exoplayer和mediaplayer的封装

问题：开发播放器的过程中发现，在mediaplayer对喜马拉雅的hls直播音频流进行播放的过程中，发生MediaPlayer:Error(1,-1007)错误，尝试播放网上找的直播流"http://content.mobile-tv.sky.com/content/ssna/live/ssnraudio.m3u8"不放生此问题

对此在不改变项目已有接口的情况下将MediaPlayer 和 ExoPlayer进行封装

代码如下

public class MediaPlayerImp {private UaiMediaListener listener;private Context context;private boolean isExoPLayer = false;private Object mMediaPlayer;private Object exoPlayerListener;public interface UaiMediaListener {void onPrepared();void onCompletion();void onSeekComplete();void onError();}public MediaPlayerImp(Context context) {this.context = context;mMediaPlayer = createMediaPlayer(context);}public MediaPlayerImp(Context context, boolean isNeedExoPLayer){this(context);this.isExoPLayer = isNeedExoPLayer;}public void reset() {if (isExoPLayer) {//no reset do nothing} else {((MediaPlayer) mMediaPlayer).reset();}}public boolean isPlaying() {if (isExoPLayer) {return ((ExoPlayer) mMediaPlayer).getPlayWhenReady();} else {return ((MediaPlayer) mMediaPlayer).isPlaying();}}public void start() {if (isExoPLayer) {((ExoPlayer) mMediaPlayer).setPlayWhenReady(true);} else {((MediaPlayer) mMediaPlayer).start();}}public void pause() {if (isExoPLayer) {((ExoPlayer) mMediaPlayer).setPlayWhenReady(false);} else {((MediaPlayer) mMediaPlayer).pause();}}public void stop() {if (isExoPLayer) {((ExoPlayer) mMediaPlayer).setPlayWhenReady(false);((ExoPlayer) mMediaPlayer).stop();} else {((MediaPlayer) mMediaPlayer).stop();}}public void release() {if (isExoPLayer) {((ExoPlayer) mMediaPlayer).removeListener((Player.EventListener) exoPlayerListener);((ExoPlayer) mMediaPlayer).release();} else {((MediaPlayer) mMediaPlayer).release();}}public void seekTo(int msec) {if (isExoPLayer) {((ExoPlayer) mMediaPlayer).seekTo(msec);} else {((MediaPlayer) mMediaPlayer).seekTo(msec);}}public void playAsync(String strUri) {if (isExoPLayer) {DataSource.Factory dataSourceFactory = new DefaultDataSourceFactory(context, "MediaPlayerImp");if (strUri.endsWith("m3u8")) {MediaSource hlsMediaSource = new HlsMediaSource.Factory(dataSourceFactory).createMediaSource(Uri.parse(strUri));((ExoPlayer) mMediaPlayer).prepare(hlsMediaSource, true, true);} else {MediaSource extraMediaSource = new ExtractorMediaSource.Factory(dataSourceFactory).createMediaSource(Uri.parse(strUri));((ExoPlayer) mMediaPlayer).prepare(extraMediaSource);}} else {try {((MediaPlayer) mMediaPlayer).setDataSource(strUri);((MediaPlayer) mMediaPlayer).prepareAsync();} catch (IOException e) {e.printStackTrace();}}}public long getDuration() {if (isExoPLayer) {return ((ExoPlayer) mMediaPlayer).getDuration();} else {return ((MediaPlayer) mMediaPlayer).getDuration();}}public long getCurrentPosition() {if (isExoPLayer) {return ((ExoPlayer) mMediaPlayer).getCurrentPosition();} else {return ((MediaPlayer) mMediaPlayer).getCurrentPosition();}}public void setUaiMediaListener(@NonNull UaiMediaListener listener) {this.listener = listener;}private Object createMediaPlayer(Context context) {if (isExoPLayer) {// Create the playerExoPlayer exoPlayer = ExoPlayerFactory.newSimpleInstance(new DefaultRenderersFactory(context),new DefaultTrackSelector(), new DefaultLoadControl());exoPlayerListener = new Player.DefaultEventListener() {@Overridepublic void onPlayerStateChanged(boolean playWhenReady, int playbackState) {if (playbackState == Player.STATE_READY) {listener.onPrepared();}if (playbackState == Player.STATE_ENDED) {listener.onCompletion();}}@Overridepublic void onPlayerError(ExoPlaybackException error) {listener.onError();}@Overridepublic void onSeekProcessed() {listener.onSeekComplete();}};exoPlayer.addListener((Player.EventListener) exoPlayerListener);return exoPlayer;} else {MediaPlayer mediaPlayer = new MediaPlayer();mediaPlayer.setOnPreparedListener((mp) -> {listener.onPrepared();});mediaPlayer.setOnErrorListener((mp, what, extra) -> {listener.onError();return true;});mediaPlayer.setOnCompletionListener((mp) -> {listener.onCompletion();});mediaPlayer.setOnSeekCompleteListener((mp) -> {listener.onSeekComplete();});return mediaPlayer;}}}

这样实现在不改变原项目有接口的基础上进行播放器的适配
