最新因为要做个视频，音乐播放的项目，因为需要做常驻通知，所以网上搜了一大堆，结果一个也不行，现在将最新的代码发出来，没有自定义通知栏，用的系统自带的媒体播放栏，Android最新版本已支持，不同Android厂商的展示效果会有差异，可以支持
1.自有播放器控制通知栏的播放，暂停，上一个，下一个，进度播放
2.通知栏控制播放器的播放，暂停，上一个，下一个，进度播放

1.首先是一个通知管理类(这里参照的其他博主的通知管理类，但是他那个MediaSession的构造方法在Android 14上会崩溃 PS:我估计在Andoird 12上都会崩溃，但是我只有Android14的手机)

package com.anssy.bookvideo.utils.music;import android.annotation.SuppressLint;

}

2.MediaSession类，这个是播放通知栏控制播放器的操作类

package com.anssy.bookvideo.utils.music;import android.app.PendingIntent;
import android.content.ComponentName;
import android.content.Context;
import android.content.Intent;
import android.graphics.Bitmap;
import android.graphics.drawable.Drawable;
import android.os.Handler;
import android.support.v4.media.MediaMetadataCompat;
import android.support.v4.media.session.MediaSessionCompat;
import android.support.v4.media.session.PlaybackStateCompat;
import android.util.Log;import androidx.annotation.NonNull;
import androidx.annotation.Nullable;import com.bumptech.glide.Glide;
import com.bumptech.glide.request.target.CustomTarget;
import com.bumptech.glide.request.transition.Transition;/*** 主要管理Android 5.0以后线控和蓝牙远程控制播放*/
public class MediaSessionManager {private static final String TAG = "MediaSessionManager";//指定可以接收的来自锁屏页面的按键信息private static final long MEDIA_SESSION_ACTIONS =PlaybackStateCompat.ACTION_PLAY| PlaybackStateCompat.ACTION_PAUSE| PlaybackStateCompat.ACTION_PLAY_PAUSE| PlaybackStateCompat.ACTION_SKIP_TO_NEXT| PlaybackStateCompat.ACTION_SKIP_TO_PREVIOUS| PlaybackStateCompat.ACTION_STOP| PlaybackStateCompat.ACTION_SEEK_TO;private final Context mContext;private MediaSessionCompat mMediaSession;private Handler mHandler;public MediaSessionManager(Context context, Handler handler,Class<?> clazz, PendingIntent pendingIntent) {this.mContext = context;this.mHandler = handler;setupMediaSession(pendingIntent,clazz);}/*** 是否在播放** @return*/protected boolean isPlaying() {//具体去实现return false;}/*** 初始化并激活 MediaSession*/private void setupMediaSession(PendingIntent pendingIntent,Class<?> clazz) {ComponentName componentName = new ComponentName(mContext,clazz);mMediaSession = new MediaSessionCompat(mContext, TAG, componentName,pendingIntent);//指明支持的按键信息类型mMediaSession.setFlags(MediaSessionCompat.FLAG_HANDLES_MEDIA_BUTTONS |MediaSessionCompat.FLAG_HANDLES_TRANSPORT_CONTROLS);mMediaSession.setCallback(callback, mHandler);mMediaSession.setActive(true);}/*** 更新正在播放的音乐信息，切换歌曲时调用*/public void updateMetaData(boolean isMusicPlaying,String url,String name,String resourceName,long duration,long position) {MediaMetadataCompat.Builder metaDta = new MediaMetadataCompat.Builder().putString(MediaMetadataCompat.METADATA_KEY_TITLE, name).putString(MediaMetadataCompat.METADATA_KEY_ARTIST, resourceName).putString(MediaMetadataCompat.METADATA_KEY_ALBUM, resourceName).putString(MediaMetadataCompat.METADATA_KEY_ALBUM_ARTIST, resourceName).putLong(MediaMetadataCompat.METADATA_KEY_DURATION,duration);mMediaSession.setMetadata(metaDta.build());int state = isMusicPlaying ? PlaybackStateCompat.STATE_PLAYING :PlaybackStateCompat.STATE_PAUSED;mMediaSession.setPlaybackState(new PlaybackStateCompat.Builder().setActions(MEDIA_SESSION_ACTIONS).setState(state, position, 1).build());//锁屏页封面设置，高本版没有效果，因为通知栏权限调整。Glide.with(mContext).asBitmap().load(url).into(new CustomTarget<Bitmap>() {@Overridepublic void onResourceReady(@NonNull Bitmap resource, @Nullable Transition<? super Bitmap> transition) {metaDta.putBitmap(MediaMetadataCompat.METADATA_KEY_ALBUM_ART, resource);mMediaSession.setMetadata(metaDta.build());}@Overridepublic void onLoadCleared(@Nullable Drawable placeholder) {}});}public MediaSessionCompat.Token getMediaSession() {return mMediaSession.getSessionToken();}/*** 释放MediaSession，退出播放器时调用*/public void release() {mMediaSession.setCallback(null);mMediaSession.setActive(false);mMediaSession.release();}/*** API 21 以上 耳机多媒体按钮监听 MediaSessionCompat.Callback*/private MediaSessionCompat.Callback callback = new MediaSessionCompat.Callback() {@Overridepublic void onPlay() {//具体自己实现Intent intent = new Intent();intent.setAction(NotifyBuilderManager.ACTION_PLAY_PAUSE);mContext.sendBroadcast(intent);}@Overridepublic void onPause() {Intent intent = new Intent();intent.setAction(NotifyBuilderManager.ACTION_PLAY_PAUSE);mContext.sendBroadcast(intent);}@Overridepublic void onSkipToNext() {Intent intent = new Intent();intent.setAction(NotifyBuilderManager.ACTION_NEXT);mContext.sendBroadcast(intent);}@Overridepublic void onSkipToPrevious() {Intent intent = new Intent();intent.setAction(NotifyBuilderManager.ACTION_PREV);mContext.sendBroadcast(intent);}@Overridepublic void onStop() {}@Overridepublic void onSeekTo(long pos) {Intent intent = new Intent();intent.setAction("seek");intent.putExtra("pos",pos);mContext.sendBroadcast(intent);}};}

