What is overdraw in android ?

Overdraw refers to the system's drawing a pixel on the screen multiple times in a single frame of rendering. For example, if we have a bunch of stacked UI cards, each card hides a portion of the one below it. However, the system still needs to draw even the hidden portions of the cards in the stack. This is because stacked cards are rendered according to the painter's algorithm: that is, in back-to-front order. This sequence of rendering allows the system to apply proper alpha blending to translucent objects such as shadows.

About Me:

I began my professional journey when I was in my 6th Standard (2009) and have since worked on a number of solo and collaborative projects. I take pride in all that I do and in the long-term relationships I’ve fostered in the process. I firmly believe that hard work eventually pays off, and I know that each day brings me closer to reaching my goals. From small, solo projects to creative collaborations, I’m always looking for the chance to explore new venues and learn something new that I can apply to my work. Currently I am team SME and a Senior Software Engineer @Get My Parking having more than 4.5 years of professional Android development experience.
