Android™

// 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);

    boolean success = false;

    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    // You can verify a signed DLL or EXE.
    String path = "c:/someDir/something.dll";

    CkCodeSign codeSign = new CkCodeSign();

    // If successful, the signature is removed from the EXE or DLL file.
    success = codeSign.RemoveSignature(path);
    if (success == false) {
        Log.i(TAG, codeSign.lastErrorText());
        }

    Log.i(TAG, "success: " + String.valueOf(success));

  }

  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."
