i have used

jsonstr = new JSONStringer().object().key("Text")
                            .value(msg).key("Files").array().object().key(
                                    "ContentType").value("image/png").key(
                                    "Content").value(enimg)
                            .endObject().endArray().key("AuthToken").value(token)
                            .endObject();

but the server is giving me fault message in return, not accepting the data.

Answer 1

actually i was doing the right thing..everything was OK.. the problem was with org.json package it was not accurate with Base64 string

i switched to another library and all worked..
