I barely recommend apps on my blog (or did i) but this is special, there is an application on the market called Log Collector, what it does is it collect the logs from your phone and email it to whom ever you want it to be email to. So how can i make use of this?
As a developer, most of the time you would get a force close when testing your application on a real phone, but most of the time you don't have any idea why it happened. So here is how Log Collector is really useful, after a force close, you immediate email the report log to you or the developer of an application. It might help you a lot or atleast have a clue on what's going on.
Hope this helps :)
