how to increase the resolution of a video in Android

Answer 1

I think your question will be more suitable in other forum such as https://www.xda-developers.com/

Answer 2

Don't think you should ever increase the resolution of a video in android as it uses more memory and looks blurry

I have used many videos in android apps, trying to think of the package you add, it adjust the video resolution for the device your playing the video on, also videos can be large and android apps are limited to a small size (50MB) apk
