I have written a program which is used to add the data to the firestore. On successful operation the current activity will redirect to another activity showing successful message. But if the operation fail or the internet is down for more than 10 seconds it should go to another activity showing error message. But the above program keep on waiting for the internet and doesn't redirect to error message. So is there any way that I can show redirect to error page if there's no internet or some other error occur. Here's my code:

What I have tried:

Toast.makeText(getBaseContext(),"Please wait while your submission is being sent",Toast.LENGTH_LONG).show();
mfirestore.collection("MYPrince").add(usmap).addOnSuccessListener(new OnSuccessListener<DocumentReference>() {
        @Override
        public void onSuccess(DocumentReference documentReference) {
            Intent i = new Intent(Thanks.this, success.class);
            startActivity(i);
        }
    }).addOnFailureListener(new OnFailureListener() {
        @Override
        public void onFailure(@NonNull Exception e) {
            Intent i = new Intent(Thanks.this, error.class);
            startActivity(i);
        }
    });
