On Android, use the static methods of the android.util.Base64 utility class. The referenced documentation says that the Base64 class was added in API level 8 (Android 2.2 (Froyo)).

import android.util.Base64;

byte[] encodedBytes = Base64.encode("Test".getBytes());
Log.d("tag", "encodedBytes " + new String(encodedBytes));

byte[] decodedBytes = Base64.decode(encodedBytes);
Log.d("tag", "decodedBytes " + new String(decodedBytes));
