Examine logs from the past with logcat?

问题

I'd like to examine stack traces from the last hours. I haven't found a proper logcat command. Does Android "forget" those logs?

First story:

When I find an unhandled exception in my co-workers Iphone App, he connects the iphone to his computer and reads the stack trace into x-code. X-Code also visualizes the exception in a nice way. Is there a smth. similar in Android?

回答1:

You probably won't be able to see those logs from the past hours. Imagine that your phone stores all logs, how much space will it consume in a couple of days?

So, this is what I do:

• I'm in the autobus, and suddenly the app I'm working on crashes!
• I'd like to see what's the logcat output to analyze it at home
• I just launch the Android log collector app, and send myself an email with the logcat output
• I get home, have dinner, feed the dogs and then I can start working on the logtrace I emailed hours ago.
