I got the solution from the hint given by Mr.Jackson Chengalai.

Create a Okhttp request interceptor

private static class PicassoInterceptor implements Interceptor {

    @Override
    public Response intercept(Chain chain) throws IOException {

        final MediaType JSON
                = MediaType.parse("application/json; charset=utf-8");
        Map map = new HashMap();
        map.put("session_id", session_id);
        map.put("image", image);
        String requestJsonBody = new Gson().toJson(map);
        RequestBody body = RequestBody.create(JSON, requestStringBody);
        final Request original = chain.request();
        final Request.Builder requestBuilder = original.newBuilder()
                .url(url)
                .post(body);
        return chain.proceed(requestBuilder.build());
    }
}

Create a Okhttp client add this interceptor

OkHttpClient okHttpClient = new OkHttpClient();
okHttpClient.interceptors().add(new PicassoInterceptor());

Create a Dowloader using this okhttp client

OkHttpDownloader = downloader = new OkHttpDownloader(okHttpClient)

Build Picasso using this downloader

Picasso picasso = new Picasso.Builder(context).downloader(downloader ).build();
