Android: the client obtains garbled data from the server.

Android: the client obtains garbled data from the server.
Send an HTTP request to the server. The received JSON package is response. Use String content = EntityUtils. toString (response. getEntity (), "UTF-8"); Chinese garbled characters are still involved in decoding, followed

        String name = new String(response.getBytes("iso-8859-1"), "UTF-8");  

It does not help. Think of the server as if it was coded with URLENCODER, with a try attitude behind return added a URLDecoder. decode (content, "UTF-8"); it really works! However, I still don't quite understand the differences between URLDecoder. decode (content, "UTF-8") and EntityUtils. toString (response. getEntity (), "UTF-8") during decoding. The following is the network code:
