Exoplayer video format setting button in Android

Hi, Just I need one page application which have latest 2.9.1 version Exoplayer. 1. Edittext for entering url and than ok button. 2. Exoplayer view to play that url and custom setting button in the player in which we can change video format. Language: Kotlin/Java as you prefer. That's it. Hope this will be very easy task who know about Exoplayer. Thanks.