3.BroadCastReceiver（广播）

package com.anssy.bookvideo.utils.music;import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;/*** @Description TODO* @Author yulu* @CreateTime 2025年03月26日 11:22:30*/public class MusicBroadcastReceiver extends BroadcastReceiver {@Overridepublic void onReceive(Context context, Intent intent) {}
}

4.Service（常驻服务及后台运行）
 

package com.anssy.bookvideo.utils.music;import android.annotation.SuppressLint;
import android.app.Service;
import android.content.Intent;
import android.os.Binder;
import android.os.IBinder;/*** @Description TODO* @Author yulu* @CreateTime 2025年03月26日 11:27:31*/public class MusicService extends Service {private NotifyBuilderManager notifyBuilderManager;@SuppressLint("NewApi")public void onCreate() {super.onCreate();notifyBuilderManager = new NotifyBuilderManager(this);}public void updateData(String className,boolean isMusicPlaying,String url,String name,String resourceName,long duration,long position){notifyBuilderManager.updateNotification(className,isMusicPlaying,url,name,resourceName,duration,position);}@Overridepublic int onStartCommand(Intent intent, int flags, int startId) {return START_STICKY;}@Overridepublic void onDestroy() {super.onDestroy();notifyBuilderManager.onDestroy();notifyBuilderManager.cancelNotification();}/*** 返回一个Binder对象*/@Overridepublic IBinder onBind(Intent intent) {return new MsgBinder();}public class MsgBinder extends Binder {/*** 获取当前Service的实例* @return*/public MusicService getService(){return MusicService.this;}}
}

