Base64 Into SharedPreferences
06 Feb 2016Want to push and pull some Base64 from SharedPreferences? You’ll need to do some String to byte[] conversion to get it done. First, I (foolishly) tried using toString() on a byte[] but that won’t work! The String constructor saves the day!
// Encoding
String encodedString = new String(Base64.encode(string.getBytes(), Base64.DEFAULT), Charset.defaultCharset());
// Decoding - Base64.decode() this can throw an IllegalArgumentException so best to try-catch!
String decodedString = new String(Base64.decode(string.getBytes(), Base64.DEFAULT), Charset.defaultCharset());
