android background image slows down app

Question

I am using a viewpager to swipe amongst fragments in my app. I define the background in the XML, so

android:background=\"@drawable/bg_final\"

Answer 1

The reason for this could be that the image is being stretched, and Android has performance issues with stretching background images.

Instead, you should either replace the background image with either a background color or see this answer to have the image repeat instead of stretch.
