Change In your My APi Interface for Retrofit

public interface ApiInterface {

    @Headers( "Content-Type: application/json; charset=utf-8")
    @POST("re_clientdata")


    Call<String> savePost(@Body RequestBody req);
}

Also change Mainactivity code like this

protected void onCreate(Bundle savedInstanceState) {

                super.onCreate(savedInstanceState);
                setContentView(R.layout.activity_main);

                 sendPost(jRequest);

        }

        public void sendPost(JSONObject requestobject) {
            Log.e("requestobject",requestobject.toString());

              RequestBody myreqbody = null;
                try {
                     myreqbody = RequestBody.create(okhttp3.MediaType.parse("application/json; charset=utf-8"),
                            (new JSONObject(String.valueOf(requestobject))).toString());
                } catch (JSONException e) {
                    e.printStackTrace();
                }

                Call<String> call =mAPIService.savePost(myreqbody);


            call.enqueue(new Callback<String>() {
                @Override
                public void onResponse(Call<String>callback,Response<String>response) {
                    String res = response.body();
                    Log.e("DEMO", "post submitted to API." + response);
                }
                @Override
                public void onFailure(Call<String> call, Throwable t) {
                    Log.e("DEMO", "Unable to submit post to API.",t);
                    Log.e("call", String.valueOf(call));
                }
            });

        }
