#播放在线音频问题报错MediaPlayer error

这里对Android播放在线音频报错的情况做一下简单经验总结。

如果报错：MediaPlayer error (1, -2147483648)

有两种可能： 1、这个网址是不正确的 2、这个音频文件的编码格式，手机不支持 3、还有可能电脑端浏览器能访问，但是都是手机端访问返回403，这个我就遇到了。上面的情况，一般播放在线音频文件的预加载模式时间会比较久，有时候20多秒.才显示播放失败！第一种情况和第三种情况其实都是差不多，都是访问没有返回200的访问码。

如果报错：E/MediaPlayerNative: error (1, -19)

就是Media状态不对的情况下播放比如： 1、MediaPlayerNative 没有回收需要在播放完成或者停止的时候把对象释放。 mediaPlayer.reset(); mediaPlayer.release();

2、设置错误的播放流类型比如设置成播放闹铃类型，这个可能要特殊权限或者其他设置，反正会报错。 MediaPlayer.setAudioStreamType(AudioAttributes.USAGE_NOTIFICATION_RINGTONE); 这个熟悉一般不设置或者设置成MUSIC类型就可以啦。

在线音频播放前最好，判断一下是否能接收数据，然后再播放。

如下判断连接的url地址返回的状态的代码：

/** * 判断连接的url地址返回的状态，必须在子线程运行否则报错null * * @param address * @return */ public int getUrlConnectionState(String address) { int status = HttpURLConnection.HTTP_NOT_FOUND; try { URL urlObj = new URL(address); HttpURLConnection oc = (HttpURLConnection) urlObj.openConnection(); oc.setUseCaches(false); oc.setConnectTimeout(3000); // 设置超时时间 oc.connect(); status = oc.getResponseCode();// 请求状态 if (HttpURLConnection.HTTP_OK == status) { return status; } } catch (Exception e) { Log.e(TAG, " Media getUrlConnectionState error=" + e.getMessage()); } return status; }

如果返回的值为HttpURLConnection.HTTP_OK（200），说明能正常连通。

完整的控制在线音频文件的示例代码：

private staticTimer timer = new Timer(); private static MediaPlayer mOnlineMediaPlayer; //背景音频文件对象 private IActionListener mOnlineMediaListener = null; /** * 播放在线音频文件 * * @param url * @param loop * @param iActionListener */ public void playOnlineMedia(final String url, final float volume, final boolean loop, final IActionListener iActionListener) { TimerTask timerTask = new TimerTask() { @Override public void run() { playInnerOnlineMedia(url, volume, loop, iActionListener); } }; timer.schedule(timerTask, 0); } public void playInnerOnlineMedia(final String url, float volume, boolean loop, IActionListener iActionListener) { Log.i(TAG, "playOnlineMedia url=" + url + ",volume=" + volume + ",loop=" + loop + ",iActionListener=" + iActionListener); int state = getUrlConnectionState(url); if (state != HttpURLConnection.HTTP_OK) { Log.e(TAG, "playOnlineMedia visit url=" + url + " ,return state:" + state); return; } stopOnlineMedia(); mOnlineMediaListener = iActionListener; mOnlineMediaPlayer = new MediaPlayer(); try { //音频播放完毕,回调onCompletion方法 mOnlineMediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() { @Override public void onCompletion(MediaPlayer mp) { Log.i(TAG, "playOnlineMedia onCompletion url=" + url); if (mOnlineMediaListener != null) { onActionListener(true, mOnlineMediaListener); } mOnlineMediaListener = null; } }); mOnlineMediaPlayer.setDataSource(url); mOnlineMediaPlayer.setLooping(loop); mOnlineMediaPlayer.setVolume(volume, volume); mOnlineMediaPlayer.setOnErrorListener(new MediaPlayer.OnErrorListener() { @Override public boolean onError(MediaPlayer mp, int what, int extra) { Log.e(TAG, "playOnlineMedia setOnErrorListener what=" + what + ",extra=" + extra); return false; } }); mOnlineMediaPlayer.setAudioStreamType(AudioAttributes.USAGE_NOTIFICATION_RINGTONE); mOnlineMediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() { @Override public void onPrepared(MediaPlayer mp) { Log.i(TAG, "playOnlineMedia onPrepared url=" + url); if (mOnlineMediaPlayer != null) { mp.start(); } } }); mOnlineMediaPlayer.prepareAsync(); onActionListener(false, iActionListener); } catch (IOException e) { Log.e(TAG, "playOnlineMedia.start error=" + e.getMessage()); e.printStackTrace(); } } /** * 停止在线音频文件播放 */ public void stopOnlineMedia() { Log.e(TAG, "stopOnlineMedia "); if (mOnlineMediaPlayer != null) { try { if (mOnlineMediaPlayer.isPlaying()) { mOnlineMediaPlayer.stop(); } mOnlineMediaPlayer.release(); } catch (IllegalStateException e) { Log.e(TAG, "stopOnlineMedia error=" + e.getMessage()); } if (mOnlineMediaListener != null) { onActionListener(true, mOnlineMediaListener); } mOnlineMediaPlayer = null; mOnlineMediaListener = null; } } /** * 暂停在线音频文件播放 */ public void pauseOnlineMedia() { Log.e(TAG, "pauseOnlineMedia "); if (mOnlineMediaPlayer != null) { try { if (mOnlineMediaPlayer.isPlaying()) { mOnlineMediaPlayer.pause(); } } catch (IllegalStateException e) { Log.e(TAG, "pauseOnlineMedia error=" + e.getMessage()); } } } /** * 恢复在线音频文件播放 */ public void resumeOnlineMedia() { Log.e(TAG, "resumeOnlineMedia "); if (mOnlineMediaPlayer != null) { try { if (!mOnlineMediaPlayer.isPlaying()) { mOnlineMediaPlayer.start(); } } catch (IllegalStateException e) { Log.e(TAG, "resumeOnlineMedia error=" + e.getMessage()); } } } /** * 判断音频文件是否在播放 * * @return */ public boolean isOnlineMediaPlaying() { try { if (mOnlineMediaPlayer != null && mOnlineMediaPlayer.isPlaying()) { return true; } } catch (IllegalStateException e) { Log.e(TAG, "isOnlineMediaPlaying error=" + e.getMessage()); } return false; } /** * 判断连接的url地址返回的状态，必须在子线程运行否则报错null * * @param address * @return */ public int getUrlConnectionState(String address) { int status = HttpURLConnection.HTTP_NOT_FOUND; try { URL urlObj = new URL(address); HttpURLConnection oc = (HttpURLConnection) urlObj.openConnection(); oc.setUseCaches(false); oc.setConnectTimeout(3000); // 设置超时时间 oc.connect(); status = oc.getResponseCode();// 请求状态 if (HttpURLConnection.HTTP_OK == status) { return status; } } catch (Exception e) { Log.e(TAG, " Media getUrlConnectionState error=" + e.getMessage()); } return status; }

播放状态接口IActionListener

interface IActionListener { /** * 行为开始 */ void onStart(); /** *行为结束 */ void onEnd(); }
