Android C/C++ Libraries

// 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;

    //  Generate a 1024-bit key.  Chilkat RSA supports
    //  key sizes ranging from 512 bits to 4096 bits.
    //  Note: Starting in Chilkat v9.5.0.49, RSA key sizes can be up to 8192 bits.

    //  an 8192-bit key.

  }
