问题
I want to log the stack trace of exceptions into a file. Is there a way that I can get the stack trace in form of a String, or somehow make ex.printStackTrace() print the trace into a stream or a file? I know that there is a way to do this in Java standard edition, but I want this in Blackberry.
回答1:
BlackBerry only provides stack traces when you catch a Throwable. So you should be able to use printStackTrace and friends if you change the catch type.
EDIT Sorry, I misread your question -- thanks for the comment. No, there's no way to get the stack trace in a String object. There is a support forum thread from January 2010 that covers this - Stack Trace Capture (sorely needed). Nothing has changed since then.
If you need this for development, you can extract the event log from the device, which includes stack traces. But that doesn't help sort out production issues.
