在媒体播放器中，搜索栏不会随着android studio中的播放媒体而进展

Question

我一直在研究媒体播放器并尝试集成搜索栏，我使用Bind服务来编码MediaPlayer函数，并使用该绑定服务的引用在我的Activity中调用这些函数，我使用了Handler来协助runnable，但是，我的seekBar无法跟踪播放媒体的进度。

跟踪SeekBar的代码如下： -

Runnable runnable=new Runnable() {
    @Override
    public void run() {
seekUpdate();
    }
};
public void seekUpdate(){
    seekBar.setProgress(service.currentPosition());
    handler.postDelayed(runnable,1000);
}
    @Override
    public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
        service.seekTo(progress);


    }

    @Override
    public void onStartTrackingTouch(SeekBar seekBar) {

    }

    @Override
    public void onStopTrackingTouch(SeekBar seekBar) {

    }

我的Bind服务类中的代码（已集成MediaPlayer功能的地方）如下： -

package com.daman.mediaplayer;

import android.app.Service;
import android.content.Intent;
import android.media.MediaPlayer;
import android.os.Binder;
import android.os.IBinder;
import android.support.annotation.IntDef;

import java.io.IOException;

public class BindMusicService extends Service {
    String songToPlay,songPath;
    MediaPlayer mediaPlayer;
    IBinder ibRef = new MyBinder();
    PlayerActivity play;
    @Override
    public void onCreate() {
        super.onCreate();
    }

    @Override
    public int onStartCommand(Intent intent,int flags, int startId) {
        return super.onStartCommand(intent, flags, startId);
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
    }

    @Override
    public IBinder onBind(Intent intent) {
        // TODO: Return the communication channel to the service.
        mediaPlayer = new MediaPlayer();
        songToPlay = intent.getStringExtra("keySong");
        songPath=intent.getStringExtra("songpath");
        try {
            mediaPlayer.setDataSource(songPath);
            //mediaPlayer.setDataSource(this, Uri.parse(url));
        } catch (IOException e) {
            e.printStackTrace();
        }

        try {
            mediaPlayer.prepare();
        } catch (IOException e) {
            e.printStackTrace();
        }

        return ibRef;
    }

    @Override
    public boolean onUnbind(Intent intent) {

        return super.onUnbind(intent);
    }
    public void playMusic(){
        mediaPlayer.start();

    }

    public void pauseMusic(){
        mediaPlayer.pause();
    }

    public void stopMusic(){
        mediaPlayer.stop();
        mediaPlayer.release();
    }
    public int currentPosition(){
       return mediaPlayer.getCurrentPosition();
    }
    public int getDuration(){
       return mediaPlayer.getDuration();
    }
    public  void seekTo(int position){
        mediaPlayer.seekTo(position);
    }
    class MyBinder extends Binder{
        BindMusicService getServiceReference(){

                return BindMusicService.this;
        }
    }
}

当我播放并暂停媒体时，android监视器中弹出的错误是： -