至此，核心类已经创建完成

Java调用，请自己根据自己的播放器来实现相关逻辑，播放器对通知栏的控制，请调用Service方法里的updateData（）方法

public class VideoPlayActivity extends BaseActivity{private MusicBroadcastReceiver musicBroadcastReceiver;
private boolean isPlaying;@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);musicBroadcastReceiver = new MusicBroadcastReceiver() {@Overridepublic void onReceive(Context context, Intent intent) {if (intent != null) {String action = intent.getAction();switch (action) {case "com.idujing.play.notify.play_state":if (videoView.isPlaying()) {videoView.pause();} else {videoView.resume();}break;case "com.idujing.play.notify.next":nextData();break;case "com.idujing.play.notify.prev":lastData();break;case "seek":long pos = intent.getLongExtra("pos", 0);videoView.seekTo(pos);break;}}}};IntentFilter intentFilter = new IntentFilter();intentFilter.addAction(NotifyBuilderManager.ACTION_PLAY_PAUSE);intentFilter.addAction(NotifyBuilderManager.ACTION_NEXT);intentFilter.addAction(NotifyBuilderManager.ACTION_PREV);intentFilter.addAction("seek");registerReceiver(musicBroadcastReceiver,intentFilter, RECEIVER_EXPORTED);if("有通知权限"){startMusicService()}  }/*** 常驻监听*/private void  startMusicService() {mIntent = new Intent(this, MusicService.class);bindService(mIntent, conn, Context.BIND_AUTO_CREATE);}private Intent mIntent;private MusicService msgService;private ServiceConnection conn = new  ServiceConnection() {@Overridepublic void onServiceConnected(ComponentName name, IBinder service) {msgService = ((MusicService.MsgBinder)service).getService();}@Overridepublic void onServiceDisconnected(ComponentName name) {}};//仅做展示private addVideoListener(){videoView.addOnStateChangeListener(new BaseVideoView.OnStateChangeListener() {@Overridepublic void onPlayerStateChanged(int playerState) {}@Overridepublic void onPlayStateChanged(int playState) {switch (playState){case BaseVideoView.STATE_PLAYBACK_COMPLETED:isPlaying = false;if (mCurrentPlayType.equals("1")){nextData();}else if (mCurrentPlayType.equals("2")){videoView.replay(true);}if (null!=mIntent){msgService.updateData(VideoPlayActivity.class.getName(),videoView.isPlaying(),mCurrentEntry.imageUrl,mCurrentEntry.name,mCurrentEntry.cateName,videoView.getDuration(),videoView.getCurrentPosition());}break;case BaseVideoView.STATE_BUFFERED:if (null!=mIntent){msgService.updateData(VideoPlayActivity.class.getName(),videoView.isPlaying(),mCurrentEntry.imageUrl,mCurrentEntry.name,mCurrentEntry.cateName,videoView.getDuration(),videoView.getCurrentPosition());}break;case BaseVideoView.STATE_PLAYING:if (!isPlaying){isPlaying = true;if (null!=mIntent){msgService.updateData(VideoPlayActivity.class.getName(),isPlaying,mCurrentEntry.imageUrl,mCurrentEntry.name,mCurrentEntry.cateName,videoView.getDuration(),videoView.getCurrentPosition());}}break;case BaseVideoView.STATE_PAUSED:isPlaying = false;if (null!=mIntent){msgService.updateData(VideoPlayActivity.class.getName(),isPlaying,mCurrentEntry.imageUrl,mCurrentEntry.name,mCurrentEntry.cateName,videoView.getDuration(),videoView.getCurrentPosition());}break;}}});}@Overrideprotected void onDestroy() {super.onDestroy();if (null!=mIntent){stopService(mIntent);}unregisterReceiver(musicBroadcastReceiver);}
}

