convert String publickey to RSA publickey

I'm trying to convert string public key to publickey with modulus and exponent. but how come it doesnt works?

this is my code

     public void toPubKey(String filename,String sms) throws NoSuchAlgorithmException, NoSuchProviderException, InvalidKeySpecException, IOException{
    byte[]keyBytes=sms.getBytes();
    byte[]decode = Base64.encode(keyBytes, Base64.DEFAULT);
    KeyFactory fact = KeyFactory.getInstance("RSA");
    X509EncodedKeySpec x509KeySpec = new X509EncodedKeySpec(decode);
    PublicKey pubKey2 = (PublicKey)fact.generatePublic(x509KeySpec);
    saveToFile(filename,pubKey2);

any problem with my code?

Perhaps you meant your code to be:

byte[]decode = Base64.decode(keyBytes, Base64.DEFAULT);

Change encode to decode.
