implementation 'com.google.firebase:firebase-storage:15.0.0'
implementation 'com.google.firebase:firebase-auth:15.0.0'

and this code for uploading and getting a download link

private void uploadImageToFirebase(Bitmap bmp) {

    try {
        String file_path = Environment.getExternalStorageDirectory().getAbsolutePath() +
                "/news";
        File dir = new File(file_path);
        if (!dir.exists())
            dir.mkdirs();
        File file = new File(dir, "sketchpad" + "_" + ".png");
        FileOutputStream fOut = new FileOutputStream(file);
        bmp.compress(Bitmap.CompressFormat.PNG, 100, fOut);
        fOut.flush();
        fOut.close();
        Log.i("SECONDACTIVITY", "ADDED SUCCESSFULLY");

        Uri file2 = Uri.fromFile(file);


        //Now Upload
        final StorageReference storageRef = FirebaseStorage.getInstance().getReference();
        StorageReference riversRef = storageRef.child(file.getName());
        UploadTask uploadTask;
        uploadTask = riversRef.putFile(file2);
        progressDialog.show();
        progressDialog.setCancelable(false);


        uploadTask.addOnProgressListener(new OnProgressListener() {
            @Override
            public void onProgress(UploadTask.TaskSnapshot taskSnapshot) {
                double progress = (100.0 * taskSnapshot.getBytesTransferred()) / taskSnapshot.getTotalByteCount();
                progressDialog.incrementProgressBy((int) progress);
            }
        });
        uploadTask.addOnSuccessListener(new OnSuccessListener() {
            @Override
            public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
                progressDialog.dismiss();
                Uri DownloadLink = taskSnapshot.getDownloadUrl();
                String imgUrl = DownloadLink.toString();
                FirebaseDatabase.getInstance().getReference().child("image_link").setValue(imgUrl);
            }
        });
        uploadTask.addOnFailureListener(new OnFailureListener() {
            @Override
            public void onFailure(@NonNull Exception e) {
                progressDialog.dismiss();
            }
        });


    } catch (IOException e) {
        e.printStackTrace();
    }
