debugging problem

[Smee]

I am in the process of debugging / crashing a program.

I am able to crash the program if i do 3 downloads in a row and then go to another activity. I do not know why the program crashes because i am unable to interpret the log properly

it looks like it has something to do with ftpwrapper but i make sure that the ftp is closed when the service is destroyed.
ftp.close

Is this what is causing the error?


update:

I have done further testing and it seems that if i run the ftp service 3 times then the error appears. it does not need to be 3 times in a row.

This is a bug. It is fixed for the next version. Do you also make Http calls at the same time?

Thanks for the quick reply Erel,

I do make http calls in the form of displaying data in tabular form but not at the same time. I haven't got to the stage of extensive debug/crash testing of that yet.

Is this also part of the bug?

It might be related. Anyway it is fixed for the next version which will be released in a few weeks.
