状況： AndroidプロジェクトをVisualOnで古いOoyala SDKからExoplyerで最新のOoyala SDKにアップデートしました。 Amazon Fire Stickを介してビデオを再生します。Ooyala SDK for Exoplayer - NoClassDefFoundError：com.ooyala.android.player.exoplayer.ExoStreamPlayer
問題： SDKをアップデートした後、プロジェクトはもう機能しません。
- 「E/AndroidRuntime：致命的な例外：メイン プロセス：com.ISN.firetv_isn、PID：19650 java.lang.NoClassDefFoundErrorが：com.ooyala.android.player.exoplayer私たちは、このエラーメッセージが表示されます。 ExoStreamPlayer "
NoClassDefFoundErrorを見ると、コードにパッケージのインポートがないように感じられます（しかし、全体的には分かりません）。
。
問題の原因を調べてください。解決策は何でしょうか？
