App searches in wrong directory

Question

I just installed DroidID3Tagger, however it just searches for my music files in /mnt/sdcard, my music however is in /mnt/emmc.

Is there anything I can do instead of moving the files?

I'm using CM9 Nightly on a SGS1 with Icy Glitch Kernel. (for some reason the Kernel swapped sdcard and emmc)

Answer 1

In response to @Zuul's comment below his answer, usage of the ln -sf /mnt/emmc /mnt/sdcard is not the appropriate way of dealing with it, because it's a soft-link and forcing it that way, can lead to some mis-behaviour of apps who are relying on the SDCard's mount point, by way of refusing to work with it, Play Store can fail in this regard.

The best solution is to use this:

By using busybox, explicitly bind the mount point to make /mnt/emmc behave exactly like a SDCard, i.e:

/system/xbin/busybox mount -o bind /mnt/emmc /mnt/sdcard

Which will show up as a mount point in the proper way, if this was a soft-link it would end up like this -

/mnt/sdcard -> /mnt/emmc

Google Play store, as I mentioned has an internal checking mechanism to see if the directory is not a link (it will return a error of -22 IIRC).

Answer 2

This app reads files from the device internal storage located at /mnt/sdcard, not from the external storage or any other location.

Since the app was last updated on March 4 2011, I don't think this will get fixed.

However, if you have root on your device, you can create a soft link from one location to another thus tricking the app.

The command is used like this:

ln -sf {target-filename} {symbolic-filename}

So you should execute:

ln -sf /mnt/emmc /mnt/sdcard 

When the app accesses the /mnt/sdcard the system will give it the contents of /mnt/emmc.
