Как сделать GetCredential () работать на Java? ⇐ Android

[Anonymous]

Я нахожусь в процессе добавления номера телефона и входа в учетную запись Google в мое приложение. (Я даже пытался спросить CHATGPT и Gemini, не помог )
в основном, в каждом способе, когда я пробовал, в итоге не удалось, потому что компилятор не распознает методы в учетных записях (я использую правильный, новый, версия Androidx Imported Class). Фрагмент. Соответствующий код:
in oncreateview ():

Код: Выделить всё

        //instance the mAuth as an instance of FirebaseAuth:
mAuth = FirebaseAuth.getInstance();
//instance the CredentialManager:
credentialManager = CredentialManager.create(requireContext());

googleSignInButton.setOnClickListener(v -> {

//start the sign-in process:
if(isAdded()){
getGoogleCredentialTask(requireContext())
.addOnSuccessListener(response -> {
Credential credential = response.getCredential();
signInWithGoogleId(credential);
})
.addOnFailureListener(e -> {
Log.e(TAG, "Google sign-in failed" + e);
Toast.makeText(getContext(), "Google sign-in failed: " + e, Toast.LENGTH_SHORT).show();
});
}
}

Outs OncreatView (), на уровне фрагмента:

    //the method handling and returning the appropriate Task for the googleID sign-in process:
private Task getGoogleCredentialTask(Context context) {
TaskCompletionSource taskCompletionSource = new TaskCompletionSource();

GetGoogleIdOption googleIdOption = new GetGoogleIdOption.Builder()
.setFilterByAuthorizedAccounts(false)
.setServerClientId(CLIENT_ID)
.build();

GetCredentialRequest request = new GetCredentialRequest.Builder()
.addCredentialOption(googleIdOption)
.build();

Executor executor = context != null ? ContextCompat.getMainExecutor(context) : Runnable::run;

--------**The error is right here!**---------------------------------------------------
credentialManager.getCredential(requireActivity(), request)
.addOnSuccessListener(executor, taskCompletionSource::setResult)
.addOnFailureListener(executor, taskCompletionSource::setException);
-----------------------------------------------------------------------------------

return taskCompletionSource.getTask();
}

//the method to initiate google sign-in with the given GoogleID credential:
private void signInWithGoogleId(Credential credential){
//make sure the given credential is a GoogleID credential:
if(credential instanceof CustomCredential && credential.getType().equals(TYPE_GOOGLE_ID_TOKEN_CREDENTIAL)){
//create GoogleID token from the credential:
CustomCredential customCredential = (CustomCredential) credential;
Bundle bundle = customCredential.getData();
GoogleIdTokenCredential googleIdTokenCredential = GoogleIdTokenCredential.createFrom(bundle);

//authorize with firebase: with a method.
authorizeWithFirebaseGoogle(googleIdTokenCredential.getIdToken());

} else{
Toast.makeText(getContext(), "Credential type is not of GoogleID!", Toast.LENGTH_SHORT).show();
}

}

//the method to authorize with firebase with a GoogleID token (final step):
private void authorizeWithFirebaseGoogle(String idToken){
AuthCredential authCredential = GoogleAuthProvider.getCredential(idToken, null);
mAuth.signInWithCredential(authCredential).addOnCompleteListener(requireActivity(), new OnCompleteListener() {
@Override
public void onComplete(@NonNull Task task) {
handleSignInResult(task);
}
});
}

//as i said, this isn't only for the google sign-in.  This method works great.
//handle the sign-in result from the googleID sign-in and phone number sign-in:
private void handleSignInResult(Task task){
if(task.isSuccessful()){
//great! the user has been approved and the sign in was successful.
Toast.makeText(getContext(), "Signed-in successfully! P", Toast.LENGTH_SHORT).show();
//insert the user:
firebaseUser = task.getResult().getUser();
//Done!
} else{
//the sign-in has not been approved.
Toast.makeText(getContext(), "Sign-in failed.", Toast.LENGTH_SHORT).show();
if (task.getException() instanceof FirebaseAuthInvalidCredentialsException) {
// The verification code entered was invalid:
Toast.makeText(getContext(), "The verification code is wrong. Try again.", Toast.LENGTH_SHORT).show();
} else{
Toast.makeText(getContext(), "Other Error.", Toast.LENGTH_SHORT).show();
}
}
}

Сама ошибка: < /p>
Cannot resolve method 'getCredential(FragmentActivity, GetCredentialRequest)'

Candidates for method call credentialManager. getCredential(requireActivity(), request) are:
Object getCredential(Context, GetCredentialRequest, Continuation
