Base64 encoder and decoder
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();
}

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.
