Trying to implement Facebook Login using Firebase on Android Studio. Screen is stuck loading facebook login page when i try to sign in

i'm a beginner who is learning how to use Android studio and this is my first time posting on Stack Overflow. I wish to implement Facebook login on my android app. I mostly followed this tutorial (https://www.youtube.com/watch?v=ImbuK35vmzs&t=1540s) to create the sign in using facebook.
While I'm able to run the app, ,whenever i click on the sign in using facebook button, the chrome browser opens up and the screen is stuck loading the facebook sign in page (refer to the screenshot). No error pops up on logcat, i've already enabled internet permission in the android manifest file as well as check to see the facebook access id + secret key were correctly copied. Below is my MainActivity.java code. Any idea why this issue might be happening and how do i go about troubleshooting it? Thank you.

Hi i am having a problem with my the google connexion. Every time that the code is executed it goes in to the catch. I dont know why. I followed the steps from the Google tutorial and saw manyq questions related to that on stack but still not help me to solve this issue. Whe the code is runned it goes in to the catch and it shows the toast that i made. " error while .. ".
Here is what it looks like. I am posting the whole code for the authentification so everyone can analyze it and give me a solution if possible .

I think you didn't instanciate the GoogleApiClient object..
try this code .. it worked for me ..
//a constant for detecting the login intent result
private static final int RC_SIGN_IN = 234;
//Tag for the logs optional
private static final String TAG = "YoussefIslem";
//creating a GoogleSignInClient object
GoogleSignInClient mGoogleSignInClient;
GoogleApiClient googleApiClient;
CallbackManager mCallbackManager;

super.onCreate(savedInstanceState);

.requestIdToken(getString(R.string.web_client_id))
.requestEmail()
.build();
googleApiClient =new GoogleApiClient.Builder(this)
.enableAutoManage(this,this)
.addApi(Auth.GOOGLE_SIGN_IN_API,gso)
.build();
//Then we will get the GoogleSignInClient object from GoogleSignIn class
mGoogleSignInClient = GoogleSignIn.getClient(this, gso);
findViewById(R.id.googleContinue).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
signIn();
}
});
}
private void firebaseAuthWithGoogle(GoogleSignInAccount acct) {
Log.d(TAG, "firebaseAuthWithGoogle:" + acct.getId());
//getting the auth credential
AuthCredential credential = GoogleAuthProvider.getCredential(acct.getIdToken(), null);
//Now using firebase we are signing in the user here
mAuth.signInWithCredential(credential)
.addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
#Override
public void onComplete(#NonNull Task<AuthResult> task) {
if (task.isSuccessful()) {
Log.d(TAG, "signInWithCredential:success");
FirebaseUser user = mAuth.getCurrentUser();
Toast.makeText(MainActivity.this, "User Signed In", Toast.LENGTH_SHORT).show();
Intent intent = new Intent(MainActivity.this, HomeActivity.class);
startActivity(intent);
finish();
} else {
// If sign in fails, display a message to the user.
Log.w(TAG, "signInWithCredential:failure", task.getException());

