我正在尝试实现exoplayer这是我的exoplayer版本

  1. implementation 'com.google.android.exoplayer:exoplayer:2.11.1'

我正在创建一个音乐播放器应用程序，我不知道任何关于exoplayer我试图实现exoplayer从过去2天，但它不工作.官方文件里的东西我一点也看不懂。
我找到了很多例子和教程，但都是关于使用exoplayer播放视频。很多例子都使用了过时的方法。
我尝试使用这个tutorial来实现，但是很多方法都被弃用了，所以它不能正常工作。

  1. simpleExoplayer = ExoPlayerFactory.newSimpleInstance(
  2.             DefaultRenderersFactory(this),
  3.             DefaultTrackSelector(adaptiveTrackSelectionFactory),
  4.             DefaultLoadControl()
  5.         )

任何人都可以建议我从哪里开始，或者我如何使用最新版本的exoplayer构建音乐流媒体应用程序。
如有任何帮助，我们将不胜感激。

通过新的更新，您可以使用SimpleExoPlayer.Builder创建一个简单的播放器示例：

  1. simpleExoplayer = SimpleExoPlayer.Builder(context).build()

您还可以为Builder提供不同的参数。参见https://exoplayer.dev/doc/reference/com/google/android/exoplayer2/SimpleExoPlayer.Builder.html
您可以使用我创建的这个简单的自定义类来帮助您入门。

  1. class ExoPlayerHelper(
  2.     private val playerView: PlayerView,
  3.     onError: (ExoPlaybackException) -> Unit,
  4.     onPlayerBuffer: (Boolean) -> Unit
  5. ) {
  7.     private var exoPlayer: ExoPlayer? = null
  8.     private var mediaSource: ProgressiveMediaSource? = null
  10.     private val playerListener = object : Player.EventListener {
  11.         override fun onPlayerError(error: ExoPlaybackException) {
  12.             super.onPlayerError(error)
  13.             onError(error)
  14.         }
  16.         override fun onPlayerStateChanged(playWhenReady: Boolean, playbackState: Int) {
  17.             super.onPlayerStateChanged(playWhenReady, playbackState)
  18.             onPlayerBuffer(playbackState == Player.STATE_BUFFERING)
  19.         }
  20.     }
  22.     fun initializePlayer(url: String) {
  23.         exoPlayer = SimpleExoPlayer.Builder(playerView.context).build()
  24.         exoPlayer!!.repeatMode = Player.REPEAT_MODE_ALL
  25.         exoPlayer!!.addListener(playerListener)
  27.         playerView.player = exoPlayer
  29.         val userAgent =
  30.             Util.getUserAgent(playerView.context, playerView.context.getString(R.string.app_name))
  31.         mediaSource = ProgressiveMediaSource
  32.             .Factory(
  33.                 DefaultDataSourceFactory(playerView.context, userAgent),
  34.                 DefaultExtractorsFactory()
  35.             )
  36.             .createMediaSource(Uri.parse(url))
  38.         exoPlayer!!.prepare(mediaSource!!, true, false)
  39.         exoPlayer!!.playWhenReady = true
  40.     }
  42.     private fun killPlayer() {
  43.         if (exoPlayer != null) {
  44.             exoPlayer!!.release()
  45.             exoPlayer = null
  46.             mediaSource = null
  47.             playerView.player = null
  48.         }
  49.     }
  50. }

我也面临这个问题，这是我的解决方案

Declaration

  1. private val exoPlayer: SimpleExoPlayer by lazy { SimpleExoPlayer.Builder(this).build()}