2.kotlin调用
 

class FormationDetailOneActivity : BaseActivity() { private lateinit var musicBroadcastReceiver: MusicBroadcastReceiverprivate var isPlayIng = falseoverride fun onCreate(savedInstanceState: Bundle?) {super.onCreate(savedInstanceState)mViewBinding = ActivityFormationDetailOneBinding.inflate(layoutInflater)setContentView(mViewBinding.root)musicBroadcastReceiver = object : MusicBroadcastReceiver(){override fun onReceive(context: Context?, intent: Intent?) {if (intent!=null){val action = intent.actionif (action=="com.idujing.play.notify.play_state"){if (videoView.isPlaying){videoView.pause()}else{videoView.resume()}}else if (action=="com.idujing.play.notify.next"){(mFragList.get(currentPage) as DetailOneFrag).nextData()}else if (action=="com.idujing.play.notify.prev"){(mFragList.get(currentPage) as DetailOneFrag).lastData()}else if (action=="seek"){val pos = intent.getLongExtra("pos", 0)videoView.seekTo(pos)}}}}val  intentFilter = IntentFilter()intentFilter.addAction(NotifyBuilderManager.ACTION_PLAY_PAUSE)intentFilter.addAction(NotifyBuilderManager.ACTION_NEXT)intentFilter.addAction(NotifyBuilderManager.ACTION_PREV)intentFilter.addAction("seek")registerReceiver(musicBroadcastReceiver,intentFilter, RECEIVER_EXPORTED)if("有通知权限和数据加载完成"){startMusicService()}}   /*** 常驻监听*/private fun  startMusicService() {mIntent = Intent(this, MusicService::class.java)bindService(mIntent!!, conn, Context.BIND_AUTO_CREATE);}private var mIntent: Intent? = nullprivate var msgService : MusicService? = nullprivate var conn: ServiceConnection = object : ServiceConnection {override fun onServiceDisconnected(name: ComponentName) {}override fun onServiceConnected(name: ComponentName, service: IBinder) {//返回一个MsgService对象msgService = (service as MsgBinder).service}}//仅演示
private fun addListener(){//播放器监听videoView.addOnStateChangeListener(object : BaseVideoView.OnStateChangeListener {override fun onPlayerStateChanged(playerState: Int) {}override fun onPlayStateChanged(playState: Int) {when(playState){BaseVideoView.STATE_PLAYING->{if(!isPlayIng){isPlayIng = trueif (null!=mIntent){msgService!!.updateData(this@FormationDetailOneActivity.javaClass.name,videoView.isPlaying,Constants.IMAGE_URL+imagePath,mCurrentData!!.detailName,resourceName,videoView.duration,videoView.currentPosition)}}}BaseVideoView.STATE_BUFFERED->{if (null!=mIntent){msgService!!.updateData(this@FormationDetailOneActivity.javaClass.name,videoView.isPlaying,Constants.IMAGE_URL+imagePath,mCurrentData!!.detailName,resourceName,videoView.duration,videoView.currentPosition)}}BaseVideoView.STATE_PAUSED->{isPlayIng = falseif (null!=mIntent){msgService!!.updateData(this@FormationDetailOneActivity.javaClass.name,videoView.isPlaying,Constants.IMAGE_URL+imagePath,mCurrentData!!.detailName,resourceName,videoView.duration,videoView.currentPosition)}}BaseVideoView.STATE_PLAYBACK_COMPLETED->{isPlayIng = falseif (null!=mIntent){msgService!!.updateData(this@FormationDetailOneActivity.javaClass.name,videoView.isPlaying,Constants.IMAGE_URL+imagePath,mCurrentData!!.detailName,resourceName,videoView.duration,videoView.currentPosition)}}}}})}override fun onDestroy() {super.onDestroy()if (null!=mIntent){stopService(mIntent)}unregisterReceiver(musicBroadcastReceiver)}}

3.需要的权限及注册Service

  <uses-permission android:name="android.permission.INTERNET"/><uses-permission android:name="android.permission.POST_NOTIFICATIONS"/><uses-permission android:name="android.permission.FOREGROUND_SERVICE"/><uses-permission android:name="android.permission.FOREGROUND_SERVICE_MEDIA_PLAYBACK"/><service android:name="com.anssy.bookvideo.utils.music.MusicService"android:foregroundServiceType="mediaPlayback"/>

4.效果
