So I have this issue where every time I add a new user account, it kicks out the current user that is already signed in. I read the firebase api and it said that \"I

Android solution (Kotlin):

1.You need FirebaseOptions BUILDER(!) for setting api key, db url, etc., and don't forget to call build() at the end

2.Make a secondary auth variable by calling FirebaseApp.initializeApp()

3.Get instance of FirebaseAuth by passing your newly created secondary auth, and do whatever you want (e.g. createUser)

    // 1. you can find these in your project settings under general tab
    val firebaseOptionsBuilder = FirebaseOptions.Builder()
    firebaseOptionsBuilder.setApiKey("YOUR_API_KEY")
    firebaseOptionsBuilder.setDatabaseUrl("YOUR_DATABASE_URL")
    firebaseOptionsBuilder.setProjectId("YOUR_PROJECT_ID")
    firebaseOptionsBuilder.setApplicationId("YOUR_APPLICATION_ID") //not sure if this one is needed
    val firebaseOptions = firebaseOptionsBuilder.build()

    // indeterminate progress dialog *ANKO*
    val progressDialog = indeterminateProgressDialog(resources.getString(R.string.progressDialog_message_registering))
    progressDialog.show()

    // 2. second auth created by passing the context, firebase options and a string for secondary db name
    val newAuth = FirebaseApp.initializeApp(this@ListActivity, firebaseOptions, Constants.secondary_db_auth)
    // 3. calling the create method on our newly created auth, passed in getInstance
    FirebaseAuth.getInstance(newAuth).createUserWithEmailAndPassword(email!!, password!!)
    .addOnCompleteListener { it ->

        if (it.isSuccessful) {

            // 'it' is a Task, so we can get our newly created user from result
            val newUser = it.result.user

            // store wanted values on your user model, e.g. email, name, phonenumber, etc.
            val user = User()
            user.email = email
            user.name = name
            user.created = Date().time
            user.active = true
            user.phone = phone

            // set user model on /db_root/users/uid_of_created_user/, or wherever you want depending on your structure
            FirebaseDatabase.getInstance().reference.child(Constants.db_users).child(newUser.uid).setValue(user)

            // send newly created user email verification link
            newUser.sendEmailVerification()

            progressDialog.dismiss()

            // sign him out
            FirebaseAuth.getInstance(newAuth).signOut()
            // DELETE SECONDARY AUTH! thanks, Jimmy :D
            newAuth.delete()

        } else {

            progressDialog.dismiss()

            try {

                throw it.exception!!

                // catch exception for already existing user (e-mail)
            } catch (e: FirebaseAuthUserCollisionException) {

                alert(resources.getString(R.string.exception_FirebaseAuthUserCollision), resources.getString(R.string.alertDialog_title_error)) {

                    okButton {

                        isCancelable = false

                    }

                }.show()

            }

        }

    }
