Firebase Realtime Databae Not Working, Setvalue

I made sample by tutorial 'https://firebase.google.com/docs/database/android/start/?hl=ko' for Firebase realtime database But I cannot see any data after onDataChanged 'EventValue

Solution 1:

this example will insert new user data in firebase db.

 FirebaseDatabase database;
    DatabaseReference usersTable;
    database = FirebaseDatabase.getInstance();
    usersTable = database.getReference("Users");
    /*we work here */
    usersTable.addValueEventListener(newValueEventListener() {
                    @OverridepublicvoidonDataChange(DataSnapshot dataSnapshot) {

                        progressDialog.dismiss();
                        if (dataSnapshot.child(phoneEditText.getText().toString()).exists()) {

                            Toast.makeText(SignUp.this, "Number already register", Toast.LENGTH_SHORT).show();
                        }else{
                            Usersusers=newUsers(nameEditText.getText().toString(),passwordEditTex.getText().toString(),phoneEditText.getText().toString());
                            usersTable.child(phoneEditText.getText().toString()).setValue(users);
                            Toast.makeText(SignUp.this, "Signup Sucessfully", Toast.LENGTH_SHORT).show();
                            finish();
                        }


                    }

                    @OverridepublicvoidonCancelled(DatabaseError databaseError) {

                    }
                });

hope this will help you