播放歌曲

  1. private fun prepareExoPlayerFromURL(url: String) {
  2.         val dataSourceFactory =
  3.             DefaultDataSourceFactory(this, Util.getUserAgent(this, resources.getString(R.string.app_name)), null)
  4.         val extractorsFactory = DefaultExtractorsFactory()
  5. //        val audioSource = ExtractorMediaSource(uri, dataSourceFactory, extractorsFactory, null, null)
  7.         val concateMediaSource = ConcatenatingMediaSource()
  9.         // to play from song list
  10.         for (i in mSongList) {      // song list song arraylist
  11.             val mediaSource = ProgressiveMediaSource
  12.                 .Factory(
  13.                     DefaultDataSourceFactory(this, dataSourceFactory),
  14.                     DefaultExtractorsFactory()
  15.                 )
  16.                 .createMediaSource(Uri.parse(i.musicFile)/*Uri.parse(i.uri)*/)
  17.             concateMediaSource.addMediaSource(mediaSource)
  18.         }
  20.         // to play single song
  21.        /* val audioSource = ProgressiveMediaSource
  22.             .Factory(
  23.                 DefaultDataSourceFactory(this, dataSourceFactory),
  24.                 DefaultExtractorsFactory()
  25.             )
  26.             .createMediaSource(Uri.parse(url))*/
  28.         exoPlayer.prepare(concateMediaSource/*audioSource*/)
  29.         exoPlayer.seekToDefaultPosition(songPosition)
  30.         exoPlayer.playWhenReady = true
  32.         setNotification()
  33.     }

设置播放器和通知的**监听器

  1. private fun setListoner() {
  2.         exoPlayer.addListener(object : Player.EventListener {
  3.             override fun onPlayerStateChanged(playWhenReady: Boolean, playbackState: Int) {
  4.                 when (playbackState) {
  5.                     Player.STATE_BUFFERING -> Log.e(TAG,"STATE_BUFFERING")
  6.                     Player.STATE_ENDED -> Log.e(TAG,"STATE_ENDED")
  7.                     Player.STATE_IDLE -> Log.e(TAG,"STATE_IDLE")
  8.                     Player.STATE_READY ->{
  9.                         if (playWhenReady) {
  10.                             Log.e(TAG, "PlaybackStatus.PLAYING")
  11.                         } else {
  12.                             Log.e(TAG, "PlaybackStatus.PAUSED")
  13.                         }
  14.                     }
  15.                     else -> Log.e(TAG,"PlaybackStatus.IDLE")
  16.                 }
  17.             }
  18.         })
  19.     }

杀死玩家

  1. private fun onDestroy() {
  2.         if (exoPlayer != null) {
  3.             exoPlayer.release()
  4.             exoPlayer = null
  5.             mediaSource = null
  6.         }
  7.     }

