Exoplayer

Question

을 사용하여 개발중인 Podcast 앱에서 미디어 스타일 알림을 사용할 수 있습니까? 미디어 스타일 알림 예 https://www.binpress.com/tutorial/using-android-media-style-notifications-with-media-session-controls/165을 모두 통과 했으므로 Media Player를 사용하고 있습니다. 내 질문에 Exoplayer를 사용할 수 있습니다.

Exoplayer 앱에서도 동일한 작업을 수행하고 싶습니다. 어떤 아이디어? 여기

내가 지금 뭐하는 거지 무엇

나는 배경 색상을 사용자 정의 할 수 있기 때문에 그것을 MediaStyle을 방법을하고 싶지 그것은 또한 훨씬 간단하게 구현이 느끼는 이유 스타일.

Answer 1

예, ExoPlayer에서 MediaStyle 알림을 사용할 수 있습니다. 사실, 당신은 포함 Best practices in media playback의 숫자를 구현해야합니다

• 오디오 초점
• BECOMING_NOISY 방송
• MediaSession
• MediaStyle을 통지
전경 서비스 것을 포함
• 서비스 수명주기
• UI를 동기화 상태로 유지

ExoPlayer는 이러한 것들을 처리하지 않습니다.
