is downloading. Maybe that's it? I also had this weird bug where music would kind freak out if I started playing a song and then pressed the home button to do other things while listening to music. Like when I went back into the Music app to fast forward, the album art disappeared and the music scroll bar froze. What I ended up doing is rebooting the phone. And that resolved my issue. Maybe a reboot will help you with the downloading problem?
And you are correct, if you flash a new rom, and make the link before you open google music, you shouldn't have to redownload. At least this is my understanding of it. I have yet to try. As soon as Cleanrom w/ Multiwindow comes out, I am going to try it, so i will let you know then. If that doesn't work I have a theory that I will try. Basically, making a link of the entire com.google.android.music folder in the data/data directory. Maybe that will be better cuz there are other files besides the files folder that is created. It's just that the music files are stored there. but it looks like other important files are in there like the database files and others. I have a feeling that I'm gonna need to do this to prevent having to download each time I flash a new rom. I will keep you posted.

Yeah. I have a uhs-1 card. It just hangs on a few songs. The same skmgs that whem I try to stream say they csnt be streamed. So I have been deleting them when this happens. I am almost done downloading my 13gb of music, lol.
Please do let us know how the new rom goes.
Edit: May have did it wrong but I updated from CR 2.1 to 3.0 frsh install made the link, but google showed no songs on device. Maybe I will open play music and then make the link after it loads. Next update and see how it goes.

As it turns out, I was right. You need to symlink the entire com.google.android.music fold for it to survive rom flashes. Just symlinking the files folder does save the music files to your external sd card but other needed files like database and what not are still on the internal card and therefore flashing a new rom deletes those essential files. So try symlinking the entire com.google.android.music folder. It worked for me and if you flash a new rom remember to remake the symlink before opening Google Music.
*EDIT*
It appears symlinking the entire com.google.android.music folder only worked temporarily. After a while I noticed my Play Music app just disspeared from my drawer. I had to delete the symlink and copy the folder back over to my internal storage and reboot to get it to come back. Hmm. I think the only thing you can really do is symlink the files folder only so that way the large music files do get saved to your external storage. And anytime you decide you want to reflash your phone, make sure you backup the com.google.android.music folder before you do so. Then flash your rom. Copy that folder back to your internal storage and recreate the symlink for your files folder. That should do the trick.

Loosing media

Hello i recently swapped from ARHD to pabx's [ROM][Feb 8] Jellybean 4.2.1 for Endeavoru AOSP Build [Kernel 3.1.10] #14 but im getting a strange problem sometimes im loosing all the media from my phone (photo's and music). It is still there when i try to mount it from recovery>mount USB.
Before installing the new ROM i wiped the whole sd card and transferred the media files trough MTP,and had no problems with listening to music from the phone until i restarted,then everything went missing. Any help is appreciated.

bump

Hi mate, try this:
Rescan SD
I tell you to do this first as I use this one.
Its not an app, you should just see "Media Rescanned" then check for your music again
If that doesnt work try this one:
Try this second
If not let me know and I'll help further.

Hello and thank you for answering those apps were the ones i first tried,but sadly it didn't work. Any ideas ?

Are you using any different media apps? Like PowerAMP etc? If so, Remove them for now.
Also, as you said, make sure all files show up in PC.
Restart Phone (MAKE SURE FASTREBOOT or whatever its called) IS NOT!!! selected. Turn Fastreboot off.
Restart the phone.
Re Scan media.
Re-check, let me know what happens
Edit (ROOTED) solution:
Another solution is, if your rooted, go to your Music App (In settings) Clear data/cache, Disable the music app.
Restart phone.
Then re-enable music app.
Voila, music should be visible.
(Same applies for Pictures, just follow the steps but for Gallery).
---------- Post added at 04:48 PM ---------- Previous post was at 04:40 PM ----------
Also simply try holding power for like 10+ seconds. You should see a reboot coming up. This is equal to a battery pull, whereas rebooting from the menu is a simple reboot.

I tried this i even wiped cache. I don't think it is related to the music app itself because even with File explorers like Astro and ES i can't seem to find the media files.
PS: I think the fastboot option is only in sense roms ,im with AOSP and didn't find any option of enable/disable this function.

You may wonder why I have so many resolutions for you, its because I had this issue:
My final idea for you to try, then I'm stumped.
This worked for me, but wanted to hold off as if you have alot of music, it can take a while.
Heres what to do:
Plug device into PC.
Copy Music folder (ALL OF IT, including the actual "Music" folder, to your PC Desktop.
When it has copied to PC, Delete it from the device (yes delete it).
Unplug device
Re-scan SD
Restart device
Plug device back in
Create a new folder named "Music" (CREATE A NEW ONE)
Open the "Music" folder you copied TO your PC.
Copy all the music into your new "Music" folder on device
Re-scan
Restart
Some of these steps may not be necessary (such as re-scanning twice) but DO ALL STEPS.
This resolved my missing music, let me know if it works for you. Goodluck.

Removed all media (music and photos) and added them again (trough Recovery>mount USB) then wiped cache and dalvik cache,rescanned sd and the problem is still there :/ The weird thing is that i get this problem only on Pabx's rom and not on any other. I had this issue on RC 11 then swapped back to ARHD ,now im back to RC14 and the problem is still there.
PS:Btw i reinstalled windows,and when i was seting up adb when i type adb devices i didn't get a list of devices as like there was no devices connected,but when i flashed the boot.img (fastboot flash boot boot.img) the boot.img flashed correctly i got the two OKAY's. Might it be related to this ?

