android – MediaPlayer认为aac *音频文件是一个视频文件？

概述代码运行正常,但我正在设置这个Erro日志 Erro日志： 08-28 08:44:24.281: E/MediaPlayer(32454): mOnVideoSizeChangedListener is null. Failed to send MEDIA_SET_VIDEO_SIZE message. 我尝试将音频文件转换为不同格式的设置监听器等等…… 我真的需要这个帮助.她是整个MediaP 代码运行正常,但我正在设置这个Erro日志

Erro日志：

08-28 08:44:24.281: E/MediaPlayer(32454): mOnVIDeoSizeChangedListener is null. Failed to send MEDIA_SET_VIDEO_SIZE message.

我尝试将音频文件转换为不同格式的设置监听器等等……
我真的需要这个帮助.她是整个MediaPlayer日志：

和Java代码.

Java代码：

public class MainActivity extends Activity {    MediaPlayer TestingAudio;    @OverrIDe    public voID onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        Initialization();        DoStuff();    }    private voID Initialization() {        setContentVIEw(R.layout.activity_main);        TestingAudio = MediaPlayer.create(MainActivity.this,R.raw.samlagnin);    }    private voID DoStuff() {        TestingAudio.start();    }    @OverrIDe    protected voID onPause() {        super.onPause();        TestingAudio.release();        TestingAudio = null;    }

解决方法 我设法通过附加一些空的侦听器来摆脱错误.请参阅 http://developer.android.com/reference/android/media/MediaPlayer.html中的setonPreparedListener()和类似方法 @H_301_38@ 总结
