Answer 1

My version to get secret shared preference :

private fun getSecretSharedPref(context: Context): SharedPreferences {
    val masterKey = MasterKey.Builder(context)
            .setKeyScheme(MasterKey.KeyScheme.AES256_GCM)
            .build()

    return EncryptedSharedPreferences.create(context,
            "secret_shared_prefs",
            masterKey,
            EncryptedSharedPreferences.PrefKeyEncryptionScheme.AES256_SIV,
            EncryptedSharedPreferences.PrefValueEncryptionScheme.AES256_GCM
    )
}