Bah, so your not stock I now find out.
I also feel bad for telling you all these things, when it hasnt helped.
I would re-install ADB/Fastboot, and also add the path to your Fastboot/ADB to your envioronment variables. (Control Panel - Advanced System Settings - Envioronment Varibles)
Make sure you add it to the current list, dont replace anything, it should have a " ; " at the start and end of every variable.
That will make it so you don't have to CD into your fastboot/adb folder in CMD. You can use ADB from anywhere.
Also remove any and all drivers related to Android, just to be on safe side. (They'll be re-downloaded when device is plugged)

Ok it's done i flashed the boot.img, (I don't need to reflash the whole ROM right ?)
Now how should i transfer the music back to the sd card ? Trough MTP or Recovery USB Mount ?
PS:The problem is still there but i think it is because of the big /data partition. For now im going back to arhd. Thank you Wilks3y.

4.3 Gallery RR Temporary Workaround

Ok, so many of you, myself included, have had issues with Android 4.3 rebooting your device when you open the gallery app.
If you are like me, and can only produce this issue with MP4 files, then I have a work around for you.
Here's what you need:
-BS Player
-Aftermarket Gallery app of your choice that allows you to EXCLUDE certain folders. (I use QuickPic)
The setup:
-Remove your MP4 files from your device
-Create a folder on your device, specifically for MP4 files
-Open your Gallery, and in it's settings, exclude this new folder
-Put your MP4 files in this folder
-Done
Now what you have, is a working Gallery app that will not RR your device, because it never accesses the excluded folder, where the trouble files are. And you also have an app to play these files, and will not RR your device.
Obviously, all risks are on you, and I nor anyone else can be held responsible if you mess something up listening to people on the internet.
I also know this is not the solution people are looking for, but it works!

Not as of yet. I have sent several LogCats of this instance, and have had several people look at them. Last update was a few hours ago...It's going to the "expert" ...
The issue is that not everyone has the problem. So...all we can do is wait.

Thanks for posting a workaround. Like you, opening the Gallery is fine and dandy. I believe someone mentioned this in the nightlies thread, but I noticed this issue only occurs with mp4s recorded prior to 10.2. A video I recorded a few days ago on 10.2 plays without any indication of difficulty.

If that's the case, then the encode is different... So maybe the gallery is missing backward compatibility for MP4's?
http://developer.android.com/about/versions/android-4.3.html
"The framework underlying these APIs has been updated to support parsing of fragmented MP4 files, but your app is still responsible for parsing the MPD metadata and passing the individual streams to MediaExtractor."
Maybe that's the issue? I'm only speculating here...

Considering streaming intent of the fragmented MP4 file support, I would guess that there's a separate implementation for it to the extent of which the decoding of non-fragmented files would be retained.
Looking at the last kmsg of a crashing video, I suspect the following log entry is probably the source of my failure. Either my existing videos are corrupt in some way, or perhaps you're on the right track and the file header is being read incorrectly leading to explosions.

fixed gallery crash
I found this in the forums.
Backup your DCIM directory and then delete the DCIM directory. When you use Camera it will recreate the directory. Copy everything back into the DCIM directory and then it shouldn't crash anymore.
This is the only thing that worked for me.

No dice. But thank you

ok all i did was go to gallery.3d in .android and delete the folder and restart and problem went away

I just wanted to let you know that this worked for me too. I just transferred the videos over to my computer and removed them from my device's storage. No problem looking through my gallery now. I did switch to QuickPic. I kind of like it. :good:
Thanks!

No need to transfer files
MP4 files are the culprit but there's no need to transfer files twice. Just create a nomedia file in the directories where you have videos. Create a new folder for your videos. Use Quick Pic to exclude that new folder then transfer your videos into that new folder. You can now delete the nomedia file.

Its a shame most people can't be bothered to search and find threads like this or posts about the issue in the other threads. I guess its easier to just make a post about it and wait hours for an answer. Lol

I don't have any mp4 files but yet the gallery problem persists.
edit: I finally fixed my Gallery issues:
I was in need of consolidating my pics because of all the various ROMs throughout the lifespan of my Hercules so I moved the DCIM/Pictures/anything else with a *.JPG or *.3GP (didn't have any *.MP4s but would've done those as well) folders themselves to my PC so that they were completely deleted from my internal and external memory on the phone.
I then took a picture as to let the phone recreate the DCIM/Camera directories and proceeded to put all of the *.JPGs back in that one folder but NOT the movies. After that everything was finally solved and I've flashed several 4.3 ROMs to test.
So it was basically a combination of deleting any pic/movie folders and also avoiding both MP4s and 3GPs when I moved things back from the PC. At least for me, 3GPs were also a culprit in addition to the MP4 issues which others have mentioned.

my problem was that i had 2 gallery folders and what i had done was went into the android folder in root explorer
storage/sdcard0/android
then i deleted a folder that said gallery.3d or something relevent
then i rebooted phone and worked for about 3 to 4 weeks then i flashed new rom and problem appeared again -_-

I've noticed in the last few weeks worth of nightlies that my MP4s which were recorded prior to when this issue began to work again. Kind of...
When I rotate my phone to match the landscape orientation of a video that would result in a reset, the freeze frame preview now updates accordingly, where as previously it would still use the same sized portrait orientation preview. The video proceeds to play fine. If I attempt to run the same video in portrait mode though, it resets.

Good fix
