Password length through Firebase authentication

How do I make an error message on password length? through Firebase Authentication for login. If final EditText mpassword.mpassword.setError("Password Must be Between 8 and 15 Characters.");
return;
I have tried to make an if/else statement out of the password length, but that didn't even seem to work right.
Here is the code I have so far.

import android.content.Intent;
import android.os.Bundle;

import androidx.appcompat.app.AppCompatActivity;

public class LoginActivity extends AppCompatActivity {
protected void onCreate(Bundle savedInstanceState, ClassNotFoundException task) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_sign_up);
Button login;
Button sign_up;
final EditText mail;
final EditText mpassword;
TextView forgotpassword;
final FirebaseAuth auth;
auth = FirebaseAuth.getInstance();
mail = findViewById(R.id.username);
mpassword = findViewById(R.id.Password);
login = findViewById(R.id.login);
sign_up = findViewById(R.id.signup);
forgotpassword = findViewById(R.id.forgotpassword);
login.setOnClickListener((new View.OnClickListener() {
#Override
public void onClick(View v) {
finish();
}
}));
sign_up.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String email_address = mail.getText().toString().trim();
String password = mpassword.getText().toString().trim();
if (TextUtils.isEmpty(email_address)) {
mail.setError("Email is Required.");
return;
}
if (TextUtils.isEmpty(password)) {
mpassword.setError("Password Required.");
return;
if (!(password.length() < 8 && (password.length() > 15))) {
final EditText mpassword.mpassword.setError("Password Must be Between 8 and 15 Characters.");
return;
}
auth.signInWithEmailAndPassword(email_address, password).addOnCompleteListener(new OnCompleteListener<AuthResult>() {
#Override
public void onComplete(#NonNull Task<AuthResult> task) {
if (task.isSuccessful())
startActivity(new Intent(getApplicationContext(), MainActivity.class) {
});
else {
Toast.makeText(LoginActivity.this, "Error!" + task.getException().getMessage(), Toast.LENGTH_SHORT).show();
startActivity(new Intent(getApplicationContext(), MainActivity.class));
}
};
});
};
};
});
};
};

You need a logical OR with || instead of a logical AND with &&:
if (!(password.length() < 8 || (password.length() > 15)))
This will evaluate to true if the password length if less than 8 OR greater than 15.

Replace AND with OR , then remove ! . That should do it.
if ((password.length() < 8 || (password.length() > 15))) {

Firebase User == null all the time

My app uses firebase and it needs to send a verification email to the user after registration before they can login. In my code, the app fails to send the verification email and I found out that the user is always null (while debugging) in line 86/88 of my code. any help would be greaty appreciated.
I've tried retracing my steps back but I couldn't get where i nicked an artery

Thanks a lot #Praveen and #Alex... figured it out, I made a mistake of signing out the user in the else statement [of the if(user.isEmailVerified()) block in the firebaseAuthSetup() method]. probably wouldn't have gotten it if I didn't retrace from the onComplete()

Code jump to the error statement insist of the creating the account in registration app

I am trying to create a registration Activity in my android application when I compile it runs without and error it seems like there is a logical problem when I run my application instant of creating a new account it jumps to the error code as I have provided my registration activity code in the in method creatnewAccount() in the if statement where I have tried to check whether the rpassword and the password are same. Whenever I run my application and enter the detail and click signup button it jumps to the else statement. Can't understand what's the error and what should I do

Replace this

with this
if (rpassword.equals(password) ){

when I'm using this code and signing in with a phone number for the second it should actually prompt "this number already exists" but it isn't working and upon signing in with the same number again all the older names and passwords are being replaced by new ones....how can I solve this issue???

try to remove your intent flow ;-
Intent intent= new Intent(RegisterActivity.this, MainActivity.class);
startActivity(intent);

Firebase Email and password Authentication fails mAuth.signInWithEmailAndPassword(email, password).addOnCompleteListener((task)

This is my CustomerLoginRegisterActivity.java that gets customer's Email and password for login and registers email and password to firebase if they don't have an account,

But The Firebase authentication fails everytime during registration.
I've enabled Sign-In method in my Firebase Account
