Changing where special://masterprofile/ redirects to? - makkonen - 2013-02-27
I just updated to a new ROM on my phone. XBMC had been functioning flawlessly before that, but since the update, it crashes on startup.
http://pastebin.com/sfyGNDM3
The source of the problem is obvious. instead of redirecting to /mnt/sdcard/Android/data/.xbmc/files/userdata, special://masterprofile (and a number of other special protocol links) redirect to //.xbmc/files/userdata. Since the XBMC app has no permission to write to the root directory (nor should it), it fails rather abruptly.
I have grepped through every file in the apk, and do not see any way to manually tweak where special://masterprofile/ points. Nor do I see evidence of where in the Android system it is trying to pull a sensible path from.
On my galaxy note II, the internal storage shows up at /sdcard, /mnt/sdcard, and /storage/sdcard0. The sdcard shows up as /mnt/extSdCard and /storage/extSdCard (and possibly others). These are pretty standard, but clearly something is missing. (a shell variable? I don't know.)
Can I manually set this path? Or does someone know how XBMC derives its path, so I can convince the system to pass it what it needs?

Line 906 in https://github.com/xbmc/xbmc/blob/master/xbmc/android/activity/XBMCApp.cpp looks to be where the trouble lies. It is pulling the external storage location from the Android Environment class.
I was just working with someone about this problem on custom ROMs and have posted a build with extra debugging. Can you try running the build and posting a logcat / xbmc log? It should shed some light on what may be going on.
Build: https://nuskunetworks.box.com/s/2z3900opqvtopzykjgfs
As an aside: which ROM are you running?
RE: Changing where special://masterprofile/ redirects to? - makkonen - 2013-02-28
Just switched from stock to Synergy ROM on my Sprint Galaxy Note 2.
I will install your build and send the log as soon as I am able. Thanks!

...which turned out to be pretty soon. Unfortunately, the log looks pretty much identical. Is there a method to turn on more debugging output that is called early enough in the process to be of use here?

Next step is to figure out if I can hack how this ROM populates the Android Environment class, I guess. That doesn't sound very simple. Thanks again.

I've been seeing quite a number of reports (see this http://forum.xbmc.org/showthread.php?tid=150676), and I've been experiencing this too.
I guess I'll post the logcat or XBMC output in time with the debug build, as rooting is not an option for me.
(Besides special://masterprofile special://home is also pointing to .xbmc at root, I don't know how many other things are missing with an attempted install like this.)

Interesting, the build I posted should have had some lines prefixed by KmN. Time to go poking around for more spots to add information to. Will post back after I do some digging.

Here's what I got when I ran your posted build. log

P.S. If only we have a build that allows users to manually define a path. or part of the path, where special://masterprofile and special://home is mapped to, if would be made MUCH easier
RE: Changing where special://masterprofile/ redirects to? - kemonine96 - 2013-03-04
Thanks for the log. Unfortunately my switch and router flaked out this weekend and I am still in the process of repairing them. Hopefully I'll be back up this week and I can put together an updated build with more logging.

Seems to me that the following file have a lot to do about where special://home and special://masterprofile is mapped to.
https://github.com/xbmc/xbmc/blob/master/xbmc/filesystem/SpecialProtocol.cpp
Is there anything you can tell from this file where we get the special://masterprofile and special://home folders from? Or (I know I'm begging for it) some tweaks that can be done that alters the code...like hardcoding sections here when referencing paths for special://home and special://masterprofile .... I'm almost begging for it!

Real life has tripped me up some. I'll take a closer look at the code you posted soon. Feel free to PM me if I don't have something posted by the end of the week.
RE: Changing where special://masterprofile/ redirects to? - snotboble - 2013-03-11
I have observed the very same thing on my device (AGPTek TP15H, Android 4.0 upgraded to JB).
It maps the flash to /mnt/local and XBMC does not seem to be able to figure that one out. I tried a hack of synlinking the /.xbmc to a more appropriate path (had to remount rootfs rw, then ro again) but this is not persistent across device reboot, so I'm latching onto this thread.
RE: Changing where special://masterprofile/ redirects to? - cyberguerilla - 2013-03-17
Thanks, eagerly awaiting anything you find.

So far I've found nothing. I was poking at this yesterday some and I can't seem to find the spot where it loses the SD Card location.
Anyone willing to post the output of "env" from a command line (on device) on a working and non-working ROM? That might help me find the right spot to go digging.

Sure, here goes:
