Question

我尝试实现像WhatsApp这样的录制/播放应用功能，如果我加载现有音符，我会在创建新音符或播放侦听器时加载录音监听器。录音没有问题，我无法播放曲目。我在片段的OnCreateView中设置了监听器。

audioSendButton.setOnClickListener(new playerListener(path,audioSendButton,context));

（我编辑了很多代码，对不起，如果我写了一些愚蠢的东西）

    MediaPlayer.OnCompletionListener {

    player = new MediaPlayer();
    initMusicPlayer();

            mp.start();
        }

    Log.i("music_service","created");

这是错误日志，路径正确，它是绝对路径（/storage/emulated/0/Nota-2016.07.20 17：57：23.mp4）

好吧，我在华为P8 Lite上尝试了我的应用程序，所以使用SD卡，它运行得很好，所以问题是我的nexus 5没有sdcards（或者编码/解码系统不好？）。有什么想法解决它？

Android媒体播放器无法播放，很多错误
