您是否在清单文件上放置了正确的权限？由于您使用的是唱机，因此您可能需要使用：

`<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />`

编辑：还要确保您在清单文件上也使用正确的API目标例如： <uses-sdk android:minSdkVersion="8" android:targetSdkVersion="19" />

Phono android SDK，音频适用于android 4.4.2，但不适用于其他版本
