Application Log Files

[kalnyc1]

Hi,

This may be a silly question, but here goes.

I have searched and found no answer, so, where (directory) can my application place a log file that I can view without having to deal with all the security issues.

Can my application write a log file to the "C:\" directory, and am I able to view it using something like Y-Xplore? The security capability aspect of the OS makes it so frustrating to test and develop on.

Thanks in advance.

C:\Data and E:\ are perfect locations, you can see them from the built-in File Manager too (it shows c:\Data as "Phone Memory" root)

Thanks. I will give it a try.

Doesn't seem to be working. I am only guessing, but perhaps my application cannot write to the C:\Data directory.

I can only guess, because I'm developing blindly here, I cannot see anything, no permissions!!.

It works fine in the emulator, though

Hi,
Try adding capability ReadUserData WriteUserData in your mmp and then check if it is writing in the log file or not.

You need not worry about special signing also since these capabilities are user defined capabilities so you can self sign your application also.

I am using Open Signed Online and I "Select All" capabilities. I tried adding ReadUserData WriteUserData in my mmp, no success.

If you learn about data caging, you will see that any application can write into c:\Data.
And Read/WriteUserData has nothing to do with file access anyway.
You should check how you are trying to open/create the log file. Show some code perhaps.

You got to love this "add capability X and Y" approach. Of course at some point you run out of capabilities (it seems kalnyc1 already did) and then what? Use a bigger hammer?!