How to add a cancel button for google signIn accountPicker dialog box in android

I am new to android. I am trying to make an android application with authentication by google signIn using firebase. I want to add an additional button to the google signIn accountPicker. This is my code:
public class MainActivity extends AppCompatActivity {
private static final String TAG = "MainActivity";
GoogleSignInClient mGoogleSignInClient;
private int RC_SIGN_IN = 1;
private FirebaseAuth mAuth;
android.app.AlertDialog Dialog;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mAuth = FirebaseAuth.getInstance();
// Configure sign-in to request the user's ID, email address, and basic
// profile. ID and basic profile are included in DEFAULT_SIGN_IN.
// Configure Google Sign In
GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
.requestIdToken(getString(R.string.default_web_client_id))
.requestEmail()
.build();
// Build a GoogleSignInClient with the options specified by gso.
mGoogleSignInClient = GoogleSignIn.getClient(MainActivity.this, gso);
signIn();
}
private void signIn() {
Intent signInIntent = mGoogleSignInClient.getSignInIntent();
startActivityForResult(signInIntent, RC_SIGN_IN);
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
// Result returned from launching the Intent from GoogleSignInApi.getSignInIntent(...);
if (requestCode == RC_SIGN_IN) {
Task<GoogleSignInAccount> task = GoogleSignIn.getSignedInAccountFromIntent(data);
try {
// Google Sign In was successful, authenticate with Firebase
GoogleSignInAccount account = task.getResult(ApiException.class);
firebaseAuthWithGoogle(account);
} catch (ApiException e) {
// Google Sign In failed, update UI appropriately
Log.w(TAG, "Google sign in failed", e);
// ...
}
}
}
private void firebaseAuthWithGoogle(GoogleSignInAccount acct) {
Log.d(TAG, "firebaseAuthWithGoogle:" + acct.getId());
AuthCredential credential = GoogleAuthProvider.getCredential(acct.getIdToken(), null);
mAuth.signInWithCredential(credential)
.addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
#Override
public void onComplete(#NonNull Task<AuthResult> task) {
if (task.isSuccessful()) {
// Sign in success, update UI with the signed-in user's information
Log.d(TAG, "signInWithCredential:success");
FirebaseUser user = mAuth.getCurrentUser();
updateUI(user);
} else {
// If sign in fails, display a message to the user.
Log.w(TAG, "signInWithCredential:failure", task.getException());
Toast.makeText(getApplicationContext() , "Authentication failed" , Toast.LENGTH_SHORT).show();
updateUI(null);
}
// ...
}
});
}
private void updateUI(FirebaseUser user) {
GoogleSignInAccount acct = GoogleSignIn.getLastSignedInAccount(getApplicationContext());
if (acct != null) {
String personName = acct.getDisplayName();
String personGivenName = acct.getGivenName();
String personFamilyName = acct.getFamilyName();
String personEmail = acct.getEmail();
String personId = acct.getId();
Uri personPhoto = acct.getPhotoUrl();
Toast.makeText(getApplicationContext() , "Name = "+ personName , Toast.LENGTH_SHORT).show();
}
}
}
Here is the accountpicker dialog of the google signIn.
I need to add an additional (Cancel)button in this dialog.
Is there a way to do this?

This unique id SiQEIDaQJfUBqZBBt1eo is generated when you are adding the user as a Map or when you are using a call to document() method without passing an argument.
In order to solve this, there are two ways. One would be to create a model class (UserModel), then create an object of that class and in the end get the uid of the user once it authenticated and add the object to the database like this:
String Name = textInputEditTextName.getText().toString().trim();
String Email = textInputEditTextEmail.getText().toString().trim();
String Password = textInputEditTextPassword.getText().toString().trim();
String Phone_Number = textInputEditTextPhone.getText().toString().trim();
String ConfirmPassword = textInputEditTextConfirmPassword.getText().toString().trim();
UserModel userModel = new UserModel(Name, Email, Password, Phone_Number, ConfirmPassword);
String uid = FirebaseAuth.getInstance().getCurrentUser().getUid();
FirebaseFirestore rootRef = FirebaseFirestore.getInstance();
CollectionReference usersRef = rootRef.collection("users");
usersRef.document(uid).set(userModel);
See, I have passed the uid as argument to the document() method.
The second approach would be to pass no argument to the document() method but to store that key into a variable like this:
String key = usersRef.document().getKey();
usersRef.document(key).set(userModel);
Edit:
There also another method, which I recommend you use it. Instead of using this line of code:
mFirebaseFirestore.collection("users")
.add(user)
.addOnSuccessListener(/* ... */)
Use the following line of code:
mFirebaseFirestore.collection("users")
.document(uid)
.set(user)
.addOnSuccessListener(/* ... */)
Remove the old data, add fresh one and your problem will be solved.
