[FIXED] Collection not Created in Firebase Console

Issue

I have implemented a code to create a collection named "Users". the code is running properly but is not saving my data in the database of my console.

Here is my code

user_profile.putFile(imageUri).addOnCompleteListener(new OnCompleteListener<UploadTask.TaskSnapshot>() {
     @Override
     public void onComplete(@NonNull Task<UploadTask.TaskSnapshot> uploadtask) {
         String download_url = uploadtask.getResult().getDownloadUrl().toString();

         if (uploadtask.isSuccessful()){
             Map<String,Object> userMap = new HashMap<>();
             userMap.put("name",user);
             userMap.put("image",download_url);
             firebaseFirestore.collection("Users")
                              .document(user_id).set(userMap)
                              .addOnSuccessListener(new OnSuccessListener<Void>() {
                                   @Override
                                   public void onSuccess(Void aVoid) {
                                       Toast.makeText(RegistrationActivity.this, "Uploaded Successfully", Toast.LENGTH_SHORT).show();
                                       SendToMain();
                                       progressBar.setVisibility(View.INVISIBLE);
                                   }
                              });
          } else {
              Toast.makeText(RegistrationActivity.this, "error: "+uploadtask.getException().getMessage(), Toast.LENGTH_SHORT).show();

          }
      }
});

I don't know what's going wrong and what's causing the problem. please help me for this. I am new to firebase by the way.

Solution

sometimes It would be better to allow Firebase store to auto create meaningful documentID for you.

can you try using add() function like below.

    firebaseFirestore.collection("Users").add(UserMap)
    .addOnSuccessListener(new OnSuccessListener<DocumentReference>() {
        @Override
        public void onSuccess(DocumentReference documentReference) {
            Log.d(TAG, "DocumentSnapshot written with ID: " + documentReference.getId());
        }
    })
    .addOnFailureListener(new OnFailureListener() {
        @Override
        public void onFailure(@NonNull Exception e) {
            Log.w(TAG, "Error adding document", e);
        }
    });
