Question

我正在使用AudioTrack的额外线程来播放我之前在另一项活动中录制的wave文件。

当我开始播放时，我在LogCat中获得以下输出：

Answer 1

我之前遇到过同样的问题。我使用了vitamio bundle，这是Android的Media Player的对应物，并且有更多的音频支持。尝试将此代码添加到清单中：

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

我希望这会有所帮助。

Answer 2

当写入的样本数量不能被通道数整除时，我发现了同样的问题。

例如：

频道数量：2

mAudioTrack.write（buffer，0,75）;

Android AudioTrack仅在前2秒播放，然后停止播放
