Android中getCredentialAsync错误抛出NoCredentialException问题求助

我正在使用Java开发一款Android游戏，通过CredentialManager提示用户选择Google账号。代码运行正常，但在以下两种场景下，系统抛出的是NoCredentialException，而非更合适的异常（如ConnectionException或通用InterruptedException）：

• 出现连接问题时（例如超时、地铁内无网络）；
• 调用getCredentialAsync后按下设备Home键，随后返回应用（整个操作仅需数秒）。

public void signIn_credentialManager() {
    String nonce = randomNonce();
    GetCredentialRequest request;
    googleIdOption = new GetGoogleIdOption.Builder()
        .setFilterByAuthorizedAccounts(false)
        .setServerClientId("...")
        .setAutoSelectEnabled(true)
        .setNonce(nonce)
        .build();
    request = new GetCredentialRequest.Builder()
        .addCredentialOption(googleIdOption)
        .build();
    log(LOG_TAG, "credentialManager.getCredentialAsync");
    credentialManager.getCredentialAsync(
        context,
        request,
        new CancellationSignal(),
        executor,
        new CredentialManagerCallback<GetCredentialResponse, GetCredentialException>() {
            @Override
            public void onResult(GetCredentialResponse result) {
                log(LOG_TAG, "CredentialManagerCallback onResult");
            }
            @Override
            public void onError(@NonNull GetCredentialException e) {
                log(LOG_TAG, "CredentialManagerCallback Error!");
                e.printStackTrace();
                
                if(e instanceof NoCredentialException) {
                    // HERE    
                }
            }
        }
    );
}

设备信息 #

• 设备：三星Galaxy M53 5G
• 系统：Android 14
• Google Play系统更新：2024年5月1日
• One UI版本：6.0

疑问点 #

1. 为何会抛出错误的异常类型？
2. 获取可用账号是否需要发起网络请求？按常理它应仅读取本地设备数据，但恢复网络后重试即可正常运行，这似乎矛盾。
3. 应用切换后台后是否应恢复该操作？

我需要正确处理所有错误场景，但异常类型错误导致无法实现。请问我是否存在操作失误？

补充说明 #

无法通过getCause()获取根源异常，因为该NoCredentialException并非由其他异常引发，栈信息如下：
