"Skipped 60 frames! The application may be doing too much work on its main thread"--BlogReader

This error just showed up while doing a run I did at the end of the Getting Data from a JSON Request video. I can't make heads or tails out of the info I see when googling the question.

I do see there is a "known issue", but don't know if that could generate this error.

Any insight into this error message and how to address would be greatly appreciated.

In Android you have UI Threads, which are threads that are executed when a UI event happens (a button clicked). These UI events need to happen quickly and if you have a lot of code in your UI events then you will see this error message. Also this will occur with asynchronous events like fetching data from a URL. The solution is to use threads or async tasks. You want to off load any heavy code off of your UI Threads and onto another area - a new thread or in your main activity. This information helped me greatly. Take a look at the section "Worker Threads and AsyncTask":

This definitely helped clear the fog. I am wondering if I did something wrong while doing the lesson, or if the code as per the video does generate this problem.
