My application is crashing and giving error 'mAuth = FirebaseAuth.getInstance();'
in onCreate
method.
I tried different version of dependencies but facing same problem.
public class MainActivity extends AppCompatActivity{
private FirebaseAuth mAuth;
private Button buttonLogin;
private EditText editTextEmail;
private EditText editTextPass;
private ProgressDialog progressDialog;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Initialize Firebase Auth
''' mAuth = FirebaseAuth.getInstance();
editTextEmail = findViewById(R.id.editText_username);
editTextPass = findViewById(R.id.editText2_password);
buttonLogin = findViewById(R.id.buttonLogin);
buttonLogin.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String email = editTextEmail.getText().toString().trim();
String password = editTextPass.getText().toString().trim();
mAuth.signInWithEmailAndPassword(email, password)
.addOnCompleteListener(MainActivity.this, new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
if (task.isSuccessful()) {
Toast.makeText(MainActivity.this, "Login Successfully", Toast.LENGTH_LONG).show();
} else {
Toast.makeText(MainActivity.this, "User not exist", Toast.LENGTH_LONG).show();
}
// ...
}
});
}
});
}
}

try this way :-
if your error is showing Initialize Firebase Auth then update your project level gradle file and update the google classpath:-
classpath 'com.google.gms:google-services:4.2.0'
mAuth = FirebaseAuth.getInstance();
if(mAuth.getCurrentUser() != null){
// user exist
}else{
//user not exist
}
