conflicts with GVFS for access to MTP device

[maximumultraist]

When I try to use AFT on a GNOME system, GVFS "steals" the mount and denies AFT access unless I kill gvfsd and all dependent processes. Is there any way to work around this?

[whoozle]

I don't know, maybe filing bug in gnome bugtracker will help. They might mount vfs lazily on first access or something.

[whoozle]

Maybe it could be solved by message box with "stop" buttons ;)

[mariellep]

I think that I might have this same problem as well. My problem is that I can't disable MTP as soon as I plug the phone (Samsung Galaxy S4) in, so when I try to run the program it complains about MTP already running. I've been trying to figure out how to disable MTP on the phone side, but so far no luck. :/

I tried killing gvfs-mtp and then running the program, but got this error message:

vector::_M_range_check: __n (which is 0) >= this->size() (which is 0)

and then a blank window.

[whoozle]

Try run it once again after this error

[mariellep]

No dice. It doesn't seem to be detecting the device at all once gvfsd-mtp stops running, hence the blank window in AFT. If I leave the phone plugged plugged in, then it reconnects and it's in MTP mode once more.

I should also note that I get the same "Device is busy, maybe another process is using it. Close other MTP applications and restart Android File Transfer." message when the phone is in PTP mode.

Ugh. If only my music files didn't have spaces in the names. I'd just use good old AWK+adb to handle everything in terminal.

[whoozle]

If AFS could not find device it shows "device not found" dialog. It looks like your DE/udev keep restarting gvfsd-mtp. You could try uninstall it, if you'd prefer.

But before that, can you help me debugging this range check exception?

[mariellep]

Sure thing. What do you need me to do?

[whoozle]

clone the latest master from git and cd inside

rm -rf build # if you built it before
mkdir build
cd build
cmake .. -DCMAKE_BUILD_TYPE=Debug
make -j
gdb ./qt/android-file-transfer

then type the following commands in gdb console:

b mainwindow.cpp:137
r

then breakpoint triggered, type:

catch throw
c

finally you will get all c++ exception after device detection, like range_check you mentioned.

type bt to get backtrace and send it here.

[mariellep]

Here's the output for the exceptions.

[whoozle]

You might forgot to run program after setting breakpoint in main window or run it more than once.

Please note that you have to run program, then type "catch throw" after first breakpoint triggers. This is needed to skip exception you sent me. :)
But yes, it's almost what I needed, but first exceptions from parsing usb sysfs tree are not relevant. Can you try it again? If you fail for the first time, you might need to disable catch point you set earlier with catch throw or just quit the gdb and start it back. (or you will be getting exceptions from sysfs parsing)

[mariellep]

How about now?
