This is often due to inadvertently including a core library file in your application's project, when using an IDE (such as Eclipse). If you are sure you're not intentionally defining a core class, then this is the most likely explanation of what's going on.     – Mufrah Oct 16 '12 at 10:49

you can use this methods. compile 'commons-codec:commons-codec:1.3'

and i use android.util.Base64 for Android

incompatible / replacement

DatatypeConverter.parseHexBinary 
org.apache.commons.codec.binary.Hex.decodeHex(key.toCharArray());




DatatypeConverter.printBase64Binary(finalData);
android.util.Base64.encodeToString(finalData, 16) 



DatatypeConverter.parseBase64Binary(encodedInitialData);
org.apache.commons.codec.binary.Hex.decodeHex(key.toCharArray());

Android API provides Base64 to do the conversions you are looking for. However, I used Apache Codec as a compatibility library between different platforms for the client library to get around this issue.
