Android CredentialManager弹窗点击外部关闭无回调问题求助

使用Java开发安卓游戏，通过CredentialManager唤起Google账号选择弹窗时出现异常行为：

• 点击弹窗内的「取消」按钮，会正常触发onError回调并抛出GetCredentialCancellationException
• 点击弹窗外部关闭弹窗时，CancellationSignal.OnCancelListener、onResult、onError均无任何回调触发
• 该问题仅在**三星Galaxy M53 5G（Android 14，One UI 6.0）**上出现，**三星Galaxy Tab A（2018，Android 10，One UI 2.1）**可正常触发GetCredentialCancellationException

核心疑问 #

1. CancellationSignal.onCancel是否仅在主动调用.cancel()时才会触发？
2. 如何处理弹窗外部点击关闭的情况？

关于CancellationSignal的说明 #

CancellationSignal.OnCancelListener确实仅在主动调用cancellationSignal.cancel()时触发，系统弹窗的外部点击关闭并不会自动触发这个信号，这是设计预期。

处理外部点击关闭的方案 #

方案1：升级Credentials库版本 #

优先升级androidx.credentials相关依赖到最新稳定版，Google可能已经修复了高版本系统上的回调不一致问题：

implementation "androidx.credentials:credentials:1.6.0"
implementation "androidx.credentials:credentials-play-services-auth:1.6.0"
implementation "com.google.android.libraries.identity.googleid:googleid:1.2.0"

方案2：监听页面生命周期回调 #

如果升级库后问题仍存在，可通过监听当前页面的生命周期判断弹窗是否被外部关闭：

1. 新增标记位记录弹窗状态：

private boolean isCredentialPickerShowing = false;

2. 调用getCredentialAsync时设置标记：

isCredentialPickerShowing = true;
credentialManager.getCredentialAsync(...);

3. 在Activity的onResume中检查并处理：

@Override
protected void onResume() {
    super.onResume();
    if (isCredentialPickerShowing) {
        // 弹窗已关闭且未触发回调，执行取消逻辑
        handleCredentialCancellation();
        isCredentialPickerShowing = false;
    }
}

private void handleCredentialCancellation() {
    log(LOG_TAG, "Credential picker closed via outside tap");
    // 这里添加取消后的处理逻辑，比如重置状态、提示用户等
}

注意：需要在onResult和onError回调中也重置isCredentialPickerShowing = false;，避免误判。

方案3：自定义弹窗拦截（不推荐） #

不建议通过自定义弹窗或拦截触摸事件的方式处理，会破坏系统原生的账号选择体验，优先使用前两种方案。
