Base64 encoder and decoder

Question

Is there a base-64 decoder and encoder for a String in Android?

Answer 1

This is an example of how to use the Base64 class to encode and decode a simple String value.

// String to be encoded with Base64 String text = "Test"; // Sending side byte[] data = null; try {     data = text.getBytes("UTF-8"); } catch (UnsupportedEncodingException e1) {     e1.printStackTrace(); } String base64 = Base64.encodeToString(data, Base64.DEFAULT);  // Receiving side byte[] data1 = Base64.decode(base64, Base64.DEFAULT); String text1 = null; try {     text1 = new String(data1, "UTF-8"); } catch (UnsupportedEncodingException e) {     e.printStackTrace(); } 

This excerpt can be included in an Android activity.

Answer 2

See android.util.Base64

It seems that this was added in API version 8 or android 2.2 so it will not be available on the older platforms.

But the source of it is at android/util/Base64.java so if needed one could just copy it unchanged for older versions.
