这个问题是出现在，切换音乐播放的时候，出现-38的问题，问题的原因应该是MediaPlayer没有初始化造成的吧，这篇文章给的一个思路是，切换音乐播放的时候，销毁掉之前的MediaPlayer对象，然后重现创建一个新的MediaPlayer对象
public void playPrepareAsync() {
try {
if (mUrl == null) {
return;
}
destoryMediaPlayer();
mMediaPlayer = new MediaPlayer();
mMediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
mMediaPlayer.setOnCompletionListener(this);
mMediaPlayer.setOnPreparedListener(this);
mMediaPlayer.setOnSeekCompleteListener(this);
mMediaPlayer.setOnErrorListener(this);
mMediaPlayer.setOnBufferingUpdateListener(this);
if (mUrl.startsWith("android.resource://")) {
mMediaPlayer.setDataSource(this, Uri.parse(mUrl));
} else {
mMediaPlayer.setDataSource(mUrl);
}
mMediaPlayer.prepareAsync();
} catch (IllegalArgumentException e) {
e.printStackTrace();
Log.e(TAG, "IllegalArgumentException无法播放" + mUrl);
} catch (IOException e) {
Log.e(TAG, "IOException无法播放" + mUrl);
e.printStackTrace();
} catch (Exception e) {
Log.e(TAG, "Exception无法播放" + mUrl);
setErrPlayState("" + "播放失败 " + e.toString());
}
}
public void destoryMediaPlayer() {
try {
if (mediaPlayer != null) {
mediaPlayer.setOnCompletionListener(null);
mediaPlayer.setOnPreparedListener(null);
mediaPlayer.reset();
mediaPlayer.release();
mediaPlayer = null;
}
} catch (Exception e) {
}
}
