不使用 adb 时出现 Android KeyStore Unknown 错误

如何解决不使用 adb 时出现 Android KeyStore Unknown 错误

当我在没有 adb/电缆连接到我的电脑的情况下使用应用程序时，我很难让我的代码运行。 我试图找到我可以在 googles pixel 4a StrongBox 芯片中存储的最大数量的密钥。所以我的代码看起来像这样：

do {

    val alias = generateTestKeyPair(kPairGenerator)
    checkGeneratedKeyAvailable(alias,fwriter)
    Log.i(
        TAG,"challenge: generated: ${result} keys (${result * keySize} bits / ${result * keySize / 8} bytes)"
    )
    if (result % 10 == 0) { // Check every 10 generated keys to ensure older keys are still in StrongBox
        val validateRandomSignature = validateRandomSignature(fwriter)
        if (!validateRandomSignature)
            throw IllegalStateException("Signature of random Key can not be validated. -> Key not found??")
    }
} while (true)

生成测试密钥对：

private fun generateTestKeyPair(kPairGenerator: KeyPairGenerator): String {
    val parameterSpec = KeyGenParameterSpec.Builder(
        "max-key-aes-${++result}",KeyProperties.PURPOSE_SIGN or KeyProperties.PURPOSE_VERIFY
    ).run {
        setKeySize(keySize)
//            setKeyValidityEnd(
//                Date.from(
//                    Instant.now().plus(10,ChronoUnit.HOURS)
//                )
//            )
        setDigests(KeyProperties.DIGEST_SHA256)
        setSignaturePaddings(KeyProperties.SIGNATURE_PADDING_RSA_PKCS1)
        setIsStrongBoxBacked(true)
        build()
    }
    kPairGenerator.initialize(parameterSpec)
    kPairGenerator.genKeyPair()
    return parameterSpec.keystoreAlias
}

我的问题是，在设备上的循环中生成 1-3 个密钥后，我总是收到此错误/异常，而未将其连接到 PC/使用 adb：
