if(requestCode== GALLERY_INTENT && resultCode== RESULT_OK)
    {
          mProgress.setMessage("Uploading....");
          mProgress.show();
          Uri uri =data.getData();
        StorageReference filepath = mStorage.child("Photos").child(uri.getLastPathSegment());
        filepath.putFile(uri).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
            @Override
            public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {

                mProgress.dismiss();
                Uri downloadUri = taskSnapshot.getDownloadUrl();

                Picasso.with(MainActivity.this).load(downloadUri).fit().centerCrop().into(mImageView);
                Toast.makeText(MainActivity.this,"Upload done",Toast.LENGTH_LONG).show();
            }
        }).addOnFailureListener(new OnFailureListener() {
            @Override
            public void onFailure(@NonNull Exception e) {
                Toast.makeText(MainActivity.this,"Upload  failed",Toast.LENGTH_LONG).show();
            }
        });
    }

I don't think there is an API to fetch all files stored in firebase storage. When i was saving files , i used to store the file metadata including the file name, download url etc in the real time database.

So when i had to fetch all the files from the storage, i would use the database.

Edit :

Here is how i did it.

UploadTask uploadTask = storageRef.putBytes(data,storageMetadata);
    uploadTask.addOnFailureListener(new OnFailureListener() {
        @Override
        public void onFailure(@NonNull Exception exception) {

        }
    }).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
        @Override
        public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
             //Save to database using
         //taskSnapshot.getMetadata().getCustomMetadata(StringKeys.SOME_KEY);
        }
    }).addOnProgressListener(new OnProgressListener<UploadTask.TaskSnapshot>() {
        @Override
        public void onProgress(UploadTask.TaskSnapshot taskSnapshot) {

        }
    });
