Answer 1

This stack trace means that you've passed an illegal date format in Twitter.updateStatus.

These are the important lines:

04-20 20:49:56.827: ERROR/AndroidRuntime(826): Caused by: java.lang.IllegalArgumentException
04-20 20:49:56.827: ERROR/AndroidRuntime(826):     at java.util.Date.parse(Date.java:436)

If you're not instantiating that object then it could be a bug in the API. Judging by the API docco here: http://www.winterwell.com/software/jtwitter/javadoc/ it looks like you just pass a status message through to Twitter.updateStatus so my guess would be a jtwitter API bug...

Answer 2

Looks like java.util.Date.parse() is being called with an invalid value?

Answer 3

I'd like to help, if I can reproduce the exception. Is it regular or intermittent? Which version of JTwitter are you using? And what's the status message & account that you use to cause this?

Answer 4

Are you connecting to Twitter itself or another Twitter-like service?

There was a bug relating to Marakana's Android JTwitter tutorial- it used a Twitter-like service, which had a different date format.

Anyway: the latest version of JTwitter has fixed things to accept more variations in date formatting. http://www.winterwell.com/software/jtwitter.php
