Firebase Signinwithemailandpassword And Createuserwithemailandpassword Not Working In Android

I'm developing Android application where I'm using Firebase Authentication for user login by giving email and password. I have used the basic tutorial provided by Firebase for it b

Solution 1:

do following changes in your code

declare AuthListener :

// [START declare_auth_listener]private FirebaseAuth.AuthStateListener mAuthListener;
    // [END declare_auth_listener]// [START declare_auth]private FirebaseAuth mAuth;
    // [END declare_auth]

add listner in onStart() and onStop():

@OverridepublicvoidonStart() {
    super.onStart();
    mAuth.addAuthStateListener(mAuthListener);
}

@OverridepublicvoidonStop() {
    super.onStop();
    if (mAuthListener != null) {
        mAuth.removeAuthStateListener(mAuthListener);
    }
}

then add AuthStateListner method in onCreate() of your Activity,It will check for Auth status every time your activity is created:

// [START auth_state_listener] ,this method execute as soon as there is a change in Auth status , such as user sign in or sign out.
        mAuthListener = newFirebaseAuth.AuthStateListener() {
            @OverridepublicvoidonAuthStateChanged(@NonNull FirebaseAuth firebaseAuth) {
                FirebaseUseruser= firebaseAuth.getCurrentUser();

                if (user != null) {   
                    // User is signed in        //redirect 
                  updateUI(user);

                } else {
                    // User is signed out
                    Log.d(TAG, "onAuthStateChanged:signed_out");
                  updateUI(null);
                }

            }
        };
 // [END auth_state_listener]

for Sign in with email password do this..

        private void signIn(String email, String password)
       {
    Log.d(TAG, "signIn:" + email);
    if (!validateForm())
    {
        return;
    }

    mAuth.signInWithEmailAndPassword(email, password).addOnCompleteListener(this, new OnCompleteListener<AuthResult>()
    {
        @Override
        public void onComplete(@NonNull Task<AuthResult> task)
        {
         Log.d(LOG_TAG, " Verification : signIn With Email:onComplete:" + task.isSuccessful());
                    //  If sign in succeeds i.e if task.isSuccessful(); returns true then the auth state listener will be notified and logic to handle the// signed in user can be handled in the listener.// If sign in fails, display a message to the user.
             if (!task.isSuccessful()) {
                        try {
                            throw task.getException();
                        } catch (FirebaseAuthInvalidUserException e) {
                            mStatusTextView.setError("Invalid Emaild Id");
                            mStatusTextView.requestFocus();
                        } catch (FirebaseAuthInvalidCredentialsException e) {
                            Log.d(LOG_TAG , "email :" + email);
                            mStatusTextView.setError("Invalid Password");
                            mStatusTextView.requestFocus();
                        } catch (FirebaseNetworkException e) {
                            showErrorToast("error_message_failed_sign_in_no_network");
                        } catch (Exception e) {
                            Log.e(LOG_TAG, e.getMessage());
                        }
                        Log.w(LOG_TAG, "signInWithEmail:failed", task.getException());
                        Toast.makeText(LoginActivity.this, R.string.login_error,
                                Toast.LENGTH_SHORT).show();
                        updateUI(null);
        }
    });

}
