Image Upload in Firestore Storage[Edit] The Question is how to use Storage of FireStore and not of Firebase. It get mistunderstood

Question

How to upload image in Firestore Storage from Android app and then save Download Url in Firestore database in Android? This is my code on which I was working. It looks like saving Image into Firestore is different from saving into Firebase. Kindly advise were I am doing wrong? Thanks in advance for your suggestion and help.

@Tejas Googled it up and only got how to upload in Firebase. While doing that got stuck on getting download URLand then realize that I am on wrong path and hence post the question — Sukesh Saxena, Oct 12 '18 at 05:09
you need to try first. then post your code with where you're stuck — Tejas Pandya, Oct 12 '18 at 05:11
@Doug the answer you are suggesting is for saving images in Firebase while my query is for Firestore. So it shall not be a duplicate question. Let me know if my understanding is wrong. — Sukesh Saxena, Oct 12 '18 at 07:18

I would do something like this:

private FirebaseDatabase firebaseDatabase;
private DatabaseReference databaseReference;

private FirebaseStorage firebaseStorage;
private StorageReference storageReference;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_add_to_database);

    firebaseDatabase = FirebaseDatabase.getInstance();
    databaseReference = firebaseDatabase.getReference();

    firebaseStorage = FirebaseStorage.getInstance();
    storageReference = firebaseStorage.getReference("my_upload_directory_name");

//In the putFile method, you get a TaskSnapshot which contains the details of your uploaded file
storageReference.putFile(imageUri).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
            @Override
            public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {

               //Upload URL we need to save to the database
                String uploadedImageUrl = taskSnapshot.getDownloadUrl().toString();

               //Now save the URL to the database
                 saveUploadUrlToFirebaseDatabase(uploadedImageUrl );
            }
        }).addOnFailureListener(new OnFailureListener() {
            @Override
            public void onFailure(@NonNull Exception e) {
              //Failed
            }
}

private void saveUploadUrlToFirebaseDtabase(String uploadedImageUrl ){
  databaseReference.child("your_root_name").setValue(uploadedImageUrl ).
  addSuccessListener(...).addFailureListener(...);
}
