@cwnga Looks good overall, nice use of abstractions re TwitterHandler and HomeTimelineResult and it seems you got everything more or less working. Any questions for us about the assignment or any of the things we covered?

I have a question about network loading, I remember network connection can not exec on topper level, it is because blocking activity exec , is it ? how to implement network connect (fetch data...) in background?, and then , i see the facebook app, it can loading text first , loading image later , how to implement this flow?

Anson,

You're right, network loading must not happen in the UI thread. If you're using the lower level networking libraries, then you must use AsyncTask to ensure that the network requests happen in a background thread.

In our past homework, we've been using a library called android-async-http which automatically wraps the network request in an AsyncTask.

Does that answer your question?
