Your individuals ought to likewise to be able to tell at a look which object is currently chosen. You can highlight the presently picked object making use of visual hints, such as dimension, shadow, illumination, opacity, as well as computer animation.

Assistance Landscape Mode
Every one of your job’s activities should sustain landscape orientation or your app won’t show up to Android TV customers in the Google Play shop.
If you’re developing an app that can additionally run on tablet computers and smart devices, know that if your project has android: screenOrientation=” portrait” the android.hardware.screen.portrait need is implicitly readied to true.
