Ajay Satpati's questions

我正在尝试在我的 Kotlin Jetpack Compose 中使用 Firebase 添加 Google 登录。但出现了“没有可用凭据”的问题。我想显示 Google 帐户列表，然后选中该帐户，系统会显示登录成功的提示。我尝试了不同的方法，但问题依旧。

            Row(
                horizontalArrangement = Arrangement.Center
            ) {
                val context = LocalContext.current

                // Initialize Credential Manager
                val credentialManager = CredentialManager.create(context)

                // Configure Credential Request
                val request = GetCredentialRequest.Builder()
                    .addCredentialOption(
                        GetGoogleIdOption.Builder()
                            .setServerClientId(context.getString(R.string.default_web_client_id))
                            .setFilterByAuthorizedAccounts(true)
                            .setAutoSelectEnabled(true)
                            .build()
                    )
                    .build()

                var showToast by remember { mutableStateOf(false) }
                var showFailureToast by remember { mutableStateOf(false) }
                // Google Sign-In Icon
                Icon(
                    painter = painterResource(id = R.drawable.google_search_logo),
                    contentDescription = "Google Icon",
                    modifier = Modifier
                        .size(windowWidthFraction(0.075f))
                        .clickable {

                                    val credential = response.credential
                                    if (credential is CustomCredential && credential.type == GoogleIdTokenCredential.TYPE_GOOGLE_ID_TOKEN_CREDENTIAL) {
                                        val googleIdTokenCredential = GoogleIdTokenCredential.createFrom(credential.data)
                                        val idToken = googleIdTokenCredential.idToken

我正在尝试在 Kotlin Jetpack 中使用 Firebase 身份验证设置 Google 登录。不知何故，我无法获取 googleIdToken。

我尝试了很多方法，仍然无法解决。我尝试过其他方法，但它们都被弃用了。

Row(
    horizontalArrangement = Arrangement.Center
) {
    val context = LocalContext.current

    // Initialize Credential Manager
    val credentialManager = CredentialManager.create(context)

    // Configure Credential Request
    val request = GetCredentialRequest.Builder()
        .addCredentialOption(
            GetGoogleIdOption.Builder()
                .setServerClientId(context.getString(R.string.default_web_client_id))
                .build()
        )
        .build()

    // Google Sign-In Icon
    Icon(
        painter = painterResource(id = R.drawable.google_search_logo),
        contentDescription = "Google Icon",
        modifier = Modifier
            .size(LocalConfiguration.current.screenWidthDp.dp * 0.075f)
            .clickable {
                CoroutineScope(Dispatchers.IO).launch {
                    try {
                        val response = credentialManager.getCredential(context, request)
                        val googleIdToken = response.googleIdToken // Adjusted to retrieve the token
                        if (googleIdToken != null) {
                            val firebaseCredential = GoogleAuthProvider.getCredential(googleIdToken, null)
                            FirebaseAuth.getInstance().signInWithCredential(firebaseCredential)
                                .addOnCompleteListener { task ->
                                    if (task.isSuccessful) {
                                        Log.d("SignIn", "Sign-in successful!")
                                        // Perform navigation or update UI
                                    } else {
                                        Log.e("SignIn", "Sign-in failed: ${task.exception}")
                                    }
                                }
                        } else {
                            Log.e("SignIn", "Google ID token is null")
                        }
                    } catch (e: Exception) {
