我正在使用 KeyGenParameterSpec 来定义我的密钥规范。当我运行应用程序时，我在日志中收到以下错误：
原因：java.lang.ClassNotFoundException：在路径上找不到类“android.security.keystore.KeyGenParameterSpec$Builder”：DexPathList[[zip file“/data/app/com.rsa.mobile.transactionsigningsdk-1/base .apk"],nativeLibraryDirectories=[/vendor/lib64, /system/lib64]]
下面是我的 MainActivity.java：

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)

}
});
}
@Override

// 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

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(

.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

//remove
Log.i("Testing Message","Inside Enroll()");
Log.i("Testing Message", String.valueOf(pk));
//To Ask

return new DeviceEnrollmentResponse(null, StatusReasonCode.UNKNOWN_ERR);

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