This image shows current output which is shuffled and duplicate

I have an arraylist mp3 file paths I want to extract thumbnails from them it is working fine with the First Code of Bitmap but extraction speed is too slow.

filterpath==path of MP3 files.

MEDIACOVER==Arraylist to store bitmap images.

Glide version==com.github.bumptech.glide:glide:4.8.0, I think this is the latest version of Glide.

public class Main2Activity extends AppCompatActivity {
private ArrayAdapter<Bitmap> adp;
ListView lv;
ArrayList<String> path;

@Override
protected void onCreate(Bundle savedInstanceState) 
 super.onCreate(savedInstanceState);
 setContentView(R.layout.activity_main2);
 path=new ArrayList<>();
 lv=findViewById(R.id.chckimage);
 Intent in=getIntent();
 path=in.getStringArrayListExtra("path");
 adp = new ArrayAdapter(Main2Activity.this, 
 android.R.layout.simple_list_item_1);
 lv.setAdapter(adp);
 loadArrayList(path);
 lv.setOnItemClickListener(new AdapterView.OnItemClickListener() 
 @Override
 public void onItemClick(AdapterView<?> parent, View view, int 
 position, long id) 
 ImageView iv=findViewById(R.id.getting);
 iv.setImageBitmap(adp.getItem(position));
 Toast.makeText(Main2Activity.this, ""+adp.getItem(position), 
 Toast.LENGTH_LONG).show();
 
 );
 

Now method to Load images.....

 public void loadArrayList(ArrayList<String> Path) 
 try 
 for(String temp:Path)
 MediaMetadataRetriever mmr = new MediaMetadataRetriever();
 mmr.setDataSource(temp);
 byte[] data = mmr.getEmbeddedPicture();
 if (data != null) 
 Glide.with(this)
 .asBitmap()
 .load(data)
 .thumbnail(0.1f)
 .apply(RequestOptions.circleCropTransform()) //------getting image in circle
 .listener(new RequestListener<Bitmap>() 
 @Override
 public boolean onLoadFailed(@Nullable GlideException e, Object model, Target<Bitmap> target, boolean isFirstResource) 
 return false;
 

 @Override
 public boolean onResourceReady(Bitmap resource, Object model, Target<Bitmap> target, DataSource dataSource, boolean isFirstResource) 
 adp.add(resource);
 return true;
 
 ).submit();
 mmr.release();
 else

 //LOAD FROM DRAWABLE
 

 
 catch (Exception e)
 

Here, I used imageview for checking, Now its give another errors like
duplicates values and also shufled from their paths

I want to get total images from total paths in arraylist

I am getting this outputs by running same app...and the size of path arraylist is only 5. But its give me output 10 bitmap images with duplicate of every value

Now i found a answer for my question and want to help others to not stuck in this same problem...

public class GlideBitmap extends AppCompatActivity 
MediaMetadataRetriever mmr;
byte[] data;
ArrayList<Bitmap> BMP;
ListView listView;
Bitmap bitmap;

@Override
protected void onCreate(Bundle savedInstanceState) 
 super.onCreate(savedInstanceState);
 setContentView(R.layout.activity_glide_bitmap);
 listView=findViewById(R.id.bitmap);
 BMP=new ArrayList<>();
 try 
 gettingData();
 catch (ExecutionException e) 
 e.printStackTrace();
 Toast.makeText(this, ""+e.toString(), Toast.LENGTH_SHORT).show();
 catch (InterruptedException e) 
 e.printStackTrace();
 Toast.makeText(this, ""+e.toString(), Toast.LENGTH_SHORT).show();
 
//Here Toast is used to check the size of arraylist that 
//is it equal to path list or not.
 int size=BMP.size();
 Toast.makeText(this, ""+size, Toast.LENGTH_SHORT).show();

Now let's see the Main method of this answer...

public ArrayList<Bitmap> gettingData() throws ExecutionException, InterruptedException 
 mmr=new MediaMetadataRetriever();
 for(String temp:MainActivity.path)
 mmr.setDataSource(temp);
 data=mmr.getEmbeddedPicture();

 if(data!=null)
 Glide.with(this)
 .asBitmap()
 .load(data)
 .listener(new RequestListener<Bitmap>() 
 @Override
 public boolean onLoadFailed(@Nullable GlideException e, Object model, Target<Bitmap> target, boolean isFirstResource) 
 return false;
 

 @Override
 public boolean onResourceReady(Bitmap resource, Object model, Target<Bitmap> target, DataSource dataSource, boolean isFirstResource) 
 bitmap=resource;
 return false;
 
 ).submit();
 BMP.add(bitmap);
 bitmap=null;

 else
 Glide.with(this)
 .asBitmap()
 .load(R.drawable.example_picture)
 .listener(new RequestListener<Bitmap>() 
 @Override
 public boolean onLoadFailed(@Nullable GlideException e, Object model, Target<Bitmap> target, boolean isFirstResource) 
 return false;
 

 @Override
 public boolean onResourceReady(Bitmap resource, Object model, Target<Bitmap> target, DataSource dataSource, boolean isFirstResource) 
 bitmap=resource;
 return false;
 
 ).submit();
 BMP.add(bitmap);
 bitmap=null;
 
 
 return BMP;
 

try change the method of glide from asynchronous into synchronous.

public ArrayList<Bitmap> getArrayList(ArrayList<String> Path) 
 try 
 arrayList=new ArrayList<>();
 for(String temp:Path)
 MediaMetadataRetriever mmr = new MediaMetadataRetriever();
 mmr.setDataSource(temp);
 byte[] data = mmr.getEmbeddedPicture();
 if (data != null) 
 FutureTarget<Bitmap> submit = Glide.with(this)
 .asBitmap()
 .load(data)
 .thumbnail(0.1f)
 .apply(RequestOptions.circleCropTransform()) //------getting image in circle
 .submit();
 button.setImageBitmap(submit.get());
 arrayList.add(submit.get());
 mmr.release();
 else
 Bitmap bitmap=BitmapFactory.decodeResource(this.getResources(),
 R.drawable.example_picture);
 arrayList.add(bitmap);
 mmr.release();
 

 
 catch (Exception e)
 
 return arrayList;
