For some reason I get an error when I try to display my twitter post in my app. I followed along with the videos and just changed the url from the treehouse blog to my twitter post url. I get some AsyncTask errors when I try to display the charArray in the log. It works with other urls so is my url bad? If so, is there a way to change it so that it does work?

Treehouse TeacherHi Domonique Dixon,
I'm sorry you are having this trouble! It looks like you came across an issue with the Content Length property that was logged in this other forum post. Please read through that post as I posted an alternative version of the doInBackground
that should fix your problem.
I still need to either re-record or somehow address this issue in the context of the project. I'm sorry I have not done it yet as I've been focused on other priorities. Anyhow, hopefully this other solution helps you out!

Treehouse Project ReviewerFirst, to give you the best possible answer, please post your code.
Second, I don't believe you can use a charArray in a log. Convert your charArray to a String. Then try to log it. http://stackoverflow.com/questions/7655127/how-to-convert-a-char-array-back-to-a-string-java
