Good tutorial.

It would be very helpful if you could add the steps for using OAuth as it is clearly a better practice. I know this is for beginners (which I am), but the transition to using the OAuth has some more advanced features that lead to confusion.

Of course, not to look a gift horse in the mouth, I do appreciate the tutorial you've provided. If a more advanced continuation of it could be made, that would be really appreciated.

Well I figured out it was not the code at all by the jtwitter library throwing an exception. I switched to the twitter4j library and I had no problems.

It's supposed to crash until you fix the permissions issue. Read the portion of the article about debugging and permissions first.

If you're still getting errors after setting the permissions, make sure you've set the username and password in the code to a real Twitter login. If that doesn't do it, check the traceback from the emulator — run the app in Debug mode in Eclipse, and when it crashes it should prompt you to enter the debugger, where you can step through and find your error. Chances are the LogCat window output after a few steps should give you a fairly descriptive traceback to find your error.

When I am clicking the tweet button in the application the emulator states a force close error. Any ideas what is causing that?

Thanks for taking the time to help educate! Each tutorial I read (yours and others) helps in unfolding the Android dev. process which for this 'old' programmer is a fun new journey. Appreciated.

It is a “good catch” I expected some one of the many eyeballs of the Internet to catch before I did. Perhaps there aren't enough people using your tutorial? I put in a good word for it in Android Beginners, let's see if that attracts any more eyeballs.

I actually meant Resume, which steps deeper into the execution stack (not over) — I was referring to the function of the button and not its label. But since the label is actually Resume I've updated the post to be a little clearer about that.

Good catch; there actually was a typo in Part 4 (it was correct in the code recap at the bottom and in the completed-code download, but not in the entry follow-along snippet). The onClick should have read:
public void onClick(View v) {
String twitterStatus = tweetEditText.getText().toString();
Toast.makeText(TwitterPoster.this,
twitterStatus,
Toast.LENGTH_LONG).show();
}
})

That way the twitterStatus variable refers to the contents of the EditText at the onClick event, not just a fixed string.
