Hey, We have been using XMLRPC for android and it was working well until we got our hands dirty with Base64 encoding for byte[] (images) -- (we did base64_string.replace("/","$$") for transmission). We have tried undoing the changes and its looking an XMLRPC error. We are getting the following error in the DDMS: 06-10 23:27:02.970: DEBUG/Test(343): org.xmlrpc.android.XMLRPCFault: XMLRPC Fault: [code 0] 06-10 23:27:02.970: DEBUG/Test(343): at org.xmlrpc.android.XMLRPCClient.callEx(XMLRPCClient.java:308) 06-10 23:27:02.970: DEBUG/Test(343): at org.xmlrpc.android.XMLRPCMethod.run(XMLRPCMethod.java:33) Just before this I checked the body (xml message -- which is perfect) and the response received: 06-10 23:27:02.940: INFO/System.out(343): Response received: org.apache.http.message.BasicHttpResponse@437762f8 Since it the message is not even reaching our cloud, the issue is with XMLRPC for android. Any help will be most appreciated. Thanks Best Sameer
