I downloaded the google project from git repo link: https://github.com/googlesamples/androidtv-sample-inputs. But I am unable to find the understanding of module for the below-mentioned layout. I need to create channel and EPG view exactly same as the below-mentioned diagram, using the android lean-back library and TV Input framework concepts. So, kindly provide me with the understanding of the project as where I can find the working of this module.
The guide you see here is part of a reference TV App aka Live Channels which is a system app and ships with every Android TV system image. It is open-sourced under Apache 2.0 and you can check out the details and source code here:
https://source.android.com/devices/tv/reference-tv-app https://android.googlesource.com/platform/packages/apps/TV/
It uses a different build system than Gradle but you should be able to refactor it to use Gradle.
EDIT: A nice alternative TV guide for Android TV recently appeared on GitHub here: https://github.com/egeniq/android-tv-program-guide
