6. Add a String variable art, a Map variable map, and a ListMap musicListMap.

7. Add following imports:


import android.provider.MediaStore;
import android.net.Uri;
import android.database.Cursor;
import android.content.ContentResolver;
import android.content.pm.PackageManager;
import android.Manifest;

8. Create a more block readAllMusicFiles and put codes given below. After codes, use block to display musicListMap in listview1.


Uri uri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;

String[] projection = {
        MediaStore.Audio.Media._ID,
        MediaStore.Audio.Media.TITLE,
        MediaStore.Audio.Media.ARTIST,
        MediaStore.Audio.Media.ALBUM,
        MediaStore.Audio.Media.DURATION,
        MediaStore.Audio.Media.DATA,
        MediaStore.Audio.Media.ALBUM_ID
};


Cursor cursor = getContentResolver().query(
        uri,
        projection,
        MediaStore.Audio.Media.IS_MUSIC + "!= 0",
        null,
        MediaStore.Audio.Media.TITLE + " ASC"
);

if (cursor != null) {
    while (cursor.moveToNext()) {
        String title = cursor.getString(1);
        String artist = cursor.getString(2);
        String album = cursor.getString(3);
        long duration = cursor.getLong(4);
        String path = cursor.getString(5);
        long albumId = cursor.getLong(6);
        Uri albumArtUri = Uri.parse("content://media/external/audio/albumart/" + albumId);
        
        int totalSeconds = (int) (duration / 1000);
        int minutes = totalSeconds / 60;
        int seconds = totalSeconds % 60;
        String formatted_duration = String.format(Locale.getDefault(), "%02d:%02d", minutes, seconds);

        map = new HashMap<>();
        map.put("title", title);
        map.put("artist", artist);
        map.put("album", album);
        map.put("duration", formatted_duration);
        map.put("path", path);
        
        boolean hasAlbumArt = false;
        try (InputStream is =
         getContentResolver().openInputStream(albumArtUri)) {
             if (is != null) {
                 hasAlbumArt = true;
             }
        } catch (Exception e) {
            hasAlbumArt = false;
        }
        
        if (hasAlbumArt){
            map.put("albumArt", albumArtUri.toString());
        } else {
            map.put("albumArt", "");
        }

        musicListMap.add(map);
    }
    cursor.close();
}

9. Create another more block request_permissions and put following codes in it.


if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.TIRAMISU) {
    if (checkSelfPermission(Manifest.permission.READ_MEDIA_AUDIO)
            != PackageManager.PERMISSION_GRANTED) {

        requestPermissions(
                new String[]{Manifest.permission.READ_MEDIA_AUDIO},
                1001
        );
    }
} else {
    if (checkSelfPermission(Manifest.permission.READ_EXTERNAL_STORAGE)
            != PackageManager.PERMISSION_GRANTED) {

        requestPermissions(
                new String[]{Manifest.permission.READ_EXTERNAL_STORAGE},
                1001
        );
    }
}

}

@Override
public void onRequestPermissionsResult(int _requestCode, String[] permissions, int[] grantResults) {
    super.onRequestPermissionsResult(_requestCode, permissions, grantResults);
    if (_requestCode == 1001) {
        _readAllMusicFiles();
    }

10. In onCreate, use blocks request_permissions and readAllMusicFiles.

11. In onBindCustomView, use blocks as shown below.


12. Save and run the project.
