使用CredentialManager实现Google登录时触发取消异常求助

• 问题现象：在Android应用中通过CredentialManager实现Google登录功能，点击登录按钮弹出账号选择弹窗，选择Gmail账号时提示“activity is cancelled by the user”，抛出异常androidx.credentials.exceptions.GetCredentialCancellationException: activity is cancelled by the user
• GCP配置说明：使用web_client_id进行配置，同一应用原本存在两个Android ClientID，已删除AppSigningKey（SHA-1）对应的client_id，仅保留上传密钥库（SHA-1）对应的client_id

相关实现代码如下：

val googleIdOption: GetSignInWithGoogleOption = GetSignInWithGoogleOption.Builder(WEB_CLIENT_ID).build()
val request: GetCredentialRequest = GetCredentialRequest.Builder().addCredentialOption(googleIdOption).build()

R.id.btn_googleSignUp -> {
    val credentialManager = CredentialManager.create(this@SignUpActivity)
    coroutineScope.launch {
        try {
            Log.e("request.. ===", request.toString())
            val result = credentialManager.getCredential(
                request = request,
                context = this@SignUpActivity,
            )
            handleSignIn(result)
        } catch (e: GetCredentialCancellationException) {
            Log.e("CredentialCancelException ===", e.message.toString())
        } catch (e: GetCredentialException) {
            Log.e("GetCredential ===", e.message.toString())
        } catch (e: Exception) {
            Log.e("Exception ===", e.message.toString())
        }
    }
}

fun handleSignIn(result: GetCredentialResponse) {
    // Handle the successfully returned credential.
    val credential = result.credential
    when (credential) {
        is PublicKeyCredential -> {
            // Share responseJson such as a GetCredentialResponse on your server to
            // validate and authenticate
           //responseJson = credential.authenticationResponseJson
        }

        is PasswordCredential -> {
            // Send ID and password to your server to validate and authenticate.
            val username = credential.id
            val password = credential.password
        }

        is CustomCredential -> {
            if (credential.type == GoogleIdTokenCredential.TYPE_GOOGLE_ID_TOKEN_CREDENTIAL) {
                try {
                    // Use googleIdTokenCredential and extract id to validate and
                    // authenticate on your server.
                    val googleIdTokenCredential = GoogleIdTokenCredential
                        .createFrom(credential.data)
                } catch (e: GoogleIdTokenParsingException) {
                    Log.e("Invalid GoogleId", "Received an invalid google id token response", e)
                }
            } else {
                // Catch any unrecognized custom credential type here.
                Log.e("Unexpected", "Unexpected type of credential")
            }
        }

        else -> {
            // Catch any unrecognized credential type here.
            Log.e("Invalid GoogleID", "Unexpected type of credential")
        }
    }
}
