If you do a lot of work on the main Thread (which is used by default), then you can cause the UI to stutter. To avoid this, you should do that work in a separate Thread. This is especially true when you're doing something with the internet; you don't want your UI to be frozen while you wait for a response.
runOnUiThread is for when you've done some work on a separate Thread, but then need to update the UI. In Android, you are only allowed to update the UI from the UI thread. So to update the UI from a different Thread, we need to use the runOnUiThread method.
Hope that helps!
