android - 在路径 : DexPathList for KeyGenParameterSpec$Builder 上找不到类

Question

我正在使用 KeyGenParameterSpec 来定义我的 key 规范。当我运行应用程序时，我在日志中收到以下错误:

Caused by: java.lang.ClassNotFoundException: Didn't find class "android.security.keystore.KeyGenParameterSpec$Builder" on path: DexPathList[[zip file "/data/app/com.rsa.mobile.transactionsigningsdk-1/base.apk"],nativeLibraryDirectories=[/vendor/lib64, /system/lib64]]

下面是我的 MainActivity.java:

 package com.rsa.mobile.transactionsigningsdk;
import android.os.Bundle;
import android.support.design.widget.FloatingActionButton;
import android.support.design.widget.Snackbar;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.util.Log;
import android.view.View;
import android.view.Menu;
import android.view.MenuItem;

import com.rsa.mobile.transactionsigningsdk.enrollment.DeviceEnrollmentHelper;

public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);

    Log.i("Testing message", "App started");
    DeviceEnrollmentHelper deh =new DeviceEnrollmentHelper();
    deh.enroll();
    Log.i("Testing message", "Job Done");


    FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
    fab.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
                    .setAction("Action", null).show();
        }
    });
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.menu_main, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();

    //noinspection SimplifiableIfStatement
    if (id == R.id.action_settings) {
        return true;
    }

    return super.onOptionsItemSelected(item);
}

}

下面是从 MainActivity.java 调用的代码:

 public DeviceEnrollmentResponse enroll() {

    if(isEnrolled()) {
        return new DeviceEnrollmentResponse(null,StatusReasonCode.DEVICE_ALREADY_ENROLLED);
    }
    else{
        try {
            KeyPairGenerator keyPairGenerator = KeyPairGenerator.getInstance(
                    "RSA", "AndroidKeyStore");

            /*KeyPairGeneratorSpec spec = new KeyPairGeneratorSpec.Builder(android.content.Context this)
                    .setAlias("trsdk")
                    .setSubject(new X500Principal("CN=Sample Name, O=Android Authority"))
                    .setSerialNumber(BigInteger.ONE)
                    .setKeySize(KEY_SIZE)
                    .build();*/
            keyPairGenerator.initialize(
                    new KeyGenParameterSpec.Builder(
                            "trsdk",
                            KeyProperties.PURPOSE_SIGN)
                            .setAlgorithmParameterSpec(new ECGenParameterSpec("secp256r1"))
                            .setDigests(KeyProperties.DIGEST_SHA256,
                                    KeyProperties.DIGEST_SHA384,
                                    KeyProperties.DIGEST_SHA512)
                            .setUserAuthenticationRequired(true)
                            .build());
            KeyPair keyPair = keyPairGenerator.generateKeyPair();
            //Get the public key from the KeyPair
            PublicKey pk=keyPair.getPublic();
            //remove
            Log.i("Testing Message","Inside Enroll()");
            Log.i("Testing Message", String.valueOf(pk));

            //To Ask
            if (pk==null){
                return new DeviceEnrollmentResponse(null, StatusReasonCode.UNKNOWN_ERR);
            }
            else{
                return new DeviceEnrollmentResponse(pk, StatusReasonCode.DEVICE_SUCCESSFULLY_ENROLLED);
            }

            } catch (InvalidAlgorithmParameterException e) {
                e.printStackTrace();
            } catch (NoSuchAlgorithmException e) {
                e.printStackTrace();
            } catch (NoSuchProviderException e) {
                e.printStackTrace();
            }
        }
    //To Ask
    return null;
}

下面是我的 AndroidMaifest.xml:

<?xml version="1.0" encoding="utf-8"?>

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"

    <activity
        android:name=".MainActivity"
        android:label="@string/app_name"
        android:theme="@style/AppTheme.NoActionBar" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

下面是应用程序 build.gradle:

apply plugin: 'com.android.application'

android { compileSdkVersion 23 buildToolsVersion "23.0.2"

defaultConfig {
    applicationId "com.rsa.mobile.transactionsigningsdk"

任何人都可以帮忙:我已经尝试清理项目，按照相关问题中的建议重新导入它。
提前致谢!

这是因为您使用的设备没有使用 API 23(Android 6.0 或更高版本)
