Most of the time, we software developers focus on optimizing our code. We want it to be fast, easy to understand, and easy to maintain. Many of those codes are related to data handling, API queries, record updates, etc. But how many times do we worry about optimizing the user interface?

When we navigate to a screen in any application, we usually load a certain amount of information. If the load is slow, the first culprit is the process that retrieves the information that should be displayed on that page, but this is not always the case. Sometimes the slowness is due to the view not being programmed properly and doing something called “overdraw”.

“Overdrawing” occurs when your app draws the same pixel more than once within the same frame. Your app might be doing more rendering work than necessary, which can be a performance problem due to extra GPU effort to render pixels that won’t be visible to the user.

Fortunately, Android has some tools to identify and correct those scenarios.
