我的证书捆绑ID与Firebase控制台中输入的捆绑ID不匹配,当我尝试上传云消息传递证书时.我收到错误:

证书中的Bundle ID与您输入的Bundle ID不匹配.

我的问题是,在Xcode,Apple Developer Portal和Firebase Console中匹配我项目的Bundle ID的最佳方法是什么？我是否在iTunes Connect中创建新应用,然后生成新证书？我可以在Firebase控制台或Apple Developer Portal中更改Bundle ID吗？或者,我是否可以使用匹配的捆绑包ID创建新证书,就像在我的Firebase控制台中一样,而无需在iTunes Connect中创建新的应用程序？

我将 Fragment 与 ViewPager2 一起使用，我注意到在运行 Android 8 或 9 的小米、宇龙、华硕、vivo 等设备中出现了两个相关的 IllegalStateExceptions（我自己无法重现）：

我尝试在Android Studio中构建一个模块。它似乎可以在设备上运行，但是当我尝试构建APK时出现错误：

我有一个像这样的密封类：

sealed class SealedClass {

    object Object1 : SealedClass()
    object Object2 : SealedClass()
    object Object3 : SealedClass()

    data class DataClass(val sealedClass: SealedClass, val anotherDataType: AnotherDataType? = null)
}

我想在 Bundle 中传递我的数据类，就像我们通常将值传递给一个新片段一样，如下所示：

@JvmStatic
fun newInstance(dataClass: DataClass): Fragment {
    val fragment = Fragment()

    val args = Bundle(1)
    args.putParcelable("DATA_CLASS", dataClass)
    fragment.arguments = args

    return fragment
}

我不知道该怎么做。到目前为止，我读到的是人们使用@Parcelize注释，这是我试图避免的 Kotlin 的一个实验性功能。另一种方法是通过 Parcelable 扩展数据类并实现 Parcelable 方法，但由于我使用自定义类作为 DataClass 中的参数（例如 SealedClass），我不知道如何在 Parcelable 实现中读取/写入这些值。这不是一个正确的方法吗？

我自己无法重现此问题，但我在运行小米 MI 9 的生产中注意到此问题Android 10。以下是我使用的ViewPager2和RecyclerView版本：

androidx.recyclerview:recyclerview:1.1.0 
androidx.viewpager2:viewpager2:1.0.0

我有使用Firebase的注册流程。当我检查数据库中是否已存在电子邮件时，如下所示：

refUsers.queryOrdered(byChild: "email").queryEqual(toValue: emailText).observeSingleEvent(of: .value, with: { snapshot in

      if (snapshot.value is NSNull) {
            print("Unique email")

            // Move to Password View.
            let passwordViewController = self.storyboard?.instantiateViewController(withIdentifier: "PasswordViewController") as! PasswordViewController

            self.navigationController?.present(passwordViewController, animated: true, completion: nil)

            // Pass the emailText to the last View of the flow.
            self.singleton.sharedInstance.emailText = emailText!

      }
      else {
            print("Duplicate email")
      }  
})

问题是，我没有查看数据库中的/ users的权限，原因是我的规则是：

{
  "rules": {
    ".read": "auth != null",
    ".write": "auth != null"
  }
}

我知道我可以找到一封电子邮件是否是重复的，Auth.auth().createUser但不仅仅是我要检查的注册流程中的电子邮件。对于唯一的用户名，我也使用相同的方法。我该如何实现？
