java - Exoplayer 的 Ooyala SDK - NoClassDefFoundError : com. ooyala.android.player.exoplayer.ExoStreamPlayer

Question

情况:将我的 Android 项目从带有 VisualOn 的旧 Ooyala SDK 更新到带有 Exoplyer 的最新 Ooyala SDK。通过 Amazon Fire Stick 播放视频。

问题:更新 SDK 后，该项目不再运行。我们收到此错误消息:

• “E/AndroidRuntime:致命异常:main 进程:com.ISN.firetv_isn，PID:19650 java.lang.NoClassDefFoundError: com.ooyala.android.player.exoplayer.ExoStreamPlayer"

查看 NoClassDefFoundError，我觉得代码缺少包的导入(但是，总的来说我不知道​​)。

.

请帮我定位问题。解决方案是什么？
