Audio Android 5.0设备上的ExoPlayer未完全播放音频文件，在Android 9上正常

我正在使用Exoplayer播放简短的mp3（语音）文件，我的代码在运行Android 9的Moto G6上运行良好，我一直在使用它开发应用程序。但是在安卓5.0上的三星S4上运行它，在每段视频结束时大约半秒不会播放

我使用的是Exoplayer，因为用户通常可以选择以慢速播放剪辑，我知道MediaPlayer不会在空闲时这样做 10-04 15:20:25.380 8358-8358/com.englishdreaming.apply D/EventLogger:decoderInitialized[0.26,0.00，window=0，period=0，audio，OMX.SEC.mp3.dec] 10-04 15:20:25.380 8358-8358/com.englishdreaming.apply D/EventLogger:decoderInputFormatChanged[0.26,0.00，window=0，period=0，audio，id=null，mimeType=audio/mpeg，channels=2，sample_rate=44100] 10-04 15:20:25.380 8358-8358/com.englishdreaming.apply D/EventLogger:加载[0.26,0.00，窗口=0，周期=0，假] 10-04 15:20:25.380 8358-8636/com.englishdreaming.apply I/ACodec:[OMX.SEC.mp3.dec]现在空闲->执行 10-04 15:20:25.380 8358-8358/com.englishdreaming.apply D/EventLogger:state[0.26,0.00，window=0，period=0，true，READY] 10-04 15:20:25.380 8358-8636/com.englishdreaming.apply I/ACodec:[OMX.SEC.mp3.dec]正在执行 10-04 15:20:25.390 8358-8358/com.englishdreaming.apply D/EventLogger:downstreamFormatChanged[0.27,0.00，window=0，period=0，id=null，mimeType=audio/mpeg，channels=2，sample_rate=44100] 10-04 15:20:25.420 8358-8625/com.englishdreaming.apply E/AudioTrack:AudioTrack:：set:Exit 10-04 15:20:25.420 8358-8358/com.englishdreaming.apply D/EventLogger:audioSessionId[0.31,0.00，window=0，period=0944] 10-04 15:20:25.901 8358-8410/com.englishdreaming.apply V/FA：不活动，断开与服务的连接 10-04 15:20:25.911 8358-8358/com.englishdreaming.apply V/FA:onUnbind请求意向。操作：com.google.android.gms.measurement.START 10-04 15:20:25.911 8358-8358/com.englishdreaming.apply V/FA:本地应用测量服务正在关闭 10-04 15:20:26.481 8358-8358/com.englishdreaming.apply D/EventLogger:state[1.37,0.92，window=0，period=0，true，end] 10-04 15:20:26.481 8358-8358/com.englishdreaming.apply I/ExoPlayerImpl:Release 3dfb35fd[ExoPlayerLib/2.8.4][jflte，GT-I9505，三星，21][goog.exo.core] 10-04 15:20:26.491 8358-8636/com.englishdreaming.apply I/ACodec:[OMX.SEC.mp3.dec]正在执行->空闲 10-04 15:20:26.501 8358-8636/com.englishdreaming.apply I/ACodec:[OMX.SEC.mp3.dec]现在空闲->加载 10-04 15:20:26.501 8358-8636/com.englishdreaming.apply I/ACodec:[OMX.SEC.mp3.dec]现在已加载 10-04 15:20:26.511 8358-8636/com.englishdreaming.apply I/ACodec:[OMX.SEC.mp3.dec]现在未初始化 10-04 15:20:26.531 8358-8358/com.englishdreaming.apply D/EventLogger:decoderDisabled[1.41,0.92，window=0，period=0，audio] 10-04 15:20:26.531 8358-8358/com.englishdreaming.apply D/EventLogger:mediaPeriodReleased[1.41,0.92，window=0，period=0]
