Firebase stores the email and password.
I need to add username to registration.
I also need to authenticate (Login) Users with Username/Password NOT Email/Password.
Registration should have username, email and password...
While Login should be with username and password.
RegisterActivity.java
public class RegisterActivity extends AppCompatActivity {
private EditText inputEmail, inputPassword;
private Button btnSignUp;
private ProgressBar progressBar;
private FirebaseAuth auth;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_register);
auth = FirebaseAuth.getInstance();
btnSignUp = (Button) findViewById(R.id.sign_up_button);
inputEmail = (EditText) findViewById(R.id.email);
inputPassword = (EditText) findViewById(R.id.password);
progressBar = (ProgressBar) findViewById(R.id.progressBar);
btnSignUp.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String email = inputEmail.getText().toString().trim();
String password = inputPassword.getText().toString().trim();
if (TextUtils.isEmpty(email)) {
Toast.makeText(getApplicationContext(), "Enter email address!", Toast.LENGTH_SHORT).show();
return;
}
if (TextUtils.isEmpty(password)) {
Toast.makeText(getApplicationContext(), "Enter password!", Toast.LENGTH_SHORT).show();
return;
}
if (password.length() < 6) {
Toast.makeText(getApplicationContext(), "Password too short, enter minimum 6 characters!", Toast.LENGTH_SHORT).show();
return;
}
progressBar.setVisibility(View.VISIBLE);
//create user
auth.createUserWithEmailAndPassword(email, password)
.addOnCompleteListener(RegisterActivity.this, new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
progressBar.setVisibility(View.GONE);
// If sign in fails, display a message to the user. If sign in succeeds
// the auth state listener will be notified and logic to handle the
// signed in user can be handled in the listener.
if (!task.isSuccessful()) {
Toast.makeText(RegisterActivity.this, "Authentication failed." + task.getException(),
Toast.LENGTH_SHORT).show();
} else {
startActivity(new Intent(RegisterActivity.this, WelcomeActivity.class));
finish();
}
}
});
}
});
}
@Override
protected void onResume() {
super.onResume();
progressBar.setVisibility(View.GONE);
}
}
LoginActivity.java
public class LoginActivity extends AppCompatActivity {

//startActivity(new Intent(LoginActivity.this, ResetPasswordActivity.class));
}
});

if (TextUtils.isEmpty(password)) {

}
progressBar.setVisibility(View.VISIBLE);
//authenticate user

progressBar.setVisibility(View.GONE);
if (!task.isSuccessful()) {
// there was an error
if (password.length() < 6) {
inputPassword.setError(getString(R.string.minimum_password));
} else {
Toast.makeText(LoginActivity.this, getString(R.string.auth_failed), Toast.LENGTH_LONG).show();
}
} else {
Intent intent = new Intent(LoginActivity.this, WelcomeActivity.class);
startActivity(intent);
finish();
}
}
});
}
});
}
