Hash value of same string is different in Android and Javascript

Question

The hash values of the same string is different in Javascript and Android for SHA-256:

Javascript Code:

var hashedPassword = CryptoJS.SHA256(userPassword);
var passwordText = hashedPassword.toString(CryptoJS.enc.Base64);

Android Code:

MessageDigest messageDigest = MessageDigest.getInstance("SHA-256");
byte[] hashedPassword = messageDigest.digest(userPassword.getBytes());
String hashedPasswordText = Base64.encodeToString(hashedPassword, Base64.DEFAULT).trim();

Output for String "beast":

In Javascript :

In Android :

Your Javascript output string looks like Base16, not Base64. In fact, they're identical after transformation. — ephemient

According to this answer CryptoJS.enc.Base64 requires another component. And if it does not find it it defaults to HEX.
