Issue Duplicate class exoplayer

[Kadaluarsa]

Hi guys I have an issue when I integrate qiscus, here is the stacktrace :
`* What went wrong:
Execution failed for task ':app:checkEvermosFreeDebugDuplicateClasses'.

A failure occurred while executing com.android.build.gradle.internal.tasks.CheckDuplicatesRunnable
Duplicate class com.google.android.exoplayer2.ui.package-info found in modules jetified-exoplayer-common-2.14.1-runtime (com.google.android.exoplayer:exoplayer-common:2.14.1) and jetified-exoplayer-ui-2.12.0-runtime (com.google.android.exoplayer:exoplayer-ui:2.12.0)`

here is a similar issue: https://translate.google.com/translate?sl=auto&tl=en&u=https://zhuanlan.zhihu.com/p/388052240
the exoplayer should be upgraded to 2.14.1
