I'm new to FireStore, and when I was trying to insert a data using Hashmap it is showing error.
This is the line which I'm adding to my firestore:
Map map = new HashMap<>();
map.put("And","What");
map.put("So","What Bro");
firebaseFirestore.collection("mycollection").document("mydocument").set(map).addOnSuccessListener(new OnSuccessListener<Void>() {
@Override
public void onSuccess(Void aVoid) {
Toast.makeText(ContactActivity.this, "Success", Toast.LENGTH_SHORT).show();
}
}).addOnFailureListener(new OnFailureListener() {
@Override
public void onFailure(@NonNull Exception e) {
Toast.makeText(ContactActivity.this, "Failure", Toast.LENGTH_SHORT).show();
}
});
And the error is:
