title: How to done Encrypt and Decrypt a string value in android?
body: <p>Hi I have done this task. But I have to clarify some thing. I did this encryption and decryption like <a href="https://stackoverflow.com/questions/8612460/how-to-decrypting-the-php-encrypted-string-using-android.">this</a> Now shat my question is, If I import <strong>android.util.Base64</strong> to my working class is enough for encoding and decoding or I have to include <strong>Base64.java</strong> class. When I remove Base64.java class it also works finely. So what is the purpose of Base64.java class? Can any body clarify me? Thanks in advance.</p>
