I am generating file names that contain a timestamp in the following format:

"base_name (yyyy-mm-dd hhmmss).ext"

This seems to cause a problem on Android. Here's my log:

/storage/sdcard0/anMoney/transfer/Net worth over time _ Forecast (2012-11-19 110550).pdf

Now, if I trim the file name to have only 16 characters within the parentheses, everything is working as expected. I am able to send the file as a GMail attachment.

The following file name is working fine:

/storage/sdcard0/myapp/transfer/Net worth over time _ Forecast (2012-11-19 11070).pdf

I tried the following troubleshooting:

• It's not the overall length of the file name, as if I shorten the base name, the same behavior remains
• It's not GMail, uploading the file to Google Drive fails similarly
• 16 characters inside the parentheses work, but not 17
• It's not the space character inside the parentheses that causes the issue, as I replaced it with a dash and it's the same problem.

Anybody has any ideas on what's going on here?
