从Android Emulator播放歌曲时的静态噪音

如何解决从Android Emulator播放歌曲时的静态噪音

我目前遇到一个问题，当我运行Android Studio时会产生静电噪声。当我导入SeekBar并开始为其输入代码时，就会发生这种情况。我曾尝试调试并安装新的Android Studio版本，但两者均无法正常工作。有人可以帮我吗？

这是我的playSongActivity代码：

    public class PlaySongActivity extends AppCompatActivity {
    private String songId = "";
    private String title = "";
    private String artist = "";
    private String fileLink = "";
    private String coverArt = "";
    private String url = "";
    private MediaPlayer player = null;
    private static final String BASE_URL = "https://p.scdn.co/mp3-preview/";
    private Button playPause = null;
    private int musicPosition = 0;
    TextView duration_played;
    ImageView shuffleBtn;
    ImageView repeatBtn;

    Boolean repeatFlag = false;
    Boolean shuffleFlag = false;

    public  SongCollection songCollection = new SongCollection();
    List<Song> shuffleList = Arrays.asList(songCollection.songs);

    SeekBar seekBar;
    Handler handler = new Handler();

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_play_song);
        duration_played = findViewById(R.id.duration_played);
        retrieveData();
        displaySong();


        repeatBtn = findViewById(R.id.btnRepeat);
        shuffleBtn = findViewById(R.id.shuffle_btn);
        playPause = findViewById(R.id.btnPlayPause);
        seekBar = findViewById(R.id.seekBar);
    }

    private void retrieveData() {
        
        Intent intent = getIntent();

        songId = intent.getStringExtra("id");
        title = intent.getStringExtra("title");
        artist = intent.getStringExtra("artiste");
        fileLink = intent.getStringExtra("fileLink");
        coverArt = intent.getStringExtra("coverArt");

        url = BASE_URL + fileLink;
    }

     private void displaySong() {
       
        TextView txtTitle = findViewById(R.id.tvSongTitle);
        txtTitle.setText(title);

        TextView txtArtiste = findViewById(R.id.tvArtist);
        txtArtiste.setText(artist);

        int imageId = AppUtil.getImageIdFromDrawable(this,coverArt);
