问题描述
我正在使用Exoplayer播放简短的mp3（语音）文件，并且我的代码在运行Android 9的Moto G6上运行正常，我一直在使用它来开发应用程序。但是在Android 5.0上的Samsung S4上运行它时，每个剪辑的结尾不会播放大约半秒。
我正在使用Exoplayer，因为用户通常可以选择以慢速播放剪辑，并且我知道MediaPlayer在
我要发布我的Exoplayer方法和调用后每个设备的堆栈跟踪-我添加了一个事件记录器。我不知道为什么5.0设备堆栈跟踪中有行引用视频而其他行没有，但我怀疑行'10 -04 15：20：25.420 8358-8625 / com.englishdreaming.appily E / AudioTrack： AudioTrack :: set：“退出”可能对比我更好地阅读堆栈跟踪的人有所帮助-它采用致命异常的方式进行着色，并且仅在5.0堆栈跟踪中发生。
在开发的早期，我记得在Android 9设备上有一个类似的问题，即音频文件的结尾被切断了，但是我不记得我是如何解决的，或者它是否解决了本身-但现在在9上可以正常使用，但在5.0上却不能。非常感谢您提出有关如何立即修复的任何想法。
