我正在使用加密共享首选项来加密首选项数据。我通过以下方式使用它：

val masterKey = MasterKey.Builder(context)
                .setKeyScheme(MasterKey.KeyScheme.AES256_GCM)
                .build()

        val sharedPreferences = EncryptedSharedPreferences.create(
                context,
                prefName,
                masterKey,
                EncryptedSharedPreferences.PrefKeyEncryptionScheme.AES256_SIV,
                EncryptedSharedPreferences.PrefValueEncryptionScheme.AES256_GCM
        )

我从我的应用程序类访问这个安全共享的首选项实例。这在我的生产应用程序中导致了 ANR 问题。

此行为观察器主要在 Android 9 和 10 上。

cipher.init周围报告了 Andorid 错误。有什么办法可以解决这个问题。它导致我的应用程序在 Playstore 上出现不良行为。