在2.15.0版本之前，您可以按以下方式创建SimpleExoPlayer示例：

  1. SimpleExoPlayer.Builder(this)
  2.             .setMediaSourceFactory(mediaSourceFactory)
  3.             .build()

在2.16.0版本中，不推荐使用SimpleExoPlayer，您应该改用ExoPlayer示例。可以按以下方式创建：

  1. ExoPlayer.Builder(this)
  2.             .setMediaSourceFactory(mediaSourceFactory)
  3.             .build()

1.调用此方法：

  1. private void initializePlayer() {
  2.          FloatingWidgetService.hidePipPlayer();
  4.          binding.videoOverlay.setVisibility(View.GONE);
  5.          liveTvexoPlayer = new SimpleExoPlayer.Builder(context).build();
  6.          binding.playerView.setPlayer(liveTvexoPlayer);
  7.          binding.playerView.setResizeMode(AspectRatioFrameLayout.RESIZE_MODE_FIT);
  8.          binding.playerView.setUseController(true);
  10.          liveTvexoPlayer.setPlayWhenReady(true);
  11.          liveTvexoPlayer.seekTo(0);
  12.          appManageInterface.setLiveTvVideo(playBackUrl, "getReady", 0);
  13.          Prefs.getPrefInstance().setValue(context, Const.VIDEO_URL, playBackUrl);
  15.          imgViewChangeScreenOrientation = binding.playerView.findViewById(R.id.exo_fullscreen_icon);
  16.          imgViewChangeScreenOrientation.setOnClickListener(new View.OnClickListener() {
  17.              @Override
  18.              public void onClick(View v) {
  19.                  liveTvexoPlayer.setPlayWhenReady(false);
  20.                  liveTvexoPlayer.release();
  21.                  Intent serviceIntent = new Intent(context, FloatingWidgetService.class);
  22.                  serviceIntent.putExtra("videoUri", playBackUrl);
  23.                  serviceIntent.putExtra("isfrom", "livetv");
  24.  //                serviceIntent.putExtra("videoUri", "https://commondatastorage.googleapis.com/gtv-videos-bucket/sample/SubaruOutbackOnStreetAndDirt.mp4");
  25.                  getActivity().startService(serviceIntent);
  26.              }
  27.          });
  29.          AudioAttributes audioAttributes = new AudioAttributes.Builder()
  30.                  .setUsage(C.USAGE_MEDIA)
  31.                  .setContentType(C.CONTENT_TYPE_MOVIE)
  32.                  .build();
  33.          if (liveTvexoPlayer.getAudioComponent() != null)
  34.              liveTvexoPlayer.getAudioComponent().setAudioAttributes(audioAttributes, true);
  35.          try {
  36.              if (!playBackUrl.equals("")) {
  37.                  DataSource.Factory dataSourceFactory = new DefaultDataSourceFactory(context, Util.getUserAgent(context, getResources().getString(R.string.app_name)));
  38.                  MediaSource videoSource = new HlsMediaSource.Factory(dataSourceFactory).createMediaSource(Uri.parse(playBackUrl));
  39.                  liveTvexoPlayer.prepare(videoSource, true, true);
  40.              }
  41.          } catch (Exception e) {
  43.          }
  44.          liveTvexoPlayer.addListener(new Player.EventListener() {
  45.              @Override
  46.              public void onPlayerStateChanged(boolean playWhenReady, int playbackState) {
  47.              }
  49.              @Override
  50.              public void onPlayerError(ExoPlaybackException error) {
  51.                  switch (error.type) {
  52.                      case TYPE_SOURCE:
  53.                          binding.videoOverlay.setVisibility(View.VISIBLE);
  54.                          break;
  55.                      case TYPE_RENDERER:
  56.                      case TYPE_UNEXPECTED:
  57.                          liveTvexoPlayer.retry();
  58.                          break;
  59.                      case TYPE_OUT_OF_MEMORY:
  60.                      case TYPE_REMOTE:
  61.                          AppUtil.show_Snackbar(context, binding.playerView, error.getMessage(), true);
  62.                          break;
  63.                  }
  64.              }
  65.          });
  66.      }

1.使用以下方法管理exoplayer：

  1. @Override
  2.     public void onResume() {
  3.         super.onResume();
  4.         mTracker.setScreenName("Screen - " + "Live Tv");
  5.         mTracker.send(new HitBuilders.ScreenViewBuilder().build());
  6.         binding.playerView.onResume();
  7.         if (liveTvexoPlayer != null)
  8.             liveTvexoPlayer.setPlayWhenReady(true);
  9.     }
  11.     @Override
  12.     public void onStart() {
  13.         super.onStart();
  14.         binding.playerView.onResume();
  15.         if (liveTvexoPlayer != null)
  16.             liveTvexoPlayer.setPlayWhenReady(true);
  17.     }
  19.     @Override
  20.     public void onPause() {
  21.         binding.playerView.onPause();
  22.         if (liveTvexoPlayer != null) {
  23.             liveTvexoPlayer.setPlayWhenReady(false);
  24.         }
  25.         super.onPause();
  26.     }
  28.     @Override
  29.     public void onStop() {
  30.         binding.playerView.onPause();
  31.         if (liveTvexoPlayer != null)
  32.             liveTvexoPlayer.setPlayWhenReady(false);
  33.         super.onStop();
  34.     }
  36.     @Override
  37.     public void onDestroy() {
  38.         binding.playerView.onPause();
  39.         if (liveTvexoPlayer != null) {
  40.             liveTvexoPlayer.release();
  41.             liveTvexoPlayer = null;
  42.         }
  43.         super.onDestroy();
  44.     }
