将我的应用定位到Android 9预览时，我在尝试生成 KeyPair 时出错。我使用以下代码：
public void createKeysM(String alias, boolean requireAuth) {
try {
KeyPairGenerator keyPairGenerator = KeyPairGenerator.getInstance(
KeyProperties.KEY_ALGORITHM_RSA, SecurityConstants.KEYSTORE_PROVIDER_ANDROID_KEYSTORE);
keyPairGenerator.initialize(
new KeyGenParameterSpec.Builder(
alias,
KeyProperties.PURPOSE_ENCRYPT | KeyProperties.PURPOSE_DECRYPT)
.setAlgorithmParameterSpec(new RSAKeyGenParameterSpec(1024, F4))
.setBlockModes(KeyProperties.BLOCK_MODE_CBC)
.setEncryptionPaddings(KeyProperties.ENCRYPTION_PADDING_RSA_PKCS1)
.setDigests(KeyProperties.DIGEST_SHA256,
KeyProperties.DIGEST_SHA384,
KeyProperties.DIGEST_SHA512)
.setUserAuthenticationRequired(requireAuth)
.build());
KeyPair keyPair = keyPairGenerator.generateKeyPair();
Log.d(TAG, "Public Key is: " + keyPair.getPublic().toString());
} catch (NoSuchProviderException | NoSuchAlgorithmException | InvalidAlgorithmParameterException e) {
throw new RuntimeException(e);
}
}
我在 KeyPair keyPair = keyPairGenerator.generateKeyPair（）;
行中收到错误我将堆栈跟踪放在问题的最后。有人遇到过这个问题吗？
感谢您的帮助！

在Google跟踪器中打开了一个错误。你可以在这里跟踪它：
