Failed to apply plugin Android Studio
It looks like gradle could not find this plugin in all specified repositories. ExoPlayer specifies buildscript repositories in the root project, so that's what you should do too.
In your root build.gradle make sure buildscript section contains jcenter() repository and 'andcom.novoda:bintray-release:0.2.7' classpath:
buildscript { repositories { ...... <- whatever you have now jcenter() <- make sure this one is there } dependencies { ...... <- whaterver you have now classpath 'com.novoda:bintray-release:0.2.7' <- make sure this one is there }}
