// Important: Don't forget to include the call to System.loadLibrary // as shown at the bottom of this code sample. package com.test; import android.app.Activity; import com.chilkatsoft.*; import android.widget.TextView; import android.os.Bundle; public class SimpleActivity extends Activity { private static final String TAG = "Chilkat"; // Called when the activity is first created. @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); CkCert cert = new CkCert(); boolean success = cert.LoadFromFile("qa_data/certs/sample.cer"); if (success == false) { Log.i(TAG, cert.lastErrorText()); return; } // Get issuer information: // ----------------------------------------------------------------------- // (Not all subject fields may exist depending on the issuer certificate.) // ----------------------------------------------------------------------- // Issuer DN (Distinguished Name, i.e. all the Issuer subject parts) Log.i(TAG, "DN: " + cert.issuerDN()); // Common Subject parts: // Issuer Common Name Log.i(TAG, "CN: " + cert.issuerCN()); // Issuer Country Log.i(TAG, "C: " + cert.issuerC()); // Issuer Email address Log.i(TAG, "E: " + cert.issuerE()); // Issuer Locality Log.i(TAG, "L: " + cert.issuerL()); // Issuer Organization Log.i(TAG, "O: " + cert.issuerO()); // Issuer Organizational Unit Log.i(TAG, "OU: " + cert.issuerOU()); // Issuer State Log.i(TAG, "S: " + cert.issuerS()); } static { System.loadLibrary("chilkat"); // Note: If the incorrect library name is passed to System.loadLibrary, // then you will see the following error message at application startup: //"The application <your-application-name> has stopped unexpectedly. Please try again." } } |
