私は、アプリケーションでHLSビデオを再生するためにexoplayerを使用しています。問題は私がBehindLiveWindowExceptionを得ていることと、その例外が発生した場合にプレイヤーを再初期化する解決策を発見したことです。しかし、どういうわけか私はクラスでその例外を捕らえることができないので、プレイヤーを再初期化することができます。ExoPlayer - BehindLiveWindowExceptionをキャッチできません
代わりに、logcatでBLWE例外を見ることができますが、プレーヤーを再起動することはありません。
誰かが私が間違って何をやっている私を伝えることができますしてください、私のコードスニペットはここにある：私は解決策を見つけた
