Base64 decoding of JSONObject in Android 2.1

I need to decode JSONObject in Android 2.1 with Base64.I know that Base64 class supports Android 2.2+,that's why I include the source code in my project.So I need 开发者_如何学Pythonto do something like that :

JSONObject clientHash = new JSONObject();
byte[] tmpSecData = Base64.decode(clientHash.getJSONObject("client_auth_hash"));

Any suggestions how to do that or is it possible?

Lets try it,

1. Convert the clientHash.getJSONObject("client_auth_hash") in String then byteArray,

2. then use,

   byte temp[];
   Base64 b = new Base64();
   String jsonString = clientHash.getJSONObject("client_auth_hash").toString();
   temp = b.decode(jsonString.getBytes());
   

3. then use your temp byte[].

Hope this will help you. If its work then inform me. Thanx.
