Проблема с реализацией входа в Google в ViewModel ⇐ Android

[Anonymous]

У меня возникла проблема с реализацией входа в Google в приложении Android. У меня есть два фрагмента кода: первый работает правильно, а второй дает сбой во время вызова credentialManager.getCredential(context = context, request = request).
Первый код (рабочий)

Код: Выделить всё

class GoogleAuthClient(
private val context: Context,
private val credentialManager: CredentialManager,
private val onSignInComplete: () -> Unit,  // 로그인 완료 콜백 추가
private val onSignOutComplete: () -> Unit  // 로그아웃 완료 콜백 추가
) {
companion object {
private const val TAG = "GoogleAuthClient"
}

fun handleSignIn(result: GetCredentialResponse) {
val credential = result.credential

when {
credential.type == GoogleIdTokenCredential.TYPE_GOOGLE_ID_TOKEN_CREDENTIAL -> {
try {
val googleIdTokenCredential =
GoogleIdTokenCredential.createFrom(credential.data)

val idToken = googleIdTokenCredential.idToken
val email = googleIdTokenCredential.id
val displayName = googleIdTokenCredential.displayName

Log.d(TAG, "Login successful: $email")
Toast.makeText(context, "Welcome, $displayName!", Toast.LENGTH_SHORT).show()
onSignInComplete()  // 로그인 완료 알림

} catch (e: GoogleIdTokenParsingException) {
Log.e(TAG, "Invalid Google ID token", e)
Toast.makeText(context, "Login failed: Invalid token", Toast.LENGTH_SHORT)
.show()
}
}

else ->  {
Log.e(TAG, "Unexpected credential type")
Toast.makeText(context, "Login failed: Unexpected error", Toast.LENGTH_SHORT).show()
}
}
}

fun signOut() {
CoroutineScope(Dispatchers.Main).launch {
try {
credentialManager.clearCredentialState(
ClearCredentialStateRequest(
ClearCredentialStateRequest.TYPE_CLEAR_CREDENTIAL_STATE
)
)
Toast.makeText(context, "Signed out successfully", Toast.LENGTH_SHORT).show()
onSignOutComplete()  // 로그아웃 완료 알림
} catch (e: Exception) {
Log.e(TAG, "Logout failed", e)
Toast.makeText(context, "Logout failed", Toast.LENGTH_SHORT).show()
}
}
}
}
class MainActivity : ComponentActivity() {
private lateinit var googleAuthClient: GoogleAuthClient
private lateinit var credentialManager: CredentialManager
private var isSignedIn = false
private lateinit var signInOutText: TextView

override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)

signInOutText = TextView(this).apply {
text = "Sign In"
textSize = 18f
setPadding(32, 32, 32, 32)
setOnClickListener { handleSignInOutClick() }
}
setContentView(signInOutText)

credentialManager = CredentialManager.create(this)
googleAuthClient = GoogleAuthClient(
this,
credentialManager,
onSignInComplete = {
isSignedIn = true
signInOutText.text = "Sign Out"
},
onSignOutComplete = {
isSignedIn = false
signInOutText.text = "Sign In"
}
)
}

private fun handleSignInOutClick() {
if (!isSignedIn) {
signInWithGoogle()
} else {
googleAuthClient.signOut()
}
}

private fun signInWithGoogle() {
val nonce = generateNonce()
val signInWithGoogleOption = GetSignInWithGoogleOption.Builder(
"909240456210-gomip46dc5200lbd8vdrs2ii94clss4t.apps.googleusercontent.com")
.setNonce(nonce)
.build()
Log.d("haha", "signInWithGoogleOption 성공")

val request = GetCredentialRequest.Builder()
.addCredentialOption(signInWithGoogleOption)
.build()

Log.i("haha", "GetCredentialRequest 성공")

CoroutineScope(Dispatchers.Main).launch {
try {
val result = credentialManager.getCredential(
request = request,
context = this@MainActivity
)
Log.d("haha", "getCredential 성공")

googleAuthClient.handleSignIn(result)
} catch (e: Exception) {
println("Login failed: ${e.message}")
}
}
}

private fun generateNonce(): String {
val randomBytes = ByteArray(32)
SecureRandom().nextBytes(randomBytes)
return randomBytes.joinToString("") { "%02x".format(it) }
}
}

Второй код (не работает)

onNavigateToGenderAndAgeGroup: (Map) -> Unit,
onNavigateToQuote: () ->  Unit

composable(route = "login") {

LoginScreen(
loginViewModel = loginViewModel,
onNavigateToGenderAndAgeGroup = {
pendingUserMap?.let { onNavigateToGenderAndAgeGroup(it) }
},
onNavigateToQuote = onNavigateToQuote
)

Во втором коде, когда я вызываю credentialManager.getCredential(context = context, request = request), он выдает ошибку. Однако я убедился, что настройки GCP и конфигурации SHA-1 верны, поскольку первый код отлично работает в том же проекте.
Что может быть причиной credentialManager.getCredential вызывает сбой во втором коде?
в logcat отображается ошибка «[28444] Консоль разработчика настроена неправильно».
Любой идеи или предложения о том, как устранить эту неполадку буду очень признателен!
